MF72
Power NTC Thermistor
MF72
Power NTC Thermistor. The MF72 series Power
NTC Thermistors provide inrush current suppression for
sensitive electronics. Connecting a MF72 in series with the
power source will limit the current surges typically created
at turn on. Once the circuit is energized the resistance of
the MF72 will decrease rapidly to a very low value, power
consumption can be ignored and there will be no effect on
normal operating current. Using the MF72 Power NTC
Thermistor is a most cost-effective way to curb surge
current and protect sensitive electronics from damage.
