Part Numbering

TMOV temperature tube type pressure sensitive resistor is a

kind of insurance which has the function of overtemperature

out (off) zno piezoresistor. It is in the ordinary course of MOV is

sensitive to the temperature of the chip attached device. When

power frequency current continue to increase, or MOV failure,

because of the power frequency current or MOV leakage

current increase, leading to MOV body temperature rises to the

set of TMOV action temperature, temperature sensitive device

will be disconnected. Thus cutting off the supply current of

MOV, make MOV temperature no longer increases, thus

prevent the caused due to the failure of MOV new zno

piezoresistor on fire. It USES a standard lead as a terminal,

very suitable for the PCB circuit board installation.
