This document describes the features and characteristics of the B32656S series metallized polypropylene film capacitors produced by EPCOS AG. These capacitors have high pulse strength and high contact reliability, stable capacitance value, and are suitable for applications such as IGBT snubbering. The capacitors are constructed with polypropylene film dielectric and wound capacitor technology with internal series connection. They have a plastic case with good sealing properties and strap terminals made of tinned copper with low inductance. The B32656S series offers a range of options with wide rated voltage range.
The B32656S series are metallized polypropylene (MKP) film capacitors designed for IGBT snubbering and other high‑pulse‑strength applications. They feature a plastic case with epoxy resin sealing and strap terminals for reliable mounting.
Key data include rated voltages from 850 VDC to 2000 VDC, capacitance values from 47 nF up to 2200 nF, a maximum operating temperature of +100 °C, and compact dimensions such as 12.0 × 22.5 × 42.0 mm. Electrical parameters like ESR, insulation resistance, and pulse handling capability are also detailed.
