TDK is designed to be a rugged and durable capacitor with high flexibility

TDK's B3271*H* series of new EPCOS film capacitors. The family of components is suitable for high energy and power density DC support applications, with rated voltage ranges from 500 V DC to 1600 V DC, capacitance values from 0.47 µF to 170 µF, and operating temperatures up to 105 °C. These components are rugged, self-healing, RoHs-compliant, and have a typical life of 95,000 hours at rated voltage and 70 °C operating temperature.

The series capacitors are available in 27.5, 37.5 and 52.5 mm lead pitch options, and are available in 2-pin and 4-pin versions, with more than 90 models, making the design very flexible. To this end, TDK specially introduced the CLARA tool to help users quickly fit DC support capacitors.

The component features both low self-induction (only 11.5 nH to 23 nH) and high ripple current capabilities, making it particularly suitable for SiC based inverters operating at high switching frequencies. In addition, they comply with IEC 61071, AEC-Q200 and UL 810 standards and are suitable for a wide range of typical industrial applications, such as frequency converters, photovoltaic inverters, electric vehicle fast chargers, and automotive applications such as on-board chargers, auxiliary drives and power inverters.
