Working Principle

The M39003/03-0473H capacitor model works by storing an electrical charge between two conductive plates, known as electrodes. When an electrical signal is applied between the two plates, an electrical field builds up, allowing the capacitor to store energy. The amount of energy stored in the capacitor is determined by the capacitance, which is determined by the area of the plates and the distance between them.

The M39003/03-0473H capacitor model is designed to balance electrical properties between the two plates. A dielectric material, such as tantalum, is applied to the center of the plates, creating a barrier between them. This prevents the electrical charges from flowing freely between the plates, and helps maintain a constant voltage between them.

The dielectric material also helps to minimize capacitor leakage. As current is applied to the device, and electrical charges build up on the plates, the dielectric border can help prevent these charges from leaking out, reducing power loss and ensuring more consistent performance.

Conclusion

The M39003/03-0473H tantalum capacitor model is designed for use in a wide range of defense and professional audio applications, and is ideal for use in low-power circuits. Its solid-polymer cathode and tantalum core provide superior durability, and its low ESR rating ensures better performance in challenging environments. The dielectric material used in the capacitor helps to reduce leakage and power loss, ensuring consistent performance.
