Transformer Part Audit


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.
I’ll audit the part metadata, source the official manufacturer documentation if needed, then verify the symbol, footprint, and pin descriptions and correct the Datasheet property if it is missing.
Audit completed against Würth Elektronik’s official 750310742 datasheet.
  • Identity: MPN and 10-pin EP13 package are correct. The description matches the WE‑PoE+ 25 W flyback transformer.
  • Key specs: 38 µH ±10%, 2:1:1.1 turns ratio, 3.5 A typical saturation current, 0.47 µH maximum leakage, 1500 VAC primary/secondary isolation, −40 to +125 °C.
  • Symbol: Pin count and winding assignments are consistent: N1 = 5–6, N2 = 3–2, N3 = 10–1; pins 4 and 7–9 are unused.
  • Datasheet: A datasheet URL was already populated, so no property update was required. Official source: https://www.we-online.com/components/products/datasheet/750310742.pdf
  • Flagged metadata: Part Type is incorrectly/generalized as Ethernet rather than Transformer, package metadata is not explicitly populated, and all pin types are Unspecified with no pin descriptions.
  • Flagged footprint: Pad placement is close but not an exact transcription—2.48 mm versus 2.50 mm pitch and 1.143 mm versus 1.27 mm pad width. The footprint should be corrected to the manufacturer’s recommended land pattern before production.
