Aluminum electrolytic capacitors are passive electronic components made up of two aluminum foils with an electrolyte-infused paper layer between the two foils. The aluminum foil acts as the positive electrode and has a layer of insulating oxide on it. The other aluminum foil serves as the negative electrode and is used as the conductive surface. The electrolyte-infused paper layer serves as the dielectric material and also contains chemicals that allow the transfer of electrical charge from one foil to the other. The construction of aluminum electrolytic capacitors makes them ideal for applications that require high current handling, stability, reliability, and long life. It is also worth mentioning that aluminum electrolytic capacitors are relatively low cost and easy to manufacture, making them popular in electronics applications.

B41851B9476M000 is a specific type of aluminum electrolytic capacitor manufactured by EPCOS. It is typically used in applications that require high-temperature reliability, high-stability performance, and high-accuracy components. The construction of this model includes a metallized polyphenylene oxide film as the dielectric material, a polyester sleeve, and a conductive element composed of aluminum oxide as the cathode. Additionally, the capacitor is surrounded by a polypropylene case, which helps to protect the capacitor from mechanical damage.

In addition, B41851B9476M000 is often used in industrial and commercial applications, such as motor drives, welding machines, security systems, and lighting systems. It is also widely used in consumer electronics applications, such as televisions and computers.

The working principle of an aluminum electrolytic capacitor is based on the Faraday law of electrolysis. In a typical aluminum electrolytic capacitor, the anode (positive) electrode is made up of an aluminum foil, while the cathode (negative) electrode is made up of insulating aluminum oxide. When the capacitor is connected to a power supply, the anode foil is electrochemically oxidized to form an insulating layer of aluminum oxide. Electrons are released from the aluminum and migrate to the aluminum oxide, forming an electron-poor region on the anode. The positive ions in the electrolyte migrate from the cathode to the anode and combine with these electrons to form a layer of aluminum oxide. In effect, the aluminum oxide effectively insulates the anode from the cathode, thus creating the capacitance. Additionally, the current flow between the anode and cathode is regulated by the thickness of the insulating oxide layer and the number of electrons released from the anode.

In summary, B41851B9476M000 is a type of aluminum electrolytic capacitor manufactured by EPCOS. This capacitor is specifically designed to withstand high temperatures and to provide high-accuracy performance.
