Chip thermistors are high quality and low cost devices
especially developed for surface mounting applications. They
are widely used for temperature compensation but can also
achieve temperature control of printed circuits.
A nickel barrier metallization provides outstanding qualities of
solderability and enables this chip to meet the requirements
of the most severe soldering processes.

Chip thermistors are a high quality and low cost device espe-
cially developed for surface mounting applications. They are
widely used for temperature compensation but can also
achieve temperature control of printed circuits. Its silver -
palladium - platinum metallization provides a high degree of
resistance to dewetting of the terminations during soldering
(typically 260°C / 30 s).

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 27.
• 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 29, we find VSS = 2.2 V there-
fore, RSS = 11 Ω
• From the graph R(T), page 29, 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
ISS = 3 A, Tambient = TA= 60°C
•RTISS2= d(T-TA) and thus
RTISS2
T = d+ 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, d = 16 mW/K (see page 26)
therefore, the equation becomes:
T = 562.5 RT+ 60
from the RTcurve page 30 we find RTstarting from T:
T (°C) RT(Ω)➾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).

DESIGN OF THE THERMISTOR
Choice of the resistances
If the application is to measure the temperature around a
defined point, a unique nominal resistance can be chosen
(for example, among standard values of the ND range prod-
ucts presented on pages 16 to 21).
When it is requir ed to measure the temperature over selected
ranges T1–T2, T2–T3, ..., the corresponding resistance
R1, R2, R3, ..., must be such that they can be located
on the R (T) characteristic of an existing NTC material
(for example among standard materials whose R (T) are
displayed on pages 32 to 35).
The resistances must also be compatible with the resistivity
of the material and the dimensions of the thermistor.
Choice of the tolerances
The precision of the temperature measurement determines
the calculation of the tolerance on the resistance:
DR/R = a(%/°C). DT (°C)
For example, the NTC NR55--3049-99, using “N5” material
(R (T) characteristic displayed on page 34), requires a preci-
sion of 1°C over the temperature range 110°C - 120°C.
The tolerances can be calculated:
DR110°C /R110°C = 1°C* 2.91%/°C = 2.91%
DR120°C /R120°C = 1°C* 2.76%/°C = 2.76%

P/N Code
This type of product is widely used in automotive and
consumer applications.
They are assembled in custom-probes for sensing the
temperature of liquids (water, oil, ...), gases or surface of any
other component.
The metallization covers completely the surfaces of the
thermistor.
The particularly flat and smooth surfaces ensure an excellent
electrical and thermal contact under pressure.
