Power capacitors cover 365 µF to 3,900 µF range

The rated currents between 105 A and 180 A are type-conditioned, with all types designed for 5 kA recurrent pulse currents. The maximum permitted hot spot temperature is +90°C.

B25647A high-frequency power capacitors are available for rated voltages from 900 V to 1,600 V and cover a capacitance spectrum from 640 µF to 1,850 µF.

Depending on the type, the rated currents range from 160 A to 210 A with a maximum permitted hot spot temperature of +90°C.

Due to the nonconventional design, the capacitors can be fitted very close to IGBT modules, thus producing very short lead lengths. The very low self-inductance prevents voltage overshooting on the power semiconductors when the current is shut off. As a result, generally, no snubber capacitors are needed.

This design also makes parallel connections of capacitors easy.

The capacitors are qualified according to IEC 61071, IEC 61881-1, and EN 45545-2 HL3 R23 regarding fire and smoke formation and they are UL recognised.

Typical applications are compact converters for traction, renewable energies, and industrial applications.

The capacitors are available at distributor Digi-Key Electronics.
