Description

Introduction: NTC (negative temperature coefficient) thermistor is asemiconductor made from metallic oxides It exhibits an electrical resistance that has a verypredictable change with temperature Resistance varies significantly with temperature, more so thanin standard resistors They are extremely sensitive to temperature change, veryaccurate and interchangeable They have a wide temperature envelope and can be hermeticallysealed for use in humid environments Features: Longevity of service, high reliability Small size, powerful, strong capability of surge currentprotection 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-resting over-current protectors Self regulating heating elements Conversion power, switch mode power supply, UPS powerprotection Energy saving light, electronic ballast filamentprotection Electronic circuit, power supply circuit protection
