Product Features

The FH type is a model developed for high current and high frequency applications.
We have line-ups of 25 kVp, 30 kVp, and 35 kVp class peak test voltage for high withstand voltage application.
We also have a line-up of ultra-low-loss models by applying a high-alumina material for the insulation tube.
Please refer to the catalog for cautions in handling and operation and for characteristics details.

Low loss type

Dielectric loss of the ceramic insulation tube (compared with our model)

A large portion of the loss (heat dissipation) of the vacuum capacitor is a resistance loss due to the skin effect. However, the dielectric loss cannot be ignored when the frequency becomes high. The high-alumina ceramic insulation tube has less dielectric loss and it is recommended especially for high voltage applications: 40 MHz or more.
