Tantalum Capacitors

A tantalum capacitor is a type of electrolytic capacitor, which features an oxide anode, a tantalum cathode and a solid electrolyte made of water and organic acid derivates. They contain a porous pellet of tantalum pentoxide as the anode, which the electrolyte permeates. This makes them especially suitable for applications which require high capacitance values in a small space, which is why they are commonly used in computers and portable electronics.

T95R227K016HZSL application field and working principle

The T95R227K016HZSL tantalum capacitor is commonly used in a variety of applications due to its reliable performance and long life. It is an SMT (SMD or Surface Mount Device) capacitor with a polarized design, meaning it should never be reversed or substituted with a differently-polarized capacitance in a circuit. It features a capacitance of 22uF (microfarads) and a standard tolerance of ±10%. It has a maximum voltage rating of 6.3V and a maximum leakage current of 0.02µA at 20°C.

The T95R227K016HZSL tantalum capacitor works on the principle of electrochemical capacitor, which store energy in the form of electric charge between two solid metallic plates. The plates are separated by a non-conductive (dielectric) medium such as air, paper, ceramic, plastic, etc. When a voltage is applied between the two plates, electrons flow from one plate to the other, resulting in a displacement of charge. This displacement of charge creates a potential difference between the two plates and thus the capacitor can act as a power source.

The internals of the T95R227K016HZSL are constructed of a sintered tantalum anode, a dielectric solvent mixture and a silver manganese dioxide cathode. The sintered tantalum anode is a powder made of porous tantalum alloy particles, while the solvent mixture is composed of a blend of nitrate and alcohol. The silver manganese dioxide cathode is a combination of silver, manganese and oxygen atoms. It acts as an ionic conductor so that when a voltage is applied to the capacitor, it can store electric charge. When the voltage is removed, the electrons flow back into the saturated electrolyte liquid, ready to be used again.

The above mentioned T95R227K016HZSL tantalum capacitor is widely used in consumer electronics and industrial applications because of its small size, high operating temperatures, and long life. It can be found in products like laptops and portable audio devices, hand-held or remote control items such as TVs and music players, game consoles, and industrial machinery. Additionally, it can be used in automotive and marine electronics such as radios and GPS units.
