Selection Guide

Correct Thermal Interface Material Selection Guide

Selection of the correct Thermal Interface Material (TIM) is critical to the performance for each device. Proper selection is based on various material properties; Thermal Resistance, Voltage Isolation, Service Temperature and Wetting Properties. While selecting the right material involves considering the chemical and physical properties of the material, it also means choosing a product that will ensure the longest possible life expectancy in the working environment. Using the best material for the job can decrease your overall cost because otherwise similar products may have different price/performance ratios.
