Arrays, Signal Transformers Procurement Notes

Verify the specific datasheet version for the DRQ125-221-R to confirm dual-winding parameters, as single-winding variants exist in the same series. Ensure compatibility with automated pick-and-place equipment due to the non-standard package outline. Confirm RoHS compliance status for your region's regulatory requirements before finalizing procurement orders.

Arrays, Signal Transformers Selection Notes

Select this component when dual isolated or coupled windings are required within a standard 12.5mm footprint. Compare saturation current ratings against peak load conditions to prevent performance degradation. Consider the thermal dissipation characteristics of the shielded drum core if operating near the upper temperature limit.

Arrays, Signal Transformers Part Context

This part belongs to the DRQ series of high-power shielded drum core inductors from Eaton Electronics. The series is designed for applications requiring high current handling and low profile. The DRQ125-221-R specifically offers dual windings, distinguishing it from single-winding counterparts like the DRA or DR series.
