Advanced capacitor portfolio for low frequency application

October 26, 2023

With the XtraVolt Vacuum Capacitor product range, Comet meets these needs by ensuring higher voltage capability compared to standard products.

The semiconductor industry is transforming: High power density in processing modules is a requirement of many matchbox designers. With the XtraVolt low frequency Vacuum Capacitor product range Comet meets these needs with the higher voltage capability compared to standard products. This allows significant higher voltage in a compact size Vacuum Capacitor keeping the same form factor.

Advanced technology recommended for frequencies < 4 MHz


Our XtraVolt feature – recommended for frequency below 4 MHz – makes you benefit from increased power density by more than 40% in the same envelope.

RF Matching Network

Achieve more without compromising on size

XtraVolt highlights

Compact and well-designed RF Impedance Matching Network help tool builders utilize efficiently the limited space, ensuring great fab space utilization.

With XtraVolt we maximize space utilization, by offering 20 to 60% increased voltage in the same compact size of our standard Vacuum Capacitor portfolio.

Increase your RF power density by upgrading your Vacuum Capacitor to XtraVolt.
