Arrays, Signal Transformers Procurement Notes

Verify the specific suffix M900 to confirm the tape-and-reel packaging format. Ensure the order matches the exact inductance value of 4.7 µH in parallel configuration. Confirm that the 12.5 mm footprint aligns with the target PCB layout. Validate that the 110 mΩ DC resistance meets the circuit's efficiency requirements. Check for RoHS3 compliance status if required by regional regulations.

Arrays, Signal Transformers Selection Notes

Select this component when a compact, shielded dual-inductor solution is required for automotive or industrial power supplies. The 12.5 mm size offers higher current handling compared to smaller footprints. The magnetic shielding minimizes crosstalk between the two coils. Ensure the operating temperature does not exceed +150°C. Verify saturation current limits against peak load conditions.
