Shop Variable, Dual & High Voltage Capacitors on Amazon.com
Capacitors store electrical energy and are used in a variety of electrical applications. An electrical capacitor has at least two electrical conductors separated by an insulator that can store energy. Glass, film, air, and vacuum are the most commonly used insulator materials for storing a charge. There are several types of capacitors and each has its own unique characteristics. For example, a variable capacitor has rotating and stationary plates, while a power capacitor may be used as a power source and has a variety of automotive electronics applications. High voltage capacitors are used for flash photography and for lasers. Capacitors may be combined in series and in parallel. Capacitors in series can store high voltages, while capacitors in parallel can store high current. Series and parallel configurations can be combined to form large power sources and capacitors for sale may be packaged individually and in kits. When choosing capacitors, consider the environment in which it will be used and the electrical requirements of the application.
