Tantalum Capacitors

Tantalum capacitors are solid-state, electrolytic components that store a certain amount of electricity typically derived from a DC or low frequency AC source. They are one of the most popular types of capacitors used around the world and are used in a wide range of electronics applications. In most cases, tantalum capacitors consist of three layers, an anode and cathode, with a porous tantalum anode separated by a dielectric spacer and a separated electrolyte.

T322B475K010AT Application Field and Working Principle

The T322B475K010AT is a commonly used Low ESR (Equivalent Series Resistance) surface mount MnO2 (Manganese Dioxide) electrolytic capacitor made from tantalum. This capacitor is used for applications where high current and reliable power is needed, such as buzzer drivers in cellphones, audio amplifiers and digital cameras. The capacitor includes an integrated bias voltage compensator, which allows it to be used in high and low ESR environments.

The working principle of the T322B475K010AT is based on the movement of electrons that flows between two plates of the same material (a tantalum anode and a MnO2 cathode), separated by an electrically-insulating layer. The amount of charge stored in the capacitor is determined by the capacitance, which is determined by the area, permittivity and spacing between the two plates. Because capacitors are made of an anode, cathode and dielectric spacer, they are called “electrolytic” capacitors.

When current is applied to the capacitor, it begins to fill with electrons from the anode side. The capacitor will remain filled until the current is cut off or the capacitor is fully discharged. Because this capacitor is rated with a low ESR, it is mainly used for apps requiring high current, such as audio amplifiers, buzzer drivers, or digital cameras. This capacitor also works well in circuits governed by higher frequency AC or low frequency DC, such as those found in audio equipment or automated robotics.

The T322B475K010AT has numerous advantages that make it an ideal choice for various high current applications. The capacitor has a high working voltage of 16V and a rated voltage of 10V. It also has a low ESR of 1.5mΩ. It is also known for its excellent temperature stability and long-term reliability. The capacitor also has a good load life of 3000 hours at a rated temperature of 85℃.

In conclusion, the T322B475K010AT is a reliable and high current surface mount MnO2 tantalum capacitor that is an ideal choice for a variety of applications. It has a high working voltage and low ESR, excellent temperature stability, long-time reliability and good load life. Applications such as buzzer drivers in cellphones, audio amplifiers, and digital cameras benefit from the use of this capacitor.
