VXA-35-101E Ohmite

VX Series Heat Sinks For TGHE Series and SOT-227 Devices Ohmite introduces the VX series heat sinks for the Ohmite TGHE series and SOT-227 devices. This powerful heat sink has a unique profile that allows thru-hole soldering onto PCBs, panel mounting, or chassis mounting with fasteners. The VX series is an ideal heat sink that is designed for large power yet provides a light weight package and works with forced convection cooling.
