The article covers the main types of variable capacitors, including rotor-stator capacitors and trimmer capacitors. It also discusses fixed capacitors, detailing various types such as paper capacitors, plastic film capacitors, mica capacitors, ceramic capacitors, aluminum electrolytic capacitors, and tantalum electrolytic capacitors.
Although fixed capacitors are mainstream, there are also variable capacitors, whose capacitance can be changed within a specific range. The capacitance of variable capacitors is usually altered by changing the area of opposing electrodes.
Aluminium Electrolytic Capacitors: These are the most common type of aluminium capacitors. They use an aluminium electrode with a thin oxide layer as the dielectric and a liquid or gel electrolyte.
Fixed value capacitors come in mica, ceramic, plastic, metal film, electrolytic, and more types. Let’s start by taking a look at two interesting variable capacitors. If you’re into working on old radios and other older equipment, you’ve likely run into variable capacitors that use air as the dielectric. These are also known as air core capacitors.
Their capacitance is changed with a knob or a driver. This structure for mechanically changing the capacitance makes it difficult to produce capacitors with a large capacitance. As a result, variable capacitors have a small capacitance at the pF (picofarad) level.
