    Classification and Production Technology of Mica Paper

    Mica is a naturally occurring layered silicate mineral. It has excellent physical and electrical properties and maintains the above properties at high temperature. It has complete chemical inertia and non-flammability. Most importantly, it has the characteristics of high voltage, corona discharge resistance and radiation protection. Therefore, as a very important insulating material, it is widely ...

    What is the Function of Capacitors in Circuits?

    Capacitors, usually referred to as capacitors, have the ability to accommodate charges. They are represented by the letter C. What is the role of capacitors in circuits? Capacitors are one of the most widely used electronic components in electronic devices. They are widely used in the fields of isolated direct traffic, coupling, bypass, filtering, tuning circuit, energy conversion, control and so ...

    How to Identify Series Capacitors?

    A capacitor is composed of two metal electrodes with an insulating dielectric layer between them. When a voltage is applied between two metal electrodes, the energy is stored on the electrodes, so the capacitor is an energy storage element. Any two conductors that are insulated from each other and very close form a capacitor. The parallel plate capacitor is composed of the polar plate and dielectr...

  • What Is A Super Capacitor?
    2016-11-23

    What Is A Super Capacitor?

    A super capacitor (also called supercapacitor, ultracapacitor, farad capacitor)is an electrical component capable of holding hundreds of times more electrical charge quantity than a standard capacitor. This characteristic makes ultracapacitors useful in devices that require relatively little currentand low voltage. In some situations, an ultracapacitor can take the place of a rechargeable low-volt...

    GTCAP Tantalum Electrolytic Capacitor Using Guide

    1.Working Voltage Capacitor fail is affected big by rate of working voltage and rated voltage working voltage. Please considering capacitor reliability when design practical circuits and lower the voltage. Please set voltage below 1/3 of rated voltage when applied in low-impedance circuit (especially filter capacitor in the switch power), and below 2/3 in other circuit. It...
