Handling Precautions

Safety Precautions

Ò Safety PrecautionsÓ and ÒApplication NotesÓ should be taken into consideration. For anyThe following

questions regarding the ÒHandling PrecautionsÓ, please contact our engineering section or factory.

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.)

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)

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)

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.

Under severe conditions of extreme vibration or shock.

Do not let other parts touch the Thermistors because other coating is not a generated insulator.

pending on the cleaning condition and type of cleaning solvent.

The NTC Thermistors may be damaged or deteriorated, when dropped or exposed to a large impact. Excessive

shock and impact should not be applied.

the element to the melting point of solder.

(1) When soldering the thermistor, solder for as short time as possible to minimize the exposure time of

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.

(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.

Use them within one year of manufacture and check the solderability before use.

In case of solvent cleaning, outer coating material of the NTC Thermistors may acquire the solvent, de-

In application of the Termistors, equipment should be protected against deterioration and failures of the Thermistors.
