Capacitors have many uses in electronic and electrical systems. They are so ubiquitous that it is rare that an electrical product does not include at least one for some purpose. Capacitors allow only AC signals to pass when they are charged blocking DC signals. The main components of filters are capacitors. Capacitors have the ability to ...
The physical form and construction of practical capacitors vary widely and many types of capacitor are in common use. Most capacitors contain at least two electrical conductors, often in the form of metallic plates or surfaces separated by a dielectric medium. A conductor may be a foil, thin film, sintered bead of metal, or an electrolyte. The ...
The tests and requirements to be met by capacitors for use in electronic equipment for approval as standardized types are set out in the generic specification IEC/EN 60384–1 in the following sections. [74] Generic specification. IEC/EN 60384-1 - Fixed capacitors for use in electronic equipment; Ceramic capacitors
power electronic capacitor A power capacitor intended to be used in power electronic equipment and capable of operating continuously under non-sinusoidal current or voltage. power electronics The field of electronics which deals with the conversion or switching of electric power with or without control of that power. principal arm
Aluminium electrolytic capacitors form the bulk of the electrolytic capacitors used in electronics because of the large diversity of sizes and the inexpensive production. Tantalum electrolytic capacitors, usually used in the SMD (surface-mount device) version, have a higher specific capacitance than the aluminium electrolytic capacitors and are ...
A microscope image of an integrated circuit die used to control LCDs.The pinouts are the dark circles surrounding the integrated circuit.. An integrated circuit (IC), also known as a microchip or simply chip, is a set of electronic circuits, consisting of various electronic components (such as transistors, resistors, and capacitors) and their interconnections.

Analog electronic circuits are those in which current or voltage may vary continuously with time to correspond to the information being represented. A simple schematic showing wires, a resistor, and a battery. The basic components of analog circuits are wires, resistors, capacitors, inductors, diodes, and transistors.
The capacitance of the majority of capacitors used in electronic circuits is generally several orders of magnitude smaller than the farad. The most common units of capacitance are the microfarad (μF), nanofarad (nF), picofarad (pF), and, in microcircuits, femtofarad (fF).
