MF73 High-power NTC Thermistor Introduction

High Power NTC Thermistor Characteristic

◎  Reliable Configuration and convenient installment

◎  Have the strongest capability of surge current protection and energy absorption

◎  Maximum steady state operating current

◎  Longevity of service,high reliability

High Power NTC Thermistor Application

All kinds of power supply,UPS power supply,Switching power supply

EV charger,charging pile

Motor driver,superpower server motor driver,logic controller

High power plasma electric welder,cutting machine,super power lightning lamp

Nuclear managetic resonance equipment,super power audio power amplifier,high circle transformer

The solar panel arrays with high capacity power inverter

The industrial robot drived by high voltage power supply, intelligent electric cabinet with low voltage.

High Power NTC Thermistor Key Benefits:

Recognized By Underwriters Laboratories For Ensured Safety

Designed To Withstand High Steady Sate Current

Absorbs And Minimizes High Input Energy

Cost Effective One Component Solution To Inrush Current

Wide Temperature Range Of Operation

 

High-Power NTC Thermistors are used to reduce the inrush current that occurs when an electrical device is switched on. High inrush current is the result of the maximum instantaneous input current drawn by an electrical device during the initial power up. As technology continues to advance, most systems today run efficiently and maintain a low impedance which in turn contributes to high inrush current.

Additionally, devices that produce alternating current such as electric motors or transformers can draw several times their steady state current at switch on. Although this additional draw of inrush often lasts less than ½ of a normal 60 hertz cycle, that is enough time to cause possible damage to the equipment.
