Aluminum electrolytic capacitors are the most commonly used type of capacitor, which is used in many applications across a wide range of industries. The LGN2X820MELB35 aluminum electrolytic capacitor is a small, low-profile, surface mount, hermetically sealed capacitor with a capacitance range of 820 μF to 2200 μF and an operating temperature range of -55°C to +100°C.

Application Field

The LGN2X820MELB35 is generally used in applications where space is limited, but where a relatively large capacitance is needed. It is suitable for applications in electronic equipment such as switch-mode power supplies, DC-DC converters, inverters, UPS systems and auxiliary power supplies, and other applications where a low-profile, small-footprint capacitor has excellent power-handling capabilities. It is also used in battery-powered equipment such as portable radios and cellular phones, as well as in automotive radios and other automotive electronics.

Working Principle

An aluminum electrolytic capacitor works by storing electrical energy as electrostatic charges, held between two aluminium foil plates, separated by a paper dielectric material. These foils are etched in a way that many small capacitors are formed in series, increasing the total capacitance value. An electrolyte, which is an electrically conductive liquid, is applied on the dielectric layer filling all the tiny cavities between the foils. This electrolyte serves as a conductive layer that enables current flow. To support the electric fields created by the capacitance, a metal sleeve is used to provide mechanical strength and stability.

The dielectric used in the LGN2X820MELB35 aluminum electrolytic capacitor is a self-healing rubber-like material, allowing some flexibility for a wide range of operating temperatures. The anode and cathode endplates are made from aluminium, providing a low ESR (Equivalent Series Resistance) along with excellent heat dissipation capabilities.

Conclusion

The LGN2X820MELB35 aluminum electrolytic capacitor is a low-profile, surface mount capacitor, offering excellent power-handling capabilities for many applications across a wide range of industries. Its hermetically sealed construction and self-healing rubber-like dielectric material makes it suitable for a wide range of operating temperatures and conditions. For applications that require a relatively large capacitance in a limited space, the LGN2X820MELB35 is a perfect choice.
