Arrays, Signal Transformers Procurement Notes

Verify the specific suffix and manufacturer part number against official Eaton documentation to ensure correct electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Cross-reference datasheet parameters such as DCR and current ratings with system design specifications to prevent performance mismatches.

Arrays, Signal Transformers Selection Notes

Select this component when dual independent inductors are required in a compact footprint. Evaluate thermal management needs based on the specified current ratings and ambient operating temperatures. Ensure the chosen connection mode (series or parallel) aligns with the target impedance and current handling requirements of the application circuit.

Arrays, Signal Transformers Part Context

This part belongs to the DRQ series of shielded power inductors from Eaton Electronics. The series is designed for high-current applications requiring low profile and reliable performance. It complements single-coil variants like the DR73 series by offering integrated dual-channel solutions for space-constrained designs.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes include other DRQ series parts with matching inductance and form factor. Verify pinout compatibility and electrical tolerances before replacing. Consult Eaton's official substitution guides for validated alternatives.
