Compact design

The Smart-Con series delivers 45 % higher power density (compared to the Uni-Con series) in a compact, smart and patented design. This variable vacuum capacitor is able to cover an extremely wide impedance range due to a combination of high voltage, RF current and wide tuning range. Comet’s Swiss Precision Quality delivers long lifetime and the lowest cost of ownership.

Maximum power in a minimal envelope

Smart-Con capacitors are designed to optimize today’s plasma process applications: They deliver maximum power in the 10 kW class with a minimal footprint, compared to Uni-Con.

Smart-Con’s top mounting plate is on ground potential. This offers easy installation without any
additional insulation elements. Special connector flanges enable fast RF strap mounting. The high working voltage Upw allows high currents over a wide impedance range, eliminating power derating.

Smart-Con is available as a motorized and non-motorized vacuum capacitor.
