TDK-EPC has extended its range of power factor correction (PFC) capacitors. The EPCOS PhaseCap Compact series now also comprises types for voltages from 415 V AC, 440 V AC, 480 V AC and 525 V AC. As an alternative to capacitors with dimensions of 136 mm x 200 mm (D x H), types with dimensions of 116 mm x 224 mm or 116 mm x 248 mm are now also available, depending on the reactive power that must be compensated. This means that the series covers a voltage range from 230 to 525 V AC and a capacitance range of between 3 x 27 µF and 3 x 251 µF (50 Hz). Depending on the type, they can compensate reactive powers ranging from 5 to 33 kvar. The capacitors can withstand an inrush current of up to 300 times the rated current. The components are PCB-free. Their self-healing design means that individual dielectric breakdowns do not destroy the capacitor. An integrated overpressure disconnector ensures additional safety. The capacitors are designed for a continuous operating temperature of 65°C (casing) and a service life of up to 180,000 hours.
