Tantalum Capacitors

Tantalum capacitors are electrochemical capacitors that use tantalum metal for the anode and are characterized by a very high capacitance-to-volume ratio and low overall series resistance. The 13008-040KESA is a type of surface mount tantalum capacitor that is often used in automotive and industrial applications, especially in high current circuits such as power supplies and motor drives.

Application Field

The 13008-040KESA is well suited to applications involving extreme environmental conditions. Its excellent thermal stability and wide operating temperature range, from -55°C up to +155°C, make it well suited for automotive and industrial applications. In addition, its low ESR (equivalent series resistance) makes it an ideal choice for high current applications, as the ESR contributes to heater power dissipation and temperature rise. Being as small as possible is an important factor in automotive and most other modern electronic designs, and the 13008-040KESA is one of the smallest SMD (surface mount device) tantalum capacitor available, while still retaining its excellent performance.

Working Principle

Tantalum capacitors function basically the same as any other electrolytic capacitor. An electrolyte, usually manganese dioxide, is applied to a porous anode and covered with a paper dielectric insulator. A conductive metallization system is printed on the dielectric insulator, allowing for electrical contact. The manganese dioxide provides both the electrical activation and the mechanical stability of the device. Once the capacitor is polarized and connected to a power source, electrical current will flow through the electrolyte, resulting in the capacitor\'s ability to store energy.
