Tantalum capacitors are electrochemical capacitors that use a tantalum metal oxide as the electrolyte between one or more anodes and cathodes. Tantalum capacitors are used in electronic circuits that require high levels of capacitance, voltage, and temperature ratings. They are widely used in a variety of applications, from consumer electronics to automotive and aerospace applications.

The T86C475M020EAAS is a Tantalum capacitor suitable for use in portable electronics, industrial equipment, and automotive applications. It is a molded two-terminal package with an anode lead and a cathode lead (terminals A and B, respectively) and has a rated capacitance of 47µF, a rated voltage of 20V, an operating temperature range from -55°C to 85°C, and a dissipation factor of 1.25%. It also features a long life span—up to 1000 times the life of an equivalent aluminum capacitor.

The basic working principle of a Tantalum capacitor is based on the same principles as in any other capacitor—a capacitor stores electrical charge between two conductive plates separated by an insulating material. A Tantalum capacitor typically uses tantalum as the anode (one of the conductive plates) with a tantalum oxide as the electrolyte and an organic polymer as the cathode (other conductive plate). The polymer cathode helps reduce the risks of thermal runaway and the chance of short circuit.

When connecting the T86C475M020EAAS, the anode lead should be connected first, followed by the cathode lead. The capacitor should be mounted so that its main body is perpendicular to the main board and avoid subjected to excessive vibration or shock to prevent damage. It is also important to remember to maintain a safe distance between adjacent components, particularly those that may generate heat.

In addition to portable electronics, industrial applications, and automotive applications, the T86C475M020EAAS is also well-suited for use in power supplies and medical equipment. Its low profile packages and long life span make it an ideal candidate for use in harsh and compact environments. When used in pulsed circuitry applications, its near-zero ESR (equivalent series resistance) results in improved frequency response performance and better insertion losses. It also offers between 10 to 30 times the ripple current of a standard aluminum capacitor, ensuring reliable performance.

In conclusion, the T86C475M020EAAS is a robust and reliable capacitor suitable for use in a variety of applications. It features a wide operating temperature range, a low ESR, and long life, making it an excellent choice for portable electronics, industrial equipment, automotive, medical, and power supply applications. It is also well-suited for use in pulsed circuitry applications, and its small size and low profile allows for use in compact and harsh environments.
