Tantalum capacitors are a robust, reliable, and highly efficient type of capacitor which use tantalum for the anode of the capacitor. The T540D477M2R5AH8505 is a surface-mountable tantalum capacitor specifically designed for low-profile applications. It is an electrolytic capacitor, meaning it uses an electrolyte as the dielectric. Its construction makes it ideal for use in small and sensitive electronics, such as laptop and cell phone batteries, as well as in industrial and military applications.

The T540D477M2R5AH8505 has a capacitance of 4.7µF, a rated operating temperature between -55°C and +85°C and a maximum DC leakage current of 4.5µA. It also has a voltage rating of 5V and a maximum working voltage of 5V. The physical size is 0.50mmx0.45mm and the weight is 0.2g.

The T540D477M2R5AH8505 is a popular choice for portable electronic devices such as laptops, tablets, and cell phones due to its low profile and high reliability. It is also well suited for use in industrial and military applications, such as computers and radar systems, where its high efficiency and durable construction make it a good choice.

The working principle behind a tantalum capacitor is very simple. An electrolyte, typically a mix of salts and/or acids, such as manganese or sulphate, is used to form a thin layer of dielectric between two electrodes. This layer acts as a barrier that prevents the flow of electric current between them, allowing them to store an electrical charge. As electrical current is applied to the capacitor, a layer of oxide forms on the surface of the electrode, which effectively increases the capacitance of the capacitor.

The oxide layer formed on the surface of the tantalum capacitor allows for its use in high-temperature environments. This makes it well-suited for applications where the components must withstand severe temperature fluctuations, such as in industrial settings. The capacitor also has a long lifespan and can withstand frequent surges in current and voltage. In addition, its low profile makes it a great choice for use in tight spaces.

Tantalum-polymer capacitors are incredibly useful components, and the T540D477M2R5AH8505 is an excellent example. Its low profile, reliability, and high efficiency make it perfect for many industrial, military, and consumer applications. Manufacturers around the world have recognized its advantages and use it in their products to create robust and reliable components.
