Latest company news about Inrush Current Limiter MF73T Introduction

Inrush Current Limiter can suppress surge currents in circuits. And after completing the function of suppressing the surge current, the resistance value of the NTC thermistor will drop to a very small level by utilizing the continuous action of the current.

 

High Power NTC Thermistor MF73T Series

Product Description

Power type NTC suppresses the surge current at startup. Its zero power resistance value suppresses the surge current at the moment of startup so that the surge current at the moment of startup will not be too large.

Product Features

1. Application scope:

●High-power switching power supply, conversion power supply, UPS power supply

●High-power power battery charger, electric vehicle charger

●High-power LED lights, high-power electronic energy-saving lamps and other lighting fixtures

 

2.Features:

● Small size, high power, strong ability to suppress surge current

●The material constant (B value) is large, the residual resistance is small, and its own power consumption is small

●High current, long life, high reliability

●Easy for circuit board installation, complete series, wide application range

 

3.Installation method:

a) For use, use general soldering method for installation;

b) For vibration and impact tests, the leads are fixed and the fixed point is 6±1mm away from the resistor body.
