RS PRO Universal Rectangular Aluminium Heatsink 100 mm x 120 mm x 37 mm 271-864

RS PRO 271-864 Universal Rectangular Aluminium Heatsink is engineered for efficient passive cooling in demanding electronic and power applications. This industrial-grade heatsink is constructed from high-performance anodised aluminium, ensuring optimal heat dissipation and enhancing the reliability and longevity of electronics subject to continuous operation and high thermal loads.

The universal rectangular form factor, with dimensions of 100 mm length, 120 mm width, and 37 mm height, provides ample surface area for rapid heat discharge. Its black anodised finish not only boosts thermal performance but also gives the heatsink a robust and professional appearance, making it ideal for installation in visible control panels, audio equipment, and laboratory hardware.

The design supports universal compatibility for retrofitting or original assembly in power supplies, industrial electronics, audio amplifiers, gaming PCs, and other thermal management-critical systems. The aluminium alloy structure is lightweight yet mechanically durable, allowing for straightforward installation without adding excessive weight or bulk to equipment assemblies.

The RS PRO 271-864 can be integrated within free-air or forced-air cooling setups. Its vertical fin arrangement is optimised for natural convection, while the extruded construction ensures manufacturing consistency and surface contact for effective heat transfer from devices such as power transistors, voltage regulators, MOSFETs, and high-power ICs.

Typical industrial use cases include electronic project boxes, instrumentation panels, power conversion units, automotive controllers, and laboratory test rigs. This heatsink is a practical choice for engineers seeking cost-effective, reliable cooling solutions for commercial or prototype projects.
