Capacitors for PFC

11 May 2011 Passive Components

The range of power factor correction (PFC) capacitors available from TDK-EPC has been extended to include PhaseCap Compact models with voltages of 690, 800, 900 and 1000 V. The components of the B25673A*A* series offer PFC values of between 5 kVAR (50 Hz) and 33 kVAR (60 Hz) at capacitance values of between 3 x 11 and 3 x 55 μF. Thanks to their compact design with diameters of only 116 and 136 mm at insertion heights of 164 and 200 mm, these capacitors are particularly useful for designing space-saving PFC systems for industrial networks.

With the new types, the PhaseCap Compact series now covers 230-1000 V. Based on the proven MKK technology, these capacitors can withstand inrush currents up to 400 times their rated current. They are PCB-free and self-healing. An integrated over-pressure disconnector ensures additional safety. The capacitors are designed for a case temperature of 65°C (hot spot temperature up to 85°C) and a service life of up to 200 000 hours.
