TDK Launches Rugged Capacitors with Low Self-Inductance and High Design Flexibility
TDK Corporation presents the B3271*H* series of new EPCOS film capacitors. The new series of components are suitable for DC support applications with high energy and power density, with rated voltages ranging from 500 V DC to 1600 V DC, capacitance values ranging from 0.47 µF to 170 µF, and a maximum operating temperature of 105 °C. The components are rugged, self-healing, RoHS compliant, and have a typical lifetime of 95,000 hours at rated voltage and 70°C operating temperature.
The new series of capacitors are available in three lead spacings of 27.5, 37.5 and 52.5 mm, and are available in 2-pin and 4-pin versions. With more than 90 models, the design is very flexible. To this end, TDK has specially launched the CLARA tool to help users quickly and properly select DC support capacitors.
Combining low self-inductance (only 11.5 nH to 23 nH) and high ripple current capability, the new components are particularly suitable for SiC-based inverters operating at high switching frequencies. In addition, they are compliant with IEC 61071, AEC-Q200 and UL 810 standards, making them suitable for a wide range of typical industrial applications such as frequency converters, photovoltaic inverters, fast chargers for electric vehicles, as well as on-board chargers, auxiliary drives and power inverters devices and other automotive applications.
