Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a type of capacitor that uses an electrochemical process to achieve higher levels of capacitance simply and efficiently. It uses two aluminum foils covered by a dielectric layer made of an aluminum oxide film. The electrolytic process creates a high voltage electrostatic field to polarize the oxide film and increase its dielectric capability. An aluminum electrolytic capacitor, as opposed to other types of capacitors, uses the opposite orientation for the two electrodes to achieve a higher level of capacitance with a smaller amount of surface area within the same size component.

LLS1H682MELA Application Fields and Working Principle

The LLS1H682MELA is a polarized aluminum electrolytic capacitor. It has a operating temperature running from -40°C to +85°C, rated voltage of 25V, and capacitance value of 68,000μF. This capacitor is used for filtering and smoothing the mains voltage, and their characteristics are optimized for applications such as high temperature DC motors, frequency converters, welding generators and other devices for voltage noise reduction.

The working principle of the aluminum electrolytic capacitor is based on the fact that the oxide film, the electrolyte and the two metals are subjected to the voltage from the external electric field, and the electric field changes the charge state on the edges of the electrode and the oxide film, thus establishing an electrical dissolution/precipitation equilibrium. This generates the negative connection between each electrode, which is stored in the capacitor. The electric double-layers which are formed respectively at the interface of the two electrodes allow the exchange current to flow to the opposing electrode and the entire reverse current is blocked, forming a capacitor.

The LLS1H682MELA aluminum electrolytic capacitor is most suitable for high temperature and high voltage operation with high reliability, and for low impedance and low ESR application. It is used widely in converters and electrical machines.
