Manufacturing, DFM & DFT — question 4 of 10
Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.
You're selecting a resistor for a current-sense circuit that will see up to 500mA continuously in an enclosure that can reach 70C ambient. The datasheet lists a 1/10W (0.1W) power rating at 25C with a derating curve that linearly drops to 0W at 125C ambient. If the resistor dissipates 60mW at your worst-case current, would you approve this part for the design as-is? Walk through your reasoning.
This one resolves to a number. Give the value in the field below and your reasoning in the box — the number is checked exactly, by arithmetic.
