BOYD TV40G Heat Sink, TO220/TO218, 9.9°C/W, Aluminium

The BOYD TV40G is a high-efficiency, narrow channel-style heat sink designed for superior thermal management in compact electronic assemblies. Crafted from thick aluminium with a durable black anodised finish, it effectively dissipates heat from power components.

Its innovative design features twisted fins, which increase air turbulence around the unit. This enhanced airflow significantly improves cooling performance compared to standard straight-fin designs, ensuring your sensitive TO-220 and TO-218 packaged devices operate within safe temperature limits for increased reliability and longevity.

Key Features & Benefits

• Optimised Cooling: The twisted fin construction maximises heat dissipation in limited spaces.
• Robust Construction: Made from thick aluminium material for excellent thermal conductivity and mechanical strength.
• Durable Finish: The black anodised surface provides corrosion resistance and improves heat radiation.
• Space-Saving Design: With compact dimensions, it is ideal for densely packed PCB layouts.
• Dual-Device Compatibility: The horizontal mounting orientation allows it to accommodate two TO-220 devices simultaneously, offering a cost-effective cooling solution.
