Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are typically cylindrical and use two metal plates, with a spacer material like paper or polyester, to separate them. It is created from alternating layers of metal foil, a non-conductive layer, and electrolyte solution. Due to the large surface area that the aluminum foil provides, it has a higher capacitance than a comparable ceramic capacitor or paper and liquid capacitors. It is also a cost-effective solution and can store more energy than other types of capacitors.

ELXM401VSN121MP35S Application Field and Working Principle

The ELXM401VSN121MP35S is best suited for use in power supplies, switching power supplies, and communicatio n equipment. It is also well suited for automotive, industrial, aerospace, and medical applications. Typically, the ELXM401VSN121MP35S is used for coupling, decoupling, energy storage, and filtering inductive circuits. Its wide capacitance range makes it highly versatile for a variety of applications.

The ELXM401VSN121MP35S utilizes an anodic aluminum oxide film as its dielectric, which is then rolled into the anode. The anode is then rolled onto a spacer material such as paper or polyester, and the two metal plates are connected by a wire. This metal layer is then filled with an electrolyte solution, creating the complete capacitor. The electrolyte solution provides a dielectric that is highly resistant to electrical breakdown, providing a high dielectric constant. The electrolyte separator also acts as a buffer, keeping the two metal plates from coming into direct contact and thus preventing shorting.

When a potential difference, or voltage, is applied to the aluminum electrolytic capacitor, the dielectric acts as an insulator, preventing electrical current from flowing in the circuit. However, when a current is applied to the capacitor, the metal plates allow electrons to flow and the dielectric absorbs the charge, allowing the capacitor to temporarily store electrical energy.

Conclusion

The ELXM401VSN121MP35S aluminum electrolytic capacitor is a versatile component, providing a high capacitance in a compact package. Its anodic aluminum oxide dielectric, combined with its electrolyte separator, provides excellent electrical properties, high-temperature stability, and a long life.
