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.
