Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor, a passive electronic component consisting of two terminals – an anode and a cathode. They utilize a porous tantalum anode, with an electrolyte deposited on it, separated from a solid manganese dioxide cathode. The capacitors come in a variety of packages, including with and without internal heaters and with leaded or surface-mountable connections.

The 293D686X06R3B2TE3 tantalum capacitor is a leaded-style device, with a 2.2 μF capacitance, a 10 VDC working voltage, and a 0.22 ohm ESR. It has a 1.6 mm diameter and is 8 mm tall.

Application Fields

Tantalum capacitors are used for a variety of reasons, such as filtering, bypassing, or tuning in circuits. Some of their most common application fields include:

• Consumer electronics
• Industrial control
• Medical instruments
• Data/telecommunications
• Automotive

The 293D686X06R3B2TE3 is well-suited for applications such as power line filtering and audio decoupling, as well as bypass filtering and tuning of radio frequency circuits.

Working Principle

Tantalum capacitors work according to the same basic principles as other electrolytic capacitors. A metal plate or anode is covered with a porous insulating material such as tantalum powder or metal oxide. This insulating layer separates the metal plate from an electrolyte, which is typically a gel-like or liquid material. The metal plate is then connected to a positive power terminal, while the electrolyte is connected to the negative power terminal.

When a voltage is applied to the capacitor, a chemical reaction occurs at the surface of the metal plate and the materials in the electrolyte deposit a layer of dielectric material on the surface of the plate, forming the capacitance. The capacitance is proportional to the amount of surface area in contact with the electrolyte, and the thickness of the dielectric layer.

The 293D686X06R3B2TE3 is a low impedance electrolytic capacitor, meaning that it can handle high currents and supply large energy reserves. This makes it an ideal choice for a wide range of applications, including automotive systems where high-current load conditions are common.

Conclusion

The 293D686X06R3B2TE3 is a high-quality tantalum capacitor designed specifically for high-current loads. It has a 2.2 μF capacitance, a 10 VDC voltage rating, and a 0.22 ohm ESR. It is well-suited for applications such as power line filtering, audio decoupling, bypass filtering, and tuning of RF circuits.
