Arrays, Signal Transformers Procurement Notes

Verify the manufacturer part number against official Eaton documentation to ensure authenticity. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for specific packaging variations such as cut tape or reel options available through authorized distributors. Ensure storage conditions align with the specified humidity sensitivity等级.

Arrays, Signal Transformers Selection Notes

Select this component when dual isolated inductors are required in a compact footprint. Evaluate both parallel and series current ratings against peak load requirements. Consider the low DC resistance for efficiency-critical designs. Verify that the physical dimensions fit within the designated PCB area constraints.

Arrays, Signal Transformers Part Context

This part belongs to the DRQ series of shielded drum core inductors. It shares the standard 12.5x12.5mm package size with other variants in the family but offers unique electrical characteristics tailored for dual-channel power management applications.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes include other Eaton DRQ series parts with similar inductance values. Cross-reference with competitors offering identical 12.5mm square footprints and comparable current ratings if Eaton availability is limited.

Arrays, Signal Transformers FAQ

What is the difference between parallel and series inductance values?

Parallel connection yields 9.654 µH with higher current handling, while series connection results in 38.62 µH with lower current capacity due to increased impedance.

Is the DRQ125-100-R suitable for high-temperature environments?

Yes, it operates reliably within a temperature range of -40°C to +125°C.
