Aluminum electrolytic capacitors, abbreviated as Al-E-caps, are electronic components consisting of two aluminum foils separated by an electrolyte and are typically used in power supplies and filters for noise suppression. Built for larger capacitance values than other types of capacitors, the LGG2Z182MELC35 Al-E-cap is designed for higher operating temperature, up to 105oC. The following discusses the application field and working principle of the LGG2Z182MELC35 Al-E-cap.

As with other Al-E-caps, the LGG2Z182MELC35 is primarily used as a filtering device to suppress noise in power supplies. It is also suitable for use in reactive load equipments such as motors, lamps, and heaters. This Al-E-cap is designed to handle higher operating temperatures, so it’s frequently used in HVAC systems, high-power audio amplifiers, and medical equipment. Additionally, its high efficiency lends itself to use in automotive, aviation, and space-constrained applications.

The LGG2Z182MELC35 operates using a working principle known as the Wet Electrolytic Process. In it, pure aluminum foil is coated in a layer of oxide film, which acts as an insulator. This makes Aluminum Oxide the dielectric, which is then penetrated by an electrolyte and sandwiched between two aluminum foils. The electrolyte further activates the aluminum oxide, leading to increased capacitance in the Al-E-cap. A slight positive charge is applied to the positive foil, leaving the negative foil with a slight negative charge. This allows electrical current to pass through in both directions with minimized noise interference.

The LGG2Z182MELC35 Al-E-cap boasts a maximum operating temperature of 105oC, and a wide operating temperature range of -40 to +105oC. It offers 6,000 hours of load life at 105oC, a wide capacitance range of 0.47—2,200 µF, and an extreme reliability of up to 4CHL Test (Cyclic High Load Test). It’s also RoHS and Reach compliant, making it an ideal choice for a variety of applications.

In summary, the LGG2Z182MELC35 Aluminum Electrolytic Capacitor is designed for higher capcity and improved stability due to its superior construction and high temperature tolerance. It’s an ideal choice for applications ranging from noise and harmonic suppression in power supplies to active load devices, due to its wide operating temperature range, low impedance and current leakage, and its ultra-high reliability.
