Vishay – New three-phase cylindrical capacitors for power electronicsJul 7 2012 - Passives [More Passives Articles]
A new series of three-phase cylindrical capacitors, for power electronics applications, has been introduced by Vishay, featuring high current capabilities, nine standard voltage ratings from 400VAC to 1650VAC, and a wide range of capacitance values and packaging options.
The EMKP capacitors released today are available in four heights from 160mm to 265mm and five diameters from 64mm to 136mm. The devices offer high current ratings up to 3 x 56A and 3 x 104A (depending on the bushing type), impulse currents up to 21.3kA, very low self-inductance <100nH, low series resistance down to 0.6mohm, and capacitance values from 4µF to 600µF with a capacitance tolerance of ±5%.
Optimized for power factor correction, AC filtering, and harmonic filtering applications in three-phase mains, traction and industrial drives and converters, wind turbines, and solar inverters, the EMKP three-phase capacitors are metalized polypropylene film devices with self-healing characteristics.
EMKP 3-phase devices offer a high reliability rating of 120 FIT and a long lifetime expectancy of 100,000 hours at +70C at rated voltage. The capacitors are specified for an operating temperature of –40C to +85C and meet IEC 61071-1, IEC 61881, and IEC 60831 standards. Terminal-to-terminal test voltage is 1.5 times the rated AC voltage for 10 seconds, says the company.Electropages - Electronics Components News, From Leading Electronics Distributors.
