    Electrolytic capacitors use a chemical feature of some special metals, historically called valve metals, which can form an insulating oxide layer. Applying a positive voltage to the tantalum anode material in an electrolytic bath forms an oxide barrier layer with a thickness proportional to the applied voltage. This oxide layer serves as the dielectric in an electrolytic capacitor. The properties of this oxide layer compared with tantalum oxide layer are given in the following table:

    What Are Tantalum Capacitors?CharacteristicsConstruction and Properties of Tantalum CapacitorsApplications For Tantalum CapacitorsTantalum capacitors are a subtype of electrolytic capacitors. They are made of tantalum metal which acts as an anode, covered by a layer of oxide which acts as the dielectric, surrounded by a conductive cathode. The use of tantalum allows for a very thin dielectric layer. This results in a higher capacitance value per volume, superior frequency characteristics compared to many other types of capacitors and excellent stability over tSee more on capacitorguide

    Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, it is named after Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum. Its main use today is in tantalum capacitors in elec

    Tantalum capacitor failure modes. One of the disadvantages of having a very thin oxide layer as the dielectric is that it is not particularly robust. As a result, care has to be taken when using tantalum capacitors. Tantalum capacitors are reliable provided they are operated within their specification limits.

  • Capacitor Codes & Markings Electronics Notes

    For leaded tantalum capacitors the polarity markings indicate the positive lead. A "+" sign is placed close to the positive lead. When new, a further polarity making may be used because it may be seen that the positive lead is longer than the negative one.

  • Electrolytic capacitor Wikipedia

    An electrolytic capacitor (occasionally abbreviated e-cap) is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization.This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor.
