Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a type of capacitor that utilizes aluminum foil, a gas impermeable paper and an electrolyte solution to store an electrical charge. Aluminum electrolytic capacitors differ from other types of capacitors in that they are able to hold large amounts of energy and can be used across a wide range of frequencies. Their ability to store large amounts of energy makes them ideal for use in electronic circuits where a certain amount of energy is required, such as in oscillators, voltage regulators, radio receivers and switches.

ESMQ100ELL221ME11D Application Field and Working Principle

The ESMQ100ELL221ME11D is a commonly used type of aluminum electrolytic capacitor that is typically used in power multiplying circuits and filtration power supply circuits. It is a Single-Ended Long Life aluminum electrolytic capacitor that is designed to provide higher capacitance in a compact size. It features an operating temperature range of -55 to +105°C and offers an exceptionally long life of up to 3,000 hours under rated working conditions.

The working principle of the ESMQ100ELL221ME11D aluminum electrolytic capacitor is based on the property of aluminum oxide, which is an insulator that is formed on the surface of the aluminum foil. This oxide layer acts as a dielectric, which provides a high capacitance between the two electrodes of the capacitor. The dielectric is charged with a DC voltage, which causes an electric field to develop between the two electrodes. This electric field is responsible for the accumulation of charge of the capacitor, which can be used to store energy.
