Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor. They are constructed with a tantalum metal oxide anode and typically use manganese dioxide as the electrolyte. They are generally small, but offer high capacitance values in a small package due to their high surface area. Tantalum capacitors have a wide range of applications including main power supply, computer back-up power, electronic communication and audio systems.

The type of tantalum capacitor most commonly used is the 199D105X0035A6V1. This capacitor is usually used in high-current, low-voltage applications. It has a capacitance of 100uF (microfarads) with a working voltage of 6V. Its size is compact and it uses a standard 2-pin surface mount design. It has a wide temperature range and can handle up to 15A of current.

The working principle of a tantalum capacitor is quite simple. When voltage is applied across the terminals, it polarizes the tantalum pentoxide layer. This polarization causes an electrostatic field, which attracts and stores electrons. As the voltage across the capacitor increases, more electrons are stored, thus increasing the capacitance of the capacitor. When the voltage across the capacitor drops, the electrons are released, reducing the capacitance of the capacitor.

Tantalum capacitors are widely used in electronic circuits, especially in power supplies, decoupling circuits, inrush current limiting circuits, and filters. They also have uses in industrial and military applications. Due to their wide temperature range, high capacitance values and small size, they are a very popular choice for all types of applications.

Tantalum capacitors are generally reliable components, but they do have some drawbacks. They are sensitive to overvoltage, which can cause permanent damage. As the voltage across the capacitor increases, the cathode will become progressively more negatively charged. Beyond a certain point, the oxide layer will breakdown, causing the capacitor to fail. Additionally, if the anode is not connected properly, it can result in an open circuit.

In conclusion, tantalum capacitors are widely used in many electronics applications. They are reliable components, but can be damaged by extreme temperatures or overvoltage. The 199D105X0035A6V1 capacitor has a wide temperature range and can handle up to 15A of current. Because of its small size and high capacitance, it is an excellent choice for a variety of uses.
