Part Audit 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 5 sec
I’ll audit the part metadata, locate the official datasheet if needed, update the Datasheet property, then verify the symbol, footprint, and pin descriptions against it.

Audit complete. The existing datasheet URL was already populated, so no update was needed. The symbol polarity, pin mapping, 5.0 mm lead pitch, and Ø10 mm footprint match the datasheet; metadata gaps and a potentially mismatched 3D-model identity/height are flagged in the Part Audit Report.

Symbol and terminal review
Table
| Pin | Symbol name | Footprint pad | Assessment |
|---|---|---|---|
| 1 | + | Rectangular pad 1 at x=0 | Correct polarity convention for a polarized capacitor |
| 2 | - | Circular pad 2 at x=5 mm | Correct polarity convention for a polarized capacitor |
The symbol has two passive terminals and clearly shows polarity. Pin numbering and footprint mapping are internally consistent. However, the terminals do not have explicit human-readable Pin Description properties; descriptions such as
Positive terminal and Negative terminal would improve metadata quality.Footprint review
- Footprint asset:
CAPPRD500W65D1010H1900.kicad_mod - Two plated through-hole pads on 5.0 mm pitch — matches the datasheet.
- Circular body outline is approximately Ø10.1 mm — matches the datasheet Ø10 mm nominal body.
- Drill diameter is 0.85 mm for a 0.6 mm lead — provides 0.25 mm diametral clearance and is reasonable.
- Pad 1 is rectangular and pad 2 circular, preserving positive-terminal identification.
- The source footprint/model naming references
H1900andRPF1018471M050K.stp, while the datasheet body length is 18 mm and the project MPN is JBLH2471M050E180RLM. The copper geometry is correct, but the 3D model identity and exact height should be visually or dimensionally verified.
Mismatches and metadata gaps
- Part Type is too generic:
Capacitorsshould ideally identify this as a polarized/aluminum electrolytic capacitor. - Description is incomplete: it contains sourcing identifiers and basic value/voltage, but omits radial THT construction, Ø10 × 18 mm case, ±20% tolerance, 105 °C rating, low ESR, and ripple-current capability.
- Electrical properties are not structured: capacitance, voltage rating, tolerance, temperature range, ESR, ripple current, and life are not present as dedicated project properties.
- Pin descriptions are missing: polarity names are present, but descriptive terminal metadata is absent.
- Manufacturer naming is ambiguous: the property says
DMBJ, while the datasheet identifies Dongguan Zhenbaojia Electronics and labels the part-number columnRuilong. Confirm whether DMBJ is the intended manufacturer/brand normalization. - 3D model/package naming mismatch risk: footprint/model filenames suggest a related 10×18/19 mm capacitor from another naming family. Footprint land geometry matches the datasheet, but exact model height and body identity are not proven by the filename.
Overall result
The electrical polarity, two-pin symbol, pin-to-pad mapping, 5.0 mm lead pitch, and Ø10 mm body footprint are consistent with the datasheet. No critical symbol or copper-footprint mismatch was found. The main issues are metadata completeness, manufacturer normalization, absent pin descriptions, and an unverified 3D model identity/height.
