TubeCap Film Caps

The TubeCap® is made of Polypropylen film with special features. This is particularly thin and the self-healing properties are markedly pronounced due to a special coating. 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 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.

Advantages compared with electolytic capacitors:
- Lower ESR and lower residual inductivity
- No drying out; therefore longer service life
- Excellent self-healing properties
- More compact form of construction

Note on installation:
As the TubeCap® is a film capacitor, it has no polarity. Unlike electrolytic capacitors, there is no prescribed installation direction!
