Part Metadata Audit and Update

Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

I’ll audit the part metadata, find/update the official datasheet if needed, then compare the symbol/footprint/pins against the datasheet and summarize any mismatches.

flux

Audit complete. I updated the part metadata with TDK’s official datasheet URL and refreshed the description/properties from the datasheet.
Key result: the 2-pin symbol and copper land pattern match the TDK SPM4030T-1R0M datasheet; the main issues flagged are unspecified terminal pin descriptions and a minor fab-outline mismatch versus the 4.2 mm datasheet width. Full details are in Part Audit — TDK SPM4030T-1R0M. Review now reports no unresolved violations.
