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
