Ohmite’s 90 Series resistors, like the 93J20RE, are manufactured using a unique process that molds vitreous enamel over the resistive element, ensuring consistent dimensions and a hard, lead-free coating. This construction enhances mechanical integrity and allows for heat-sinking. These resistors are suitable for a wide range of industrial applications where reliability and durability are paramount, including power supplies, motor controls, and lighting circuits. The all-welded construction and flame-resistant coating contribute to their long-term performance and safety.
