Heatsinks with lock-in transistor retaining springs

Simplified transistor fastening on heatsinks with a reduction in cost is achieved using the new series of extruded heatsinks and lock-in springs made by Fischer Elektronik. The special geometry of the groove in the heatsink allows easy transistor fastening by means of a specially shaped stainless steel spring which is simply snapped in. This type of fastening ensures a firm hold for almost all versions and sizes of transistor cases (TO220, TO218,TO247 etc.), diverse SIP multiwatt and MAX types without holes. The special geometry of the groove in the heatsink in combination with the retaining spring ensures optimum heat transfer between the component and the heatsink. Fischer Elektronik are constantly extending their range of standard heatsinks and adapting them to meet new technical requirements. Customer-specific designs are possible without any problem.
