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

The installed capacity of renewable energies has been increasing exponentially in the last decades. In the coming years the development of new projects will be accelerated driven by global warming and independence from fossil energies.
Wind power and photovoltaic systems are based on powerful AC-DC and DC-AC converters. They require reliable power capacitors for AC filtering and voltage stabilization in the DC link circuits. TDK offers a complete portfolio of power capacitors customized for these issues with a wide range of voltages and capacitances.
