Aluminum electrolytic capacitors are a type of component used in electronics to store electrical energy as a capacitor for use in various electronic applications. The ECA-2AM471 aluminum electrolytic capacitor, made by Nichicon Corporation, is a high capacitance, high ripple current, and low ESR (equivalent series resistance) device. It is specifically designed for use in automotive electronics, such as airbag control systems, power steering circuits, and car navigational systems.

An aluminum electrolytic capacitor consists of two aluminum foils, with their surfaces covered in an oxide film. Sandwiched between the two aluminum foils is a liquid electrolyte or ‘moisture-absorbing’ paper. This structure forms a capacitor, and the oxide film is the dielectric of the capacitor. The oxide film is an insulator that allows electrical charge to be stored within the unit.

The ECA-2AM471 aluminum electrolytic capacitor is a radial lead type device that is rated for 105°C (221°F) operation, with a rated voltage of 6.3V, a capacitance of 470μF and an impedance of 1Ω. It has a low ESR (0.2Ω) and can handle up to 5A of ripple current. It has an extended life rating and doesn’t require any dry out time after being soldered. In addition, it has a low dissipation factor, low leakage current, and is RoHS compliant.

The main application field of the ECA-2AM471 aluminum electrolytic capacitor is in automotive electronics. It is used in a variety of automotive applications, such as airbag control systems, power steering systems, and car navigational systems. It can also be used in other electronic applications that require a high capacitance, high ripple current and low ESR capacitor.

The working principle of an aluminum electrolytic capacitor is based on the electrolytic action of the aluminum plate coated with an insulative oxide film. When electrical voltage is applied to the capacitor, charges build up on the insulating oxide film and between the two aluminum plates. This creates a dielectric within the unit that can store electrical charge. The charges stored on the electrode are the capacitive charge, and the oxide film is the dielectric of the capacitor.

Aluminum electrolytic capacitors are ideal for use in applications where a high capacitance and high ripple current are required. The ECA-2AM471 aluminum electrolytic capacitor is a high-quality device that meets these needs and is highly suitable for use in automotive applications.
