Aluminum electrolytic capacitors are capacitors that use an aluminum foil covered with an oxide layer as electrodes for a capacitor. The electrolyte for this type of capacitor is an inert electrolyte, usually aqueous solution of sulfuric acid or organic carboxylic acids (typically ethylene glycol). The aluminum foil is conductive and the oxide has a very high dielectric constant, providing a large capacitance in a very small space.

The SEK3R3M160ST aluminum electrolytic capacitor is designed to meet the specific needs of industrial, military and aerospace applications in terms of reliability, long life, high temperature performance and vibration resistance. It is constructed with a patented design that provides a very low ESR and CTE, plus it can operate at temperatures as low as -55°C to +125° C.

The SEK3R3M160ST aluminum electrolytic capacitor provides superior performance compared to polyester and ceramic capacitor types. The unique design of the aluminum electrolytic capacitor allows it to act as a digital filter in high temperature applications, providing higher levels of accuracy and reliability.

The working principle of the SEK3R3M160ST aluminum electrolytic capacitor is based on the electrolyte electrolysis. In this process, an electrical current passes through an electrolyte, which is typically sulfuric acid or an inert organic compound such as ethylene glycol, to form a positively charged ion and a negatively charged ion. The positively charged ions are attracted to the negative surface of the aluminum foil, while the negatively charged ions are attracted to the positive surface. This creates a charge balance between the two surfaces, resulting in a capacitance.

The SEK3R3M160ST aluminum electrolytic capacitor has a high capacitance value thanks to the high dielectric constant of aluminum oxide. Additionally, the electrolyte serves as an insulator, preventing any electrical shorts from occurring between the two electrodes. The large capacitance of the SEK3R3M160ST makes it ideal for a wide variety of applications, including high temperature applications, power systems, and military and aerospace applications.

The SEK3R3M160ST aluminum electrolytic capacitor is widely used in automotive, industrial, military and aerospace applications for its reliability, high temperature operation, low ESR, and very low CTE. It is also used in power systems, digital filters, and other applications that require a large capacitance value in a small space. The design of the capacitor ensures long life and reliability, allowing for reliable operation even in harsh environments.
