product introduction

MF72 Power Direct Heating Negative Temperature Coefficient Thermistor

Product Description

Power type NTC suppresses the surge current at startup. Its zero-power resistance value suppresses the surge current at the moment of startup so that the surge current at the moment of startup will not be too large.

Product Features

1. Application scope:

● Conversion power supply, switching power supply,

● UPS power supply

●Electronic energy-saving lamps, ballasts and various heaters

●Various types of pictures tube and monitors Incandescent lamps, other lighting fixtures

2.Features:

● Small size, high power, strong ability to suppress surge current

● Fast response speed

● Material constant (B value) is large and residual resistance is small

● Long life and high reliability

● Complete series, wide application range

3.Installation method:

a) For use, use general soldering method for installation.

b) For vibration and impact tests, the leads are fixed, and the fixed point is 6±1mm away from the resistor body.
