Tantalum capacitors contain tantalum powder in a solid, conductive coating, making them particularly ideal for use in electronic circuits with harsh conditions. The ST68-50T1KI is one of many excellent examples to be found across a wide range of applications.

A tantalum capacitor is a type of electrolytic capacitor, which generally consists of two electrodes – one a solid, conductive, and non-porous tantalum powder acting as the anode, and an electrolyte and the other a porous, conductive cathode. While the two electrodes are electrically connected, the anode is immersed in a dielectric medium, typically an aqueous solution of salts that catalyzes the capacitance of the anode. This aqueous solution acts as an electrolyte, transporting ions to and from the cathode to assists in charging and discharging.

The ST68-50T1KI is a tantalum capacitor of the Non-Polarised type which combines superior stability characteristics of the thick film technology with the high capacitance of a tantalum powder electrode. It has very low ESR values, in order for its use in an audio application. Due to its larger package construction, it is designed to cope with the higher voltages needed for stable performance.

The ST68-50T1KI also offers good power absorption characteristics. It is rated at 50VAC and 400VDC, making it ideal for use in power system as well as portable applications. It has exceptional stability at high temperature and good solderability. Furthermore, it offers very good dielectric absorption characteristics, perfect for dealing with high voltage surges and peak loads. This has made it particularly ideal for use in power conditioning, power supplies, and automotive applications.

There are a number of different application fields for the ST68-50T1KI tantalum capacitor, though it is most commonly used in power conditioning, power supplies, automotive, and audio applications. It is very good for use in varied conditions and its high power absorption, temperature stability, very low ESR, and exceptional solderability make it an excellent choice for almost any harsh environment.

The ST68-50T1KI relies on an electric field to work. This electric field, formed by the two electrodes, increases the capacitance of the capacitor as positive charges accumulate on the anode and negative charges accumulate on the cathode. The capacitor takes on random charges from the surrounding environment, but the voltage across it remains constant. This voltage is regulated by the electric field, and the capacitor will hold its charge after the current is removed. Thus, the capacitor acts as an energy storage device that rapidly charges and discharges itself when needed.

In summary, the ST68-50T1KI is an excellent example of a tantalum capacitor, with a wide range of applications in various harsh conditions. Due to its excellent power absorption, temperature stability, very low ESR, and exceptional solderability it is particularly well suited for power system and automotive applications. Its inherently superb construction provides the capability to cope with higher voltages for reliable and stable performance and its electric field-based workings ensure rapid charging and discharging when needed.
