Arrays, Signal Transformers Procurement Notes

Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure compatibility with your circuit requirements. Confirm that the package type and pinout match your PCB footprint exactly. Check for any recent Product Change Notifications (PCN) regarding material or manufacturing location updates. Ensure that the supplier provides valid RoHS compliance certificates as required by your regulatory standards.

Arrays, Signal Transformers Selection Notes

Select this component when a compact, high-current coupled inductor is required for SEPIC or Buck-Boost applications. The 2.4 uH value and 6 A current rating suit moderate power levels. Consider the 12.5 mm x 12.5 mm footprint for space-constrained designs. Evaluate the thermal performance at the target operating temperature to ensure the 125°C limit is not exceeded under load conditions.

Arrays, Signal Transformers Part Context

This component belongs to the WE-DD series of shielded power inductors from Würth Elektronik. The series is characterized by its low profile and high saturation current capabilities, making it suitable for dense PCB layouts. The WE-DD line typically utilizes ferrite cores to provide stable inductance values across varying current loads.

Arrays, Signal Transformers Replacement Considerations

Consult official Wurth Elektronik cross-reference lists for verified substitutes. Generic equivalents may differ in saturation current or DCR specifications.
