The OHMITE W Series heat sinks are designed for through-hole mounting of TO-220, TO-247, and TO-264 packages. The unique design incorporates a tin-plated, solderable, integral spring clip with an extruded aluminum heat sink body, providing an all-in-one mounting solution. Key features include reduced assembly costs by eliminating fasteners, maximum repeatability due to the spring clip's consistent clamping force, and resistance to shock and vibration. These heat sinks are RoHS compliant and suitable for various industrial applications requiring efficient heat dissipation.
