Tantalum Capacitors

A tantalum capacitor is an electronic component that is used to store energy or act as a dynamic filter. Similar to an aluminum electrolytic capacitor, the 594D476X0016C2W model consists of two conducting plates where one is made of a tantalum base and the other is an oxide layer. The oxide layer acts as the dielectric or insulating layer between the two plates. This structure gives the device a organic material-based non-polar capacitor with very low leakage current, relatively low capacitance change over time, and outstanding volumetric efficiency compared to other types of capacitors.

Application Field and Working Principle

Tantalum capacitors are used in a variety of applications in consumer electronics, medical, telecommunications, automotive, instrumentation, and military/aerospace. The 594D476X0016C2W model is typically used in industrial power supplies and will provide superior performance in harsh environments due to its excellent hermeticity and resistivity to extreme conditions.

The contents of the 594D476X0016C2W Tantalum capacitors can be compartmentalized by four parts. The first part is an anode made of tantalum, which acts as an electrode. The second part is a conductive layer referred to as an electrolyte. The third part is a porous cathode, which acts as a source of electrons. The fourth part is a junction between the anode and cathode, which is made up of solid electrolyte material. The capacitors can also be classified into two categories - wet and dry.

The capacitor’s working principle is based on the fact that a dielectric is placed between two metal plates with opposite electric charges. When an external electric field is applied, the opposite charges attract each other and form an electric field. This electric field stores energy in the form of electrical potential energy, which in turn induces a current flow in the circuit. The amount of current that the capacitor can store is proportional to its capacitance, which is defined as the ratio between the charge stored and the applied voltage.

The 594D476X0016C2W Tantalum capacitor has a wide selection of features, including its surface mount design, high capacitance, low self-inductance, low leakage current, excellent stability, hermeticity and resistivity to harsh environmental conditions.
