Fixed Inductors Procurement Notes

Verify the specific suffix 'EK' against official datasheets to confirm exact electrical tolerances and thermal ratings. Ensure compatibility with peak reflow temperatures specified by the manufacturer. Confirm that the shielded design aligns with electromagnetic interference requirements for the target application environment.

Fixed Inductors Selection Notes

Select this component when a compact footprint is required alongside moderate current handling capabilities. The shielded architecture makes it suitable for noise-sensitive environments. Evaluate the 50.1 mΩ DCR against efficiency targets and compare the 4.2 A rating against peak load demands to ensure adequate margin.

Fixed Inductors Part Context

This part belongs to the IHLP® 2020AB series, which provides low DCR per microhenry values for its package size. The series is engineered for high transient current handling and offers excellent temperature stability. It serves as a solution for thin, high-current power supplies and battery-operated devices requiring reliable surface-mount inductance.

Fixed Inductors Replacement Considerations

Cross-reference with other IHLP-2020BZ variants sharing identical 2.2 µH inductance and similar current ratings. Verify physical dimensions and terminal configurations to ensure mechanical fit. Check if alternative suffixes offer different tolerance levels or thermal characteristics while maintaining the same form factor.
