Aluminum electrolytic capacitors are components that employ an aluminum oxide thin film as the dielectric material and electrolytic solution as the conductive medium, which is formed on the surface of the anode aluminum foil. The EKMQ451VSN121MP35S is an aluminum electrolytic capacitor that has a wide range of applications. This article will discuss the application field and working principle of the EKMQ451VSN121MP35S.

The EKMQ451VSN121MP35S aluminum electrolytic capacitor has a capacitance of 0.22μF. Its voltage rating is 4V, and its rated current is 55mA. Its size is 6.3mm x 11mm, and it has a pitch of 2.5mm. Due to its combination of small size, high capacitance, and low voltage rating, the EKMQ451VSN121MP35S is suitable for use in circuits where space is limited. It is widely used in numerous small electronic devices, such as remote controls, digital cameras, and smart phones.

The EKMQ451VSN121MP35S aluminum electrolytic capacitor is constructed of four parts: two aluminum foils (an anode foil and a cathode foil), an insulating paper separator, and an electrolytic solution. The anode foil, which is the positively charged electrode, is coated with an electrolytic solution containing aluminum ions. The cathode foil, which is the negatively charged electrode, is connected to the anode foil and is also coated with an electrolytic solution containing aluminum ions. The electrolytic solution acts as a dielectric, allowing for charge separation between the two foils. The insulation paper separator is placed between the two foils to maintain the electrical insulation between them.

When the EKMQ451VSN121MP35S aluminum electrolytic capacitor is in operation, a voltage is applied to the circuit. This voltage causes electrons to flow from the anode to the cathode. The electrons combine with the aluminum ions in the electrolytic solution, creating an oxide thin film on the surface of the anode foil. This thin film forms a barrier that prevents the electrons from flowing back. This creates a potential difference between the anode and the cathode, allowing the capacitor to store electrical energy in the form of an electric field.

In conclusion, the EKMQ451VSN121MP35S aluminum electrolytic capacitor is a type of capacitor that is used in a variety of electronic devices. Its small size, high capacitance, and low voltage rating make it ideal for space-constrained applications. It is constructed of two aluminum foils and an electrolytic solution, and it works by creating an oxide thin film on the anode surface that prevents the electrons from flowing back. This creates a potential difference between the anode and the cathode, allowing the capacitor to store electrical energy in the form of an electric field.
