Tantalum Capacitors

Tantalum capacitors are electronic components that are commonly used in a variety of consumer electronics and industrial applications. These capacitors utilize tantalum oxide as the dielectric, which gives them a high capacitance within a small size. A tantalum capacitor is typically composed of two tantalum powder plates separated by a dielectric material, usually an electrolyte material, encased in a metal housing. The plates are also connected to two terminals. The two terminals are then connected to either an anode or a cathode, depending on the application being utilized.

T350K476K020AT Application Field and Working Principle

The T350K476K020ATcapacitor is a radial, lead-free, surface-mount tantalum capacitor with a lead-free Sn/Bi plating. It has a capacitance of 17µF (microfarads) with a rated voltage of 6.3V and an operating temperature range of -55°C to +125°C. The T350K476K020AT is widely used in consumer electronics, industrial applications and medical devices.

The working principle of the T350K476K020AT tantalum capacitor is based on electrochemical capacitance. In this type of capacitance, the electrolyte or dielectric material acts as the separating medium between the two plates, allowing a current to flow from one plate to the other. When an electric field is created, an electric charge is stored on each of the plates and this creates a capacitance. The charge stored on the plates varies with the applied voltage, which allows for different levels of current flow through the capacitor.

The electrochemical capacitance of a tantalum capacitor occurs by adsorption of a thin layer of dielectric oxide on the surface of the tantalum powder. This oxide layer creates a barrier between the plates and the surrounding electrolyte, thus allowing the current to travel more easily. As the electric field changes, the charge stored on the plate varies. Over time, the oxide layer on the plate breaks down and becomes less effective, resulting in a decrease in the capacitor\'s capacitance.

The T350K476K020AT tantalum capacitor is a high-temperature device, making it suitable for use in applications exposed to extreme temperatures. It is also an ideal choice for applications with high frequency switching and high circuit current.

Tantalum capacitors are widely used in industrial, consumer and medical applications. They are a reliable and cost-effective choice for both high voltage and high temperature applications. The T350K476K020AT capacitor is an excellent example of a high-quality tantalum capacitor.
