Presentation / Conference Contribution
Stubbs, D. M., Pulko, S. H., & Wilkinson, A. J. An investigation of the sensitivity of embedded passive component temperatures to PCB structure

The embedding of passive components such as resistors, capacitors and inductors within printed circuit boards (PCBs) is motivated, to a large extent, by the desire for increased miniaturization of electronic goods. However, resistors and, to a lesser... Read More about An investigation of the sensitivity of embedded passive component temperatures to PCB structure.
