Arrays, Signal Transformers Procurement Notes

Verify the manufacturer part number DRQ74-471-R against official Eaton documentation to ensure authenticity. Confirm that the specific order suffix matches the required packaging format, such as tape and reel or cut tape, as these affect handling procedures. Check current RoHS3 compliance status and moisture sensitivity level before integration into production schedules.

Arrays, Signal Transformers Selection Notes

Select this component when dual-inductor functionality is required within a compact footprint. The shielded design suits applications sensitive to magnetic coupling. Ensure the parallel or series configuration aligns with the target impedance and current requirements of the specific power stage or signal path.

Arrays, Signal Transformers Part Context

This part belongs to the DRQ series of shielded drum core inductors from Eaton Electronics Division. The series is designed for high-power surface-mount applications requiring reliable performance in constrained spaces. It shares physical dimensions with other variants in the DRQ family but differs in electrical characteristics based on coil winding specifications.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes include DRQ73-471-R and DRQ74-101-R, though electrical parameters differ. Verify pin compatibility and thermal performance before swapping.
