Vishay Intertechnology, Inc. NYSE: VSH today announced its technology lineup for PCIM Power Conversion Intelligent Motion Europe 2014, taking place May 20-22 in Nuremberg, Germany.
In booth 9-212 at the Exhibition Centre Nuremberg, the company will be highlighting its latest industry-leading semiconductor, optoelectronics, and passive component technologies for a variety of applications.Passive components from Vishay on display at PCIM Europe 2014 will include a wide variety of the company’s latest capacitors, resistors, and inductors. Featured capacitors will include Vishay Draloric high-voltage up to 40 kVp ceramic RF power up to 4000 kvar devices; Vishay BCcomponents power 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. 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. material or insulating medium. These capacitors are generally used in filtering, bypassing and couplingSituation where two circuits are connected together where only the AC voltage is passed.. that feature long life and high-temperature performance and film interference suppression devices; Vishay ESTA power electronic capacitors for wind turbines, industrial and traction drives, and power factor correction applications; Vishay Vitramon multilayer ceramic chipThe main differences between ceramic dielectric
The 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.

Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive., and the dielectricThe insulating material between the plates of the capacitor.

In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields. loss.Ceramic capacitors tend to have low inductance because of their small size. capacitors MLCCs for safetyClass X capacitors are used in “across-the-line” applications where their failure would not lead to electric shock. Class X safety caps are used between the “live” wires carrying the incoming AC current. In this position, a capacitor failure should not cause any electrical shock hazards, rather, a capacitor failure “between-the-lines” would usually cause a fuse or circuit breaker to open.-certified applications; Vishay Cera-Mite high-voltage, screw-mounting ceramic disc capacitorsConsists of two metallic plates separated by a ceramic 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. whose area and spacing determines the 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.. These capacitors are low cost and suitable for used for general purpose circuits.; and Vishay Roederstein polypropylene film capacitors for DC-link applications.
