Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, such as the 100YXH27MEFC8X11.5, are essential components in many circuits. These capacitors store electrical energy in a form of static electricity and are much smaller and lighter than older alternatives such as paper and lead capacitors. Aluminum electrolytic capacitors are also able to handle significantly higher capacitance per volume than older technologies, making them perfect for use in electronics that require a high amount of capacitance in a small space.

The main component of an aluminum electrolytic capacitor is its aluminum oxide layer. This layer of aluminum oxide acts as an insulator and separates two conductive surfaces, providing a strong capacitance. The capacitance — measured in farads — is a measure of how much electric charge the capacitor can store. Different capacitors have different capacitance values, depending on the size and construction of the capacitor itself.

The 100YXH27MEFC8X11.5 aluminum electrolytic capacitor is an example of an axial-type capacitor. It has a cylindrical body with two leads extending out of either end. Inside, between the two metal leads, is a roll of foil that forms the capacitor’s electrodes and core. The roll is soaked in an electrolyte liquid and covered with an aluminum oxide layer. This type of capacitor is a common type of non-polarized capacitor, meaning the two leads do not determine polarity.

This type of aluminum electrolytic capacitor is typically used in applications that require high capacitance in a small space, such as amplifiers, power supplies, and linear and switching circuits. The 100YXH27MEFC8X11.5 can also be used in audio and radio frequency filters, decoupling circuits, and noise suppression circuits. Its operating temperature range is from -55°C to +125°C, making it a versatile component for many applications.

The working principle of all aluminum electrolytic capacitors is based on Faraday\'s law of electrolysis. This law states that when a voltage is applied to a circuit containing electrolyte, the current passing through the electrolyte will depend on the electrolyte\'s resistance. In an aluminum electrolytic capacitor, this voltage causes a reaction in the electrolyte solution, which in turn produces ions that are deposited on the aluminum oxide layer. These ions form an electricdouble layer between the two metal electrodes, which creates the capacitor\'s electrostatic field and stores energy.

The 100YXH27MEFC8X11.5 aluminum electrolytic capacitor has a rated capacitance of 8.0µF at a rated voltage of 400V AC, meaning it can store 8µF worth of electrical charge at 400V AC. When the applied voltage is above or below this rated voltage, the capacitor\'s capacitance will also change accordingly. Additionally, this capacitor has a rated leakage current of 25µA and an Impedance of ≤20MΩ at 1 kHz, making it an ideal choice for many circuit designs.
