WCAP-FTDB: Film capacitors THT DC-link boxed (MKP)

A metallized polypropylene film (MKP) is used for the new DC-Link film capacitor product series. This results in the following features and properties:

  • High ripple current load capacity
  • High dielectric strength (up to 1200 VDC)
  • High expected service life
  • Capacitance range: 1 µF - 75 µF
  • Operating temperature: -40 °C to 105 °C

DC link application

DC link application

Foil capacitors, aluminum electrolytic capacitors or MLCCs can be used for the DC link application (DC link application). The main differences include the rated voltage, the possible capacitance and the design/size of the capacitor. DC link applications include frequency converters, solar inverters and DC chargers in the field of electromobility. The diagram shows a simplified representation of a three-phase inverter.

Example applications

EV-chargers
Power factor correction (PFC) stage
UPS – uninterruptible power supplies
DC input for solar inverter
Inverter for motor drives
