WIMA DC-Link capacitors are ideally suited to high power converter applications where, due to increasing electrical requirements, they are commonly replacing electrolytic capacitors.
Manufactured with a low loss polypropylene dielectric, DC-Link capacitors from WIMA exhibit a higher current carrying capability as well as lower dissipation/self-heating at high frequencies when compared to electrolytic capacitors.
DC-Link capacitors from WIMA offer features that include:
- Very high capacitance/volume ratio
- High voltage rating per component
- Very low dissipation factor (ESR)
- Very high insulation resistance
- Excellent self-healing properties
- Long life expectancy
- Non-polar construction
- Particularly reliable contact configuration
- High shock and vibration resistance
- Outstanding mechanical stability
WIMA DC-LINK MKP 4 capacitors in rectangular case are available with capacitance values ranging from 5 
F through 75 F, with rated voltages from 450 VDC through 1100 VDC. For mounting purposes 4-lead versions or screwable plate options are available.
WIMA DC-LINK MKP C capacitors in cylindrical case are available with capacitances from 30 F through 250 
F, with rated voltages of 400 VDC, 600 VDC and 850 VDC. For mounting purposes axial M6 or M8 threaded terminations are available.
Based on their internal construction and their non-polarized connection configuration, WIMA DC-LINK HC capacitors can as an example, be connected as one 4500 F/400 VDC, as two 2250 F/400 VDC or alternatively as one 1125 F/800 VDC component. Depending on the case size and wiring version, values between 85 F/1600 VDC and 4500 F/400 VDC are available. Customized solutions are also supported.
