Two series of EPCOS X1 capacitors designed for an extended operating voltage of up to 530VAC have been introduced by TDK. The B32911 and B32918 series' are particularly suitable for EMI suppression in X1 circuits (L-N).
The devices cover a broad capacitance range from 1nF to 5.6µF. In addition, the capacitors feature a compact design, with dimensions ranging from 4.0x9.0x13.0mm to 35x50x57.5mm, depending on the capacitance, with lead spacings of between 10 and 52.5mm. The types with capacitance values of 4.7µF and 5.6µF are equipped with four pins for improved mechanical stability on the PCB.
The permissible operating temperature range is from -40 to +110°C. Like all EPCOS MKP capacitors, the new types also feature high rated voltages and outstanding self-healing properties. The series are certified according to ENEC, UL and CSA. Typical applications include power supplies of all kinds and frequency converters.
