MF74 Ultra-high Power NTC Thermistor Series
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.
●Various high-power lighting fixtures.
●Electric heaters.
2.Features:
●Reliable structure and easy installation.
●Strong ability to suppress surge current.
●The working steady-state current is large.
●Can continue to work under larger steady-state current.
3.Installation method:
a) For use, the resistor chip is installed into a cylindrical porcelain shell, and the two ends are led out with copper screw caps;
b) For vibration and impact tests, the upper and lower copper screw caps are fixed.

Why Choose us?
20+ Years Industry Experience
Founded in 2002. Four self-built factories.
The core component of all NTC temperature sensors, the high-performance temperature measuring NTC thermistor, is all produced in-house. It has a complete series and diverse structures, which can meet the precise temperature measurement in different temperature areas from low temperature to medium low temperature to medium and high temperature. These High-performance temperature measuring NTC thermistors have passed a series of safety certifications at home and abroad.
