Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a capacitor that uses aluminum oxide as the dielectric and two aluminum foils as the plates. The porous dielectric (oxide) forms only when an anode (positive electrode) is deposited on a thin aluminum foil and an organic electrolyte is applied. The oxide layer is formed over the anode plate due to a combined anodizing and oxidizing effect.

B41041A4687M Application Field and Working Principle

The B41041A4687M aluminum electrolytic capacitor is specially designed for use in various high frequency switching power supplies. It features an operating temperature range from -55°C to 125°C and a very low ESR value of 0.065ohm, making it an ideal choice for high-power applications. It is also designed with a highly reliable construction, including a corrosion resistant aluminum case and a rugged plastic end cap.

The working principle behind the B41041A4687M aluminum electrolytic capacitor is simple. It consists of an anode foil, a dielectric (the oxide layer formed from the combined anodizing and oxidizing effect), and a cathode foil. When a voltage is applied, electrons from the anode and cathode foil move across the dielectric in opposite directions, generating an electrostatic field. This electrostatic field is what allows the capacitor to store energy.

The B41041A4687M has a large capacitance of 1680µF, making it suitable for applications that require a high capacitance rating. It also has a long service life thanks to its aluminum foil construction. All these features make the B41041A4687M an excellent choice for a wide variety of applications.

The B41041A4687M is particularly well suited for use in high frequency switching power supplies. This is due to its excellent ESR, long service life, and large capacitance rating. It is also suitable for other high-power applications where reliability is of the utmost importance.

Overall, the B41041A4687M aluminum electrolytic capacitor is a great choice for a variety of applications, especially those involving high-power and high-frequency. Its low ESR, long service life, and large capacitance make it a reliable and efficient choice.
