OPUTE Graphite Thermal Sheet 300–700 W/m·K Heat Spreader Film – Custom Die-Cut Sizes
OPUTE Graphite Thermal Sheet 300–700 W/m·K Heat Spreader Film – Custom Die-Cut Sizes
OPUTE Graphite Thermal Sheet
Ultra-Thin Graphite Heat Spreader | Custom Die-Cut Shapes
Graphite thermal sheets are engineered to spread concentrated heat across a larger surface area in space-constrained electronics. The graphite layer provides high in-plane thermal conductivity, while optional adhesive and protective film constructions support convenient assembly.
Key Features & Benefits
- Designed for lateral heat spreading in thin electronic assemblies
- Flexible integration into space-constrained product designs
- Available in multiple grades and constructions
- Custom die-cutting and size options for production assembly
Typical Applications
- Smartphones, tablets and ultra-thin laptops
- LED lighting and flat-panel displays
- IC, CPU and MOSFET heat spreading
- Telecommunications and compact electronics
