Thermistors

Application Guide

1 – HOW TO DETERMINE THE

MAXIMUM STEADY STATE

CURRENT OF NF THERMISTORS?

• If the ambient temperature is 25°C:

the current is given in table page 30.

• If the ambient temperature is different from 25°C:

the current at 25°C must be derated as specified in the

graph below.

Example: maximum steady state current of

NF13AA0100M at 60°C ambient:

max25

x 0.9 = 3.0 A.

Derating of maximum steady state current with

ambient temperature

2 – HOW TO CALCULATE THE

WORKING TEMPERATURE OF

NF THERMISTOR?

Example: NF08AA0330M

= 0.2 A, T

ambient

= 25°C

• From the graph V (I) page 32, we find V

= 2.2 V there-

fore, R

= 11 Ω

• From the graph R(T), page 32, at R = 11 Ω, we find

T ± 65°C

3 – HOW TO CALCULATE THE

WORKING POINT OF NF

THERMISTOR AT A DIFFERENT

AMBIENT TEMPERATURE THAN

25°C?

Example: NF13AA0100M

= 3 A, T

ambient

= T

= 60°C

• R

=  (T-T

) and thus

T =



+ T

• As R

depends on T, this equation is quite complex to be

solved by an algebraic way. The quickest manner to solve

it is to operate by iterations:

for NF13,  = 16 mW/K (see page 29)

therefore, the equation becomes:

T = 562.5 R

+ 60

from the R

curve page 33 we find R

starting from T:

T (°C) R

(Ω) ➾ 562.5 R

+ 60 (°C)

185 0.28 217

190 0.26 206

195 0.24 195

200 0.22 184

The working temperature of this NF thermistor is about

195°C when operating under I

= 3 A and T

= 60°C (this

temperature is the one for which we have T = 562.5 R

60).

Important: A discrepancy may exist between practice and

theory due to the tolerance of the thermistor

(±20% usually).
