UCD1J330MNL1GS Capacitors

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (also known as electrolytic capacitors, polarized capacitors, or aluminum can capacitors) are capacitors that make use of mobility in an electrolyte and will typically use an aluminum foil substrate to store energy in the form of an electrical double layer. The foil is plated with an organic or inorganic layer that allows for the creation of a thin insulating layer, typically about 5-10 nanometers thick. The part is usually protected from atmosphere or solvent by a jacket of epoxy or glass-fiber reinforced plastic.

Working Principle

UCD1J330MNL1GS aluminum electrolytic capacitors operate using an electrical double layer. The inner electrode of UCD1J330MNL1GS capacitors is typically made from aluminum foil and coated with an oxide layer. The oxide layer has a high dielectric constant, allowing for the creation of an electric double layer on the surface of the aluminum foil. This electric double layer is the origin of the capacitance of the aluminum electrolytic capacitor.

UCD1J330MNL1GS aluminum electrolytic capacitors also contain an electrolyte, usually an aqueous solution of potassium or sodium hydroxide. This electrolyte provides the necessary level of conductivity to ensure that the electrochemical double layer functions properly. The electrolyte also provides the necessary level of electrical insulation that prevents short-circuits between the inner and outer electrodes of the capacitor.

These aluminum electrolytic capacitors also feature a counter-electrode, which is placed in the electrolyte. The counter-electrode helps to ensure that the electrical charges created by the electric double layer are balanced. This ensures that the capacitance of the capacitor remains constant throughout the working life of the device.
