Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are among the most widely used types of capacitors. They are made by coating an aluminum foil with an oxide film, wrapping this foil around a central spacer and then spiralling the foil, forming a two-layer stack. This stack is then impregnated with a liquid electrolyte which is in direct contact with the aluminum oxide and acts as an ion transporter. They range in capacitance from a few microfarads to several thousand microfarads and come in various sizes, and voltages.

LLS2Z681MELZ Application Field and Working Principle

LLS2Z681MELZ is a type of aluminum electrolytic capacitor that is usually used in applications such as general purpose power supplies, computers and other electronic equipment. It has a capacitance value of 681 μF and a rated voltage of 25 VDC. The main principle that makes the capacitor work is that when the anode and cathode plates are charged oppositely, an electric field is created and an electric current flows through them. This current travels through a thin dielectric layer, creating a dielectric polarization, thus storing energy.

The LLS2Z681MELZ capacitor also has a few unique features that make it well-suited for certain application areas. It has an improved leakage current, low ESR, and long life up to 2000 hours. Additionally, its case size is very small compared to its capacitance and rated voltage, making it ideal for applications where space is a critical factor.

In summary, the LLS2Z681MELZ aluminum electrolytic capacitor is a great choice for applications requiring a high voltage and capacitance rating. It is easily obtained, reliable, and has several features that make it suitable for many applications. It is an excellent choice for projects demanding a cost-effective and long-lasting capacitor.
