Würth Elektronik introduces its WCAP-FTXH capacitor series

All articles in this series are ENEC 10, cULus, and CQC certified and belong to the X2 safety class capacitors according to IEC 60384-14. What makes the capacitors – designed for 310V rated voltage – particularly special is their resistance to heat and moisture. They therefore pass a 1000-hour test at 85°C and 85% relative humidity with the rated voltage applied.

Their operating temperature range extends from -40 to +110°C. The WCAP-FTXH family of capacitors has self-healing properties thanks to its polypropylene dielectric: If a short circuit occurs in the component, it leads to the elimination of its own cause by vaporising the defect, thus restoring an intact dielectric. The film capacitors are available in 21 variants with different capacitance values (from 33nF to 10µF), voltage ramp-up rates, and insulation resistances.

The components have different sizes depending on their values, and a pin pitch from 15mm to 37.5mm.
