HS Marston Black Anodised Aluminium Heatsink, Undrilled, 5.7C/W

The HS Marston 02HN 00500 A 200 is a high-quality, extruded aluminium heatsink engineered for reliable passive cooling in a variety of electronic applications. Finished with a durable black anodised surface, it offers superior heat dissipation and enhanced corrosion resistance, ensuring long-term performance and protection.

Its undrilled design provides exceptional flexibility, allowing engineers and technicians to create custom mounting arrangements tailored to specific project requirements. This makes it an ideal thermal management solution for prototyping, custom assemblies, and retrofit applications where standard drilled patterns may not be suitable.

With a low thermal resistance of approximately 5.7 °C/W, this heatsink efficiently manages heat from low to medium power electronic devices through natural convection. Its compact dimensions of 63.5 mm × 50 mm × 15.6 mm allow it to be integrated into space-constrained designs without compromising on cooling performance.

Constructed from extruded aluminium, it is both lightweight and highly effective at transferring heat away from sensitive components. The black anodised finish not only improves thermal emissivity for better heat radiation but also provides a robust, scratch-resistant surface.

This versatile component is well-suited for mounting directly onto printed circuit boards (PCBs) or within equipment chassis, making it a go-to solution for stabilising temperatures in power semiconductors, voltage regulators, and other heat-generating devices.
