1、 Product Introduction

Power type NTC thermistor provides surge current suppression for sensitive electronic devices. Connecting a thermistor in series with a power source will limit the current surge typically generated during conduction. Once the circuit is powered on, the thermistor will quickly decrease to a very low value, with negligible power consumption and no impact on normal operating current. The use of power type NTC thermistors is the most cost-effective method to suppress surge currents and protect sensitive electronic devices from damage.

​​4、 Guide to Choosing High Power NTC Thermistors:

1. Maximum operating current>actual operating current in the power circuit

2. When the rated zero power resistor is at 25 ℃, E: circuit voltage, Im: surge current

Conversion power, inverter power supply, switching power supply, UPS power supply, Im=100 times the working current, for filament and heater, Im=30 times the working current
