Mundorf Tubecap capacitors

The TubeCap® is made of polypropylene film with several special features. The composite film is incredibly thin with superb self-healing properties these features are markedly pronounced due to a special coating used. This gives a very high electrical strength in a capacitor with such compact dimensions.

The TubeCap® combines a high degree of dielectric strength and low residual inductivity with 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 power supplies.

The advantages over electrolytic capacitors are:

  • Lower ESR and lower residual inductivity
  • No drying out; therefore longer service life
  • Excellent Self-healing properties
  • More compact form of construction
  • There is no series connection necessary
