Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are an indispensable component in the vast landscape of electronics due to its ability to store electric charge. It is also known as an “electrochemical capacitor” or “wet capacitor” due to its formation in a chemical electrolyte medium. It works by taking advantage of the sealing effect of a liquid electrolyte solution and its ability to conduct electrical current. The electric charge is then stored in a dielectric film that is placed on the two metal plates, either formed from aluminum foil or from a combination of nickel-plated steel and aluminum.

The UFG1K470MPM is an example of an aluminum electrolytic capacitor. This capacitor is part of the UFG series, which are designed for automotive applications. It is highly capable of providing a high capacitance value and high ripple current for power electronics applications. This capacitor has a compact form factor and offers an extended temperature range, with ratings up to 125°C. It features a low equivalent series resistance and possesses an impressive short life of 2000 hours.

The UFG1K470MPM works on the principle of electrochemical capacitors. The two metal plates of this capacitor consists of an aluminum layer and a nickel-plated steel layer, which are connected to the cathode and anode of a chemical electrolyte. Between the two plates is a special dielectric material, which is optimized in order to achieve the desired capacitance value. The chemical electrolyte inside the capacitor is an electrolytic gel and it provides two functions: firstly, to help seal the two metal layers together and secondly, to increase the conduction of the electric charge between the two plates. When an electric current is applied to the UFG1K470MPM a charge starts to accumulate between the two metal layers, which acts like a virtual capacitor.

The UFG1K470MPM is suited for a wide variety of applications. It is primarily used to filter DC power, particularly in power supplies such as power amplifiers, modules, DC/DC converters, and automotive electric systems. It is also used to filter or stabilize signals and eliminate interference, making this capacitor ideal for applications such as switching power supplies, TVs and TVs, and other audio equipment. Furthermore, the UFG1K470MPM is suitable for motor control applications due to its low ESR and high ripple current.

In conclusion, the UFG1K470MPM is an indispensable aluminum electrolytic capacitor that is suited for various automotive and power electronics applications. It is capable of providing a high capacitance value and is able to support a high ripple current. It is an ideal choice for applications such as motor control, power amplifiers, and other AC/DC converters. With its extended temperature range, low ESR, and impressive short life of 2000 hours, the UFG1K470MPM is a reliable and efficient choice for any electronics project.
