Tantalum capacitors are a type of electrolytic capacitors which consist of an encased block of tantalum powder covered in a thin oxide film. The oxide layer acts as an insulating layer between the anode and cathode and enables the capacitor to store electrical charge. The oxide layer is formed on the surface of the tantalum powder when an anode and cathode is built and the tantalum is charged with an electrical current. The anode and cathode then become the two plates of the capacitor.

The T491X476M025AT is a surface mount tantalum capacitor manufactured by Vishay. It is an A case capacitor made of MnO₂ dielectric material and with a 4 Volts maximum working voltage. This type of capacitor has a wide range of applications in any kind of electronic circuit. It can be used in the construction of power supplies, filters, amplifiers, switches, and motors. They are also used to reduce voltage ripple in power supplies and reduce noise emitted from circuits.

The T491X476M025AT works on the principle of electrochemical double-layer capacitance. When a voltage is applied to the terminals of the capacitor, an electrical charge is stored in the dielectric material. This charge accumulates between the two plates of the capacitor, forming an electric double layer. This double-layer capacitance is responsible for the capacitors’ ability to store electrical energy.

The T491X476M025AT is also a non-polar capacitor which means it can be connected in either direction without any loss of performance. This makes it ideal for use in a wide range of electronic circuits, including power supplies, audio amplifiers, radio receivers, and light dimmers.

The T491X476M025AT has a maximum working voltage of 4 Volts and a capacitance of 47µF. It also has low leakage current, low ESR (Equivalent Series Resistance), and low DF (Dissipation Factor). This makes it an ideal choice for many types of applications.

The T491X476M025AT tantalum capacitor is a reliable and efficient component for building any kind of electronic circuit. Its wide range of applications makes it a popular choice for many engineers. With its low voltage, high capacitance and low leakage current, it is an optimal choice for any kind of electrical application.
