Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in a variety of applications. The EKYB101ELL681ML40S is an example of such a capacitor, and its application field and working principle will be discussed in this article.

Application Field

The EKYB101ELL681ML40S aluminum electrolytic capacitors are used in the electronics industry for numerous applications. They are used to filter unwanted noise from transmissions and supplies, to store energy and protect circuits against overvoltage and transients, and as an energy source in power supplies. In audio applications, they are used to provide low-frequency filtering. They are also used in automotive and aircraft electronics, providing stable power sources in applications such as electronic control units, car alarms, and other vehicles.

Working Principle

The EKYB101ELL681ML40S aluminum electrolytic capacitor is a polarized, non-polarized capacitor with a high dielectric constant. The dielectric is a thin oxide film formed on the anodized aluminum foil on the positive and negative plates, usually producing high capacitance but limited voltage breakdown ratings. This foil is then rolled up into a cylindrical shape with the two endplates. The capacitance value is determined by charging and discharging charges on the two plates.

When current is applied to the electric circuit, a voltage drop occurs at the anode and charges the anode to become positive. The positive charge accumulates and forms a surface electric field on the anode. As a result, electrons on the anode flow to the cathode. This process creates an electric current from the anode to the cathode. As the amount of charge on the anode increases, the electric field increases, which further increases the electric current, and the cycle continues.

The stored energy in the capacitor is gradually released back to the circuit as the current flow is stopped. Thus, EKYB101ELL681ML40S aluminum electrolytic capacitors regulate the current in a circuit, providing power stability and preventing power surges. They also provide filtering for noise in transmissions and supplies.

Conclusion

The EKYB101ELL681ML40S aluminum electrolytic capacitors are used in a variety of electronic applications, and their working principle relies on the formation of a thin oxide film on the anode and forming an electric current between the anode and the cathode. This capacitor is ideal for filtering noise, protecting circuits against overvoltage and transients, storing energy, and providing a stable power source in various applications.
