Part Datasheet Review and Update
Thought for 2 mins 48 sec
Done.
I updated the part’s Datasheet URL to the exact official Würth PDF for 74438356220:
https://www.we-online.com/components/products/datasheet/74438356220.pdf
I followed the standard part-project audit flow: verify the datasheet source first, then compare pin count and metadata against the datasheet, with exact pin-count matching required and passive parts mainly needing correct pin numbers, pin types, and short pin descriptions rather than IC-style grouping fields
Summary of what I found
Key specs from the official datasheet
Table
| Field | Value |
|---|---|
| MPN | 74438356220 |
| Manufacturer | Würth Elektronik |
| Part type | Shielded SMT power inductor / metal alloy power inductor |
| Inductance | 22 µH |
| Tolerance | ±20% |
| Rated current | 1.85 A max |
| Saturation current | 1.1 A typ @ 10% drop, 2.45 A typ @ 30% drop |
| DCR | 250 mΩ typ, 280 mΩ max |
| SRF | 11 MHz typ |
| Max operating voltage | 80 V DC max |
| Operating temperature | -40 °C to +125 °C |
| Package / size | 4020, about 4.0 × 4.0 × 2.0 mm family size; exact body drawing around 4.1 × 4.1 × 2.1 mm max |
| Pin count | 2-pin passive inductor |
Table
| Check | Result |
|---|---|
| Terminal count | Pass - project has 2 terminals, datasheet indicates 2 terminals |
| Pin numbers | Pass - current pins are 1 and 2 |
| Pin type | Pass - both are Passive, which matches an inductor |
| Pin descriptions | Mismatch / incomplete - no pin descriptions are currently set |
| Terminal names/designators | Potential mismatch / incomplete - terminals appear unnamed/generic rather than explicitly labeled |
Table
| Check | Result |
|---|---|
| Pad count | Pass - footprint has 2 pads |
| Footprint family | Pass - assets indicate a WE-MAPI_4020 footprint and matching 3D model |
| Body size alignment | Likely pass - project footprint naming matches the datasheet’s 4020 size class |
| Exact land-pattern dimensions | Not fully verifiable from exposed layout data - the project index confirms the 2-pad footprint, but does not expose exact per-pad XY/size values for a strict numerical overlay against the datasheet |
- Missing metadata
- Manufacturer Name is not currently populated in project properties.
- Part Type is not currently populated in project properties.
- Package or Case Code is not currently populated in project properties.
- Missing symbol metadata
- Pin descriptions are missing for both terminals.
- Description gap
- I could not confirm a populated project description from the indexed project data.
- Footprint verification limitation
- I could confirm the footprint family and 2-pad structure, but not exact pad geometry from the exposed layout fields.
- The part project is structurally consistent with the datasheet for a 2-pin passive inductor.
- The symbol is electrically reasonable.
- The footprint appears to be the correct family/size, but I can only call the exact pad geometry check partial, not fully proven.
- The main issues are missing metadata, not obvious electrical or pin-count errors.
If you want, I can next fill in the missing part metadata and add short pin descriptions for the two terminals.
