Arrays, Signal Transformers Procurement Notes

Verify the specific package variant required, as distribution channels may list Cut Tape, Reel, or Digi-Reel formats under distinct ordering suffixes. Confirm that the dual-coil array specification aligns with the target schematic design, particularly regarding the shared magnetic core characteristics and mutual inductance effects inherent to this series. Ensure thermal management strategies account for the specified operating temperature limits.

Arrays, Signal Transformers Selection Notes

Select this component when a shielded dual-inductor solution is required for space-constrained designs. The choice between parallel and series operation depends on the desired current handling versus inductance value. Verify that the physical footprint of 12.50 mm square fits the PCB layout constraints. Consider the lower DC resistance in parallel mode for higher efficiency applications requiring greater current capacity.
