Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are the most common type of capacitors in the world. They consist of two aluminum plates separated by an electrolytic paper, a dielectric material which holds a charge when placed between two conducting electrodes. The dielectric layer can be made of paper, plastic, or any other suitable material, and is usually coated with a thin layer of metal or graphite for additional insulation.The B43455A9478M3 aluminum electrolytic capacitor is a radial-lead, non-polarized aluminum electrolytic capacitor with a large temperature operating range and a broad range of voltage ratings. It is designed for use in high temperature, low-voltage, or high-voltage circuit applications. This capacitor has a standard 7.3mm x 9.5mm x 33mm overall size and is designed to meet Airbus C-14-10 or UL/EN/IEC-61039 requirements. It has a wide -40°C to 105°C temperature operating range and a 12 to 25V rated voltage range. The capacitor insulation rating is 5.5kΩ at 20°C for a minimum of one minute.The working principle of an aluminum electrolytic capacitor is based on an electrochemical reaction between the two plates. The cathode, or negative plate, is made of aluminum foil with a thin film of manganese dioxide coating, which acts as an electrolyte. The positive plate, or anode, is made of aluminum foil or metalized plastic film. When an electric current is applied to the capacitor, a chemical reaction takes place, causing ions from the electrolyte to travel to the anode, forming a thin layer of aluminum oxide or a ‘dielectric’ on the anode. This layer acts as an insulator between the two plates, creating a separation that allows the capacitor to store a charge. As the electric current is removed, the charge remains stored in the capacitor until the current is reapplied.The B43455A9478M3 aluminum electrolytic capacitor has a wide range of applications, such as power supply circuits, LCD display circuits, automotive and military electronics, and telecommunications. The capacitor\'s unique combination of high temperature, low-voltage, and high-voltage range makes it an ideal choice for many applications. Additionally, its broad temperature operating range of -40°C to 105°C makes it suitable for use in extreme temperature conditions. The capacitor is also UL/EN/IEC-compliant and contains RoHS-compliant components.In summary, the B43455A9478M3 aluminum electrolytic capacitor is a non-polarized radial-lead capacitor with a wide temperature operating range and a broad range of voltage ratings. Its large temperature operating range and broad range of voltage ratings make it an ideal choice for many applications. The working principle of the capacitor is based on an electrochemical reaction between the two plates, which creates a dielectric layer on the anode, allowing it to store a charge. The capacitor is compliant with UL/EN/IEC and RoHS standards, which ensures its reliability and safety.
