The OHMITE R5J40RE is a tubular radial terminal wirewound resistor specifically engineered for printed circuit board (PCB) applications. Its radial construction allows for direct insertion into standard 0.10 inch matrix boards with 0.046 inch diameter holes, providing a built-in standoff to reduce board temperature. The resistor utilizes a ceramic core and, depending on the value, is coated with either vitreous enamel or silicone-ceramic coatings. These resistors are suitable for a variety of industrial applications where precise resistance and thermal stability are required. Values above 3.9K (3W) and 8.2K (5W) are supplied with silicone-ceramic coatings. Always check product availability at Ohmite's website.
