GREENVILLE, S.C., June 17, 2013 /PRNewswire/ — KEMET Corporation (NYSE: KEM), a leading manufacturer of tantalum, ceramic, aluminum, film, paper and electrolytic capacitors, today announced the release of the new ALS60/61 Screw TerminalA capacitor termination that uses a screw to connect the capacitor to the electrical circuit. The terminals may egress from any direction of the capacitor body. 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.
