Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are high-capacity and high-capacitance capacitors available in a wide range of packages. They are typically made from a tantalum powder pressed and sintered into a pellet about the size of a pea, then covered with a dielectric oxide film and, finally, a metal cap. Generally, tantalum capacitors consist of two or three terminals. Since their introduction in the 1950s, Tantalum capacitors have become increasingly popular due to their high capacitance, long-term stability, and small physical size.

TPSA475K016R2000 Application Field and Working Principle

The TPSA475K016R2000 is a high-temperature, high-reliability tantalum capacitor, and is a popular choice for military and aerospace applications. It is a polarized surface mount capacitor with a rated voltage of 16VDC and a tolerance of ±20%. Its capacitance is 475K microfarads, and maximum operating temperature is up to 125℃. Its substrate is made of manganese dioxide, and its anode is tantalum powder. The basic design of this capacitor is two lead pins, an anode, a dielectric oxide and a cathode.

The basic working principle of the tantalum capacitor is based on the behavior of electric current inside the capacitor plate. When a voltage is applied to the capacitor, an electric current flows through the capacitor plate. This electric current flows from anode to the cathode, and charges up the capacitor. When the capacitor is fully charged, the electric current stops flowing. However, since the capacitor is not a perfect insulator, a small leakage current always exists, which keeps the capacitor charged.

Since the TPSA475K016R2000 has high temperature, high reliability, and a high capacitance, it is also suitable for power management, where higher operating temperatures and large currents require exceptional reliability and durability. By using this capacitors, users can get better performance, increased efficiency and power savings.

In conclusion, the TPSA475K016R2000 is a high-reliability, high-temperature, high-capacitance tantalum capacitor suitable for military and aerospace applications. It offers long-term stability, smaller physical size, and better performance for power management.
