Ohmite R3J10R Radial Wirewound Resistor
The OHMITE R3J10R 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 a silicone-ceramic coating. It's ideal for applications requiring precise resistance and reliable performance, and is RoHS compliant, making it suitable for environmentally conscious designs. Values above 3.9K (3W) and 8.2K (5W) are supplied with silicone-ceramic coatings.
