(obsolet) High Power Capacitors for DC-Link & DC Filtering Applications

In case of High Power Capacitors, TDK offers different solutions for DC-Link and DC-Filter applications. We are actually offering a wide spectrum of capacitors with resin filled plus opened cases specially designed for LV, ModCap™ as standard solution and MKK-DCR as a customized one. On the other hand, we may offer sealed cases for those applications with aggressive environmental conditions and specially strict operation requirements (current and temperature), either in Oil-impregnation or in Polyurethane resin as a dry option.
