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. Strip UPS Network Railway Computers Telecommunication Switching power supply Zero resistance structure: circular, has the lead, with overtemperature from institutions, epoxy resin coating Coating material: flame retardant epoxy resin, accord with UL94V-O Electrode lead: tinned copper wire Packing: in bulk TMOV - 25 D XXX - KTA (1) Zone temperature insurance tube type (2) The diameter size (3) TMOV Shape : D—Round (4) Varistor Voltage (5) Pin type
