Aluminum electrolytic capacitors, also known as electrolytic capacitors, are capacitors that use aluminum foils with an oxidized surface as the anode electrode and a paper-like dielectric as the electrolyte. One of the most widely used types of aluminum electrolytic capacitors is the EEE-HA1C471UP, which is widely used for applications such as bypass, filtering, and surge protection.

The EEE-HA1C471UP aluminum electrolytic capacitor is a radial-lead type electrolytic capacitor, meaning that it uses a radial lead arrangement where it has two pins perpendicularly connected to the capacitor shell. The shell is usually made of aluminum and the pins are usually silver-plated. The electrolyte (paper-like film) is usually composed of aluminum oxide layers and is sandwiched between aluminum foil plates.

The EEE-HA1C471UP aluminum electrolytic capacitor has a capacitance of 470µF, a working voltage of 16V, and a temperature range of -40° to +105° C. It has an endurance of 2000 hours at +105°C, and a low ESR rating of 0.25Ω. It also has an insulation resistance of 100MΩ (500VDC), and a ripple current of 4.62mA. The electrolyte used is also a low-resistance type, providing high capacitance, low ESR and high insulation resistance.

The working principle of the EEE-HA1C471UP aluminum electrolytic capacitor is relatively simple. When the capacitor is connected to an input voltage, the voltage caused by the capacitor produces an electric field, which attracts ions from the external environment. These ions are adsorbed on both electrodes, and form an electric double layer. An electric charge is thus built up on both electrodes, and capacitance is created. The capacitance of an aluminum electrolytic capacitor is often much greater than that of other types, because the dielectric layer in these capacitors is relatively thin.

The EEE-HA1C471UP aluminum electrolytic capacitor is widely used in various applications, such as power supplies, switching regulators, LED lighting, smart grids, and home appliances. Its primary purpose is to filter out high-frequency sound and noise, thus improving the sound quality of the product. It can also be used to provide a steady voltage, protect circuits from current surge, or to act as an energy storage device for short-term effects.

In conclusion, the EEE-HA1C471UP aluminum electrolytic capacitor is a reliable and versatile component that has many advantages. Its high capacitance, low ESR rating, and high insulation resistance make it an ideal choice for a variety of applications, such as bypass and surge protection. Furthermore, its relatively simple working principle ensures that it will remain functional in a wide range of environments despite its age.
