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.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
