Vishay has enhanced its 101/102 PHR-ST screw-terminal power aluminium capacitors with larger 90 mm by 146 mm, 76 mm by 220 mm, and 90 mm by 220 mm case sizes, and 13 mm terminals.
Featuring a cylindrical aluminium 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 mm by 60 mm to 90 mm by 220 mm. The new large cases sizes allow for additional high capacitance/voltage combinations from 1 F at 25 V to 10 000 μF at 450 V.
The 101/102 PHR-ST capacitors offer a high rated ripple current to 49,1 A at +85°C, and a long useful life of 10 000 to 15 000 hours at +85°C. 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 polarised aluminium electrolytic capacitors with a non-solid electrolyte, the devices are well 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.
