Tantalum Capacitors

A tantalum capacitor, also known as a dry solid electrolytic capacitor, is an electronic component consisting of a tantalum metal powder and an insulating oxide layer of tantalum pentoxide. It is an electrolytic capacitor and typically has a capacitance value in the range of 1 to 2000 μF with a rated voltage of 4 to 50 VDC. As compared to other types of electrolytic capacitors, tantalum capacitors are smaller, lighter-weight, and feature a longer life span.

The specific application field and working principle of the TPSD476K016R0200 tantalum capacitor is for general-purpose 85°C radial-leaded polyester-filmed capacitors with solid tantalum anode and limited volumetric efficiency. These capacitors have a capacitance value of 16 μF, a rated voltage of 6.3VDC, and an operating temperature range of -55°C to +85°C.

The TPSD476K016R0200 capacitor is a solid tantalum capacitor with manganese dioxide as the electrolyte. The metal cases and wrap-around epoxy terminations isolate the capacitor element, creating a seal that prevents leakage and electrolytic corrosion. This capacitor also includes a tear-resistant polyester film dielectric and a low-inductance, high-permeability terminator that helps reduce ESR.

When an electric current is applied to a tantalum capacitor, an oxide layer is formed on one of the conductors (known as an anode). The oxide layer acts as a dielectric, increasing the capacitance of the capacitor. This oxide layer also prevents reverse-charging current, ensuring the reliability and stability of the tantalum capacitor. The construction and size of the capacitor determines its capacitance value and rated voltage.

In addition to having a compact size and weighing less than typical aluminum electrolytic capacitors, tantalum capacitors also have better temperature stability and are able to maintain a high capacitance over their entire life cycle. They are resistant to vibration and shock, a feature which makes them suitable for use in consumer electronics and military applications. Furthermore, the use of dielectric films instead of wet electrolytes enables operating temperatures up to 125°C, making them appropriate for high-temperature applications.

Overall, the TPSD476K016R0200 capacitor is a reliable and robust type of tantalum capacitor, offering excellent capacitance stability, voltage withstand ratings, and long operational life. Its size, weight, and temperature stability make it an ideal choice for a variety of commercial, military, and industrial applications.
