The engineer''s guide to air variable capacitors

What is an air variable capacitor? Air variable capacitors are also called variable capacitors, adjustable capacitors and tuning capacitors. The plates form half circles with one set of stationary plates and another set that rotates

The engineer''s guide to air variable capacitors

Other variable capacitor types exist, such as variable glass capacitors for high-temperature applications with a high Q; trimmer capacitors with plastic dielectrics with much lower RMS voltage, current ratings and Q

Capacitors | Trimmers, Variable Capacitors | DigiKey

Trimmer and variable capacitors are a group of devices that provide a capacitance that is user-adjustable within some specified, relatively narrow range. Devices covering capacitance ranges of a few picofarads to a few nanofarads

What is capacitor in physics?

These are the most common type of capacitor and have a fixed capacitance value. • Discrete fixed capacitors: Individual components with a specific capacitance value, such as a 100 nF or 220 μF capacitor. • Chip capacitors: Small, integrated capacitors used in integrated circuits and surface-mount technologies. Variable Capacitors

Variable capacitor

OverviewElectronically controlled capacitanceMechanically controlled capacitanceSpecial forms of mechanically variable capacitorsHistoryTransducersNotesExternal links

The thickness of the depletion layer of a reverse-biased semiconductor diode varies with the DC voltage applied across the diode. Any diode exhibits this effect (including p/n junctions in transistors), but devices specifically sold as variable capacitance diodes (also called varactors or varicaps) are designed with a large junction area and a doping profile specifically designed to maximize capacitance.
