TubeCap capacitors are made from a polypropylene film with special characteristics. The polypropylene film is particularly thin and self-healing. This allows the TubeCap capacitors to reach a higher maximum operating voltage with rather compact dimensions.
TubeCap has been developed to offer a high quality alternative to high voltage electrochemical capacitors and is therefore ideal for use in tube amplifiers.
Advantages of the TubeCap compared to an electrochemical capacitor:
- ESR and lower residual inductance
- Do not dry, very long life.
- Excellent self-healing properties
- Compact Case
- There is no need to connect them in series to increase the maximum permissible voltage
