Power Type ICI NTC Thermistor 5D-20 8D-20 10D-20
Description
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.

For custom specifications, or order individual replacement units, entire grids with various mounting configurations, please contact us to discuss the details.
Selection Principle
1. Maximum operating current > Actual operating current in the power loop
2 . Rated zero power resistance at 25C
of which, E: loop voltage, Im: Surge current For conversion power, reversion power, switch power, UPS power, Im=100 times operating current For filament, heater, Im =30 times operating current
