  2. Electrolytic capacitor - Wikipedia

    en.wikipedia.org/wiki/Electrolytic_capacitor

    An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization.This oxide layer acts as the dielectric of the capacitor.

  3. Aluminum electrolytic capacitor - Wikipedia

    en.wikipedia.org/.../Aluminum_electrolytic_capacitor

    Aluminum capacitors with liquid electrolytes based on borax or organic solvents have a large range of types and ratings. Capacitors with water-based electrolytes are often found in digital devices for mass production. Types with solid manganese dioxide electrolyte have served in the past as a "tantalum replacement".

  4. Applications of capacitors - Wikipedia

    en.wikipedia.org/wiki/Applications_of_capacitors

    Capacitors used for suppressing undesirable frequencies are sometimes called filter capacitors. They are common in electrical and electronic equipment, and cover a number of applications, such as: Glitch removal on direct current (DC) power rails; Radio frequency interference (RFI) removal for signal or power lines entering or leaving equipment

  5. Ceramic capacitor - Wikipedia

    en.wikipedia.org/wiki/Ceramic_capacitor

    A typical ceramic through-hole capacitor. A ceramic capacitor is a fixed-value capacitor where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications.

  6. Charge pump - Wikipedia

    en.wikipedia.org/wiki/Charge_pump

    Two-stage charge pump with DC voltage supply and a pump control signal S 0 Dickson charge pump with diodes Dickson charge pump with MOSFETs PLL charge pump. A charge pump is a kind of DC-to-DC converter that uses capacitors for energetic charge storage to raise or lower voltage.

  7. SAL electrolytic capacitor - Wikipedia

    en.wikipedia.org/wiki/SAL_electrolytic_capacitor

    SAL electrolytic capacitors (SAL meaning solid aluminum) are a form of capacitor developed for high capacitance in a small package, with a long and robust service life. They are aluminum electrolytic capacitors with anodic oxidized aluminum oxide as dielectric and with the semiconducting solid manganese dioxide as electrolyte. They are made of ...

  8. Motor capacitor - Wikipedia

    en.wikipedia.org/wiki/Motor_capacitor

    A typical motor start capacitor. A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run ...

  9. Capacitor - Wikipedia

    en.wikipedia.org/wiki/Capacitor

    In the short-time limit, if the capacitor starts with a certain voltage V, since the voltage drop on the capacitor is known at this instant, we can replace it with an ideal voltage source of voltage V.
