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.

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

1.Power products: switch mode power supply,UPS power

2.Lighting products: incandescent lights,energy saving lights,LED lights.

3.Equipment products: industry equipment,communication equipment,electrical equipment,medical equipment

4.Home appliance: air conditioner,refrigerator,TV,washing machine

5.Instrumental products.

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.

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

1. Comply with ROHS complaint

2. Small size,big power,strong inrush current limiting ability

3. Fast response

4. Big B value,low residual resistance

5. Long life and high reliability

6. Completed series,wide operating range

7. Low cost and good stability
