Aluminum Electrolytic Capacitors are electronic components that store energy in the form of an electric field. They are widely used in various fields, from power supplies, audio and video equipment to communication and computer circuit. MAL212317688E3 is a typical example of Aluminum Electrolytic Capacitor.

Applications of MAL212317688E3

MAL212317688E3 is a large capacitance Aluminum Electrolytic Capacitor with a capacitance of 5.0µF and a rated voltage of 200V. It is mainly used in anti-interference filters in the signal processing circuit of consumer electronic products, such as TV, audio, computer and communications equipment. It is also applicable in power supply filter circuits such as AC adapters and audio-frequency amplitude stabilization.

Working Principle of MAL212317688E3

An Aluminum Electrolytic Capacitor consists of two aluminum foils covered by an oxide oxide film acting as the dielectric and a liquid electrolyte as the ESR. The anode aluminum foil is etched with evenly distributed tiny holes to increase the active area and increase capacitance. When an alternating electric field is applied in the capacitor, electric charges will flow in the thin dielectric film and accumulate to create an electric potential and stored electric energy.

The electrolyte serves as the ESR which helps to reduce AC ripple, reduce electric noise and absorb temperature heat. After a certain level of dielectric breakdown voltage is reached, the electrolyte starts to flow and would quickly reduce the capacitance due to the extra resistance applied on the dielectric. That is why it is important to choose the right type of electrolyte upon application fields and environment.
