Part Review Datasheet
Thought for 52 sec
I found the official TDK VLCF5020-1 series datasheet URL and am checking whether the part record already exposes it before applying any update.
Worked for 4 mins 28 sec
The part record had an empty Datasheet URL, so I set it to the official TDK PDF and am now doing the final symbol/footprint/spec comparison.

Part Review - VLCF5020T-100M1R1-1
Review date: 2026-07-21 Official TDK product page found the datasheet for VLCF5020T-100M1R1-1.
Completed the part review and set the part/project Datasheet URL to the official TDK PDF. The symbol and footprint are electrically/mechanically consistent with the datasheet; main flagged issues are metadata polish: sparse description, no explicit package/case property observed, optional pin descriptions missing, and non-inspectable 3D model size metadata.
Full details are in Part Review - VLCF5020T-100M1R1-1. Suggested next steps: update the description/package metadata, optionally add terminal descriptions, and visually confirm the STEP model alignment.

Schematic symbol and pins
Observed symbol/terminal data:
- Terminal
1: passive, pin number1, symbol position on the left. - Terminal
2: passive, pin number2, symbol position on the right. - No functional pin descriptions were set on the terminals.
Cross-check:
- A two-terminal passive symbol is electrically correct for this non-polarized inductor.
- Passive pin type on both terminals is correct.
- The datasheet does not provide special functional pin names or polarity; lack of detailed pin descriptions is not an electrical mismatch.
- If desired for library polish, pin descriptions can be set to simple labels such as
Terminal 1andTerminal 2.
Footprint cross-check
Observed footprint data:
- 2 custom SMD copper pads on top layer.
- Pad 1 center: y = -1.7 mm; Pad 2 center: y = +1.7 mm.
- Each copper pad spans about 4.90 mm in X and 2.10 mm in Y.
- Inner pad-to-pad gap is about 1.30 mm.
- Copper pad shape includes chamfered 45°-style ends.
- Solder mask shape is expanded by about 0.10 mm around copper.
- Fab outline is about 5.0 mm × 5.3 mm.
- Courtyard is about 5.5 mm × 6.0 mm.
- STEP model asset is present:
VLCF5020T-100M1R1-1.step.
Datasheet / TDK land pattern values extracted:
- Recommended land pattern includes 4.9 mm pad length, 2.1 mm pad dimension, 1.3 mm gap, 45° feature, and 3.0 mm/1.2 mm auxiliary dimensions in the drawing.
- Shape/dimensions drawing shows 5.0 ±0.2 mm body dimensions, 5.3 mm max overall dimension, and 2.0 mm max height.
Footprint verdict:
- Copper pad size, pad spacing, and chamfering match the official TDK recommended land pattern.
- Fab outline 5.0 × 5.3 mm matches the datasheet body/overall dimensions as interpreted from the shape drawing.
- No footprint pad-count mismatch found.
Mismatches / issues flagged
-
Datasheet URL was missing
- Status: Fixed. The part/project Datasheet URL property now points to the official TDK PDF.
-
Description is sparse / not a clean part description
- Current description includes
N/Aand manufacturer-recommendation text rather than a concise part description. - Recommended description:
TDK VLCF5020-1 shielded wound ferrite SMD power inductor, 10 µH ±20%, 1.13 A Isat, 5.0 × 5.0 × 2.0 mm.
- Current description includes
-
Explicit package/case property not observed
- The footprint and 3D model indicate the correct physical package, but the part properties inspected did not show a clear package/case field.
- Recommended package/case text:
VLCF5020-1, 5.0 × 5.0 × 2.0 mm SMD.
-
Pin descriptions are absent
- Not an electrical mismatch because the datasheet does not define polarity or functional pin names.
- Optional library-quality improvement: set pin descriptions to
Terminal 1andTerminal 2.
-
3D model metadata dimensions were not inspectable
- A STEP model is present, but the layout node reported computed
packageSize: {x: 0, y: 0, z: 0}for the model/footprint metadata. - Visual/model geometry may still be correct; this only means the inspected metadata did not expose actual model dimensions.
- A STEP model is present, but the layout node reported computed
Overall verdict
The part is substantially correct for the TDK
VLCF5020T-100M1R1-1: MPN/manufacturer, two passive terminals, and the SMD land pattern align with the official TDK datasheet. The main corrections needed are metadata polish: the datasheet URL has been fixed, while the description, explicit package/case field, optional pin descriptions, and model-dimension metadata could be improved.Source reviewed
