Aluminum Electrolytic Capacitors (ECA) are polarized components, specifically used to store energy or act as filters, buffers, and energy reserves. The main types of ECAs vary between: aluminum electrolytic capacitors with screw terminals (2CM2R2I), high voltage aluminum electrolytic capacitors (2HV2R2I), and aluminum electrolytic snap-in capacitors (2CI2R2I) – with other types of ECAs existing as well.

The 2CM2R2I aluminum electrolytic capacitor is designed with a built-in connection terminal, made from a rugged combination of aluminum, copper, and plated steel. It provides excellent mechanical contact and performance stability. Furthermore, its screw terminals require virtually no effort to assemble onto a board – a feature which makes 2CM2R2I capacitors a popular and cost-effective solution.

2CM2R2I aluminum electrolytic capacitors are typically used as EMI (electromagnetic interference) filters, in audio systems and power supplies, voltage methods, and other electronics applications. 2CM2R2I ECAs also provide increased reliability, high-energy storage, and greater vibration resistance than other types of capacitors.

In terms of technical specifications, 2CM2R2I ECAs are constructed with a bottom lead terminal and an insulated top cover to ensure safety. The capacitors feature capacitances ranging from 0.047uf to 220uf, voltages from 4v to 450v, temperatures from -25°C to 105°C, and life ratings from 2,000 - 7,000 hours.

The working principle of the 2CM2R2I ECA is based on the electric charge stored within the capacitor. When a voltage is applied to the capacitor electrodes, a charge of equal magnitude is accumulated in the dielectric material between the electrodes. When the circuit is disconnected, the charge remains unchanged until the capacitor slowly leaks the stored electric charge. The capacitance achieved is a measure of the amount of electric charge stored.

2CM2R2I ECAs are relatively inexpensive and easily accessible, making them a popular choice for many projects. Their efficient design ensures that 2CM2R2I capacitors can handle more charge than other capacitors, making them suitable for use in a wide variety of applications. Additionally, their plastic cover and embedded vibration-resistant terminal ensure a robust and reliable connection.
