Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that utilizes an electrolyte to form the dielectric. These are the most popular and commonly used capacitors in electronic circuits, thanks to their large capacitance and low cost.

They are relatively simple in design and construction, consisting of a thin aluminum foil electrode, separated by a paper-based dielectric, then rolled up into a cylindrical package. An electrolyte is poured into the cylinder and the voice coil is sealed in using a screw cap or solder. The electrolyte serves both an electrical purpose, forming an electrolytic bridge between the two electrodes, and a mechanical purpose, providing pressure to keep the electrodes from shorting.

The most common application for aluminum electrolytic capacitors is for the smoothing of a signal or ripple, in power supplies and other types of circuits. The capacitors can act as a storage device, supplying or filtering additional current when needed. In addition, aluminum electrolytic capacitors are used as filters to reduce noise in audio circuits. They are also frequently used for filtering high frequency signals in communication devices.

The USR1V4R7MDD aluminum electrolytic capacitor is particularly suited for power supplies and DC-DC converters. It is robust, reliable and easy to use, with no extra mounting hardware required.

The working principle behind the USR1V4R7MDD is fairly straightforward. When a positive voltage is applied across the two electrodes, the aluminum foil becomes covered with an oxide film that acts as an insulating layer. As the voltage is increased further, the oxide layer becomes thinner until it eventually breaks down, allowing for current to flow between the two electrodes. This is known as an "electrolytic effect". The oxide layer is continuously replenished when the device is powered on, hence it is deemed as an "electrolytic capacitor".

The USR1V4R7MDD aluminum electrolytic capacitor offers excellent performance with a maximum working voltage of 4.7 VDC, a low ESR of 0.45 Ω at 20°C, and a high ripple current rating of 6.4 A.

The device is RoHS compliant, low EMI, and features a low self-discharge rate, making it suitable for a wide range of applications in consumer electronics, automotive, medical, industrial and telecom products. The aluminum electrolytic capacitor can operate in temperatures ranging from -40° to +85° C.

In summary, the USR1V4R7MDD aluminum electrolytic capacitor is a robust, reliable and easy to use device, offering excellent performance and a wide range of applications.
