Aluminum electrolytic capacitors are widely used in a variety of applications and can be found powering motors, lighting, tools and many other electrical components. The USA1V100MDD application field and working principle can be broken down into three parts: Electrode Construction, Capacitance, and Voltage Rating.

Electrode Construction

The USA1V100MDD application field and working principle use aluminum foil as an anode material, to provide maximum capacitance per volume of the capacitor. The anode is lined with a protective layer of oxide, or polymers, and the oxide layer is impregnated with an electrolyte, usually a solution of boric acid with a surfactant and other additives. The cathode is usually formed from a layer of activated carbon, usually impregnated with a surfactant and additives. Activated carbon has a high surface area and is able to attract and retain a layer of electrolyte to form what is known as a "dry electrolyte" capacitance.

Capacitance

The USA1V100MDD application field and working principle use both an internal electric field and a self-healing electric field, which greatly improves the power efficiency of the capacitor. The self-healing characteristic is due to the protective layer of electrolyte that is able to reform after a period of overloading or excessive heat. This means that the USA1V100MDD is capable of withstanding overloads of up to 200% of the rated voltage, making them suitable for a wide range of applications.

Voltage Rating

The USA1V100MDD has a voltage rating of 100VDC and is suitable for a wide range of applications, from audio and general electronics, to lighting and motor control systems. The 100VDC rating also means that it is suitable for applications where the maximum voltage is above 100 volts, but the current rating is below the rated maximum of 1 Amp. The USA1V100MDD also has a maximum surge voltage rating of 400 volts, which makes it suitable for applications where peak voltage can exceed the rated 100 volts.

Conclusion

The USA1V100MDD application field and working principle make it an ideal choice for a wide range of applications. It has an electrode construction which provides maximum capacitance, a self-healing characteristic due to the electrolyte, and a voltage rating of 100VDC and a surge voltage of 400 volts. The combination of these features make the USA1V100MDD an excellent choice for a range of applications, particularly in audio and general electronics, lighting, and motor control systems.
