Capaciters and Electronic Condensers


A capacitor is a passive electrical component whose characteristic feature is capacitance. In addition, each real capacitor exhibits other, so-called parasitic properties, such as inductance and resistance, which distinguishes it from a capacitor, which is intended to be an ideal component that has only a capacitance that is also constant and independent of ambient conditions.

Capacitor principle:
The capacitor consists of two conductive plates (electrodes) separated by a dielectric. Electric charges of opposite polarity are applied to each of the plates, which are attracted to each other by an electric force. The dielectric between the plates does not allow the charged particles to come into contact, thereby neutralizing or otherwise discharging the electric charges. At the same time, the dielectric reduces the strength of the electric field of the charges on the plates by its polarization and thus allows the placement of a larger amount of charge.

Capaciters and Electronic Condensers


  • Electrolyte Capacitors

      Electrolytic capacitor are polarized and these are made of Aluminum and one of the two pins are marked as negative pin this pin is also short in length. These Aluminum electrolytic capacitors are used in many applications like power supply DC filtering AC blocking and power on reset circuit in microcontrollers.

  • Film Capacitors

    Metallized polyester film capacitors are very commonly used in transformer less power supply design. Film capacitors, Metallized polyester film capacitors, film dielectric capacitors, or polymer film capacitors, generically called film caps as well as power film capacitors, are electrical capacitors with an insulating plastic film as the dielectric, sometimes combined with paper as carrier of the electrodes. The electrodes of film capacitors may be metallized aluminum or zinc applied directly to the surface of the plastic film.

  • Ceramic.

    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.
