Tantalum capacitors are a type of electrolytic capacitor composed of tantalum metal, which acts as an anode, and covered by an insulating oxide film as the dielectric. Mainly used in portable electronic devices and computer motherboard circuit, they have many advantages, such as small size, large capacitance, long life, low cost, and high temperature resistance. Now let\'s take a closer look at TPSB476M006P0250, a particular Tantalum capacitor, and understand its application field and working principle.

TPSB476M006P0250, abbreviated as MP476, is a radial lead type low impedance solid tantalum capacitor. It is widely used to support electrical supply systems in applications with broad switching and high ripple currents, such as motor control, automation and power conversion of electronic systems .

MP476 is mainly composed of a tantalum part, a dielectric oxide film, anode and cathode lead-wire, and an outer casing. The tantalum part contains a porous material and works as anode, and the dielectric oxide film functions as the capacitive element. The anode lead-wire and the cathode lead-wire are respectively welded on the anode and the cathode, with the help of gold wire braiding, while the outer casing is built with metal material, providing mechanical strength and heat dissipation.

When the capacitor is in operation, electrons are transferred between the anode and the cathode through the dielectric oxide film, and electric energy is stored. At the same time, under AC or DC voltage, the amount of electricity that can be stored in the capacitor is decided by the dielectric constant of the capacitor. When the voltage applied is equal to the capacitor\'s rated working voltage, the leakage current begins to increase and the capacitor is damaged.

MP476 is especially suitable for high ripple current application in DC-to-DC converters, motor drives, DC servo systems, access control, aircraft, satellite avionics systems, telecommunications systems and other precision electronic equipment.

To ensure safe use in DC circuits and specially designed AC circuits, features like the AEC-Q200 compliant, RoHS compliance and SELV (safety extra low voltage) capability are all supplied. Moreover, the oiltight coating of the MP476 gives it excellent protection when used in damp and corrosive environments.

In conclusion, MP476 tantalum capacitor is a high quality electrolytic capacitor beneficial to many electrical systems, and its application field as well as working principle can be understood from the above explanation.
