The 

TubeCap

®

 is made of polyprophylene 

fi lm with special features. This is particularly 
thin and the self-healing properties are mar-
kedly 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 tech-
nical alternative to high-voltage electrolytic 
capacitors and is thus ideally suited to use in 
tube amplifi ers. 

The advantages vis-à-vis 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  

   for increasing the dielectric strength.
