Description

The MF73T-1 series High Power NTC Thermistor 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.

Features

Small size, high power, reliable surge current protection.
High material constant (B value),
Low residual resistance
High steady state current, long lasting, high reliability
Convenient for PCB installation, wide operating range

Application

Can be installed into the power circuits of:
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.
