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:
● Server and communication power supplies.
● UPS and backup power systems.
● High-power LED lighting circuits.
● Industrial and commercial lighting drivers.
● Inverters.
● High-power AC/DC converter systems.
● Industrial control power supplies.
● Power tools and portable charging equipment.
● Professional high-power audio amplifiers.
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.

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. This High-performance temperature measuring NTC thermistors have passed a series of safety certifications at home and abroad.
