Tantalum capacitors have a variety of uses, including in general-purpose and specialized circuits. The M39003/03-0263/TR is a type of surface-mount tantalum capacitor that is designed for high-temperature operations. Its application field and working principle are described in this article.

Tantalum capacitors, also known as electrically polarized capacitors, use an oxide layer as the dielectric material to store electrical charge. The oxide layer is usually formed by an electrolytic process that utilizes a solution comprised of tantalum and oxide components. This process forms a thin film of tantalum dioxide on the plates of the capacitor, which provides the necessary electrical insulation between the plates.

Surface-mount tantalum capacitors such as the M39003/03-0263/TR are small in size yet highly reliable. They have a much higher temperature coefficient than conventional tantalum capacitors, making them ideal for use in circuits where high temperatures might be encountered. Furthermore, since these capacitors are surface-mounted, they take up much less space than conventional tantalum capacitors, making them well-suited for space-conscious circuits.

Being an electrolytic capacitor, the M39003/03-0263/TR also has a polarity, meaning that it must be connected to the power source in the correct orientation for maximum efficiency. Moreover, it requires a steady supply of electrical current for full functionality. This capacitor is commonly used in electronic circuits that need a reliable power source, such as computer motherboards or other power circuits.

The M39003/03-0263/TR is rated at 50 V and 2.2 μF, making it suitable for use in a wide range of applications. Its operating temperature can range from -65°C to 125°C, and its endurance rating is 2.5A at 85°C. For this reason, it is well-suited for high-temperature applications such as automotive and industrial circuits. It also complies with the requirements of the European Union\'s RoHS directive for hazardous materials.

In summary, the M39003/03-0263/TR is a type of surface-mount tantalum capacitor designed for high-temperature operations. Due to its small size and high temperature coefficient, it is well-suited for use in space-restricted and high-temperature circuits, such as automotive, industrial, and computer circuits. It complies with the RoHS directive and has a range of ratings, making it suitable for a variety of applications.
