TDK EPCOS PhaseCap Energy PFC capacitors

TDK has released the EPCOS PhaseCap Energy series of high-power capacitors for power factor correction. Available with gas- or resin-filled housings, they are designed for voltages of 230 to 690 VAC and offer a reactive power of between 5 and 33 kVAr.

The life expectancy of the B25674 series of gas-impregnated capacitors is 180,000 h. The maximum permissible inrush current is 500 x IR. The maximum number of switching cycles per year is 15,000, while the maximum permissible operating temperature as per IEC 60831-1 is 60°C.

The B25675 series of resin-filled capacitors features an even longer life expectancy of 200,000 h and is likewise designed for a maximum operating temperature of 60°C and a maximum permissible inrush current of 500 x IR. Both series have increased energy density in comparison with the existing types.

The capacitors feature a diameter of between 75 and 125 mm, depending on the type, and a height of between 164 and 224 mm. They are equipped with an overpressure disconnector that isolates all three phases from the grid in the event of damage.
