Aluminum electrolytic capacitors are capacitors commonly used in electronic circuits. They are composed of two aluminum foil plates with a deposited layer of insulating aluminum oxide between them. The aluminum oxide provides an electrical break between the two plates. The plates are also with a paper insert to stabilize, align and separate the plates.EEA-GA1HR47B is an aluminum electrolytic capacitor manufactured by EPCOS. It is a non-solid aluminum electrolytic capacitor and is used mainly in medium to high voltage power supplies and other industrial applications. It is constructed of two aluminum foil plates with a deposit of aluminum oxide between them. The electrical properties of the capacitor depend on the thickness of the aluminum oxide layer and the properties of the electrolyte solution used.The working principle of the EEA-GA1HR47B is based on the phenomenon of dielectric polarization in electrolytic capacitors. When an electric field is applied across the two aluminum foil plates, the electrons in the aluminum oxide layer are re-arranged according to the electric field and produce an electric dipole in the aluminum oxide. This dipole produces an electrical resistance in the aluminum oxide which limits the current flowing through it and hence the capacitor.The EEA-GA1HR47B has several advantages over other types of aluminum electrolytic capacitors. It has a high temperature rating of up to 145 degrees Celsius and a low impedance of less than 10 milli-ohm. The capacitor also has an excellent ripple current and peak current capability due to its low equivalent series resistance. The aluminum oxide layer in the capacitor has extremely good mechanical strength which helps it to endure harsh working conditions and vibration. Lastly, the capacitor has UL94V-0 flame retardant certification allowing it to be used in rugged industrial environments with fire protection requirements.EEA-GA1HR47B capacitors are used in a variety of applications such as in power supply circuits, electric motor drives, inverters, welding machines, air compressors, switching power supplies and medical equipment. They are ideal for applications where reliable power conversion and electrical noise reduction are important. The capacitor is also used in the automotive industry as well as the telecommunications sector.In conclusion, the EEA-GA1HR47B aluminum electrolytic capacitor is a reliable and durable capacitor used in a variety of industrial applications. Its low impedance and high temperature rating make it suitable for use in extreme environmental conditions. The capacitor is also UL94V-0 flame retardant certified making it a safe choice for applications that require fire protection.
