High-speed drive system for
ultra-long life Vacuum Capacitors

Increase the reliability and useful lifetime of your Impedance Matching Network with the best Vacuum Capacitors along with the latest drive system technology.

The expected lifetime of a Vacuum Capacitor is determined by the drive system and bellow design. Comet’s field proven bellow has been recognized as the leading design for RF stability and lifetime. With the introduction of Ultra Life, the drive system components now last at least three times longer.

The lifetime of Vacuum Capacitors – which are the critical parts of Impedance Matching Networks – is mainly determined by time-to-failure of its moving parts, the bellows and drive systems. Comet has continually improved its capacitors over many years to meet and answer the formidable challenging requirements of the semiconductor industry.

Drive system components
last at least

3 x longer

Benefits

  • Designed for 600 and 1200 RPM for fast match tuning
  • Lifetime up to 100 million turns
  • RoHS compliant
  • Available for most Comet Vacuum Capacitors
  • Customized types available

Avoid system breakdowns

Friction in the drive system may cause particle formations, increased torque, leading to sticktion and finally result in failure. Comet Ultra Life drive systems enhance the lifespan of Vacuum Capacitor and therefore, Impedance Matching Networks, by at least threefold compared to current products. Comet improvements ensure trouble free operation and lifetime up to 100 million turns.
