Specific Heat of Electronic Components

Hi fredyMlg,

I'm going to give you links to the datasheets.

However, I doubt that they will have specific heat data. For that, you will have to contact the respective manufacturers. Contact info on the datasheets.

Or failing that, that materials are produced and a percentage are?

I'm not understanding what you mean here. Please elaborate.

thank you for your answer Mikerho.

what I meant in that question is what material used to manufacture a component , ie silicon, lead, etc and what percentage are?

That is information that will have to come from the manufacturer. If you can find out the materials in the package, you could possibly be able to estimate the average heat capacity from the package's general construction.

However, I believe that the fastest and easiest way to get this information is from the manufacturer. They undoubtedly have lots of thermal data developed while the product was in testing. If there's a chance you will be buying chips from them, they will help.
