Ceramic Insulator NTC Thermistor MF75-0.2/70 70A 0.2Ohm B2600 11500uF With Edge

 

Advantage of apply MF74 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.
