Tantalum capacitors are an important component of modern electrical and electronic circuits. They are used in a variety of applications, ranging from power supplies to consumer electronics, and are available in a range of sizes, ratings, and capacitance values. The M39003/03-3079/TR is a popular type of tantalum capacitor. This article will explain the application field and working principle of the M39003/03-3079/TR.

Construction and Composition

The M39003/03-3079/TR is a type of surface mount tantalum capacitor. It has a rectangular or cylindrical shape and is typically constructed as a single or double layer capacitor. The capacitor consists of a tantalum anode and cathode, surrounded by a dielectric layer. The dielectric layer can be constructed from organic polymers, ceramic materials, or some combination of materials.

The anode and cathode are connected to two separate electrical leads made of metal or plastic. The anode and cathode can also be connected with adhesive, in order to ensure a secure connection. The metal leads are typically interfaced with a soldering or crimping process, which is used to securely attach the leads to an electrical substrate.

Application Field and Working Principle

The M39003/03-3079/TR is primarily used in applications where a high capacitance value is required. It is commonly used in power supplies, automotive, and consumer electronic circuits, and can also be used in radio frequency applications. The capacitor is also widely used in military and aerospace applications, due to its reliability and long service life.

The M39003/03-3079/TR has a wide range of working voltages and capacitance values, ranging from 2.5V to 30V, and from 0.47µF to 330µF, respectively. The capacitor also has a very low leakage current and is capable of handling transient current and voltage spikes.

The working principle of a tantalum capacitor is relatively simple. It is based on the principle of charge accumulation, or stored energy. When an electric current is applied to the capacitor, a charge builds up in the anode and cathode. The charge in one plate accumulates and attracts the free electrons in the other plate, thus creating a potential difference between the two plates.

The voltage rating of the capacitor determines the maximum voltage that can be stored in the capacitor. As the voltage increases, the charge stored in the capacitor also increases, up to the point where the voltage reaches its maximum rating. The capacitance value determines how much charge can be stored in the capacitor. The higher the capacitance, the more charge can be stored in the capacitor.

Conclusion

The M39003/03-3079/TR is a type of surface mount tantalum capacitor. It is commonly used in applications where a high capacitance value is needed, such as in consumer electronics, automotive, and military applications. The working principle of the M39003/03-3079/TR is based on the principle of charge accumulation, and it has a wide range of working voltages and capacitance values.
