ThermoFuse® Varistors are used for overvoltage protection with an additional thermal element as safety feature.
Over the last years the fail safe functions got more popular and as a result the variety of thermally protect varistors increased on the market which resulted in many designs for different sizes and surge capabilities.
This article will show the benefits and features of TDK ThermoFuse® Varistor vs Standard Varistors.

TDK presents a new series of EPCOS power capacitors for DC link applications. The new capacitors are available for rated voltages of 700 V DC to 2000 V DC.

TDK Corporation has released tiny high-power TVS diodes for ESD protection, extending its portfolio of components for bidirectional overvoltage protection of I/O interfaces.

TDK Corporation has extended its portfolio of EPCOS ERU SMT power inductors with the ERU16 choke series, comprised of ten different types.

TDK Corporation presents a new series of EPCOS MKP-X2 capacitors for interference suppression.

TDK Corporation presents a new series of current-compensated EPCOS double-ring core chokes for the suppression of common-mode interferences.

High-performance IGBT modules switch currents in the kA range, whereby unwanted and in some cases harmful voltage overshoots can occur due to DC link leakage inductances.

TDK Corporation presents the new EPCOS aluminum electrolytic capacitor series B43548* with snap-in terminals.
