PTC Thermistors

Product introduction

Product Introduction

PTC is a positive temperature coefficient thermistor. It is a typical semiconductor resistance with temperature sensitivity. When the temperature exceeds a certain temperature (Curie temperature), its resistance value increases with the increase of temperature.

Products Advantage
1. High ageing cofficient;
2. Small size, Superior withstanding voltage;
3. Fast reaction time;
4. High reliability,Long operating life.

Application
1. Overvoltage, overcurrent and overload protection,Mainly used for power transformers, various chargers, various instruments and other over current, overheating protection occasions;
2. Motor, compressor startup assistance;
3. Motor overheating protection, electric iron constant temperature maintenance, filament preheating delay start, LED constant current compensation.
