Aluminum Electrolytic Capacitors: LLG2D152MELA50

Aluminum electrolytic capacitors are electrochemical capacitors that utilize a porous anode licensed with aluminum which is surrounded by a rectifying electrolyte and a cathode foil used as a backing. This enables the device to utilize an electric double-layer between the way of the aluminum anode block and the liquid electrolyte cathode substrate, working as a storage for energy up to 1000 times greater than dielectric film-based capacitors of the same size.

Application Field

LLG2D152MELA50 capacitors are typically chosen for use in a variety of high frequency switching power supplies, voltage regulated power supplies, and other high frequency AC DC applications. Furthermore, due to the wide availability of these capacitors they are often used in a variety of audio and automotive applications.

Working Principle

The operating principle of an aluminum electrolytic capacitor is based on the electrical double-layer or EDL phenomenon. An electric field is generated by the anode/cathode plates that cause the formation of an electrical tunnel via the electrolyte bridge between the two, resulting in a highly conductive dip that stores electrons in the form of a static charge. This static charge then helps maintain a desired voltage state between the two plates which is used in AC, DC and frequency conversion. When current flows across the electrodes, it causes the charges to move and allows for the excessive current to be stored and then returned when the current flow ceases.

Construction

The LLG2D152MELA50 aluminum electrolytic capacitor is composed of a few key parts. The end result of this construction is a highly reliable, long-term, cost effective capacitor. At its simplest, the capacitor is made with an aluminum foil that serves as the anode, and an electrolytic double-layer made of an electrolyte formed between the aluminum foil and a dielectric. The electrolyte chosen must be non-ionizing and conductive. Additionally, there are a cathode foil, metal connections such as pins, and a sealant material used to ensure the proper efficacy of the device in the completed product.

Features & Benefits

The LLG2D152MELA50 aluminum electrolytic cap is designed to provide a wide range of features and benefits. This capacitor offers a very low ESR (equivalent series resistance) and a very high ripple current capability. Additionally, the electrolytic nature of these capacitors allows them to offer an extremely long life in comparison to other capacitor types - and this model offers up to an impressive 5000 hours of life. Furthermore, the capacitance range of the capacitors are also quite high - ranging from 2.2µF up to 33µF.In conclusion, LLG2D152MELA50 is an aluminum electrolytic capacitor with many desirable features which make them suitable for a variety of applications such as high frequency switching power supplies, voltage regulated power supplies, audio applications and automotive applications. They provide very low ESR and offer a long life, making them a reliable and cost effective choice for energy storage applications.
