IRV1600 Datasheet, PDF (1/2 Pages) RHOPOINT COMPONENTS – HIGH POWER, WIRE WOUND, METAL CLAD RESISTORS

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.
