The EPCOS DC link capacitor is designed for Infineon’s HybridPACK™ 1-DC6 IGBT module. Source: TDK
The capacitor with the order number B25655P4607J021 is designed for a rated voltage of 450 V DC and offers a capacitance of 600 µF. Its current capability is about 150 A at a maximum ambient temperature of 105° C and a cooled temperature on the underside of 75° C. The component is designed using power capacitor chip technology in which the capacitor element is constructed as a stacked winding, with which a volume fill factor of nearly one is achieved. The housing measures a compact 140 mm x 72 mm x 50 mm.
Furthermore a flat, winding version is offered in the same housing (B25655P4477J121). This type has a capacitance of 470 µF and is likewise designed for 450 V DC. At a maximum ambient temperature of 105° C and a cooled temperature on the underside of 75° C, its current capability is about 150 A. The ESR value of this design is 0.8 mΩ, and the ESL value is 25 nH.
Apart from the standard version, the capacitor is also available with an additional connection for the EPCOS high-voltage DC EMC filter. All in all, the combination of the IGBT module with the link circuit capacitor enables the design of extremely compact inverters for xEV applications or for use as industrial inverters.
