Part Data Audit and Review
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.
Thought for 15 sec
I’ll audit the inductor part data, find and attach the official datasheet if missing, then compare the symbol/footprint/pin metadata against the datasheet and summarize any mismatches.
Thought for 24 sec
Initial inspection shows this is a 2-pad inductor part project with footprint and 3D model assets present, but no BOM entry and no nets. I’m now locating the official datasheet and will update the part metadata if needed.
Worked for 8 mins 58 sec
Completed the SRN3012BTA-100M part audit and created Part Audit: SRN3012BTA-100M.
Key result: the official Bourns datasheet URL is already set, the 2-pad footprint matches the datasheet-recommended land pattern, and review now reports no violations. Only metadata issue flagged: both symbol terminals are currently
Unspecified; they should ideally be Passive with pin descriptions like “Inductor terminal 1/2.”Fix pin metadata
Verify footprint dimensions

Mechanical / Footprint Cross-check
Datasheet product dimensions:
- Body length: 3.0 +/-0.2 mm
- Body width: 3.0 +/-0.2 mm
- Height: 1.0 +/-0.2 mm
- Additional bottom/terminal-related dimensions shown by OCR: 2.7 +/-0.3 mm and 0.9 +/-0.3 mm
- Note: body dimensions do not include termination; add 0.1 mm for maximum overall dimensions with termination.
Project footprint:
- Two SMD rectangular pads
- Pad 1 center: x = -1.100 mm, y = 0
- Pad 2 center: x = +1.100 mm, y = 0
- Pad size: 1.300 mm x 3.500 mm each
- Pad center-to-center distance: 2.200 mm
- Pad inner gap: 0.900 mm
- Fab outline: 3.0 mm x 3.0 mm
- Courtyard: 5.5 mm x 5.5 mm
- 3D model present and associated
Footprint assessment:
- The footprint pad length of 3.5 mm and inner gap of 0.9 mm align with the datasheet OCR-extracted recommended layout dimensions.
- The 3.0 mm x 3.0 mm fab outline matches the datasheet nominal body size.
- The 5.5 mm x 5.5 mm courtyard is conservative and acceptable for assembly clearance.
Schematic Symbol / Pin Description Cross-check
Datasheet electrical schematic shows a simple two-terminal, non-polarized inductor. The two terminals are functionally interchangeable passive terminals.
Project symbol/terminal state:
- Two terminals are present with pin numbers 1 and 2.
- Terminal pin type is currently set to
Unspecifiedfor both terminals. - Terminal pin descriptions are not populated.
- No nets are defined; this is expected for a standalone part project.
Symbol assessment:
- Terminal count matches the datasheet: 2 terminals.
- Polarity is not relevant; the inductor is non-polarized.
- Mismatch / improvement: both terminals should be marked as passive inductor terminals rather than
Unspecified, and pin descriptions should be populated, e.g.Inductor terminal 1andInductor terminal 2.
Mismatches / Issues Flagged
- Terminal metadata incomplete: both schematic terminals have
Pin Type: Unspecified; recommended value isPassive. - Terminal descriptions missing: add pin descriptions for pins 1 and 2.
- The library/project part metadata has the datasheet URL available, so no datasheet URL update was required.
- No BOM entry appears in the project BOM view, likely because this is the part project itself rather than a design instance using the part.
Review Result
Initial automated review reported one documentation issue: the project had no documentation. This audit file addresses that missing documentation item.
