M39003/01-5422 Application field and working principle

Tantalum capacitors are devices that store energy in the form of an electric field. They are made out of two continuous plates of tantalum metal separated by a dielectric material. One plate is connected to a positive potential and the other to a negative one, and as current is applied, electrons flow between the two plates, creating a potential difference across the plates. The M39003/01-5422 capacitor is a surface mounted chip-type capacitor that is designed for use in military and aerospace grade circuit boards. It is often used in applications such as signal conditioning, power management, and radio frequency communications.

Structure

The M39003/01-5422 is constructed with a tantalum metal case, which contains a dielectric layer followed by a protective layer of silver plating. The device is then wirebonded in place by a combination of gold and refractory wires. The capacitor is then sealed with a protective cover (usually an epoxy resin). This entire assembly is then soldered onto the bottom side of the circuit board.

Working Principle

The M39003/01-5422 is based on the principle of electrostatic storage. In this device, energy is stored in the form of an electric field between two conducting plates. The electric field is generated by the application of a voltage across the two metal plates. This electric field creates a dielectric between the plates, which stores the energy. As current flows through the device, electrons flow between the two plates, creating a potential difference between the plates. This potential difference, called the capacitance, is measure in farads (F).

Application

The M39003/01-5422 is commonly used in military and aerospace grade circuit boards due to its robust construction and high reliability. The capacitor is often used in applications such as signal conditioning, power management, and radio frequency communications. It is also well-suited for use in applications that require high temperatures, vibration resistance, and low-ESR (Equivalent Series Resistance). The capacitor\'s low ESR makes it a good choice for high-frequency, fast-switching applications.

Conclusion

The M39003/01-5422 tantalum capacitor is a surface mounted chip-type capacitor that is well-suited for use in high-temperature, vibration-resistant, and fast-switching applications. The capacitor is based on the principle of electrostatic storage, where energy is stored in the form of an electric field between two conducting plates. The M39003/01-5422 is ideal for use in applications such as signal conditioning, power management, and radio frequency communications.
