Tantalum Electrolytic Capacitors

RG ALLEN Tantalum Electrolytic Capacitors:

rga Tantalum capacitors Tantalum capacitors offer a very high charge per unit of volume, a long lifetime and a high reliability. They are used in consumer goods and more specialized niches. A tantalum capacitor is a type of electrolytic capacitor and usually consists of a pellet of tantalum metal that acts as an anode, is covered by an insulating oxide layer which forms the dielectric and is surrounded by conductive material that acts as a cathode. Tantalum capacitors are different from other capacitors by having high capacitance per weight and volume. Tantalum capacitors have lower ESR (equivalent series resistance), higher operating temperature and lower leakage than other types of electrolytic capacitors.

A tantalum capacitor is a specific type of electrolytic capacitor. It is made from a metal called tantalum, which is where it gets its name. Tantalum acts as an anode. The capacitor itself is covered in a thin layer of oxide, which allows it to act as the dielectric. It is surrounded by a conductive cathode. One of the major benefits of tantalum capacitors is that their design allows for a very thin layer of dielectric, which allows for higher capacitance than other types of capacitors made from different types of materials. These types of capacitors are generally polarized, which means that in practice they can only be connected to a direct current power supply that has been designed while observing the appropriate terminal polarity. They have excellent stability over time and superior frequency characteristics when compared to different types of similar capacitors that are made from different materials.
