EGXE401ELL470MLN3S

Introduction: The EGXE401ELL470MLN3S is a type of aluminum electrolytic capacitor. These capacitors are formed of two aluminum foils separated by a spacer, placed into a cylinder and impregnated with a gel-like electrolyte. Charged by the application of an electric field, these capacitors are used in a variety of consumer, industrial, and military applications.

Application Fields: EGXE401ELL470MLN3S capacitors are most commonly utilized in applications requiring high dc voltage, low capacitance, long operating life, and large capacitance. Applications include computing equipment, power supplies, invertors, lighting, audio systems, and high-frequency switching. Due to their ability to withstand extreme temperatures, they are often used in products operating in remote environments, such as space or military applications.

Working Principle: The working principle behind the EGXE401ELL470MLN3S capacitors is based on the familiar electric double layer concept. In this system, an electric field is applied between the two aluminum foils which causes the formation of a thin layer of electrically charged ions on the surface of each foil. This creates a net capacitance, measured in Farads, between the two poles.

The standard electric double layer concept also explains the behavior of the aluminum foil. The electric field applied between the two foils causes an accumulation of electrons on one side, and a shortage of electrons on the other side. This charge imbalance creates a strong electrostatic force which results in the aluminum foil expanding and contracting, thus changing its capacitance value.

EGXE401ELL470MLN3S capacitors also utilize a special electrolyte to enhance the double layer effect. This electrolyte plays an important role in controlling the surface charge and in limiting the current flow. It also helps reduce the level of internal heating, which can be detrimental to the device’s performance.

Advantages: The primary advantage of the EGXE401ELL470MLN3S capacitors is their extremely small size, measuring only 4 mm q(squared). This allows them to be used in applications where space is limited, such as in very small circuit boards or restricted environments. Additionally, these capacitors offer extremely high capacitance values, making them suitable for applications requiring high capacitance. Finally, the devices possess a long life time and can operate reliably in temperatures as high as +125°C.

Conclusion: The EGXE401ELL470MLN3S is a type of aluminum electrolytic capacitor which utilizes the standard electric double layer principle and a unique electrolyte to create a high capacitance device. These capacitors are most commonly used in applications requiring high dc voltage, low capacitance, long life, and large capacitance. They are superior in terms of size, offering extremely small sizes, and offer a long operating life in extreme temperatures.
