MF73T-1 13A 30MM Power NTC Thermistor 20% NTC Negative Temperature Coefficient

MF73T-1 10/13 High Power NTC Thermistor ICL 10 OHM 20% 13A 30MM For Battery Charger

I Description Of The MF73T-1 10/13 High Power NTC Thermistor

Power NTC Thermistor The MF73T-1 series Power NTC Thermistors provide inrush current suppression for sensitive electronics. Connecting a MF73T-1 in series with the power source will limit the current surges typically created at turn on.We mainly have two types of MF73T NTC thermsitor, namely MF73T-1 and MF73T-2.

II Application Of The MF73T-1 10/13 High Power NTC Thermistor

• High power switching power supplies, Power conversion, UPS power.
• High power battery charger, electric vehicle battery charger.
• High power LED light, high power electronic energy saving lamps and other lamps.
