Project Description

▋ MF72 NTC Thermistor Introduction

In order to avoid the inrush current generated in the electronic circuit at the moment of power-on, a power type NTC thermistor is connected in series in the power supply circuit, which can effectively suppress the inrush current at the time of starting, and after the suppression of the surge current is completed, Due to the continuous action of its current, the resistance value of the power type NTC thermistor will drop to a very small extent, and the power consumed by it will be negligible and will not affect the normal operating current. Therefore, the use of power-type NTC thermistors in the power supply circuit is the easiest and most effective measure to suppress surges during startup to protect electronic equipment from damage.
