Passive Plus now offers a comprehensive range of high-Q variable capacitors including Air Tubular, Sapphire, Zirconia, PTFE, and Air Plate trimmers. Also known as a Trimmer Capacitor, these are designed for fine adjustments or calibration in RF Circuits, providing the ability to vary capacitance, allowing precise tuning and optimization of electronic circuits in LC filters, radio transmitters & receivers, quartz oscillators, low noise amplifiers, and NMR coil systems.
The Air Tubular trimmers have the highest adjustment precision and Q-Factor for the best electric performance; the Sapphire trimmers are the smallest in size with high thermal and mechanical stability with a capacitance from 1 to 18.5 pF and Q-Factors of 3000; the PTFE trimmers have a high working voltage of up to 2500 volt and capacitors of up to 28 pF; the largest trimmers, the Air Plates, have high adjustment accuracy and mechanical stability at extreme conditions along with a capacitance from 1 to 146 pF (select models with a capacitance of 200 pF available). The newest series of their trimmers is the Zirconia trimmers. Similar to the Sapphire trimmers, the Zirconia provide a 2.5 times higher maximum capacity.
These capacitors are available in a wide range of mounting configurations such as flange-mount, bushing mount, no lead, horizontal/vertical-mount, and screw-mount and have different sizes.
