东部电子材料有限公司
Since 1996, Dongbu has operated a powder production factory and a core production factory in Ansan, Ko-rea. At the powder production factory, raw materials are weighed, melted and atomized to powders. The powders are pulverized to a desired particle distribution, heat-treated, and insulated. On the other hand, at the core production factory, the insulated powders are pressed to cores, stress-relieved, infiltrated and proceeded to the final coating and inspection. Through the factory operation we have set all the standard procedures up and it has led to the production of more consistent and more reliable products.
We produce the magnetic core products of Moly-Permalloy Powder Cores (MPP), High Flux Powder Cores (HF), High Flux Prime Powder Cores (HF Prime), Ultra Flux Powder Cores (UF), Sendust Powder Cores (SDT), Power Flux Powder Cores (PF) which are made of metal alloy powders consisting of nickel, iron, aluminum, silicon, and molybdenum. Besides, new materials are possible at a customer’s request. In addition to toroidal cores, special shape cores such as E cores, U cores, and Block cores are also available for the re-newable energy market including the photovoltaic (PV) inverter market, and for the hybrid electric vehicle (HEV) and electric vehicle (EV) market. These products show the best performance in DC-superposition and core loss characteristics at high frequency and high current condition, which makes them quite suitable for a variety of power applications from simple chokes to sophisticated devices such as DC-DC converters and DC-AC inverters.
It is our constant mission to try to meet customers’ needs in terms of quality, cost and delivery. In addition, we’ll be the best, the only and the first in global magnetic powder core business by best practices based on six sigma methodology.

Core Identification
Apparent Inductance in 1000 turns
Name Code of Materials and Color of Toroidal Cores
Apparent inductance is value in mH/1000 turns.
(AL value is the inductance(nH) per turn squared.)
Each alloy powder cores of Dongbu is coated with epoxy resin and marked with a part number.
Sometimes, in the case of customer’s special requirement, some cores are coated with parylene coating.
A part number means core identification and it includes name code of materials, core outer diameter,
apparent inductance code temperature stability code and inductance tolerance band code.
Core identification for easy distinction is following as below.
Normally, name code of materials, outer diameter of bare core, apparent inductance in 1,000 turns and inductance
temperature stability are stamped on the outside of the core.
But, for customer order, tolerance band of apparent inductance is marked in packing label.

Magnetic Design FormulaThe inductance of a core and the number of turns can be calculated by using the following formula.
■Inductance of Wourd Cores
■Example) M040066A
■The relations of Permeability-Flux Density(B)-Magnetizing Force(H)
Where l = Inductance (μH) μ = core permeability n = number of turns a = core cross section area (cm2) = mean magnetic path length (cm) ln = inductance for N turns (μH) al = nominal inductance(nH/N2)
Where H = magnetizing force (Oersteds) n = number of turns I = peak magnetizing current (A) = mean magnetic path length (cm) bmax = maximum flux density (Gauss) erms = voltage across coil (V) a = core cross section area (cm2) f = frequency (Hz) μ = material permeability
n = 10 turns (our standard wound turns for M040066A)a = 0.100cm2 (please see the page ‘79’)ℓ = 2.380cm (please see the page ‘79’)ln = 66 x 102 x 10-3 = 6.60(μH)
ampere’s law : The law is the magnetic equivalent of Gauss’s law. It relates the circulating magnetic field
in a closed loop to the electric current passing through the loop
Faraday’s law : The law that defines the relationship of the voltage induced across the winding of a core to
the flux density within the core
(ampere’s law)

■Core Loss
Where rac = effective resistance (Ohm) a = hysteresis loss coefficient c = residual loss coefficient e = eddy current loss coefficient μ = same as before mentioned l = inductance bmax = maximum flux density f = frequency
n = 10 turns (our standard wound turns for M040066A)a = 0.100cm2 (please see the page ‘79’) = 2.380cm (please see the page ‘79’)ln = 66 x 102 x 10-3 = 6.60(μH)
Core : m040066a applied current : 3a
1) inductance Calculation at 0a
2) magnetizing force (H : oe) is calculated by ampere’ law to achieve the roll off
3) when the magnetizing force(H) is 15.8 oe, yielding 85% of initial permeability. Therefore, the Inductance at 3a is
L(3A) = 6.6 x 0.85 = 5.6(μH)
The total core losses are made up of three main
components : Hysteresis, eddy current and residual losses.
■Eddy current loss
■Residual loss
■Hysteresis loss

■Q Factor
■Physical Constant of Core
Where Q = quality factor ω = 2πf (Hz) l = inductance (H) rdc = DC winding resistance (Ohm) rac = resistance due to core losses (Ohm) rd = resistance due to winding dielectric losses (Ohm)
The Q factor is the ratio of reactance to the effective resistance and is often used as measure of performance.
So, the Q factor represents the effect of electrical resistance.
le = effective mean magnetic path length (cm)ae = effective core cross section area (cm2)ve = effective core volume (cm3)od = core outer diameter (cm)Id = core inner diamete (cm)HT = core height (cm)

The increase in surface temperature of a component in free-standing air due to the total power dissipation (both
copper and core loss). The following formula has been used to approximate temperature rise:
Nominal DC Resistance, in ohm/mH, at any given winding factor can be calculated by using the following equations:
The value of Rdc for any given winding factor can be computed as follows:
Total Power Loss = Copper Loss + Core Loss
Surface Area means in case of wound core

The DC bias current flowing through an inductor which
causes the inductance to drop by a specified amount
from the initial zero DC bias inductance value. Common
spec i f ied induc tance drop percentages include 10%
for ferrite cores and 20% for iron powder cores in en-
ergy storage applications. Also referred to as saturation
current.
A non-magnetic discontinuity in a ferro-magnetic circuit.
For example, the space between the poles of a magnet,
although filled with brass of wood and other non-mag-
netic material, is nevertheless called an air gap.
Core losses are caused by an altering magnetic field
in the core material. The losses are a function of the
operating frequency and the total magnetic flux swing.
The total core losses are made up of three main com-
ponents: Hysteresis, eddy current and residual losses.
These losses vary considerably from one magnetic ma-
terial to another. Applications such as higher power and
higher frequency switching regulators require careful
core selection to yield the highest inductor performance
by keeping the core losses to a minimum.
The temperature at which a magnetic material loses its
magnetic properties. The core's permeability typical ly
increases dramat ical ly as the core temperature ap-
proaches the curie temperature, which causes the in-
ductance to increase. The permeability drops to near
unity at the curie temperature, which causes the induc-
tance to drop dramatically. The curie point is the tem-
perature at which the initial permeability (μi) has dropped
to 10% of its value at room temperature.
(1)The voltage at which an insulator or dielectric rup-
tures, or at which ionization and conduction take place
in a gas or vapor. (2) The reverse voltage at which ava
l a n che b reakdown occu rs i n a semiconductor. (3)
Maximum AC or DC voltage that can be applied from
the input to output (or chassis) of a converter without
causing damage.
An inductor which is intended to filter, or 'choke', out
unwanted signals.
The power loss by current flowing through the winding.
The power loss is equal to the square of the current
multiplied by the resistance of the wire (i2xR). This power
loss is transferred into heat.

Direct current (DC) applied to the winding of a core in
addition to any time-varying current. Inductance with DC
bias is a common specification for powder cores. The
inductance will 'roll off' gradually and predictably with in-
creasing DC bias.
For a magnetic circuit constructed with an air gap, or
gaps , the permeability of a hypothetical homogeneous
material that would provide the same reluctance, or net
permeability.
Electro-Magnetic Interference - An unwanted electrical
energy in any form. EMI is often used interchangeably
with 'noise' and 'interference'.
Direct Current Resistance - The resistance of the induc-
tor winding measured with no alternating current. The
DCR is most often minimized in the design of an inductor.
The unit of measure is ohms and it is usually specified
as a maximum rating
Core losses associated with the electrical resistivity of
the magnetic material and induced voltages within the
material. Eddy currents are inversely proportional to ma-
terial resistivity and proportional to the rate of change of
flux density. Eddy current losses are present in both the
magnetic core and windings of an inductor. Eddy cur-
rents in the winding, or conductor, contribute to two main
types of losses: losses due to proximity effects and skin
effects. As for the core losses, an electric field around the
flux lines in the magnetic field is generated by alternat-
ing magnetic flux. This will result in eddy currents if the
magnetic core material has electrical conductivity. Loss-
es result from this phenomenon since the eddy currents
flow in a plane that is perpendicular to the magnetic
flux lines. Eddy current and hysteresis losses are the
two major core loss factors. Eddy current loss becomes
dominant in powder cores as the frequency increases.
Electromagnetic compatibility. The ability of an elect ronic
device to operate in i ts intended environment without its
performance being affected by EMI and without gener-
ating EMI that will affect other equipment.
(1) In the construction of an inductor, each turn of wire
or conductor acts as a capacitor plate. The combined
effects of each turn can be presented as a single ca-
pacitance known as the distributed capacitance. The
capacitance is in parallel with the inductor. This parallel
combination will resonate at some frequency, which is
called the self-resonant frequency (SRF). Lower distrib-
uted capacitance for a given inductance will result in a
higher SRF and vice versa.
(2) Capacitance that is not concentrated within a lumped
capacitor, but spread over a circuit or group of com-
ponents.

The corresponding parameter for the induced magnetic
field in an area perpendicular to the flux path. Flux den-
sity is determined by the field strength and permeability
of the medium in which it is measured.
A winding for toroidal cores that will result in 45% of the
core's inside diameter remaining.
Hysteresis means to lag behind. This is the tendency of
a magnetic material to retain its magnetization. Hyster-
esis causes the graph of magnetic flux density versus
magnetizing force (B-H curve) to form a loop rather than
a line. The area of the loop represents the difference
between energy stored and energy released per unit of
volume of material per cycle. This difference is called the
hysteresis loss.
A closed curve obtained for a material by plotting cor-
responding values of flux density for the ordinate and
magnetizing force for the abscissa when the material is
passing through a complete cycle between definite limits
of either magnetizing force or flux density. If the material is
not driven into saturation it is said to be on a minor loop.
Energy at integral multiples of the frequency of the fun-
damental signal. Normally expressed as THD (Total Har-
monic Distortion) but can be specified for harmonics of
interest in either a percentage of or decibels below the
power level of the fundamental frequency signal.

Impedance is expressed in ohms and is similar to the
actual resistance in a direct current circuit. In computa-
tions, impedance is handled as a complex ratio of voltage
to current. The ohm is the unit of impedance. Impedance
i s t ypi cally abbreviated as "z" or "Z". The frequency-in-
variant, real component of impedance is resistance. The
f requency-var iant , imaginary component of impedance
is reactance. The reciprocal of impedance is admittance.

The inductance rating of a core in nanoHenries per turn
squared (nH/N2) based on a peak flux density of 10
gauss (1 mT) at a frequency of 10 kHz. An AL value of 40

40mH for 1000 turns.
The product of the flux density (B) and the (de) mag-
netizing force (H) in a magnetic circuit required to reach
that flux density.
The expansion and contraction of a magnetic materi-
al with changing magnetic flux density. The saturation
magnetostriction coefficient has the symbols. It is change
of length divided by original length (a dimensionless
number) and is measured at the saturation flux density.
Magnetostriction causes audible noise if the magneto-
striction is sufficiently large and the applied field is AC
and in the audible frequency range, e.g. 50 or 60 Hz.

The Q factor or quality factor is a measure of the "qual-
ity" of a resonant system. Resonant systems respond to
frequencies close to their natural frequency much more
strongly than they respond to other frequencies. The Q
factor indicates the amount of resistance to resonance in
a system. Systems with a high Q factor resonate with a
greater amplitude (at the resonant frequency) than sys-
tems with a low Q factor. Damping decreases the Q
factor.

change of flux linkage with the coil.
A winding for a toroidal core which will result in the full
utilization of the inside circumference of the core without
the overlapping of turns. The thickness of insulation and
tightness of winding will affect results.
Skin effect is the tendency for alternating current to flow
near the surface of the conductor in lieu of flowing in a
manner as to utilize the entire crosssectional area of tile
conductor. The phenomenon causes the resistance of
the conductor to increase. The magnetic field associated
with the current in the conductor causes eddy currents
near the center of the conductor which opposes the flow
of the main current flow near the center of the conductor.
The main current flow is forced further to the surface as
the frequency of the alternating current increasing
A term used to describe how inductance responds to
changes in cur rent . Example: A 2:1 swing corresponds
to an inductor which exhibits 2 times more inductance
at very low current than it does at its maximum rated
current. This would also correspond to the core operat-
ing at 50% of initial permeability (also 50% saturation) at
maximum current.

Special Height Up/Down Core Series
We, Dongbu can supply various special height core series
depending on our customer request.
Actually, a lot of customers would like to get increasing height cores
or decreasing height cores in order to design their drawing.
It is very useful in the case of replacing two pieces core by one cores
which is the increasing height core.
As increasing height, customer can get low-cost cores and
also we can get much profit than common cores.
If you need more information on it, please feel free to contact us.
