Working Principle

The M39003/03-0429/HSD capacitors are based on the principle of electroluminescence; when an electric current is passed through a layer of semiconductive tantalum dioxide, it emits a soft orange light. This light is then used to reduce the size and volume of the capacitor, while ensuring it retains a high level of performance even under extreme environmental conditions.

The housing of the capacitor consists of a solid metal plate with a layer of electrolyte sandwiched between the metal plates. The electrolyte in the circuit acts as an insulator and conductor, allowing electrons to flow from one metal plate to another. When an electrical signal is applied to the capacitor, current flows from the positive to the negative plate, which in turn creates a positive charge on the positive plate, and a negative charge on the negative plate. As a result, a strong force of attraction is created between the two plates, which leads to a current flowing across the dielectric.

M39003/03-0429/HSD capacitors have been designed to be self-healing; this means they have the ability to not only recover from overvoltages and high temperatures, but also offer superior protection against lightning and power transients. They are also highly resistant to mechanical shock, moisture, and temperature extremes.

The M39003/03-0429/HSD capacitors offer extreme operating parameters with an excellent temperature performance and long shelf life. They also offer an enhanced voltage rating with improved reliability and superior capacitance stability.

Conclusion

M39003/03-0429/HSD capacitors are ideal for high-performance applications. With their enhanced power handling capability, improved volumetric efficiency, and self-healing properties, they provide reliability even under the most extreme environmental conditions. These capacitors also offer robust construction and long service life, making them a great choice for a wide range of military and industrial applications.
