Heat Sinks

Circuit Specialists carries a variety of inexpensive, high-quality heat sinks — for ICs and TO-3, and TO-5 case types — for keeping your devices cool and efficient. We also have heat sink compounds, clip-on heat sinks, and Peltier modules. These Peltier modules, which are solid-state active heat pumps, are optimized for 12VDC and their edges are sealed with silicone to prevent dust and contaminants from getting into the unit, contributing a longer lifespan and greater efficiency.


We work hard to provide you with the best possible shopping experience. But don't take our word for it — here are some past customer reviews:
