Those parameters of power NTC thermistor

Time:2021-12-26

  1. The maximum working current of the NTC thermistor is greater than the working current of the actual power loop;

  2. The nominal resistance value of the power thermistor

  R≥1.414*E/Im

  [where E is the line voltage Im is the surge current; for conversion power supply, inverter power supply, switching power supply, UPS power supply, Im=100 times the working current; for filament, heater and other circuits, Im=30 times Working current】

  3. The larger the B value, the smaller the residual resistance and the smaller the temperature rise during operation;

  4. Generally speaking, the greater the product of the time constant and the dissipation factor, the greater the thermal capacity of the resistor, the stronger the resistor's ability to suppress surge current, the maximum rated voltage and filter capacitance value, the product The maximum allowable start-up current value and the long-term operating current loaded on the NTC thermistor.
