Standardized R/T Characteristics
1 Introduction
The R/T characteristics tabulated in the following have been standardized for the resistance valueat 25 °C. The actual resistance values of a particular NTC thermistor are obtained by multiplying theratio RT/R25 (tabulated value) by the resistance value at 25 °C (specified in the data sheets).
Resistance values at intermediate temperatures within the range of the subsequent temperature in-terval can be calcuated by means of the temperature coefficient α.
α is inserted in the following equation:
RT Resistance value at temperature TRTx Resistance value at the beginning of the relevant temperature intervalTx Temperature in °C at the beginning of the relevant temperature intervalT Temperature of interest in °C (Tx < T < Tx+1)αx Temperature coefficient at temperature Tx
Example:
Given: Curve 1006R25 = 4,7 kΩα5 = 4,4
Unknown: Resistance at 7 °C (R7)
a) Calculation of the resistance value at the beginning of the relevant temperature interval(Tx = 5 °C):

2 Resistance tolerance
The tolerance range of resistance can be calculated proceeding from the rated temperature and thecorresponding rated resistance tolerance (see also chapter 3.1.3).
In practice, the following equation is used:
|∆RT/RT| Maximum spread of resistance at temperature T in %|∆RN/RN| Rated tolerance of resistance value at temperature TN (given in data sheet) in %|∆B/B| Rated tolerance of B value (given in data sheet) in %B B25/100 value (given in data sheet) in KT, TN Temperatures in K
Example:
Given: NTC B57820-M561-A5Curve 1009B25/100 = 3930B value tolerance |∆B/B| = 1,5 %Rated temperature TN = 100 °CRated resistance RN = R100 = 39,6 ΩResistance tolerance at 100 °C |∆RN/RN| = 5 %
Unknown: Resistance value at 35 °C (RT = R35)Resistance tolerance at 35 °C (|∆RT/RT| = |∆R35/R35|)
a) Calculation of reference resistance R25 (required for working with the standardized R/T curve; ifthe rated temperature is 25 °C this step is omitted) by means of equation (1):
(0,070690 = Factor of curve 1009 at 100 °C)
b) Calculation of resistance value at 35 °C:
(0,65726 = Factor of curve at 35 °C)

c) Calculation of resistance tolerance by means of equation (3):
If the R/T characteristics are computer-stored, the resistance tolerances for all temperatures canbe easily determined by an appropriate calculation program.
3 Temperature tolerance
With given resistance tolerance, the temperature tolerance is determined as follows:
α Temperature coefficient at T in %/K (see R/T characteristic)|∆RT/RT| Resistance tolerance in % at T
The following applies to the example given under point 2:
The calculation mode given here is to be regarded as an approximation of actual conditions (B valuetemperature-dependent, tolerances symmetrical); nevertheless, the results obtained are sufficientlyaccurate for practical applications.

EMI suppression capacitors
Play it safe
Whether video recorder, television,refrigerator or toaster – our EMI sup-pression capacitors do a grand job inevery possible kind of entertainmentand consumer electronics appliance.They’ve also proven their worth inswitch-mode power supplies for PCs.No wonder, because the advantagesof film technology are there to beseen: low cost, no risk of failurethrough damp, and optimum self-
healing capability. The result – lessdestruction of equipment and ensuingfires. Plus the line is safeguardedagainst surges. In this way our ca-pacitors satisfy the user’s need forsafety, and the new EMC standardstoo of course.
