CHARLOTTE, N.C., March 16, 2015 /PRNewswire/ — KEMET Corporation (NYSE: KEM), a leading global supplier of electronic components, announced its new high voltage ALC10 Series snap-in aluminum electrolyticA polarized capacitor exhibiting a very high capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive./volume ratio that consists of two electrodes immersed in an electrolyte, with a chemical film that acts as a dielectricThe insulating material between the plates of the capacitor. The material is chosen for its ability to permit electrostatic attraction and repulsion to take place across it. The material will have the property that energy required to establish an electric field is recoverable in whole or in part, as electric energy. In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields. on one or both electrodes. Electrolytic capacitors are made by winding either plain or etched foils on which an oxide has been formed on the surface of one (either anodeAn electrodeA solid electric conductor through which an electric current enters or leaves in a medium through which current enters any nonmetallic conductor. or cathodeThe negative electrodeA solid electric conductor through which an electric current enters or leaves in a medium of a capacitor.) film. The etching of the foil increases the surface area and a considerable increase in capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. can thus be obtained. capacitorsConsists of two conducting electrodes, with the anodeAn electrodeA solid electric conductor through which an electric current enters or leaves in a medium through which current enters any nonmetallic conductor. having an aluminum metal oxide film acting as the dielectricThe insulating material between the plates of the capacitor.

These capacitors are generally used in filtering, bypassing and couplingSituation where two circuits are connected together where only the AC voltage is passed.. today at APEC 2015 in Charlotte, N.C.
These compact 550 VDC rated capacitors are designed for high ripple currentThis applies to a DC application with a superimposed AC voltage. The ripple current rating is the maximum AC current the capacitor can handle. applications and feature surgeA transient variation in the current and/or potential at a point in the circuit. voltage capability and very long life performance.
Developed at the KEMET Electrolytic Innovation Center in Weymouth, U.K., ALC10 Series capacitors are ideally suited for industrial and commercial applications demanding high reliability with operational life up to 18,000 hours. Typical ALC10 Series applications include frequencyThe number of complete cycles or vibrations per unit of time. Rate of alternation in an AC current. Expressed in cycles per second or hertz (Hz). converters, uninterruptible power supply (UPS) systems and high voltage switch mode power supplies (SMPS).
“As the voltage rails used in modern inverter-based systems continue to increase, the need for high voltage, high capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. solutions in smaller packages is critical,” said Mark Wright, KEMET Director of Technology, Electrolytic Business Unit. “The new electrolyte developed for the ALC10 Series allows for high voltage capabilities up to 550 VDC in a small, board mountable form factor, making them ideal for solar photovoltaic inverter and motor driver designs.”
