DC link capacitors rated for continuous operation up to +125 °C

February 11, 2026 By Puja Mitra Leave a Comment

The B3271xP series from TDK Corporation is a range of DC link film capacitors rated for operating temperatures up to +125 °C with no power derating to +105 °C, designed for automotive and industrial power electronics such as xEV traction inverters, onboard chargers, DC-DC converters and solar inverters. The series offers capacitance values from 0.47 µF to 110 µF and rated voltages from 600 V to 1200 V, using a polypropylene (MKP) dielectric to support low ESR, high ripple current capability and self-healing performance under continuous electrical stress. Available in 2-pin and optional 4-pin configurations with AEC-Q200E compliance and UL 810 construction, the capacitors support stable DC link filtering and thermal management in compact converter designs.
