Capacitors stabilise power converters in PV systems
A series of film capacitors by Würth Elektronik is designed for DC-Link applications The WCAP-FTDB DC-Link capacitors can operate from 500 to 1200V and are characterised by high ripple current capability. This makes them suitable 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 1.0 to 75 microF. The capacitors are robust with a metallised polypropylene film design exhibiting self-healing properties whereby short circuits “burn out” their own cause and restore an intact dielectric. They are more durable than other capacitor types, said Würth Elektronik and are suitable for applications with long maintenance cycles, such as wind turbines.
Würth Elektronik provides a boxed through hole package with pitch of 27.5 x 37.5 x 52.5 mm for this component family. The operating temperature of the film capacitors extends from -40 to +105 degrees C. The respective maximum voltage values attained are up to 85 degrees C.
The WCAP-FTDB DC-Link capacitors are available now 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 to help customers select suitable components.
