Product Overview
The THF 104 is a stainless steel retaining spring designed for securing transistors to heatsinks. It is compatible with transistor case styles TO-220, TO-247, TO-248, and TO-3P, and is specifically suited for use with SK 104 profile heatsinks. The spring provides reliable mechanical pressure to ensure optimal thermal contact between the transistor and the heatsink surface. With a plate thickness compatibility of 1mm to 2mm, the THF 104 uses a clip-style mounting method, making it easy to install and remove without tools. Its compact dimensions—38.5 mm length, 7.8 mm height, and 4 mm depth—make it ideal for space-constrained designs. The product is RoHS compliant, manufactured in Germany, and widely used in thermal management applications across industrial and electronic systems.
