Heat Sinks

CUI Device’s line of heat sinks is available in board level and BGA designs. Compatible with TO-218, TO-220, TO-252, and TO-263 transistor packages as well as ball grid array (BGA) package types, our aluminum heat sinks and copper heat sinks are conveniently measured under four conditions for thermal resistance, making it easier to select the optimal heat sink for your natural convection or forced air cooled system.
