Arrays, Signal Transformers Procurement Notes

Verify the specific package variant (TR, CT, or Digi-Reel) against your assembly requirements. Confirm that the 135 mΩ DCR and 1.4 A parallel current ratings align with your thermal management strategy. Ensure the 7.30mm x 7.30mm footprint matches your PCB land pattern. Cross-reference the WE-DD series datasheet for soldering profile recommendations.

Arrays, Signal Transformers Selection Notes

Select this component when dual-inductor functionality is required in a single package. Choose the parallel configuration for higher current handling up to 1.4 A. Opt for the series configuration if higher inductance values are needed despite lower current capacity. Verify that the 6.8 µH nominal value meets the target impedance requirements of the application circuit.

Arrays, Signal Transformers Part Context
