Aluminum Electrolytic Capacitors are widely used in electronics circuits. The EET-ED2W391EA series is a type of aluminum electrolytic capacitor, which is ideal for its application field and working principle.

The EET-ED2W391EA aluminum electrolytic capacitor is a two-terminal semiconductor device consisting of an anode and a cathode. The anode is made of pure aluminum, which is slightly etched to form an oxide layer. The oxide layer, called a dielectric layer, is a passive layer that prevents the flow of electrons between the electrodes and also acts as an ideal capacitor plate. The cathode is composed of a wire that connects to the capacitor’s body, and then to the circuit. The capacitor’s body is made of an insulated material such as a plastic or epoxy.

The EET-ED2W391EA capacitor mainly features a high rated voltage of up to 400V, a high temperature range from -55℃ to +105℃, and an extremely low ESR, with values ranging between 0.3 Ohm and 0.9 Ohm. These features make it suitable for a variety of applications, such as square wave conversion circuits, smoothing circuits, surge absorbers, and low-pass filters. It can also be used in other different fields, such as high-frequency switching circuits, power supplies, converters, and high-tension circuits.

The EET-ED2W391EA aluminum electrolytic capacitor is a polarized device, and the anode is always connected to the positive terminal, while the cathode is always connected to the negative terminal. The working principle of an aluminum electrolytic capacitor is the same as that of a general electrolytic capacitor. When connected to a DC voltage source, the anode attracts positive ions from the electrolyte and the cathode attracts negative ions. This causes an electric field across the capacitor, thus forming an electric double layer between the two plates.

The capacitance of EET-ED2W391EA aluminum electrolytic capacitor is determined by the geometric surface area of the two plates and the thickness of the dielectric layer in between them. When connected in circuit, a capacitive reactance is produced which produces a certain reactance between the two electrodes, thus reducing the flow of electric current across them. It also acts as a low-pass filter, allowing only high-frequency components to pass while blocking low-frequency components.

The EET-ED2W391EA capacitor is available in various sizes and shapes, such as miniaturized, 2220, 6.3mm, and 10mm. These capacitors are stable under large AC current conditions and are capable of operating up to 400V DC and 250V AC. Its excellent frequency characteristics and low impedances make them suitable for use in a wide range of high-frequency applications.

In summary, the EET-ED2W391EA aluminum electrolytic capacitor is an excellent choice for many applications and fields, thanks to its wide temperature range, high rated voltage, and low ESR. Its design and construction provide good durability and reliability, making it suitable for a variety of operational and environmental conditions.
