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

Symbol cross-check

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

Footprint cross-check

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

Mismatches / gaps flagged

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.

Overall assessment

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.
