Tantalum - Polymer Capacitors

Tantalum - Polymer capacitors, also referred to as electrolytic capacitors, are a type of capacitor composed of a layer of metal-semiconductor material electrode, such as tantalum metal, and an organic polymer film. This provides a large amount of capacitance with minimal size and highest efficiency when compared to other types of capacitors. As a result, tantalum – polymer capacitors are widely used in high frequency filters and are found in a variety of electronics, including cell phones, computers, audio systems, and other communication systems.

Due to its high capacitance and voltage rating, the T550B476K050AH4250 capacitor is also suited for use in voltage-step-down power supplies and Li-Ion battery charge circuits.

A basic tantalum – polymer capacitor works on the same principle as other types of capacitors, which involve the creation of an electrical field between two conductive surfaces. One of these surfaces is the metallic electrode, made from a material such as tantalum metal. The other is a thin layer of polymer film, which acts as the dielectric between the two surfaces. When a voltage is applied to the capacitor, the electric field causes a current to flow between the two surfaces. This current produces a stored charge, creating the capacitance of the device.

Tantalum – polymer capacitors are a great choice for high frequency applications due to their minimal size, high capacitance and excellent frequency characteristics. The T550B476K050AH4250 capacitor is one of the most common and reliable varieties of tantalum – polymer capacitors. This device is suitable for various types of audio systems and high frequency filters, as well as voltage-step-down power supplies and Li-Ion battery charge circuits.
