Surge Current Suppression Power NTC Thermistor 3D-9 3OHM 4A For USB Power Delivery Adapter

I Description Of The Power NTC Thermistor 3D-9 3OHM 4A

NTC or Negative Temperature Coefficient Thermistors are typically used for in-rush current limiting and

sensing applications. (As and NTC thermistor temperature increases its resistance decreses.) For in-rush

applications this attribute is used to reduce current surges to circuits thereby reducing the probability to

tripped crcuite breakers and blown fuses or damage to motors or filaments.
