T491B474M035AT Tantalum Capacitors: Application Field and Working Principle

T491B474M035AT tantalum capacitors are a type of electrochemical capacitor developed and made from the element tantalum. They have some benefits compared to other capacitors such as a greater capacitance for a given size, a small form and reliability over a wide range of temperatures. They are also very popular with engineers and are widely used in various industrial, automotive and telecom applications.

How T491B474M035AT Tantalum Capacitors Work

T491B474M035AT tantalum capacitors are constructed with two electrodes placed in a tangential-style configuration. The electrodes are composed of a porous anode made of a metal oxide material formed on a tantalum powder core and a cathode which is usually composed of an aluminum film or welded lead frame. The two electrodes are separated by an insulating material, usually a polymer.When the capacitor is being charged, the electrode passes a current and a charge builds up on the metal oxide layer. This charge creates an induced electrical field on the metal oxide layer. As the voltage increases, electrons and protons within the metal oxide form a conductive film. The resulting capacitance created between the two electrodes is what allows the capacitor to store energy.
