Tantalum Capacitors

Tantalum capacitors are electronic components used to store electrical energy and are widespread and very common in the modern electronics and electrical engineering. Tantalum capacitors are very compact and have a relatively large capacitance within a small physical size. They can also handle higher voltage ratings than ceramic capacitors, making them ideal for high-voltage applications. The most common use of tantalum capacitors is in low-voltage power supplies.

199D476X06R3D1V1E3 application field and working principle

The 199D476X06R3D1V1E3 is a general-purpose, solid-state tantalum capacitor. It is used for energy storage in low-voltage and medium-voltage applications, such as AC rectification, DC power supplies, and power line filters. It is also commonly used in energy-saving lamps, mobile phones, computers and other digital products.

Tantalum capacitors have an anode and a cathode, and an electrolyte in between. The electrolyte is typically a solution of an aromatic solvent and an anion complex of tantalum pentoxide.When a voltage is applied across the terminals, electrons are drawn away from the anode, while ions are emitted from the cathode. The ions migrate across the electrolyte to the anode, where they reduce the cations of tantalum pentoxide, forming a dielectric layer of tantalum pentoxide. This layer acts as a barrier between the anode and cathode, creating capacitance.

In order to maintain electrical characteristics, manufacturers of tantalum capacitors use their internal dielectric layer for self-healing. The dielectric will self-heal itself if there is an internal mechanical or electrical failure. It can be done by reverse-biased voltage stress or current surge, causing the metal bleed out of the anode and to create a conductive layer on the surface of the dielectric. This layer acts as a protective layer and repairs the damaged internal structure of the capacitor.

The 199D476X06R3D1V1E3 meets all industry performance and safety standards, making it suitable for a variety of applications. It is widely used in low and medium voltage applications, providing excellent performance and reliability in a diverse range of applications.
