Aluminum Electrolytic Capacitors: EKZN250ELL272MK35S Application Field and Working Principle

Aluminum electrolytic capacitors are an essential component in modern electronics and are used to store electrical energy and to filter out certain frequencies. The EKZN250ELL272MK35S is a type of aluminum electrolytic capacitor, and this article provides an overview of its application field and working principle.

Applications

Aluminum electrolytic capacitors are well-suited for many applications including filtering, power supply filtering, and audio crossover networks. The EKZN250ELL272MK35S is a film capacitor with a long service life and high capacitance value, making it a great option for power supply filtering and audio crossover networks. It’s also suitable for power supply decoupling and general filtering purposes due to its low dissipation factor and low ESR.

Working Principle

Like all aluminum electrolytic capacitors, the EKZN250ELL272MK35S is a polarized capacitor that uses a form of aluminum oxide as the dielectric medium. The two leads of the capacitor are connected to the aluminum plates, one of which is an anode and the other of which is a cathode. When a voltage across the two plates is applied, a conventional current flows through the electrolytic, known as the capacitor’s charging current. The electrolyte creates an electric field between the aluminum plates, allowing electrons to move freely in and out of the capacitor’s dielectric layer. This current flow causes electrochemical reactions between the ions in the electrolyte and the metal electrodes, allowing the ions to accumulate on the surfaces of the metal plates. This process charge and stores electrical energy within the capacitor.

Conclusion

The EKZN250ELL272MK35S is a popular aluminum electrolytic capacitor that can be used for many types of filtering and power supply related applications. Its long service life and high capacitance value make it a great choice for audio crossover networks, decoupling, and general filtering purposes. Its operating principle is based on the electrochemical reactions that occur between the ions in the electrolyte and the metal electrodes, which create an electrical field and store electrical energy.
