NTC THERMISTOR

Introduction:

NTC (Negative temperature coefficient) thermistor is a semiconductor made from

metallic oxides. It exhibits an electrical resistance that has a very predictable change

with temperature. The resistance varies significantly with temperature, more so than in

standard resistors. They are extremely sensitive to temperature change, very accurate

and interchangeable. They have a wide temperature envelope and can be hermetically

sealed for use in humid environments.

Features:

* Longevity of service, high reliability

* Small size, powerful, strong capability of surge current protection

* Instant response to surge current

* Wide operation range

* Big material constant (B value), low remain resistance.

Application:

Thermistors are widely used as

* Inrush current limiters

* Temperature sensors

* Self-resetting overcurrent protectors

* Self regulating heating elements

* Conversion power, switch mode power supply, UPS power protection

* Energy saving lights, electronic ballast filament protection

* Electronic circuit, power supply circuit protection

NTC THERMISTOR

How to select:

1. Maximum operating current > Actual operating current in the power loop

2. Rated zero power resistance at 25℃

Of which, E: loop voltage, Im: Surge current

For conversion power, reversion power, switch power, UPS power, Im = 100 times

operating current.

For filament, heater, Im = 30 times operating current.
