NTC Thermistors (Disc Type)
■ Application Notes
1. Fail-Safe Design for Equipment
In application of the Thermistors, equipment shall be
protected against deteriorations and failures of the
Thermistors.
7. Abnormal Mechanical Stress
The NTC Thermistors may be damaged or deteriorated,
when dropped or exposed to a large impact.
Excessive shock and impact shall not be applied
to the Thermistors.
2. Maximum Permissible Power
The NTC Thermistors, Disc Type shall not be operated
beyond the specified Maximum Permissible Power,
otherwise, result in failures and damages due to the
thermal run away.
8. Environmental Conditions
The NTC Thermistors shall not be operated and/or
stored under following conditions;
a) To be exposed directly to water or salt water.
b) To be exposed directly to oil, gasoline, organic
solvent and atomospheres of them.
3. Operating Temperature Range
The NTC Thermistors shall not be operated beyond
the specified Operating Temperature Range of Ð20 to
+125 ¡C.
In addition, applied power shall be derated in
accordance with the specified Derating Curve in the
Catalog.
c) Under conditions of dew formation or frost.
d) Under conditions of corrosive atomosphere such as
hydrogen sulfide, sulfurous acid, chlorine and
ammonia.
9. Plastic Molding and Potting
(Do not touch the heated part of the NTC Thermistors
by hand at large power consumption.)
In a case of plastic molding or potting, the NTC
Thermistors may be damaged or deteriorated by
extremly large mechanical stresses such as
expanding and shrinking forces caused by the heat
treatment of the plastics applied, depending on
curing conditions and type of plastics.
4. Soldering Flux
Rosin-based, non-activated flux is recommended.
5. Soldering
When soldering the NTC Thermistors, the soldering
time shall be as short as possible to minimize the
exposure time of the elements to the melting point of
solder. Take into account of the solder-heat resistance
of the product before use.
10. Mounting
,
Don t touch other parts to thermistor, because outer
coating is not for assuring insulation when mounting
the thermistor.
11. Long Term Storage
6. Post Soldering Cleaning
The NTC Thermistors shall not be stored under sever
conditions of high temperatures and high humidities.
Store them indoors under 40 ¡C max. and 75 %RH
max. Use them within one year and check the
solderability before use.
In case of solvent cleaning, outer coating material of
the thermistor may melt into the solvent, depending on
the cleaning condition and the type of cleaning solvent.
