Fujipoly America introduced thermal interface caps that are designed to transfer the heat generated by transistors to nearby heatsinks. The slide-on thermal interface caps are available in multiple lengths and material thicknesses and are molded to fit TO-220 and TO-3P transistors. The caps have a thermal conductivity ranging from 1.2 to 1.7W/mºK and a thermal resistance between 0.42 and 1.35º Cin²/W, depending on which Sarcon material is chosen.
