TDK introduces rugged capacitors with low self inductance and high design flexibility

     TDK launches B3271*H* series of new EPCOS film capacitors. The new family of components is suitable for DC support applications with high energy and power density, with voltage ratings ranging from 500 V DC to 1600 V DC, capacitance values ranging 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 new line of capacitors is available in three lead spacing options of 27.5, 37.5 and 52.5 mm, and is offered in two - and four-pin versions, with more than 90 models and a very flexible design. To this end, TDK specially introduced the CLARA tool to help users quickly fit DC support capacitors.

     The new element 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.
