metal clad resistors

The IRV(V=vertical) & IRH(H=horizontal) models are our standard wire wound, metal clad resistors. The ULVand ULH models are UL approved versions of the IRV and IRH. These models have an extruded aluminumhousing providing rugged and strong protection. Options include flying leads or tab terminals, inductiveor non-inductive windings. The most common applications for these models are motor drives, brakingand snubber applications and power sources for industrial equipment.GENERAL SPECIFICATIONSModel Wattage Rating OnHeat Sink Resistance Range [ohms] Notes:StandardTolerances+-2%(G)+-5%(J)+-10%(K) OptionalTolerances+-1.0%(F)+-0.5%(D)+-0.25%(C)+-0.1%(B)ExtendedResistances>150K dependingon model(please enquire) Inductive Inductive Tab Terminals Flying Leads Tab Terminals Flying Leads IRV/IRH 60 60W 0.1-400 0.1-180 ULV/ULH 60 0.1-375 0.1-400 0.1-180 IRV/IRH 80 80W 0.1-910 0.1-110 ULV/ULH 80 0.1-281 0.1-910 0.1-110 IRV/IRH 100 100W 0.1-1.1K 0.1-240 ULV/ULH 100 0.1-225 0.1-1.1K 0.1-225 0.1-240 IRV/IRH 120 120W 0.1-1.3K 0.1-300 ULV/ULH 120 0.1-187 0.1-1.3K 0.1-187 0.1-300 IRV/IRH 150 150W 0.1-1.6K 0.1-390 ULV/ULH 150 0.1-150 0.1-1.6K 0.1-150 0.1-390 IRV/IRH 200 200W 0.1-2.2K 0.1-1.1K ULV/ULH 200 0.1-450 0.1-2.2K 0.1-450 0.1-1K IRV/IRH 300 300W 0.1-2.7K 0.1-1.5K ULV/ULH 300 0.1-300 0.1-2.7K 0.1-300 0.1-1.5K IRV/IRH 400 400W 0.1-4.3K 0.1-2.2K ULV/ULH 400 0.1-225 0.1-4.3 0.1-225 0.1-2.2K IRV/IRH 500 500W 0.1-6.8K 0.1-3K ULV/ULH 500 0.1-180 0.1-6.8K 0.1-180 0.1-3K CHARACTERISTICS1/Temperature Range -55C to +200C 2/Insulation Resistance 20Mohms minimum 3/Dielectric Strength IRV/IRH AC1500V, 3500V, 4500V, 5400V;Max. leakage current: 2mA ULV/ULH See Note 4/Temp.
