Negative Temperature Coefficient NTC Thermistor Inrush Current Limiting 5D-5 5R 1A

Negative Temperature Coefficient NTC Thermistor Inrush Current Limiting 5D-5 5R 1A

Operating Principle Of The NTC Thermistor Inrush Current Limiting 5D-5 5R 1A

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.

Selection Guide Of The NTC Thermistor Inrush Current Limiting 5D-5 5R 1A

1. Max operating current of ntc thermistor Imax > actual operating current in power circuit.

2. Rated resistance of ntc thermistor R25≥(root of 2)xE/Im

E: Line voltage  Im: Max inrush current current in circuit

3. B value is bigger, residual resistance is smaller, temperature rising is smaller when operating.
