20mm Power NTC Thermistor 3D-20 3ohm 8A Surge

NTC thermistor

1.Resin coated disk thermistor

2.Suitable for AC and DC circuits

3.Fast response to surge current


20mm Power NTC Thermistor

MF72-3D20, Negative Temperature Coefficient (NTC) Thermistor, 3ohms, 20%, 8A Max. steady-state current, Inrush current limiting thermistor, 20mm diameter.

The MF72 Power NTC Thermistors provide inrush current suppression for sensitive electronics. Connecting a MF72 power ntc thermistor 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 power ntc thermistor 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.
