Power NTC Thermistor
For Surge Current Suppression
MSR type Power NTC Thermistor maintains
low value of several to 50ohm as high current rather than
Thermistor for
temperaturecompensation.
The same product restrains insush
current flowing to a great volume of flat condenser in
the moment of switch-on in power commute circuit of electronics
and accordingly ,as temperature of Thermistor goer up ,resistance
get to be small .So,it makes a role of protecting a rectifier
or a great volume condenser that operation is usually slow.
