Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electronic component that uses an anode of aluminum foil covered with an insulated oxide layer as the electrode, along with a liquid or solid electrolyte as the dielectric. This is used to store energy and increase the amount of current that can be drawn from a circuit. It consists of a metal casing and two electrodes: a cathode, typically made of nickel, and an anode, typically made of aluminum foil.

EEE-1EA331UP application field and working principle

The EEE-1EA331UP is a radial lead electrolytic capacitor designed for use in a variety of electronic applications. It is rated at 33UF and 25V, with a temperature range of -40 to +105 degrees Celsius and an expected life of 1,500 hours at 105 degrees. The capacitor is physically very small in size and is suitable for tight spaces where other capacitor types might not fit.

The EEE-1EA331UP has the positive terminal on the end of the capacitor and the negative terminal on the bottom surface. The capacitor works by creating a space between the two electrodes. As voltage is applied, the electrochemical reaction causes an accumulation of electrons on one of the electrodes, while the other becomes positively charged. This disparity allows current to flow through the capacitor, with the electrons being stored by the oxide layer. When the voltage is removed, the electrons are released back onto the surface of the aluminum foil.

The EEE-1EA331UP is used in a wide range of applications, such as power supplies, medical equipment, computers, consumer electronics, and many other electrical and electronic devices. It is commonly used for decoupling applications to remove noise from the power supply, and is often combined with additional capacitors to create power rails or increase output current.

Conclusion

The EEE-1EA331UP is a small yet powerful aluminum electrolytic capacitor well suited to a wide range of applications. Its small size and durability make it ideal for use in tight spaces, and its ability to store a large amount of current make it suitable for use in decoupling applications.
