TDK ThermoFuse™ Varistors

TDK ThermoFuse™ Varistors feature a wide operating voltage range of 130VRMS to 750VRMS. These varistors are self-protected under abnormal overvoltage conditions and offer high-energy Advanced series E2. TDK ThermoFuse varistors include either leaded square varistor elements or leaded round varistor elements. These varistors are made of epoxy molding and are flame-retardant as per UL 94 V-0. The ThermoFuse varistors come with tinned copper wire and metal compound wire terminals. Typical applications include power meters, telecom, transient voltage surger suppressors (TVSS), and household appliances.

The MT25 series currently covers a voltage range from 150VRMS to 385VRMS. These varistors feature a 20kA maximum surge current capability at a pulse form of 8/20µs according to IEC 61643-11.

The MT30 Series includes types that are designed for voltages from 150VRMS to 750VRMS. These varistors feature 25kA maximum surge current capability at a pulse form of 8/20µs according to IEC 61643-11.
