Ohmite 91J18R Vitreous Enamel Molded Resistor

Ohmite's 91J18R resistor is a high-quality wirewound resistor manufactured using a unique process that molds vitreous enamel over the resistive element. This construction ensures consistent dimensions and permits mounting in clips for heat-sinking benefits. The durable, lead-free vitreous enamel coating maintains a hard coating while operating at high temperatures, and the all-welded construction enhances mechanical integrity. Suitable for a wide range of industrial applications requiring robust and reliable resistance.
