Fixed Inductors Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's official datasheet to confirm packaging details and tape-and-reel specifications. Ensure that the requested quantity aligns with standard reel sizes defined by Bourns Inc. Cross-reference the RoHS compliance status with the latest regulatory documentation prior to finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a compact, shielded inductor is required for power management applications. The 12 μH value and 1.4 A current rating suit moderate-power conversion stages. Consider the 90 mΩ DCR for efficiency calculations and verify thermal performance within the specified -40°C to +125°C operating range for the target environment.

Fixed Inductors Part Context

This part belongs to the SRR5028 series of shielded wirewound inductors manufactured by Bourns Inc.
