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:
ISSmax25 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
ISS = 0.2 A, Tambient = 25°C
From the graph V (I) page 32, we find VSS = 2.2 V there-
fore, RSS = 11
From the graph R(T), page 32, at R = 11 , 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
ISS = 3 A, Tambient = TA= 60°C
RTISS2= (T-TA) and thus
RTISS2
T = + TA
• As RTdepends 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 RT+ 60
from the RTcurve page 33 we find RTstarting from T:
T (°C) RT()562.5 RT+ 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 ISS = 3 A and TA= 60°C (this
temperature is the one for which we have T = 562.5 RT+
60).
Important: A discrepancy may exist between practice and
theory due to the tolerance of the thermistor
(±20% usually).
