Metal-paper capacitors are a special type of film capacitors and are mainly used as interference suppression capacitors. Metal-paper capacitors are particularly robust and, like all film capacitors, have self-healing properties. The advantage of metal-paper capacitors is their robustness with regard to active and passive flammability, their comparatively good sealing against moisture and their excellent regeneration behavior. Worldwide, there are only a few manufacturers of this capacitor technology still available from Beckmann Elektronik.
