Aluminum electrolytic capacitors (AECs) are the most widely used type of capacitor in the world. They are used in a variety of industrial, scientific, and consumer applications. AECs are constructed with an anode, cathode, and electrolyte. The anode is a thin layer of aluminum foil, usually anodized or plated with a layer of oxide. The cathode is typically made of aluminum foil, but can also be made of other materials such as tin, zinc, or copper. The electrolyte, which acts as the medium to transport electrons, is typically a solution of potassium hydroxide in water. The 397LBB350M2ED is a long-life, low ESR, non-polarized aluminum electrolytic capacitor. It is a radial-lead, cylindrical-shaped capacitor with 7.3mm diameter and 15mm length. It has a rated voltage of 350VDC and capacitance of 220uF. The 397LBB350M2ED features an extended lifetime up to 10000 hours at full rated voltage, low ESR, very low temperature coefficient and high ripple current tolerance. The 397LBB350M2ED is primarily used in applications requiring high space efficiency and a compact, long-life capacitor, such as personal computer motherboards and power supplies, gaming consoles, digital TV power supplies, medical imaging monitors, security and surveillance systems, industrial power supplies, and various consumer electronics. This capacitor\'s extended lifetime and high ripple current tolerance makes it ideal for applications that require high reliability and long-term stability. The working principle of the 397LBB350M2ED is based on the principle of charge storage. When the capacitor is connected to a DC voltage source, electrons are drawn from one terminal to the other, resulting in an electrical charge separation across the capacitor plates. This charge separation creates an electric field between the two plates, which then stores the electrical charge and produces a capacitive current. The capacitive current then passes through the capacitor, supplying its current to the electrical circuit. The 397LBB350M2ED also features self-healing, which is a self-protective characteristic that enables it to repair itself in the event of an excessive surge. Self-healing helps to prevent the capacitor from failing due to an overload in the electrical system. Over time, the self-healing effect of the capacitor decreases in effectiveness, which is why capacitors will often need to be replaced after a certain amount of time or when their performance begins to degrade. Overall, the 397LBB350M2ED is a versatile aluminum electrolytic capacitor that is ideal for applications that require high reliability and long-term stability. Its extended lifetime, low ESR, and high ripple current tolerance make it an excellent choice for a variety of consumer, industrial, and scientific applications.
