  2. Tantalum capacitor - Wikipedia

    en.wikipedia.org/wiki/Tantalum_capacitor

    Tantalum capacitors in different styles: axial, radial and SMD-chip versions (size comparison with a match) 10 μF 30 VDC-rated tantalum capacitors, solid electrolyte epoxy-dipped style. A tantalum electrolytic capacitor is an electrolytic capacitor , a passive component of electronic circuits .

  3. 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.

  4. Capacitor types - Wikipedia

    en.wikipedia.org/wiki/Capacitor_types

    The rate of aging of Class 2 ceramic capacitors depends mainly on its materials. Generally, the higher the temperature dependence of the ceramic, the higher the aging percentage. The typical aging of X7R ceramic capacitors is about 2.5% per decade. [67] The aging rate of Z5U ceramic capacitors is significantly higher and can be up to 7% per decade.

  5. Tantalum - Wikipedia

    en.wikipedia.org/wiki/Tantalum

    Tantalum electrolytic capacitors exploit the tendency of tantalum to form a protective oxide surface layer, using tantalum powder, pressed into a pellet shape, as one "plate" of the capacitor, the oxide as the dielectric, and an electrolytic solution or conductive solid as the other "plate".

  6. Polymer capacitor - Wikipedia

    en.wikipedia.org/wiki/Polymer_capacitor

    Polymer tantalum electrolytic capacitors are essentially tantalum capacitors in which the electrolyte is a conductive polymer instead of manganese dioxide, see also tantalum capacitor#Materials, production and styles Tantalum capacitors are manufactured from a powder of relatively pure elemental tantalum metal.

  7. Dielectric absorption - Wikipedia

    en.wikipedia.org/wiki/Dielectric_absorption

    The capacitor shall be charged at the DC voltage rating for 60 minutes. Then the capacitor shall be disconnected from the power source and shall be discharged for 10 s. The voltage regained on the capacitor terminals (recovery voltage) within 15 minutes is the dielectric absorption voltage.

  8. Applications of capacitors - Wikipedia

    en.wikipedia.org/wiki/Applications_of_capacitors

    Fortunately, most solid tantalum capacitor failures will be immediate and very evident. Once in application solid tantalum capacitor performance will improve over time and the chances of a failure due to component mis-manufacturing decrease. Wet tantalums are a type of the electrolytic capacitor, using a tantalum pellet in an electrolytic ...

  9. 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 ...
