  1. Capacitor classification

  2. According to the structure can be divided into: fixed capacitor, variable capacitor, trimmer capacitor. According to the dielectric material can be divided into: gas dielectric capacitor, liquid dielectric capacitor, inorganic solid dielectric capacitor, organic solid dielectric capacitor electrolytic capacitor. Divided by polarity: there are polar capacitors and non-polar capacitors. Capacitance refers to the amount of charge stored at a given potential difference; capacitance is one of the most widely used electronic components in electronic devices. Interpretation is the physical application range that characterizes the ability of a capacitor to hold a charge. It is widely used in blocking, coupling, bypassing, filtering, tuning loops, energy conversion, control circuits, etc. Symbol C represents the capacitance unit Farad (F), microfarad (uF) ), Pefala (pF), three units converted to: Pefala (pF), 1F = 10 ^ 6uF = 10 ^ 12pF capacitor in the circuit of the role of capacitance in the circuit: with blocking DC, connected AC, blocking Low frequency characteristics are widely used in coupling, DC blocking, bypassing, filtering, tuning, energy conversion and automatic control.
