Vacuum trimmer capacitors

20 February 2013 Passive Components

Comet has developed a new series of vacuum capacitors with trimming functionality, meeting requirements for very accurate fixed capacitors used in VHF applications, for example antenna tuning units and match boxes.

Tuning is achieved with an Allen key and employs a self-locking system. Precise adjustment of ±5 pF is made possible with ±1,7 turns. The parts are available in capacitances between 50 and 4000 pF, with peak voltage ratings of 3 to 35 kV and maximum current handling of 27 to 164 A. Physical dimensions range from 49 to 76 mm diameter and 52 to 87 mm length.
