LNU2H472MSEJ

Aluminum Electrolytic Capacitors

LNU2H472MSEJ aluminum electrolytic capacitors are common parts used in electronic devices. Aluminum electrolytic capacitors are polarized, meaning that one of their two terminals must be connected to a positive voltage in order for them to work.

The LNU2H472MSEJ is a special type of electrolytic capacitor which features a large capacitance value (470uF), and a relatively low working voltage of 6.3V. It is capable of operating in temperature ranges from -40°C to +85°C and is constructed with a cylindrical aluminum body, making it suitable for use in a variety of applications.

The application fields of LNU2H472MSEJ aluminum electrolytic capacitors include AC and DC power supply filtering and bypass, as well as audio and signal filtering. Due to its high capacitance value, it is the preferred choice for use in large power switching circuits, DC-DC converters, and pulse power supplies. Additionally, it is often used as a charge reservoir in high-current circuits, as well as a buffer for switching regulators.

The working principle of the LNU2H472MSEJ aluminum electrolytic capacitor is based on the principle of electrolytic energy storage. This involves creating a linear electric field across an oxide-coated anode in order to generate a charge storage. The oxide coating acts as an insulator and prevents the electrical current from focusing on the cathode, thus increasing the capacitance value.

When a voltage is applied to the aluminum electrolytic capacitor, an electric field is generated between the anode and the cathode, creating a charge separation. This charge separation causes electrons to accumulate on the anode and an electrostatic repulsive force which opposes the current. As the voltage increases, the electrons accumulate on the anode until equilibrium is reached and no additional current can flow. This is known as the capacitor’s charge capacity or capacitance.

When the voltage is removed from the capacitor, the electric field reverses and electrons move from the anode to the cathode, generating an electric current. As the electric field is removed, the capacitor is discharged and can no longer provide energy. This is known as the capacitor’s discharge capacity or differential capacity.

Overall, the LNU2H472MSEJ aluminum electrolytic capacitor plays an important role in many electronic applications and is highly reliable and efficient. Its large capacitance value and low working voltage make it especially useful in high-current circuits and power supplies, making it a popular choice in the industry.
