Ohmite R3J150 Radial Tubular Wirewound Resistor
The Ohmite R3J150 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 are coated with silicone-ceramic). These resistors are ideal for applications requiring precise resistance and reliable performance in PCB designs. Values above 3.9K (3W) and 8.2K (5W) should be used with caution and may require burn-in or thermal cycling.
