Disc Type NTC Thermistors
Handling Precautions
Safety Precautions
The Disc Type NTC Thermisters (hereafter referred to as ÒThe NTC ThermistorsÓ) may fail in burnout, flaming or
glowing in the worst case, when subjected to severe conditions of electrical, environmental and/or
mechanical stresses.
The following Ò Safety PrecautionsÓ and ÒApplication NotesÓ should be taken into consideration. For any
questions regarding the ÒHandling PrecautionsÓ, please contact our engineering section or factory.
1.
Precautions for Safety
1.1 Operating Power
The NTC Thermistors should not be operated beyond their specified Maximum Permissible Power in the Catalog or
the Individual Specifications, otherwise , burnout or damages due to the thermal run awa could result. (if operated in
ambient temperature above 25 ¡C, power rating should be derated in accordance with the derating curve.)
1.2 Operating Temperature Range
The NTC Thermistors should not be operated beyond their specified Operating Temperature Range of in
the Catalog or the Individual Specifications.
(Do not touch the heated part of the NTC Themistors by hand during operation)
1.3 Plastic Molding and Potting
In case of plastic molding or potting, the NTC Thermistors may be damaged or deteriorated by extreme
mechanical stresses such as expanding and shrinking forces caused by the heat treatment of the plastics
applied (depending on curing conditions and types of plastics)
1.4 Environmental Conditions
The NTC Thermistors should not be operated and/or stored under the following environmental conditions;
a) Direct exposure to water or drops of water.
b) Direct exposure to sunlight.
c) Under conditions of high humidity or water condensation.
d) Direct exposure to oil, gasoline or organic solvent and/or atomospheres of them.
e) Under conditions of deoxidized or corrosive atomospheres such as chlorine, hydrogen sulfide, sulfur oxide
or vinyl chloride.
f) Under severe conditions of extreme vibration or shock.
1.5 Mounting
Do not let other parts touch the Thermistors because other coating is not a generated insulator.
1.6 Fail-Safe Design for Equipment
In application of the Termistors, equipment should be protected against deterioration and failures of the Thermistors.
2. Application Notes
2.1 Soldering Flux
Rosin-based and non-activated type soldering flux is recommended.
2.2 Post Soldering Cleaning
In case of solvent cleaning, outer coating material of the NTC Thermistors may acquire the solvent, depending on the cleaning condition and type of cleaning solvent.
2.3 Abnormal Mechanical Stresses
The NTC Thermistors may be damaged or deteriorated, when dropped or exposed to a large impact. Excessive
shock and impact should not be applied.
2.4 Soldering
(1) When soldering the thermistor, solder for as short time as possible to minimize the exposure time of
the element to the melting point of solder.
Take into account the solder-heat resistance of the product before use.
(2) In soldering the device, the body and outer coating section should not be touched by molten solder
and/or heated iron tip.
2.5 Long Term Storage
(1) NTC Thermistors should not be stored under severe conditions of high temperature and/or high humidity.
(2) NTC Thermistors should not be stored under conditions of corrosive atomospheres such as hydrogen
sulfide, sulfur oxide, chlorine, and ammonia etc.
(3) NTC Thermistors should not be exposed to direct sunlight.
(4) NTC Thermistors should not be stored under conditions of condensation.
(5) Store them indoors under 40 ¡C max. and 75 %RH max.
Use them within one year of manufacture and check the solderability before use.
