Our extruded aluminium housing provides rugged and strong protection. These models are available with flying leads or Tab terminals and can be ordered with inductive or non-inductive windings. To conform to UL safety requirements, ULV/ULH models differ from IRV/IRH models in that: The resistance range is smaller, the flying leads are UL approved and the dielectric strength depends on the ohmic value.
