    Post time: Oct-19-2020

    As we all know, the capacitor (C) and the inductor (L) form an LC circuit on the audio circuit for frequency division. When the audio signal of the power amplifier passes through the LC circuit, it will be separated according to the frequency division point and sound cha...Read more »

  • Metallized Film Capacitor
    Post time: Oct-15-2020

    Metallized film USES material discrimination Note: The use of metallized zinc-plated aluminum layer, due to the different materials used, is a big taboo for horizontal audio capacitors. Because the plastic film is galvanized aluminum, its zinc activity is relatively high...Read more »

  • Metallized Film Capacitor
    Post time: Sep-28-2020

    The characteristics of the capacitor are mainly in the electronic circuit: passing AC and blocking DC. The working mode of the capacitor in the circuit is to use the charge and discharge characteristics of the capacitor to achieve the effects of filtering, bypass, coupli...Read more »

  • The difference between the capacitor’s function of Bypass and decoupling
    Post time: Sep-24-2020

    By-pass capacitor is an energy storage device that provides energy to a device. It makes use of the capacitance's frequency impedance characteristic (the ideal capacitance's frequency characteristic decreases with increasing frequency), like a pond, which can make the ou...Read more »

  • Electrolytic Capacitor
    Post time: Sep-15-2020

    When you use aluminum electrolytic capacitors, remember the following:  1.Polarity Regular electrolytic capacitor has polarity. Reverse voltage causes short circuit breakage of the capacitor or leakage of electrolyte. When the polarity in a circuit sometimes reversed or unknown, a bi-polar capaci...Read more »

  • Notice in using film capacitors

  • Voltage Rating of a Capacitor
    Post time: Aug-11-2020

    All capacitors have a maximum voltage rating and when selecting a capacitor consideration must be given to the amount of voltage to be applied across the capacitor. The maximum amount of voltage that can be applied to the capacitor without damage to its dielectric material is generally given in t...Read more »

  • The Dielectric of a Capacitor
    Post time: Aug-04-2020

    As well as the overall size of the conductive plates and their distance or spacing apart from each other, another factor which affects the overall capacitance of the device is the type of dielectric material being used. In other words the “Permittivity” (ε) of the dielec...Read more »

  • Basic knowledge of capacitors
    Post time: Jul-31-2020

    The capacitor is a component which has the ability or “capacity” to store energy in the form of an electrical charge producing a potential difference (Static Voltage) across its plates, much like a small rechargeable battery. There are many different kinds of capacitors ...Read more »
