Aluminum Electrolytic Capacitors

Medallion capacitors are aluminum electrolytic capacitors used in avionics, aerospace, and other specialized applications requiring lightweight, robust capacitors with superior electrical characteristics, including long life, high capacitance, low equivalent series inductance, and very low leakage current. The USL1V4R7MDD is one such type of capacitor.

Applicatoin field and working principle

The USL1V4R7MDD is available in a variety of diameters and lengths, ranging from 0.4 inches in diameter to 4.7 inches in length, and is rated to operate between -55 and +125 degrees Celsius. It is designed for extreme temperatures, humidity and vibration, and offers excellent volumetric efficiency, dielectric losses, and small size.

The USL1V4R7MDD uses an electrolyte solution to ionize the aluminum foil electrodes and create an electric field. This electric field stores energy and forms the capacitor. The outside case of the capacitor is composed of stainless steel or aluminum thin-film. The rubber diaphragm between the case and the electrical leads ensure a tight seal and reliable compression for the capacitor.

The USL1V4R7MDD is well suited for avionics and aerospace applications, such as components used in navigation and guidance systems, communication systems, and radar systems. Its high capacitance, low ESR, long life, and low leakage make it ideal for stabilizing voltage, storing energy, and creating filter networks.

The USL1V4R7MDD is commonly used in military, medical, and industrial applications as well. Its low leakage and small size make it ideal for battery powered circuits; its high capacitance and low ESR make it well suited for switching circuits and energy storage; and its long life and high temperature rating make it ideal for industrial use.

In summary, the USL1V4R7MDD is a high quality, high performance aluminum electrolytic capacitor designed for extreme environments. Its small size, low leakage, high capacitance, and long life make it an ideal choice for applications that require reliable and cost-effective performance.
