PCB heat sinks Fischer Elektronik

Fischer Elektronik and SCHURTER Electronics S.p.A. offer the ideal solution for heat dissipation of electronic components on the PCB.
Printed circuit board heat sinks from Fischer Elektronik offer excellent solutions for heat dissipation of components from both a thermal and assembly perspective.

The broad product portfolio of Fischer Elektronik is once again being expanded to include additional functional geometries of PCB heat sinks with snap-on transistor retaining springs.

The new PCB heat sinks of the SK 697, SK 701, SK 702, SK 703, SK 704 and SK 705 series offer efficient solutions for dissipation and are available in various sizes and lengths.
The heat sinks are fixed to the PCB via a threaded channel integrated into the heat sink base.
The individual heat sink can be screwed or fixed to the PCB using an M3 screw. It is also possible to press a captive solder pin (part number ELS 3) into the threaded channel instead of a screw. The solder pin is made of brass and has a solderable surface coating, which means that the heatsink is firmly connected to the PCB, for example during the reflow soldering process. The different transistor types, for example TO 220, TO 218, TO 247, various SIP-Multiwatt types and MAX without hole, are fixed using a groove geometry integrated into the profile and specially developed snap-on transistor retaining springs (part number THFU 1-7).

The specially shaped snap-on transistor retaining springs made of stainless steel are hooked directly into the groove, do not fall out and fix the transistors with high contact pressure on the mounting surface of the heatsink. The resulting simple installation, with a secure hold, ensures optimum heat transfer between the device and the heatsink surface.

The new PCB heat sinks are available with a black anodized surface as standard, although other surfaces and additional mechanical processes can be implemented and offered according to specific customer requirements.
