TDK Corporation has introduced two new series of PhaseCap® Energy Plus EPCOS PFC capacitors. First in the lineup is the B25674C* Series, which is gas-impregnated and covers a voltage range from AC 230 to 690V. It offers compensation ratings from 5 to 33.1kvar, depending on the type. Additionally, the B25675C* Series capacitor is impregnated with a biodegradable resin. It is rated for voltages from AC230 to 1000V, with compensation ratings of up to 60kvar.

Unparalleled Lifetime of 240,000 Hours

These series feature an unrivaled lifetime of up to 240,000 hours in temperature class -40/D, class IP20 touch-proof terminals, and pre-mounted ceramic-based discharge resistors. They offer up to 15,000 switching operations per year. This rating is double the amount of previous types. Meanwhile, for short periods, the series can be operated at a temperature of 60°C, with hotspot temperatures of up to 85°C permissible.

Higher Inrush Current

The capacitors features a robust winding design with wave-cutting technology. This allows the capacitors to be subjected to inrush currents equivalent to 500 times the rated current. Moreover, the PhaseCap Energy Plus types are self-healing and CE and UL certified. In the event of an overload, all three phases are disconnected from the mains via an internal overpressure disconnector. The capacitors feature class IP20 touch-proof terminals. Further, they have pre-mounted ceramic-based discharge resistors.

Application Fields

The robust components are suitable for automatic PFC systems, capacitor banks, individual and group compensation, fixed and switched compensation systems as well as dynamic PFC systems.
