Product Description
NTC Thermistor MF73T-1 1/40 Inrush Current Limiter 1 Ohm 40A For High-power Switching Power Supply
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.
Typical Application
* 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
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
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.
