Confirm RoHS3 compliance status and moisture sensitivity level requirements for your assembly process. Ensure the supplier provides traceability documentation consistent with Eaton Electronics Division standards for quality assurance.

Arrays, Signal Transformers Selection Notes

Select this component when a dual-coil inductor is required for SEPIC or similar topologies. Compare the 47 µH value and 1.41 A saturation current against circuit demands. Consider the 216 mΩ DCR for efficiency calculations. Verify that the 7.60mm footprint fits the PCB layout constraints compared to single-winding alternatives.

Arrays, Signal Transformers Part Context

This part belongs to the DRQ series of shielded drum core inductors. It shares the physical footprint and shielding technology with other DRQ variants but differs in inductance and current ratings. The series is designed for high-power density applications requiring low-profile surface-mount solutions.

Arrays, Signal Transformers Replacement Considerations

Check for direct substitutes within the DRQ series with matching 47 µH inductance. Verify pin compatibility and thermal characteristics if considering alternative manufacturers. Ensure any replacement maintains the same shielding and core material properties.
