Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most commonly used components in electronic circuits. These are polarized electrochemical capacitors in which electrical energy is stored in the form of an electrolytic solution. They have a cylindrical shape and consists of two electrodes, one is made from an aluminum foil and the other from a porous solid like sintered carbon. A layer of electrolyte separates the two electrodes and the whole assembly is held together by a spacer.

The EDH226M050A9GAA aluminum electrolytic capacitor belongs to the snap-in type of capacitors. It has a rated capacitance of 50µF and a rated voltage of 16V and 25V. This capacitor is typically used in switching power supplies and power line circuits where large currents are handled and low ESR is required. It also features an extended low temperature super capacitor range (-40°C to 105°C) making it well suited for multiple applications.

Working Principle

Aluminum electrolytic capacitors depend on the generation of an electric field provided by a thin coated aluminum oxide layer between two layers of aluminum. The aluminum oxide layer is a dielectric and holds a charge for a long time, even after the power is removed. In other words, this capacitor behaves like an electric battery, storing electricity.

When the capacitor is connected to a power source, electric current flows from the negative terminal of the power source to the capacitor. This current flows through the capacitor and creates an electric field across the dielectric layer of the capacitor. This electric field creates a special "polarized" electrostatic effect, which holds the electrical charge even after the power source is removed.

Application Field

Aluminum electrolytic capacitors are typically used in circuits which require a large voltage rating, and consist of two layers of material with different electrical properties. Some applications in which an aluminum electrolytic capacitor can be used include:

• Power supply circuits
• Switching power supplies
• Power line filters and suppression circuits
• Clocks, timers, and amplifiers
• Noise filtering and decoupling in automotive electronics
• RF interference suppression
• RFID systems
