- Big material constant (B value), small remain resistance
- Longevity of service, high reliability
- Integral series, extensive operating range
Introduction:
- When you turn on an electrical equipment, surge current can be restrained by a power NTC thermistor connected in series with the power circuit
- Because of the continuing action of current, temperature of power NTC thermistor raising, the resistance will rapidly drop to a small value, the consumed power can be ignored
- So it can't affect normal operating current
- Therefore, using power NTC thermistor is a most effectively and most brief measure to restrain surge current, protecting electrical, equipment from destruction
