Arrays, Signal Transformers Procurement Notes

Verify the specific datasheet version for the 74489430180 to confirm exact tolerance and thermal characteristics. Ensure compatibility with automated pick-and-place equipment due to the SMD form factor. Cross-reference pinout diagrams during PCB layout to prevent orientation errors. Confirm RoHS compliance status through official manufacturer documentation before final integration.

Arrays, Signal Transformers Selection Notes

Select this component for applications demanding tight magnetic coupling and minimal electromagnetic interference. The NiZn core material provides stability across varying frequencies. Evaluate the trade-off between series and parallel current ratings based on the specific circuit topology requirements. Ensure the operating temperature range aligns with the system's environmental conditions.

Arrays, Signal Transformers Part Context

This part belongs to the WE-TDC series of shielded coupled inductors. It is distinct from other Wurth inductor families like WE-CF or WE-LPCC by its specific dual-coil array configuration and NiZn core composition. The series is engineered for high-frequency performance and low profile requirements in modern electronic assemblies.

Arrays, Signal Transformers Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Engineers should evaluate other WE-TDC variants with similar inductance values if exact replacement is unavailable. Verify mechanical footprint and electrical parameters against alternative components to ensure functional equivalence.
