Aluminum Electrolytic Capacitors (AECs) are capacitors which use an anode composed of aluminum foil and a porous aluminum oxide electrolytic layer as the dielectric, along with a liquid or solid electrolyte. They are widely used in a variety of consumer, automotive, and industrial electronics applications. One of the most commonly found AECs is the ECA-2DM470B.

The ECA-2DM470B is a radial lead surface mount Aluminum Electrolytic Capacitor. It is a non-polarized capacitor with an industry-standard 2.5V rated voltage. It has a capacitance of 470µF, and a tolerance of ±20%. The ECA-2DM470B is coated with a resistive coating for enhanced voltage holdup, and a long-term stable temperature coefficient. The ECA-2DM470B has a temperature range of -40°C to +85°C and a ripple current of 1.6A.

The ECA-2DM470B is typically used in applications which require a high amount of capacitance in a small package, such as power supplies, digital TVs, game consoles, cellular phones, and audio amplifiers. It can also be used in audio signal processing applications. The ECA-2DM470B provides a low ESR (Equivalent Series Resistance) with low losses and a high capacitance-to-volume ratio.

The working principle of ECA-2DM470B is relatively straightforward. When a voltage is applied to the capacitor, electrons are pulled from the anode into the electrolyte, forming a double-layer of positive and negative ions. This creates an electric field between the two layers, which stores energy. When the voltage is removed, the ions recombine and the stored energy is released. This process can be repeated over and over again, allowing the capacitor to act as a source of energy.

The ECA-2DM470B is highly reliable and is capable of performing thousands of repeated charge and discharge cycles. It has a shelf life of up to 5 years and can withstand extreme temperatures and vibrations. The ECA-2DM470B is a versatile aluminum electrolytic capacitor that provides high capacitance with a low cost.
