UCD1E330MCL1GS Capacitors

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized capacitors which are mainly used for storing energy and for filtering, decoupling and smoothening of electrical circuits. The UCD1E330MCL1GS is a particular Aluminum electrolytic capacitor from NCC. Aluminum electrolytic capacitors are characterized by a large capacitance per volume ratio and energy density, very low ESR and wide operating temperature range from -40 °C to 125 °C.

Application Field

UCD1E330MCL1GS Aluminum electrolytic capacitors mostly find their primary application in the field of power conversion and filtering. The UCD1E330MCL1GS also find good application in switch-mode power supplies, LED lighting, telecommunications, audio amplifiers and PCs. Apart from these primary applications, the UCD1E330MCL1GS can also be used as back-up capacitance in the memory of motherboard or sound card, or in any other very low power device that requires compact capacitance.

Working Principle

The UCD1E330MCL1GS is a high-voltage electrolytic capacitor whose construction takes the form of a cylindrical metal case with a plastic cover and with an anode inside the metal case and a cathode made of two parallel plates. When voltage is applied to the capacitor, the electrolyte inside the capacitor is activated, creating an electric field between the anode and the two parallel cathodes. This electric field creates an electric dipole across the capacitor, thus producing charge, the amount of which depends on the voltage difference and the specific capacitance.

The anode of the UCD1E330MCL1GS and the two parallel cathode plates are made of a highly conductive metal oxide which is usually aluminum oxide. This oxide has a dielectric constant higher than that of air and other dielectric materials, which results in the large capacitance or coulombic efficiency of the capacitor. As compared to other types of capacitors, the UCD1E330MCL1GS is usually used in a much smaller size and with much lower power consumption. This makes the UCD1E330MCL1GS ideal candidates in a wide range of applications, from power conversion to filtering.
