Ohmite 30J4R7 High Energy Wirewound Resistor

Ohmite Manufacturing’s High Energy Wirewound Resistors utilize unique winding techniques to maximize the effective joule rating of each resistor. Unlike standard wirewound resistors, these are wound to maintain a tight pitch, maximizing the resistive element's mass and ensuring consistent performance. This results in a fixed joule rating and fusing current for each part number. Available in axial, SMD, and heat sinkable packages, these resistors are suitable for a wide range of industrial applications requiring high power handling and reliability. RoHS compliant versions are available to meet environmental standards.
