Aluminum electrolytic capacitors are a family of capacitors that contain an anode composed of a pure aluminum foil with an etched surface that is uniformly covered with an insulating film, a cathode foil that is in direct contact with the anode, and at least two non-conductive electrolytes. They offer higher capacitance than plastic film capacitors, and are widely used in power supplies, DC-DC converters, and signal conditioning circuits. The 687LBB350M2EG is an aluminum electrolytic capacitor from the 687L series of capacitors produced by Vishay. This capacitor has a 450V DC voltage rating and a capacitance of 220 μF.The 687LBB350M2EG is a bipolar aluminum electrolytic capacitor with two leads. It has a cylindrical, snap-in case, and is rated for an extended operation temperature range from -55°C to +105°C. The 687LBB350M2EG capacitor can be used in applications that require high capacitance in small packages, such as power supplies, DC-DC converters, and signal conditioning circuits. The capacitor is characterized by low ESR, high ripple current capability, and long life.The operation of a capacitor is based on the principle of storing energy in an electrostatic field between two metal plates. The two metal plates, which are electrically insulated from each other, are the anode and the cathode. When a voltage is applied to the capacitor, a current flows through the electrolyte between the plates, and an electric field is created, which creates a space charge in the electrolyte. This creates a potential difference between the two plates, and the voltage across the plates is proportional to the amount of charge stored in the capacitor.Since the 687LBB350M2EG is a bipolar aluminum electrolytic capacitor, its two plates are composed of a pure aluminum foil and air. This capacitor is capable of storing more charge and providing higher capacitance than conventional plastic film capacitors. The etching of the anode gives the 687LBB350M2EG a superior surface area, which increases its charge-holding capacity. The capacitor also has an inserted non-conductive electrolyte between its two plates, which provides greater dielectric strength and stability than a conventional capacitor.The 687LBB350M2EG aluminum electrolytic capacitor from Vishay is a reliable and high-performance component that can operate in temperatures ranging from -55°C to +105°C, and offers long life, low ESR, and high ripple current capability. It is designed for use in power supplies, DC-DC converters, and signal conditioning circuits, and is ideal for applications that require high capacitance in small packages.
