Capacitors

  • What is a capacitor?

    Capacitor, also known as "capacitance", refers to the storage of free charge under a given potential difference, which is recorded as C, and the international unit is farad (f). Generally speaking, the charge will move under force in the electric field. When there is a medium between the conductors, it hinders the charge movement and makes the charge accumulate on the conductor, resulting in the cumulative storage of charge. The amount of stored charge is called capacitance. conformal-coated tantalum capacitors

    Capacitance is the ability to hold charge. Any electrostatic field is composed of many capacitors. If there is an electrostatic field, there is a capacitance. Capacitance is described by electrostatic field. It is generally believed that an isolated conductor forms a capacitance with infinity, and the conductor grounding is equivalent to being connected to infinity and connected with the earth as a whole.HVAC capacitors

    Capacitance (or electrical capacity) is a physical quantity that shows the ability of a capacitor to hold charge. Physically speaking, capacitance is a static charge storage medium, which may exist permanently. This is its characteristic. It has a wide range of uses. It is an indispensable electronic component in the field of electronics and power. It is mainly used in power filtering, signal filtering, signal coupling, resonance, filtering, compensation, charge and discharge, energy storage, DC isolation and other circuits.power film capacitors

    Calculation formula of capacitance:

    For a capacitor, if the potential difference between the two stages is 1 volt with 1 Bank of electricity, the capacitance of the capacitor is 1 farad, that is, C = q / u. However, the capacitance is not determined by Q (charge) or u (voltage), that is, the determination formula of capacitance is: C= ε rS/4πkd 。 Among them, ε R is the relative dielectric constant, s is the positive area of the capacitor plate, D is the distance between the capacitor plates, and K is the electrostatic constant. Common parallel plate capacitor, the capacitance is C= ε S/d( ε Is the dielectric constant of the medium between the plates, ε=ε r ε 0 ε 0 = 1 / 4 π K, s is the area of the plates, D is the distance between the plates).

    Definition:

    Calculation formula of electric potential energy of capacitor: e = C * (u ^ 2) / 2 = Qu / 2 = (Q ^ 2) / 2C

    Calculation formula for parallel connection of multiple capacitors: C = C1 + C2 + C3 +... + CN

    Multi capacitor series calculation formula: 1 / C = 1 / C1 + 1 / C2 +... + 1 / cn

    Three capacitors in series: C = (C1 * C2 * C3) / (C1 * C2 + C2 * C3 + C1 * C3)
