Mundorf TubeCap Film Capacitors



The Mundorf TubeCap is made of polypropylene with special features. It features a particularly thin film for better performance but due to a special coating the self-healing properties are markedly pronounced. This leads to a very high electrical strength in the capacitor with compact dimensions. The TubeCap combines a high degree of dielectric strength and low residual inductance in a very compact form of construction. It has been developed as a high-quality technical alternative to high-voltage electrolytic capacitors and is thus ideally suited to use in tube amplifiers plus of course many other applications. Great replacement for the now-defunct Black Gate capacitors.
