  2. Capacitor types - Wikipedia

    en.wikipedia.org/wiki/Capacitor_types

    The change of capacitance for P 100 and N 470 Class 1 ceramic capacitors is lower than 1%, for capacitors with N 750 to N 1500 ceramics it is ≤ 2%. Film capacitors may lose capacitance due to self-healing processes or gain it due to humidity influences.

  3. Capacitance - Wikipedia

    en.wikipedia.org/wiki/Capacitance

    The SI unit of capacitance is the farad (symbol: F), named after the English physicist Michael Faraday. [2] A 1 farad capacitor, when charged with 1 coulomb of electrical charge, has a potential difference of 1 volt between its plates. [3] The reciprocal of capacitance is called elastance.

  4. Farad - Wikipedia

    en.wikipedia.org/wiki/Farad

    The statfarad (abbreviated statF) is a rarely used CGS unit equivalent to the capacitance of a capacitor with a charge of 1 statcoulomb across a potential difference of 1 statvolt. It is 1/(10 −5 c 2) farad, approximately 1.1126 picofarads. More commonly, the centimeter (cm) is used, which is equal to the statfarad.

  5. Capacitor - Wikipedia

    en.wikipedia.org/wiki/Capacitor

    In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone.

  6. Ceramic capacitor - Wikipedia

    en.wikipedia.org/wiki/Ceramic_capacitor

    The different ceramic materials used for ceramic capacitors, paraelectric or ferroelectric ceramics, influences the electrical characteristics of the capacitors. Using mixtures of paraelectric substances based on titanium dioxide results in very stable and linear behavior of the capacitance value within a specified temperature range and low losses at high frequencies.

  7. Capacitive power supply - Wikipedia

    en.wikipedia.org/wiki/Capacitive_power_supply

    By changing the value of the example in the diagram by a capacitor with a value of 330 nF, a current of approximately 20 mA can be provided, as the reactance of the 330 nF capacitor at 50 Hz calculates to = and applying Ohm's law, that limits the current to . This way up to 48 white LEDs in series can be powered (for example, 3.1 V/20 mA/20000 ...

  8. List of capacitor manufacturers - Wikipedia

    en.wikipedia.org/wiki/List_of_capacitor...

    A capacitor is a passive device on a circuit board that stores electrical energy in an electric field by virtue of accumulating electric charges on two close surfaces insulated from each other. This is a list of known capacitor manufacturers, their headquarters country of origin, and year founded. The oldest capacitor companies were founded ...

  9. 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.
