NTC Negative Temperature CoefficientNTC
A thermistor is "a thermally sensitive resistor" that is a semiconductor whose resistance varies significantly with temperature. In
general, there are two types thermal senstive resistor. One is PTC ( Postive Temperature Coefficient); the resistance increases as
temperature increases. The other is NTC (Negative Temperature Coefficient); the resistance decreases as temperature increases.
The following description is applicable only to NTC thermistors.
-50+1000
NTC thermistor is an sensitive elements widely used in information system and control system, which is mainly used for temperature
measurements, control, protection and heating. Thermistors are thermally sensitive elements of sintered fine ceramic semiconductor
composed of several transition metal oxides, primarily Mn, Co and Ni. Their operating temperature range is from -50C to +1000C
that covers the whole range necessary for ordinary temperature control. They are also small, stable and have great sensitivity. Thanks
to these features, they are used in large quantities as temperature sensors and temperature compensation elements in consumer
electronic appliances and industrial equipment.

In order to measure temperature accurately and to control precicely, it is important to look closely at the value of of a
thermistor and minimize electric current so that measurement error caused by heating is eliminated. Thermal dissipation
constant in this catalog shows a value when a discrete element is placed in still air. Please note that values for assembled
thermal sensors will be different.
(sec.)
Thermal time constant T is a constant which indicates how fast resistance of a thermistor follows to a change in surrounding
temperature or electric current injected. The constant is expressed by a time to reach to (1-1/e) or 63.2% of a difference between
initial and final achieving temperatures of a thermistor element.
In general, B constant value ranges B25C/50C = 2,000 - 6,000K. The higher the B value is, the greater the change rate in
resistance per 1C becomes.
(mW/)
Thermal dissipation constant is a constant that expresses a degree of radiation from surface and lead wires of a thermistor element,
when electric current is applied to heat it up.
Thermal dissipation constant can be determined by the equation (3) as a ratio between a power consumption applied to a thermistor
and a degree of temperature increased by the power.

B constant B (K)
B is a constant that expresses a change rate in resistance between two temperatures, which is derived from the equation (1).
B =lnR1 - lnR2
