This document describes the features and characteristics of the B32656S series metallized polypropylene film capacitors (MKP) produced by EPCOS AG, including high pulse strength, high contact reliability, low inductance, and climatic resilience. These capacitors are suitable for applications such as IGBT snubbering.
The B32656S series are metallized polypropylene (MKP) film capacitors designed for high‑pulse‑strength snubbering in IGBT applications. They feature a plastic case with UL‑94 V‑0 rating and epoxy resin sealing for reliable operation up to 100 °C.
The sheet lists electrical ratings (850‑2000 VDC, 450‑800 VAC), capacitance values from 47 nF to 2200 nF, tolerance codes (M ±20 %, K ±10 %, J ±5 %), strap‑type tinned‑copper terminals, and detailed dimensional drawings for each ordering code. Ordering codes combine voltage, capacitance, tolerance, and terminal type, and packaging options are provided.
