LNT2W332MSEG

Aluminum Electrolytic Capacitors

LNT2W332MSEG is a type of aluminum electrolytic capacitors which are compact in size and large in capacity. This type of aluminum electrolytic capacitor takes up minimal space while providing the maximum amount of energy storage while the enhanced electrical conductivity provides superior ripple current performance resulting in higher efficiency, lower losses, better system stability and greater overall performance.

Application Field

LNT2W332MSEG type aluminum electrolytic capacitors are widely used in many commercial and industrial applications such as for motor drives in industrial automation and electric vehicles, for power supplies in LED lighting and other energy harvesting systems, for power factor correction on power supply lines and for the high frequency filtering and EMC requirements of automotive electronics. For these applications, LNT2W332MSEG type aluminum electrolytic capacitors are typically chosen because of its combination of stability, low ESR, low leakage current and long life.

Working Principle

The working principle of the LNT2W332MSEG type aluminum electrolytic capacitors is based on the mechanism of electrolyte-filled capacitors in which aluminum is oxidized to form a thin layer of Al2O3 (alumina) on the surface of the aluminum foil. This reaction produces an electrically conductive film that provides an efficient dielectric and can support a large capacitance. The construction of the capacitor also uses a non-conductive paper separator that prevents the direct contact between electrodes and a conductive sealant to ensure back-leakage current is kept to a minimum.

The key design feature of aluminum electrolytic capacitors is the dielectric property of the electrolytic film. The electrolyte used in this type of capacitor is typically a solution of sulfuric acid and can provide a dielectric strength of up to 10,000 volts/mm. This capacitance property, combined with the low ESR and long life, makes aluminum electrolytic capacitors the ideal choice for many commercial and industrial applications.
