Aluminum electrolytic capacitors, also known as aluminum electrolytes, belong to the category of electrolytic capacitors. They are widely used in many electrical and electronic products and are the most commonly used type of capacitor. The LLS2D681MELZ series aluminum electrolytic capacitors provide high temperature working performance. The two were designed to provide reliable operation in a wide range of temperatures.The specific application field and working principle of the LLS2D681MELZ aluminum electrolytic capacitor can be introduced as follows:The LLS2D681MELZ aluminum electrolytic capacitor is mainly used in high temperature, high voltage and high power applications, such as switch power supplies, automotive electronics, digital cameras, micro controllers and more. It is an axial type capacitor that uses a special electrolyte, either wet or dry, to provide the required electrical parameters. The anode is made of the aluminum foil, which is then formed into a ripple shape, then rolled into a cylinder and stuffed with the electrolyte. There is also a combustible separator, which is a thin insulating paper between the anode and cathode.The working principle of the LLS2D681MELZ aluminum electrolytic capacitor is based on the property of electrical double-layer effect at the metal surface, which is caused by the charge separation of the electrolyte ions. When the plates of metal are connected to the two poles of a voltage source, the metal ions in the electrolyte charge and disconnect according to the applied external electric field.There are two types of electrolyte used in the LLS2D681MELZ aluminum electrolytic capacitors: non-polarized electrolyte and polarized electrolyte. The non-polarized electrolyte is a mixture of organic solvents, anolyte and neutral salts, while the polarized electrolyte comprises of a mixture of organic solvents, anolyte, and a strong base such as potassium hydroxide. The major advantages provided by the aluminum electrolytic capacitor are that it has a large capacitance in a small size, low ESR (equivalent series resistance), low leakage current, and low losses when operated in high temperature.The performance of the LLS2D681MELZ aluminum electrolytic capacitor is determined by its electrolyte, construction and metallization. The electrolyte affects the capacitance, voltage and temperature coefficient, while the construction and metallization affect the size, inductance, mounting size and temperature coefficient. The LLS2D681MELZ series aluminum electrolytic capacitors have been designed to perform in the toughest environment and provide reliable operation and consistent performance even in high temperatures.In short, the LLS2D681MELZ aluminum electrolytic capacitor is an ideal choice for high temperature applications, offering the much needed reliability in extreme temperature conditions. It provides high capacitance, low ESR and low leakage current, making it one of the most suitable types of capacitors for high temperature applications.
