Arrays, Signal Transformers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging options such as tape and reel or cut tape. Confirm that the RoHS3 compliance status matches your environmental requirements. Cross-reference the electrical parameters with your schematic to ensure compatibility with system voltage and current limits before finalizing procurement orders.

Arrays, Signal Transformers Selection Notes

Select this component when dual inductors are required in a compact footprint to save board space. Choose the series connection for higher inductance needs or parallel for lower resistance and higher current handling. Ensure the operating temperature range of -40°C to 125°C aligns with the application environment. Verify that the physical dimensions fit within the designated land pattern area.

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 applications requiring robust magnetic shielding. The DRQ73-680-R specifically utilizes a two-coil architecture within a standard 0703 metric footprint, distinguishing it from single-coil variants in the broader DR family.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes must match the 68.91 µH parallel inductance and 7.60mm x 7.60mm footprint. Verify equivalent DCR and saturation current ratings. Check for identical pin configurations and shielding requirements to maintain circuit performance without redesign.
