6.8 ohm 20mm Diameter 6.8D-20 Inrush Current Limiting NTC
Thermistor
Features of MF72 Power Type NTC Thermistor
1.MF72 series is radial lead resin coating type
2.Small size, large power and strong ability to suppress surge
current
3.Quick response
4.The material constant(B value) is large and the residual
resistance issmall
5.Long life and high reliability
6.Completed product specifications and wide scope of work
7.Working temperature:-55+200 degrees elsius
Selection Principle of Power Type NTC Thermistor
1. Maximum working current of a thermal resistor> The working
current of the actual power circuit
2. The nominal resistance value of thermistor
E: line voltage Im: inrush current
For switch power,Inverter current, usb power lm=100times working
current
Applications of Inrush Current Limiting NTC Thermistor
◎Coversion power-supply, switch power, ups power
◎Electronic energy saving lamps, electronic ballast and all kinds
of electric heater
◎All kinds of RT, display
◎Bulb and other lighting lamps
