Aluminum electrolytic capacitors are devices that employ electrolyte, aluminum foil, and an activation foil to create a capacitance between two terminals. Electrolytic capacitors have an extremely large capacitance compared to regular ceramic or film capacitors, making them invaluable in applications where space requirements are tight.

The ECA-2WM3R3 is a type of aluminum electrolytic capacitor produced by Panasonic. It is a radial-style capacitor, which means the pins protrude from one side of the capacitor and the mounting is done on a circuit board by soldering. The ECA-2WM3R3 features two pins for easy handling and reliability.

The rated capacitance of the Panasonic ECA-2WM3R3 is 2.2 μF (micro Farads) and the rated voltage is 6.3V. The device has a temperature coefficient of-60 to +125°C, and its operating temperature ranges from -25 to +85°C. Additionally, the ECA-2WM3R3 has excellent surge energy tolerance for reliable high current operation.

The ECA-2WM3R3 capacitors are most commonly used in the electronic circuitry of mobile phones, personal digital assistants, audio equipment and surveillance cameras. Additionally, they are ideal for audio amplifier, power supply, integrated circuit, and automotive application circuits.

The ECA-2WM3R3 capacitors are based on an electrolytic construction, meaning the capacitors rely on an electrolyte between two porous electrodes to store electrical energy. The electrolyte absorbs and stores energy, allowing for an abundant storage capacity. The two electrodes are made from aluminum foil and a dielectric material. When a voltage is applied across the capacitor, the resulting electric field pushes the electrons to travel through the electrolyte, and they accumulate on the negative electrode while the positive electrode releases electrons. This action forms an electric double layer on the electrode surfaces, and it is this double layer that stores the electrical energy.

The ECA-2WM3R3 capacitors are made with a good quality aluminum casing to protect the delicate parts inside. The capacitors have a long working life, with a rated life of 3,000 hours at 85°C. As noted, capacitive life depends on the use environment and operating conditions of the device.

In summary, the Panasonic ECA-2WM3R3 is a radial-style aluminum electrolytic capacitor that offers high capacitance, good surge energy tolerance, and a long rated life. It is designed for use in mobile phones, personal digital assistants, diy audio, surveillance cameras, and other audio amplifier, power supply and automotive application circuits. The ECA-2WM3R3 has a rated capacitance of 2.2 μF and is based on an electrolytic construction, with two aluminum electrodes and an electrolyte between them. The device has a temperature coefficient of-60 to +125°C and an operating temperature range of -25 to +85°C.
