Aluminum electrolytic capacitors are a type of electrochemical capacitor that use an electrolytic solution as an encoding medium. The capacitors are designed with two electrodes, often made of aluminum or tantalum, and they are enclosed in a sealed container that keeps the liquid electrolyte enclosed. The container contains a positive electrode, an electrolytic solution, a negative electrode and conducting plates that act as electrodes. A voltage when applied to the electrodes, causes a flow of current through the solution, forming a layer of dissolved salt on the plates. This layer of solution forms an insulating layer between the electrodes and the inside of the container.

380LX472M100A042 Application Field and Working Principle

The capacitor has a maximum operating voltage of 400 VDC, which is ideal for direct current applications. The 380LX472M100A042 features a robust electronics grade polypropylene film, and a low ESR. It also offers excellent capacitance, providing up to 1,000 microfarad (μF) with a limited tolerance of ±20%.

These types of aluminum electrolytic capacitors typically have a longer service life compared to other capacitor types, due to the durable build and protective covering. The sealing of the aluminum electrolyte also helps protect the inner components from moisture and other elements that could lead to premature failure. The working principle of the aluminum electrolytic capacitors is a simple one. When a voltage is applied to the capacitor, charges migrate between the plates in the form of electrochemical reactions. This causes the charges to build up on one plate, resulting in an electric field being established between the two plates.

It is also important to note that the capacitance of aluminum electrolytic capacitors is proportional to the area of their plates and the distance between them. The higher the capacitance, the greater the electrical field it can store and the longer its service life. This is why aluminum electrolytic capacitors are a preferred choice for applications that require a large amount of capacitance, such as in DC power transmission.

The 380LX472M100A042 aluminum electrolytic capacitor has a temperature range of -55 to +125ºC and can be used in a range of applications, including DC power transmission, general purpose high-voltage applications, audio filtering and microprocessors. The high ripple current and frequency characteristics of the capacitor make it an ideal choice for pulsed power supplies, switching power supplies and voltage converters.

Overall, aluminum electrolytic capacitors are great for those applications that need reliable capacitance performance, long-term reliability, and a wide temperature range. The 380LX472M100A042 capacitor offers all of these features, and is perfect for use in a range of different applications.
