Vishay Releases New Series of 3-Phase Cylindrical Capacitors for Power Electronics
Vishay Intertechnology, Inc. introduced a new series of 3-phase cylindrical capacitors for power electronics featuring high current capabilities, nine standard voltage ratings from 400 to 1650Vac, and a wide range of capacitance values and packaging options.
The EMKP capacitors released today are available in four heights from 160 to 265mm and five diameters from 64 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 < 100 nH, low series resistance down to 0.6mΩ, and capacitance values from 4.0 to 600µF with a capacitance tolerance of ± 5%.
Optimized for power factor correction, ac filtering, and harmonic filtering applications in 3-phase mains, traction and industrial drives and converters, wind turbines, and solar inverters, the EMKP 3-phase capacitors are metalized polypropylene film devices with self-healing technology.
EMKP 3-phase devices offer a high reliability rating of 120 FIT and a long lifetime expectancy of 100,000 hours at + 70°C at rated voltage. The capacitors are specified for an operating temperature of -40 to + 85°C 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.
Samples and production quantities of the new EMKP 3-phase series capacitors are available now, with lead times of 8 to 10 weeks.
