Film capacitors

Compact X1 series with extended voltage range

TDK Corporation presents a new series of EPCOS X1 capacitors designed for an extended operating voltage of up to 530 V AC. The new capacitors are ideally suited for EMI suppression in X1 circuits (L-N). The types in the B32911* through B32918* series cover a broad capacitance range from 1 nF to 5.6 µF. In addition, they feature a compact design: Their dimensions range from 4.0 mm x 9.0 mm x 13.0 mm to 35 mm x 50 mm x 57.5 mm, depending on the capacitance, with lead spacings of between 10 mm and 52.5 mm. The types with capacitance values of 4.7 µF and 5.6 µF are equipped with 4 pins for improved mechanical stability on the PCB.

The permissible operating temperature range is from -40 °C to +110 °C. Like all EPCOS MKP capacitors, the new types also feature high rated voltages and excellent self-healing properties. The series is certified according to ENEC, UL and CSA. Typical applications include power supplies of all kinds and frequency converters.

Main applications
