TDK B3271H series capacitors
TDK announces B3271H series capacitors
TKD Corporation (TSE:6762) presents the B3271H series, new EPCOS film capacitors for DC link applications that feature high energy and power density. The capacitors are rated for voltages from 500V DC to 1600V DC, offer capacitance values from 0.47µF to 170µF and are suitable for a maximum operating temperature of up to 105°C. At a rated voltage and operating temperature of 70°C, the typical life of the rugged, self-healing and RoHS-compliant capacitors is 95,000hours.
The capacitors are available in lead spacings of 27.5mm, 37.5mm and 52.5mm, with both 2-pole and 4-pole versions. This results in more than 90 types, offering high design flexibility. For the selection of the suitable DC link capacitor TDK offers the tool CLARA.
The low self-inductances of only 11.5nH to 23nH combined with the high ripple current capability make the new capacitors particularly well suited for SiC-based inverters operating at high switching frequencies. The series is qualified to IEC 61071, AEC-Q200 as well as UL 810.
