IRV1600-2800 HIGH POWER, WIRE WOUND, METAL CLAD RESISTORS The IRV1600-2800 (V=vertical) models are our highest power, wire wound, metal clad resistors. These models have an extruded aluminium housing providing strong and rugged protection. Options include flying leads or tab terminals and inductive or non-inductive windings. The most common applications for these models are: motor drives, braking and snubber applications and power sources for industrial equipment. These models are fully RoHS compliant.
