The Ohmite Heatsinks, WV Series, are for TO-220 and TO-247 Power Resistor or similarly packaged semiconductors. These self-aligning Ohmite WV series heatsinks feature solderable feet for through-hole placement, and an integrated clip which provides 1.32 (lbf) of force on the center of the resistor, enhancing thermal performance and reducing parts count and assembly time.
