Tantalum Capacitors

Tantalum capacitors are one of the many types of capacitors and are made of two plates: a solid Ta anode and an electrolyte-soaked Ta oxide cathode. They differ from other types of capacitors in that one of the plates is thinner than the other, making them much smaller than the regular two-plate capacitor. This small size is ideal for supplying power to various portable electronics. They work by storing an electrical charge in the thin layer of Ta oxide between the two plates.

The 13008-020MESB is a tantalum capacitor designed for applications requiring high-temperature and high-humidity operation. It is a radial-style, non-polarized capacitor with a 20 µF rating and 17V maximum voltage rating. The capacitor has an operating temperature range between -55°C and +105°C and can withstand maximum humidity levels of up to 90%.

The working principle of the 13008-020MESB is fairly simple. When an electrical voltage is applied between the two plates, a current flows through the capacitor, which causes the thin Ta oxide layer to be charged. This charge then acts as a dielectric (insulator), which helps prevent the electrical current from flowing through the capacitor. The stored charge, along with the dielectric, create an electric field between the two plates. This field helps to maintain the electrical charge on the capacitor which can be used to power various electronic circuits.

Overall, the 13008-020MESB is a reliable and durable capacitor for applications requiring high-temperature and high-humidity operation. It is small enough to be used in portable electronics, while its dielectric and electric field help to maintain a constant electrical charge which can be used to power electronic circuits.
