Procurement Notes

Verify the specific impedance value and current rating against the latest manufacturer datasheet before integration. Confirm that the surface-mount package dimensions align with the PCB footprint design. Ensure the operating temperature range meets the environmental requirements of the final application.

Selection Notes

Select this component when space-constrained designs require effective common-mode noise reduction. The 44 material grade offers high impedance at higher frequencies, suitable for suppressing fast-switching noise. The 5A rating supports moderate power applications without excessive thermal rise.

Part Context

This part belongs to Fair-Rite's SM Beads series, designed specifically for surface-mount technology. It integrates ferrite magnetic properties directly into a compact chip format, eliminating the need for through-hole mounting hardware while maintaining robust EMI performance standards.

Replacement Considerations

Consult official substitution guides for equivalent impedance and current ratings. Verify pin compatibility and physical dimensions before replacing existing components in established designs.
