Aluminum Electrolytic Capacitors

An Aluminum Electrolytic Capacitor (AEC) is an electrical component with two electrodes that are separated by an electrolyte. It is a polarized capacitor, meaning the voltage of one of the terminals must always be higher than the other, or it won’t function correctly. Compared to other types of capacitors, AECs are able to store more charge for a given amount of space.

B41456B4680M000 Application Field and Working Principle

The B41456B4680M000 is a radial leaded aluminum electrolytic capacitor. It is a high voltage, low ESR (Equivalent Series Resistance) capacitor that can operate over a temperature range from -55°C to 105°C. It has a rated voltage of 450V and can withstand ripple currents of up to 4.5 Amp.

This capacitor is widely used in power supplies, audio amplifiers, and other equipment where high ripple and current is required. It can also be used for filtering of AC power. The working principle of this capacitor is based on the Faraday’s law of electrolysis, which states that electricity passing through an electrolyte solution will cause a certain amount of ions to be separated from the electrolyte.

The two electrodes of the capacitor act as electrodes that attract and store ions, while the electrolyte provides a conducting medium between them. When AC power is applied across the two electrodes, ions get moved from one electrode to the other, thus creating an electrical field between the two electrodes. This field acts as a barrier, or capacitance, that allows for the storage of electrical energy.

In the B41456B4680M000 capacitor, the electrolyte is a non-aqueous electrolyte solution based on ethylene glycol and carbon dioxide. This combination of electrolyte provides a higher capacitance for a given size of device. The capacitor is further protected by epoxy side seals, which not only prevent leakage but also increase the surge strength of the capacitor.

The B41456B4680M000 capacitor is a highly reliable and widely used capacitor for power supplies, audio applications, and many other electronics. Its high voltage and low ESR make it a good choice for applications where high ripple current and filtering of AC power are required.
