Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of polarized capacitor which makes use of an electrolyte to achieve a larger capacitance than other capacitor types. They are widely used in many applications such as power supplies, signal processing and audio applications. Aluminum electrolytic capacitors are constructed from two aluminum foils with oxide layers, terminal leads, and separator paper saturated with electrolyte. The B41693A227Q7 Aluminum Electrolytic Capacitor is an example of such a capacitor.

Application Field

The B41693A227Q7 Aluminum Electrolytic Capacitor is widely used in decoupling applications to maintain a proper power supply within a circuit. This capacitor helps to reduce noise and AC ripple on the power source. It is also used in high frequency applications like switching power supplies. As well, this capacitor is also used in filter applications in which AC voltage appears at frequencies (such as the mains frequency) which are too low to be passed by a power supply, but too high to be filtered by a normal capacitor without an electrolyte.

Working Principle

The working principle of an Aluminum Electrolytic Capacitor follows the conventional capacitor construction. The capacitor is composed of two aluminum electro-plates surrounded with an insulating material (dielectric) such as an oxidized film, which acts as the dielectric layer for storing energy. The dielectric in turn is able to support the charge necessary to function as a capacitor by allowing it to diffuse from one plate to the other.Electrolyte is then added between the two plates to allow current to flow through the electrons in the metal plates instead of through the insulating material. These electrons, once they reach the other plate, create a charge which acts like a static electricity source, only regulated by the voltage of the battery. So, when a voltage is applied to the capacitor, the electrolyte will allow the charge on one plate to be drawn away to the other plate, allowing the capacitor to have a main job of storing electric energy.

Conclusion

The B41693A227Q7 Aluminum Electrolytic Capacitor is a widely used and reliable capacitor perfect for decoupling applications. It is constructed from two aluminum foils with oxide layers, terminal leads, and separator paper saturated with electrolyte, making it a great capacitor for audio applications as well as high frequency filter applications. The working principle of an Aluminum Electrolytic Capacitor follows a conventional construction, and the capacitor has a main job of storing electric energy.
