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.
