Power Capacitors for DC Link and DC Filtering Applications
In case of power capacitors, TDK’s portfolio comprises different solutions for DC link and DC filter applications. We are offering a wide spectrum of capacitors with resin filled, open cases, especially designed for LV, ModCap as standard solution and MKK-DCR as a customized type. Moreover, we offer sealed cases for those applications with aggressive environmental conditions and especially strict operation requirements (current and temperature), either with oil-impregnation or with polyurethane resin as a dry option. Capacitance ranges from 3 x 200 to 3 x 3000 µF.
