This pocket reference is intended as a valuable quick guide for often used board- and system-level design formulae. This collection of formulae is based on a combined 50 years of analog board- and system-level expertise. Much of the material herein was referred to over the years via a folder stuffed full of printouts. Those worn pages have been organized and the information is now available via this guide in a bound and hard-to-lose format!

Many thermal metrics exist for semiconductor and integrated circuit (IC) packages ranging from RθJA to ΨJT. Often, these thermal metrics are misapplied by those who try to use them to estimate junction temperatures in their systems. This document describes traditional and new thermal metrics and puts their application in perspective with respect to system-level junction temperature estimation
