Arrays, Signal Transformers Procurement Notes

Verify the specific suffix (LF) against datasheet requirements to ensure lead-free compliance if necessary. Confirm that the unshielded configuration meets electromagnetic interference constraints for the target application. Validate physical dimensions and weight specifications against mechanical board layout requirements before finalizing procurement decisions.

Arrays, Signal Transformers Selection Notes

Select this component when dual independent inductors are required in a single surface mount footprint. The configurable series/parallel topology allows flexibility in circuit design. Ensure the unshielded nature does not interfere with nearby sensitive components. Verify that the 17 mΩ DC resistance aligns with power loss tolerances in the specific circuit path.

Arrays, Signal Transformers Part Context

Gowanda Electronics specializes in OEM board-level magnetic components, including RF and power inductors. The SMT45A series represents their surface mount toroidal inductor line. This part belongs to the Arrays category, distinct from single fixed inductors.
