Temperature-Dependent Conductivity: Why k(T) Ruins “Catalog-Only” Designs

When Material Datasheets Can Lead Engineers Astray A material datasheet says thermal conductivity is 200 W/m·K. The calculations look accurate. The thermal simulation passes. The design moves forward. But after installation, temperatures rise higher than expected. What went wrong? The answer often lies in a factor many engineers overlook: temperature dependent conductivity, commonly written as […]
