Tantalum Capacitors

Tantalum capacitors are capacitors that use the oxide film of the metal tantalum as the dielectric medium. They are capacitors in which the anode is the tantalum as a metal, and the cathode is a conductive material such as graphite or a suitable solution with a cathode. Tantalum capacitors are polarized capacitors that can only be used in a certain direction. As they have high capacitance, they are widely used in space, aerospace, automotive electronics, and other related fields.

M39003/09-2013/HSD Application Field

The M39003/09-2013/HSD is a surface-mount tantalum capacitor that is widely used in various electronic equipment and digital products. This type is based on EU Directive 2011/65/EU and complies with IEC 61051 and IPC/JEDEC J-STD-020B standards. It is mainly used in telecommunications, computer peripheral devices, automotive electronics, consumer electronics, and many other application fields.

Working Principle

The working principle of the M39003/09-2013/HSD is similar to most tantalum capacitors. When in use, one of the two terminals is connected to the anode and the other to the cathode. The anode is the tantalum metal, while the cathode is a conductive material. The anode is then oxidized to form a thin oxide dielectric film and capacitance is generated between the two components. When an alternating current is applied on the cathode, the capacitor is polarized and stored, and the cathode current is delivered to the anode. This cycle is repeated and the capacitor will be charged and discharged.

Advantages

Tantalum capacitors have a number of advantages over conventional capacitors. Firstly, they have a higher capacitance than other conventional capacitors in the same volume, so they are often used in applications that require a large amount of capacitance. Secondly, their operating frequency is higher than other capacitors, making them suitable for high-frequency circuits. Finally, they have excellent temperature resistance and are resistant to high temperatures, which makes them suitable for use in high-temperature environments.
