Varistor
Xiamen SET electronics Co.,Ltd
It is a new patent technology in the field of surge protection. The TMOV is a fail-safe device, which integrated a disk varistor and a thermal fuse in a single package. The thermal fuse is designed to disconnect the MOV from the circuit, in case of MOV's failure. Because the MOVs might thermally run away due to the increasing leak-age current, or burn and burst in the event of a short-circuit fault.
The TMOV can offer faster response owing to its good thermo-coupling with the physical body of the MOV, comply with UL1449 3rd, IEC61643-331, IEC61051-2, GB18802.1 and ROHS compliant. The TMOV can substitute the standard MOV and provide enhanced security, never fire or burn, suitable for type 2 SPDs, Type 3 SPDs, AC Power supplies, Solar control panel and etc.
SET TMOV series have two versions: one has three lead wires with indication of MOV's failure, another has five lead wires with indication and isolated remote signal. Both versions are ROHS compliant and wave Solderable.
Key features:
● ROHS and REACH compliant
● Patent design
● UL1449 3rd certificated
● Wave solderable
● Fast response
● Compact structure
● Failure indication
● Isolated remote indication
Typical applications:
● Surge protective devices (SPD), TVSS
