  2. Ceramic capacitor - Wikipedia

    en.wikipedia.org/wiki/Ceramic_capacitor

    The different ceramic materials used for ceramic capacitors, paraelectric or ferroelectric ceramics, influences the electrical characteristics of the capacitors. Using mixtures of paraelectric substances based on titanium dioxide results in very stable and linear behavior of the capacitance value within a specified temperature range and low losses at high frequencies.

  3. Capacitor types - Wikipedia

    en.wikipedia.org/wiki/Capacitor_types

    Capacitors for AC applications are primarily film capacitors, metallized paper capacitors, ceramic capacitors and bipolar electrolytic capacitors. The rated AC load for an AC capacitor is the maximum sinusoidal effective AC current (rms) which may be applied continuously to a capacitor within the specified temperature range.

  4. Capacitor - Wikipedia

    en.wikipedia.org/wiki/Capacitor

    Capacitors, especially ceramic capacitors, and older designs such as paper capacitors, can absorb sound waves resulting in a microphonic effect. Vibration moves the plates, causing the capacitance to vary, in turn inducing AC current. Some dielectrics also generate piezoelectricity. The resulting interference is especially problematic in audio ...

  5. Applications of capacitors - Wikipedia

    en.wikipedia.org/wiki/Applications_of_capacitors

    Mains filter capacitors are usually encapsulated wound-plastic-film types, since these deliver high voltage rating at low cost, and may be made self-healing and fusible. Mains filter capacitors are often ceramic RFI/EMI suppression capacitors. The additional safety requirements for mains filtering are:

  6. Decoupling capacitor - Wikipedia

    en.wikipedia.org/wiki/Decoupling_capacitor

    Typical impedance curves of X7R and NP0 ceramic capacitors Impedance curves of aluminum electrolytic capacitors (solid lines) and polymer capacitors (dashed lines). A bypass capacitor is often used to decouple a subcircuit from AC signals or voltage spikes on a power supply or other line.

  7. Ceramic - Wikipedia

    en.wikipedia.org/wiki/Ceramic

    Ceramic material is an inorganic, metallic oxide, nitride, or carbide material. Some elements, such as carbon or silicon, may be considered ceramics. Ceramic materials are brittle, hard, strong in compression, and weak in shearing and tension. They withstand the chemical erosion that occurs in other materials subjected to acidic or caustic ...

  8. List of capacitor manufacturers - Wikipedia

    en.wikipedia.org/wiki/List_of_capacitor...

    A capacitor is a passive device on a circuit board that stores electrical energy in an electric field by virtue of accumulating electric charges on two close surfaces insulated from each other. This is a list of known capacitor manufacturers, their headquarters country of origin, and year founded. The oldest capacitor companies were founded ...

  9. Co-fired ceramic - Wikipedia

    en.wikipedia.org/wiki/Co-fired_ceramic

    Co-fired ceramic devices are monolithic, ceramic microelectronic devices where the entire ceramic support structure and any conductive, resistive, and dielectric materials are fired in a kiln at the same time. Typical devices include capacitors, inductors, resistors, transformers, and hybrid circuits.
