Compact PDF of 53.9 KB bearing the part code 30CLJQ045 and filed among schematics, although the name points to a single component rather than a board. No brand, model or revision is stated. Expect electrical characteristics, maximum ratings and mechanical package data, which help when a power-path device is suspected of failure.
