Mundorf TubeCap Capacitors

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

Technical specifications:

  • Dielectric: Polypropylene
  • Dielectric strengh: 550-1000 VDC
  • Loss factor: tan θ < 0.005 bei 1 kHz
  • Sealing compound: PU UL 94-V0
  • Useful Life: 100 000 h @ hot spot 60 degree C
  • Failure rate: 1 fit
  • Cover: 0.5 x Un ; 40 degree C
