High thermal stability meaning
WebGlossary. Thermal Stability. A material is thermally stable if it does not decompose under the influence of temperature. One way to determine the thermal stability of a substance is to use a TGA (thermogravimetric analyzer).. The ASTM E2550 standard describes the thermal stability of a material as the “temperature at which the material starts to decompose or … WebTo better understand how thermal resistance is used, lets look at the following example: Power dissipated: 2W. RθJC = 4°C/W. RθCH = 0.25°C/W. RθHA = 6°C/W. TA = 25°C. Starting with the thermal equivalent of Ohm's Law: We want to solve for our junction temperature rise , so T becomes T J. Our power dissipated, P, is 2W.
