Aluminum electrolytic capacitors, also known as "aluminum capacitors" or "electrolytic capacitors", are the most widely used capacitors in electronic equipment. They are the products of a special forming technology, which are used to store electrical energy. The 475SML100MD8 application field and working principle will be briefly discussed below.The 475SML100MD8 is an ultra-small aluminum-electrolytic capacitor with a high-performance capacitance of 100μF and a resistance to ripple current of 1.3mΩ (at 125°C). This capacitor is suited for general purpose and equipment requiring high performance and reliability.The applications of the 475SML100MD8 are primarily in consumer electronics (computers, TVs, mobile phones, etc.), commercial printing presses, medical electronic devices, power electronics, and automotive bearings.The working principle of aluminum electrolytic capacitors is based on the electrochemical reaction of an electrolyte. The metal foil, which acts as an anode, is pre-treated to promote surface oxide growth. An electrolytic solution is added and the capacitor is filled with an electrolyte, typically an aqueous solution of boric acid or ammonium nitrate. The electrolyte breaks down the oxide barrier and facilitates the transfer of electrons from the anode to the cathode.The positively charged layer of metal oxide separates the anode from the electrolyte solution, forming a dielectric barrier which stores electric charge when a voltage is applied. This electric charge creates a separation between the positive and negative layers, preventing electric current from flowing through the cap.The key advantage of the 475SML100MD8 aluminum electrolytic capacitor is that its design helps reduce the production of heat and thus improve board-level reliability. With its high ripple current capacity, this capacitor can meet the demands of higher operation temperatures, making it suitable for use in a wide range of applications.Overall, the 475SML100MD8 aluminum-electrolytic capacitor provides quiet, low-ESR, and extended performance in consumer electronics, commercial printing, medical devices, and automotive bearings. It also offers excellent thermal stability and efficient cooling properties, making it an ideal choice for high-reliability, high-temperature applications.
