Vishay Intertechnology Inc. (Malvern, PA) announced a new series of heavy-duty, metallized-film, power capacitors with current ratings as high as 150A and very low self-inductance. The new Vishay ESTA HDMKP Series devices serve as low-cost capacitor solutions for dc and ac filtering and for dc linking in uninterruptible power supplies and in power converters for traction and industrial drives.
Inductance for the new capacitor series is less than 50nH, and the devices' dissipation factor is less than 8 x 10-4 at a frequency of 1 kHz. The HDMKP capacitors are available in six standard voltages from 900Vdc to 2,700Vdc and from 220Vac to 660Vac, with voltages up to 4,800Vdc available on request. Capacitance values range from 40µF to 1,100µF, with a capacitance tolerance of ±5%. Capacitor height options range from 105mm to 260mm, with a standard diameter of 84.4mm.
Heavy-duty resistance to shock and vibration, as well as a reliability rating of 300FIT, contribute to the devices' lifetime expectancy of 100,000 hours at +60°C at rated voltages. Devices in the HDMKP Series are specified for an operating temperature of -40°C to +70°C at full rated voltage, or up to +100°C at half of the rated voltage, and meet IEC 61071-1, EN 61071, IEC 68-2 and IEC 61881 standards. Terminal-to-terminal test voltage is 1.5 times the rated dc voltage for 10 seconds.
Samples and production quantities of the new HDMKP Series capacitors are available now, with lead times of eight weeks. Pricing for US delivery in 50,000-piece quantities starts at $5.00 per piece.
