TDK Corporation introduces the xEVCap, a standardized and modular DC link capacitor design for powertrain inverters in passenger cars, commercial and off-highway vehicles, and machinery tools. Typically, such capacitor designs are fully customized, making the development time-consuming and practical only in large production volumes. In addition, if the customer requirements change during the project, this can further increase the time required for capacitor development and thus delay the overall project.

TDK Corporation (TSE:6762) presents a new series of EPCOS power capacitors for DC link applications designed for an operating temperature of up to +105 °C. The components with the ordering code B25695E can operate at rated DC voltages from 700 V to 1300 V (voltage derating necessary from +85 °C). The ESR ranges from 1.0 mΩ to 2.7 mΩ, resulting in a current capability of up to 110 A at +70 °C, depending on the model (current derating necessary at higher temperatures). However, the film capacitors can repetitively withstand current peaks of up to 15.8 kA. At the rated voltage and +75 °C, their service life is 120,000 h – up to 35% more than the standard version

TDK Corporation (TSE: 6762) presents ModCapTM HF, a modular capacitor concept for DC link applications that is able to work at very high switching frequencies. The six newly developed power capacitors of the B25647A* series are available for rated voltages from 900 V to 1600 V and cover a capacitance spectrum from 640 µF to 1850 µF. Depending on the type, the rated currents range from 160 A to 210 A with a maximum permitted hot spot temperature of 90 °C.
