Wurth Elektronik Thermal Interface Sheet, 37 μm Thick, 1800 W/mK, 297 mm, 210mm, Acrylic and Graphite

This thermal Interface sheet is a thin heat-spreading medium designed to enhance thermal transfer between electronic components and cooling surfaces. It combines an acrylic Matrix with graphite to provide efficient lateral conduction while remaining compliant for close surface contact. The sheet functions across a wide temperature span and is suitable where a compact, low-profile thermal solution is required.

• 1800W/mK thermal conductivity improves heat-dissipation efficiency
• 0.037mm thickness enables minimal gap filling and low-profile integration
• Acrylic and graphite composition delivers Planar heat-spreading performance
• -40 to 120°C operating range supports varied thermal environments
• RoHS approval ensures restricted-substance compliance for assemblies

• Suitable for Compact power-electronics cooling assemblies
• Ideal for heat spreaders in high-density circuit stacks
• Used with modules requiring ultra-thin thermal coupling
• Can be used for thermal management in consumer electronics

The sheet uses an acrylic binder combined with graphite to provide a compliant Matrix that facilitates lateral heat movement while maintaining surface conformability.

The -40 to 120°C range allows use in both low-temperature start-up conditions and elevated operating environments without material degradation.

The product is supplied as a flat sheet sized 297 x 210mm suitable for cutting or trimming to required footprints.

It carries RoHS approval, confirming it meets the restricted-substances criteria for electronic assemblies.
