Tantalum Capacitors

Tantalum capacitors are types of capacitors composed mainly of tantalum. The most common type of tantalum capacitors are formed by pressing powdered tantalum into a cylindrical shape, and then it is placed in a sealed can and a lid is added. The can forms the second electrode. Generally they are constructed in two varieties: wet and dry.

In its simplest form, the electrolyte that comes in contact with the capacitor elements is the dielectric material, which in this case is tantalum pentoxide. Tantalum pentoxide is an oxide of tantalum that forms a thin film layer, which is then further sealed inside a solid case. This seals off the electrolyte and prevents it from being exposed to air and humidity. This film layer serves as an electrical insulator and as a dielectric.

The 13008-070MESC application field is one that requires an ultra-small, single-ended molded tantalum capacitor. This capacitor is most commonly used as a surface mountable device, and it works great in any environment that needs an extremely small device with a great degree of tolerance. Its design is a cylindrical structure that is coated with tantalum pentoxide, which acts as the dielectric. It is small enough to fit almost any device size.

The capacitor’s working principle is based on the degree of capacitance of its internal structure. By increasing or decreasing the voltage across the capacitor, the distance between the electrodes changes, and so too does the capacitance of the device. This is exploited by the circuit design in order to ensure that the correct voltage is applied across the capacitor and that there is no overvoltage or over-current. Additionally, by changing the distance of the electrodes due to the applied voltage, the capacitance of the capacitor changes, thus allowing the user to adjust the electrical power applied to the circuit.

The 13008-070MESC is a useful component for applications fields that need a simple solution that is small in size, and offers a great amount of tolerance. Its unique design ensures its high reliability and the stable image of a high-quality working product. It is an excellent choice for use as an ultra-tiny, single-ended molded tantalum capacitor.
