Vacuum Capacitors
COMET AG has been manufacturing fixed and variable Vacuum Capacitors since 1965. Our excellent reputation for product quality has resulted in close cooperation with leading international companies in the RF industry. COMET is an expert for high vacuum technology, material science and mastering of high voltages.
COMET’s two major business areas are Semiconductor and Broadcast.
In the Semiconductor industry we supply Vacuum Capacitors for production equipment of computer chips, flat panel displays and solar cells.
In Broadcasting our Vacuum Capacitors are used primarily in short and medium wave analog and digital transmitters.
Additionally we serve also industrial, aerospace and medical application.

The design, construction and processing of COMET Vacuum Capacitors combined with decades of experience in precision manufacturing assure outstanding quality standards. The unique modular design of the capacitors allows a high degree of flexibility in production and guarantees delivery of special types on very short notice.
The superior performance and reliability of the products has been proven by hundreds of thousands of units in operation.
For performance reasons all capacitors are made with ceramic envelops, which enable the capacitors to withstand higher thermal and mechanical loads than glass. Most units fit sockets of competitive types and are electrically and mechanically compatible and interchangeable.
COMET Vacuum Capacitors are components which give excellent long lasting service, provided their specifications are carefully respected.
Today, COMET manufactures more than 500 basic types of Vacuum Capacitors, covering a wide range of applications:
- Capacitance ranges from 3 to 5000pF
- Current ratings up to 1,000 Amperes
- Voltages up to 90,000 Volts
