Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are energy storage components that utilize electrochemical principles to provide an electrical storage medium. They are made up of two aluminum plates, separated by an electrolyte. One plate is etched with a special coating called an anode dielectric, and this coating attracts charge. This charge is stored until it is needed. When a voltage is applied, the charge is released, and when it is removed, the capacitor will slowly discharge. They are commonly used in many applications, such as in power supplies, DC power supplies, automotive systems, and generators.

381EL151M450K042 Application Field and Working Principle

The 381EL151M450K042 is a type of aluminum electrolytic capacitor. It is ideal for applications requiring high ripple current, low ESR, and a long useful life. This capacitor has a working voltage range of 6.3 to 1000 VDC and an operating temperature range of -55 to +105°C. As for its dimensions, it has a diameter of 15mm, a height of 21mm, and a lead pitch of 4.5mm.

As an aluminum electrolytic capacitor, the 381EL151M450K042 has an anode composed of pure aluminum foil and a cathode composed of a mixture of aluminum foil and manganese dioxide. The anode and cathode are separated by an electrolyte, which contains organic solvents, acid, and other components. When a voltage is applied, the charge is stored in the electrolyte between the anode and the cathode. This charge is then released when a voltage is removed. The 381EL151M450K042 is also designed for low ESR (equivalent series resistance) and has a long lifespan, making it ideal for applications where frequent voltage fluctuations are expected.

The 381EL151M450K042 is most often used in power supplies, DC power supplies, automotive systems, and generator systems, where its combination of high ripple current, low ESR, and long useful lifespan are needed. It can also be used in industrial applications, such as high-power motors, adjustable speed drives, and process controllers.
