Arrays, Signal Transformers Procurement Notes

Verify the exact part number against official Eaton documentation to ensure correct coil configuration and electrical ratings. Confirm package availability and lead times directly with authorized distributors, as manufacturing sources may vary. Check RoHS compliance status and moisture sensitivity levels prior to assembly planning.

Arrays, Signal Transformers Selection Notes

Select this component when dual-inductor functionality is required in a single footprint. Evaluate whether parallel or series connection best suits the target circuit's current and inductance requirements. Ensure the physical dimensions fit the PCB layout constraints and that the thermal characteristics align with the application's operating environment.

Arrays, Signal Transformers Part Context

This part belongs to the DRQ series of shielded drum core inductors from Eaton Electronics. The series is designed for high-power surface-mount applications, offering robust magnetic shielding to minimize electromagnetic interference. The DRQ73-3R3-R specifically provides coupled inductor capabilities within a standard SMD form factor.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes must match the 7.60x7.60mm footprint, 3.54µH/14.16µH inductance values, and current ratings. Verify pin compatibility and shielding effectiveness. Consult Eaton's official cross-reference tools for validated alternatives.
