Tantalum Capacitors: M39003/01-5614/TR Application Field and Working Principle

Tantalum capacitors are high-capacity, non-polarized capacitor components which are used in numerous applications and products such as consumer electronics, automotive, industrial, medical, and military. The M39003/01-5614/TR Capacitors are a part of the Military-Standard (MIL-STD) series of tantalum capacitors, specially designed for use in the military and aerospace industries. This series boasts high-reliability, high-temperature, and low-loss components.

The M39003/01-5614/TR Capacitors offer a broad range of capacitance values, ranging from 0.015μF to 0.165μF, with voltage ratings of 2V, 4V, 6V, 10V, 15V, 25V, 35V, 50V, 80V, 100V, 150V, and 200V. These capacitors are built with a solid tantalum core and a hermetically sealed manganese dioxide dielectric that offers high stability with no significant capacitance change over time. They also feature a long shelf life, and are capable of withstanding up to 180°C peak temperature.

Application Fields

M39003/01-5614/TR Capacitors are widely used in Bias networks, timer/oscillator circuits, pulse networks, high-voltage supplies, and by-pass and decoupling circuits in the military and aerospace industries. They are also used in DC blocking, AC and DC filtering, and timing circuits.

These capacitors have special applications in low-noise systems such as microwave radio and measurement, and communication equipment. They can also be used in regulated power supplies, switcher designs, and high-frequency applications, due to their low ESR and voltage derating characteristics.

Working Principle of Tantalum Capacitors

Tantalum capacitors are based on the same principle as other types of electrical components, such as electrolytic capacitors. When current flows through the terminal of the capacitor, a dielectric material called tantalum pentoxide (Ta2O5) forms a dielectric between the two metal plates, creating an electric field. The electric field stores energy, just like other capacitors.

The main difference between a tantalum capacitor and other types of capacitors is the type of dielectric used in its construction. A tantalum capacitor uses a "solid" rather than "in liquid" dielectric, allowing for a much greater capacitance in a much smaller package.

The amount of charge that a capacitor can store is determined by its surface area, the distance between the plates, and the type of dielectric material used. The higher the capacitance, the greater the amount of electric charge the capacitor can store. A tantalum capacitor can store a much greater amount of electrical charge than other types of capacitors, hence their great popularity in industries such as military and aerospace.

Conclusion

The M39003/01-5614/TR Capacitors are a part of the MIL-STD series of capacitors, designed specifically for use in military and aerospace. The series offers various capacitance values and voltage ratings, and is built with a hermetically sealed manganese dioxide dielectric that offers excellent stability and a long shelf life. These capacitors are used in a variety of applications, from DC blocking and AC and DC filtering to low-noise systems and high-voltage supplies. The working principle of these capacitors is based on the same principle as other types of electrical components, but with a much greater capacitance.
