Tantalum capacitors, or Ta capacitors, are an electronic component characterized by their permanent assembly with two electrodes, where one of them is made of tantalum and the other of an oxide. This oxide acts as a dielectric layer and provides high capacitance ratings. Tantalum capacitors are made of sintered tantalum powder, with electrodes on the top and bottom, and may have various forms, such as molded tubular case, radial-leaded, surface-mounted chips, etc. Most of them have small dimensions, high capacitance density, long life and low voltage and temperature coefficients, making them an ideal choice for building electronic circuit designs.

The TR3A225K020C4000 is one type of tantalum capacitor. The "TR3" indicates the maximum voltage rating, which is 30V DC. This is followed by the capacitance value of 22μF. The "K" indicates the maximum temperature coefficient, which is ±10%. The "0" stands for the tolerance at -20%. Lastly, the "C4000" is the case size of the capacitor, with a diameter of 3mm and a height of 2.5mm. This makes the TR3A225K020C4000 an ideal fit into applications with limited space.

The primary application field of the TR3A225K020C4000 is in the automotive industry, where they are commonly used as filters, interference suppressors and switches. They are also widely used as control components in power supplies and uninterruptible power supplies (UPSs). In audio devices such as amplifiers and preamps, this capacitor type is used primarily for decoupling and specific filtering.

The working principle of the TR3A225K020C4000 relies on the basic concept of capacitance. When two surfaces separated by a dielectric material are connected to a DC voltage, the electric field produces an electrical charge on both surfaces, resulting in stored electrical energy. The rate of charge stored in the capacitor is equal to the rate of energy being dissipated, meaning that the voltage across the capacitor is held constant. This is why large AC components are filtered out, passing only the required DC signals.

Due to their small form factor and high capacitance values, Tantalum capacitors are the ideal choice for applications with limited space and high current loads. The TR3A225K020C4000 is no exception and is widely used in the automotive and audio applications, thanks to its impressive performance capabilities. With its long life, high capacitance density and low temperature coefficients, this type of capacitor ensures reliable service for many years.
