 Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has extended its 159 PUL-SI series of snap-in power aluminum capacitors to a high rated voltage of 500 V at +105 °C. Designed for solar PV inverters, industrial motor controls, and power supplies, the enhanced devices feature a long useful life, 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. to 2.80 A and +105 °C, and max. ESRLow Equivalent Series Resistance down to 150 milliohms at 100 Hz.

Featuring a cylindrical aluminum case with a pressure relief valve, insulated with a blue sleeve, the new Vishay BCcomponents snap-in capacitors released today are available in a variety of case sizes ranging from 22 x 25 mm to 35 x 60 mm. At 500 V, the devices feature a maximum operating temperature to +105 °C and useful life of over 3,000 hours.

As polarized 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.. with a non-solid electrolyte, the 159 PUL-SI series devices are ideally suited for smoothing, filtering, and energy storage in pulsed power applications. The capacitors are also available in a keyed polarityAn electrical condition determining the direction in which current tends to flow. The quality of having two opposite charges. snap-in version.

Samples and production quantities of the 159 PUL-SI series capacitors are available now, with lead times of 10 to 12 weeks.
