Detailed Product Description

Large Current MF73T NTC Thermistor For Limiting Inrush Current Of High Power Switch Power

Advantage of apply MF73T NTC THERMISTOR

Best choice for limiting inrush current

Leading Technology Perfect Function Originate in domestic

Max steady state current : 120A

Inrush current is the momentary surge of current created when power is turned on to motors,transformers,power suppliers and heating elements. The more power required by industrial equipment,the larger the inrush current. It can effectively quench the inrush current by means of in series with power NTC thermistor in return circuit of power supply. The thermistor’s resistance decreases dramatically following the inrush,allowing the steady state curent to flow with very little resistance.This effect provides inrush current protection, yet allows efficiency during normal operation.The power NTC Thermistor produced by Guangdong Uchi Technology Co.,Ltd. with large scale,especially MF73T,MF73,MF74,MF75 serial products with big size,which can be applied in such inrush protection with industrial level as industrial robots and automation.

Characteristics

Small size,strong power and strong capability of surge current protection

Big material constat(B value),small remain resistance,low power consumption.

Large steady state current,long life,high reliability

Easy PCB installation,completed series,wide application range.

Recommended Application

High power switch power,Power conversion,UPS power

High power battery charger,electric vehicle battery charger

High power LED light,high power electronic energy saving lamps and other lighting lamps
