Disc Epoxy Power NTC Thermistor MF71-5D-25MY 5 ohm 12A For Inrush Current Limiting
In order to avoid inrush current when turn on the electronic circuit,power ntc thermistor often use in series circuit.Before power on, ntc thermistor in high value so it can limit inrush current,and failing to a very small degree after it.ntc thermistor's power consumption would be negligible relative to the circuit,ensuring the equipment to work.So ntc thermistor is the most simple and effective measurs in limiting inrush current,protecting electronic equipment from damage.
