Part Datasheet 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 11 sec
I’ll audit this part project’s existing metadata, symbol terminals, footprint/pads, and datasheet status; if the datasheet URL is missing, I’ll find the official TDK datasheet, update the part property, then compare pins/mechanics/specs and report mismatches.
Thought for 22 sec
I found this is a 2-terminal part project with a KiCad footprint and STEP model already attached, but no BOM entry or visible part-level datasheet property in the schematic view. I’m checking TDK’s official source now.
Worked for 14 mins 25 sec
Audit complete. I set the official TDK datasheet URL, confirmed the 2-terminal passive symbol and SMD footprint match the datasheet land pattern/body outline, and created the full report here: Part Datasheet Audit.
Key issue flagged: one generated library description mentions 6.4 mm height, but the TDK datasheet specifies 5.4 mm max. The project review is now clean after adding the audit documentation.

Mismatches / issues flagged
- Library description height text appears inconsistent: one library description string includes
7.5 x 7.0 x 6.4mm, while the TDK datasheet specifies 5.4 mm max height. The project description itself already says 5.4 mm, and the official datasheet URL is now set. - Pin descriptions are minimal: terminals are correctly typed as passive and numbered 1/2, but there are no explicit human-readable pin descriptions such as
Inductor terminal 1andInductor terminal 2. This is not an electrical mismatch, just metadata that could be improved. - Documentation was missing before this audit: the design review reported the project had no documentation; this audit file addresses that documentation gap.
Conclusion
The schematic symbol and footprint are consistent with the TDK datasheet for terminal count, passive pin behavior, body outline, SMD pad type, pad numbering, and recommended land-pattern dimensions. The only substantive mismatch found is the generated library description text that states a 6.4 mm height; the datasheet value is 5.4 mm max.
