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.
The advantages vis-à-vis electolytic 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 for increasing the dielectric strength.
