Arrays, Signal Transformers Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging when ordering. Confirm that the AEC-Q200 qualification aligns with target automotive standards. Ensure the 165°C operating range meets thermal requirements. Check for RoHS3 compliance if required by regional regulations. Validate pinout compatibility with existing PCB footprints before finalizing procurement.

Arrays, Signal Transformers Selection Notes

Select this component when dual coupled inductors are required in a compact SMD package. The high saturation current supports high-power density designs. Consider the 192 µH series inductance for applications needing higher impedance. The wide temperature range suits harsh automotive environments. Compare DCR values against efficiency targets for specific load conditions.
