Stabilise power converters in charging and photovoltaic systems

This makes them particularly attractive for use in AC/DC and DC/DC converters for charging systems and power electronics in e-mobility or in renewable energy solutions. The 24-model product family offers capacitance values from 1µF to 75µF.

The capacitors for stabilising DC-Link voltage are very robust. Thanks to their metallised polypropylene film design, they have self-healing properties whereby short circuits “burn out” their own cause, hence restoring an intact dielectric. Significantly more durable than other capacitor types, the WCAP-FTDB series is suitable for applications with long maintenance cycles like wind turbines. Würth Elektronik provides a boxed THT package with pitch of 27.5mm, 37.5mm and 52.5mm for this component family. The operating temperature of the film capacitors extends from -40°C to 105°C, the respective maximum voltage values attained are up to 85°C.

Like all products in the Electronic Components 2022/2023 catalogue, the WCAP-FTDB DC-Link capacitors are now available without a minimum order quantity. Würth Elektronik provides free samples and offers a wide range of characteristic measurement data of the capacitors in the REDEXPERT online tool. This facilitates the selection of suitable components.
