Tuning capacitors are popular type of variable capacitors.

What are variable capacitors. Regular capacitors build up and store an electrical charge until its ready to use. Capacitors ship same day. To tune a radio therefore it is sometimes called a tuning capacitor or tuning condenser or as a variable reactance eg.

Short can be defeated by bending brass strip away. The main types of variable capacitors are tuning capacitors and trimmer capacitors. Alps tuning gear variable capacitor 5 gang meshed 40 720pf homebrew loop antenna tuner qrp crystal radio electronic diy project.

Mouser is an authorized distributor for many trimmer variable capacitor manufacturers including avx murata sprague goodman tusonix vishay and many more. Trimmer capacitors variable capacitors are available at mouser electronics from industry leading manufacturers. Variable capacitors have capacitance values that can be varied by applying voltage to their electrodes.

A variable capacitor is a special type of capacitor most commonly used for tuning radios which allows the amount of electrical charge it can hold to be altered over a certain range measured in a unit known as farads. For impedance matching in antenna tuners. There are many uses of these variable resistors such as for tuning in lc circuits of radio receivers for impedance matching in antennas etc.
