• Signal processing applications requiring dual coils

Arrays, Signal Transformers Procurement Notes

Verify the specific datasheet version for the DRQ73-220-R, as manufacturer documentation may list varying saturation currents or resistance values depending on the revision. Confirm that the four-terminal package matches your PCB footprint requirements before finalizing procurement decisions.

Arrays, Signal Transformers Selection Notes

Select this component when a compact, shielded dual-coil solution is required for power management. The 22 µH value suits intermediate frequency filtering. Ensure the 1.67 A saturation rating aligns with peak load conditions to prevent inductance collapse.

Arrays, Signal Transformers Part Context

This part belongs to the DRQ series of high-power chokes. It is distinct from single-winding variants like the HCM series due to its dual-coil structure. The DRQ series is designed for applications needing isolated or coupled inductance in a small surface-mount form factor.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes are not explicitly confirmed in public data. Evaluate other DRQ series parts with identical 22 µH ratings and compatible physical dimensions for potential cross-referencing.
