ALS80H134LM040

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors or super capacitors, are a type of capacitor that uses an electrolyte, typically a solution of boric acid and ethylene glycol, as the dielectric medium. The dielectric medium allows for a larger capacitance per volume compared to ceramic or film capacitors, making aluminum electrolytic capacitors highly desirable among manufacturers. Additionally, they experience a wide range of operating temperatures and exhibit excellent electrical and environmental stability.

ALS80H134LM040 Application Field and Working Principle

The ALS80H134LM040 is a type of aluminum electrolytic capacitor that is used in a range of applications due to its high-capacity, low-ESR, and low-profile construction. It is specifically designed for use in car audio, telecommunication, computers, and other electronic applications that require a high ripple current capability. The ALS80H134LM040 features an electrolyte that has been chemically treated and pressurized, creating an edge that connects to the dielectric medium. This process exponentially increases the number of electrons that can pass between the two plates, resulting in an increased capacitance. Additionally, due to its low ESR, the ALS80H134LM040 is well suited for unstable current flows such as dimmers.

The ALS80H134LM040 has a stackable structure, allowing for a higher capacitance in a smaller package. It is comprised of an anode and a cathode, which are located on opposite sides of the capacitor. As current is passed through the capacitor, an electrochemical reaction occurs, causing an electrolyte solution to be formed between the two plates. This electrolyte solution forms a dielectric barrier, which is responsible for accumulating charges between the two plates and providing the capacitance of the capacitor.

In terms of operating temperatures, the ALS80H134LM040 is capable of performing in temperatures ranging from -40°C to +85°C, with an endurance temperature of 105°C for up to 1000 hours. The capacitor is rated for a voltage of up to 63 Volts with a maximum peak working voltage of 72 Volts. Furthermore, it has a maximum capacitance of 4,000uF with a capacitance tolerance of -20%/+80%.

When utilizing the ALS80H134LM040, it is important to consider the following guidelines. Firstly, when selecting the mounting type, it is best to use a perpendicular installation or a special clip for heat dissipation. Additionally, it is important to take into consideration an appropriate ripple current value and ensure proper decoupling to minimize ESR values. Lastly, it is important to ensure appropriate soldering techniques being applied, as excessive heat can damage the aluminum electrolytic capacitor.
