Arrays, Signal Transformers Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Pulse Electronics or authorized distributors before integration. Confirm that the 10% tolerance and 1.8 A current ratings align with your circuit requirements. Ensure the SMD footprint matches your PCB layout constraints. Check for any recent product change notices regarding packaging or material composition updates.

Arrays, Signal Transformers Selection Notes

Select this component when a compact coupled inductor with high current handling is required. The 154.2 uH series inductance provides significant impedance for noise suppression. The low DC resistance minimizes power loss in high-current paths. Consider the 130 C maximum temperature rating for thermal management planning. Ensure the 12.7 mm x 12.7 mm footprint fits within the available board space.
