  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. Tantalum - Wikipedia

    en.wikipedia.org/wiki/Tantalum

    Tantalum is a chemical element; it has symbol Ta and atomic number 73. Previously known as tantalium, [citation needed] it is named after Tantalus, a figure in Greek mythology. [11] Tantalum is a very hard, ductile, lustrous, blue-gray transition metal that is highly corrosion-resistant.

  4. Dielectric absorption - Wikipedia

    en.wikipedia.org/wiki/Dielectric_absorption

    Dielectric absorption is the name given to the effect by which a capacitor, that has been charged for a long time, discharges only incompletely when briefly discharged.. Although an ideal capacitor would remain at zero volts after being discharged, real capacitors will develop a small voltage from time-delayed dipole discharging, [1] a phenomenon that is also called dielectric relaxation ...

  5. 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.

  6. Electromagnetically induced acoustic noise - Wikipedia

    en.wikipedia.org/wiki/Electromagnetically...

    When the capacitor voltage/current waveform is not constant and contains time harmonics, some harmonic electric forces appear and acoustic noise can be generated. [13] Ferroelectric capacitors also exhibit a piezoelectric effect that can be source of audible noise. This phenomenon is known as the "singing capacitor" effect. [14]

  7. Equivalent series resistance - Wikipedia

    en.wikipedia.org/wiki/Equivalent_series_resistance

    Capacitors and inductors as used in electric circuits are not ideal components with only capacitance or inductance.However, they can be treated, to a very good degree of approximation, as being ideal capacitors and inductors in series with a resistance; this resistance is defined as the equivalent series resistance (ESR) [1].

  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 types - Wikipedia

    en.wikipedia.org/wiki/Capacitor_types

    Aluminum, tantalum and niobium electrolytic capacitors are named after the material used as the anode and the construction of the cathode (electrolyte) Polymer capacitors are aluminum, tantalum or niobium electrolytic capacitors with conductive polymer as electrolyte; Supercapacitor is the family name for:
