ELECTRONICS: Vishay Intertechnology Inc. has enhanced its 101/102 PHR-ST screw-terminal power aluminum capacitors with larger 90 x 146-mm, 76 x 220-mm, and 90 x 220-mm case sizes, and 13-mm terminals.Featuring a cylindrical aluminum case insulated with a blue sleeve and pressure relief in their disc, the 101/102 PHR-ST devices are now available in 11 case sizes, ranging from 35 x 60 mm to 90 x 220 mm. The new large cases sizes allow for additional high capacitance/voltage combinations from 1F at 25V to 10,000 µF at 450V.
The 101/102 PHR-ST capacitors offer a high rated ripple current to 49.1 A at 85C, and a long useful life of 10,000 h to 15,000 h at 85C. The devices are now available with 8-mm terminals on the standard high-post M5 disc, or 13-mm terminals featuring the new high-current M6 disc. The capacitors are compliant to RoHS Directive 2002/95/EC.
As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the 101/102 PHR-ST devices are ideally suited for dc-link capacitors in high-power switched mode converters and energy storage in pulsed power applications. End products include rail traction for trains and subways, single- and three-phase motor controls, inverters for solar fuel cells, UPS devices, and medical and industrial equipment.
Samples and production quantities of the 101/102 PHR-ST capacitors are available now, with lead times of 12 weeks.
