Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized electrolytic capacitors whose anode electrode is made of a pure aluminum foil with an etched surface. The aluminum foil acts as the anode of the capacitor, hence the name aluminum electrolytic capacitor. The non-solid electrolyte, which acts as the cathode, is absorbed in paper or plastic separator and contacts with aluminum foil surface to form the electric double layer. Aluminum electrolytic capacitors are usually used in power applications such as on-board power supplies, motor starters, and motor drives. These capacitors require a positive voltage to be applied to the anode and the appropriate negative voltage to be applied to the cathode.

EEU-FR1J470B Application Field and Working Principle

The EEU-FR1J470B is an aluminum electrolytic capacitor from Panasonic. It has a capacitance of 47uF and a voltage rating of 250VAC, which makes it suitable for a variety of power applications. It has a maximum ripple current rating of 6.8A and an operating temperature range of -40 to +105C. The EEU-FR1J470B is a low-cost, long-life capacitor that is widely used in switching power supplies, motor starters, and motor drives.

The working principle of the EEU-FR1J470B lies in the fact that it is an electrolytic capacitor. This means that it is composed of two metal plates, usually aluminum and tantalum, separated by a non-solid electrolyte. When a voltage is applied across the capacitor, the electrolyte allows charge to flow between the plates, creating an electric double layer and creating a capacitance. This capacitance is measured in Farads (F) and is determined by the area of the electrodes and the distance between them. The EEU-FR1J470B has a capacitance of 47uF, meaning that it has a capacitance of 47 x 10^-6 Farads.

When a voltage is applied, the electric double layer stores charge and allows a current to flow through the capacitor. This current is known as the ripple current and the EEU-FR1J470B is rated for up to 6.8A, meaning it is suitable for a variety of power applications. The voltage rating of the EEU-FR1J470B is 250VAC, which means it is designed to handle a maximum AC voltage of 250V.

The EEU-FR1J470B is an aluminum electrolytic capacitor that is well-suited for a variety of power applications. Its high capacitance and ripple current rating make it suitable for switching power supplies, motor starters, and motor drives and its temperature range means that it can reliably handle applications with a wide variety of temperature fluctuations. So if you are looking for a reliable, low-cost, long-life capacitor, the EEU-FR1J470B is worth a look.
