THFU7

The THFU 7 is a retaining spring manufactured by Fischer Elektronik, specifically designed for securing low-profile transistors—particularly those in eSIP housings—to heatsinks. It is made from stainless steel and provides a spring force of approximately 40 newtons, ensuring firm and reliable contact between the transistor and the heatsink surface. This helps maintain optimal thermal conductivity and mechanical stability in electronic assemblies. The THFU 7 is compatible with a wide range of Fischer Elektronik heatsinks, including models like SK 480, SK 490, SK 574, SK 638, and LAM series variants such as LAM 3 K and LAM 6 D K. Its snap-in mounting style allows for quick and secure installation without the need for additional tools or fasteners.
