Ohmite R3J120 Radial Tubular Wirewound Resistor
The Ohmite R3J120 is a tubular radial terminal wirewound resistor specifically engineered for printed circuit board (PCB) integration. 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 minimize board temperature. The resistor utilizes a ceramic core coated with vitreous enamel (except for values above 4.7K (3W) and 7.5K (5W), which use silicone-ceramic coatings). These resistors are ideal for applications requiring precision and stability in a compact form factor. They are RoHS compliant and available in various resistance values and wattage ratings.
