Hello, I am working on a thermal model in Icepak. What is Theta JC (θjc) for ADF41510? Data sheet only provides JC and JA. Thanks, Mike
I appreciate the confirmation of Theta_JC. I would have expected Theta_JC as you described (bottom of part) to be an order of magnitude less than Theta_JA. Thanks, Mike
I don't disagree with you. They do seem closer than I would have expected. I wouldn't have guessed at an order of magnitude but I'd be guessing that junction to air would be two to three times higher. I looked at some other parts and see that they have similar junction to case thermal resistance and they seem to match on junction to case. So that is the number I would trust more. - Eamon
