Chip Ferrite Bead Procurement Notes

Verify the specific suffix SH1L against official Murata documentation to confirm packaging and tape specifications. Ensure the selected variant matches the required impedance and current ratings for the target application circuit design.

Chip Ferrite Bead Selection Notes

Select this component when a 1206 footprint is required for power line filtering. The 3.5 A current rating makes it suitable for higher power applications compared to standard signal-line beads. Confirm thermal management requirements given the low DC resistance and high current handling capabilities.

Chip Ferrite Bead Part Context

This part belongs to the BLM31 series of ferrite beads, specifically the PG sub-series designed for automotive power applications. It shares the 1206 form factor with other variants but differs in impedance and current handling characteristics based on the internal ferrite material composition.

Chip Ferrite Bead Replacement Considerations

BLM31PG500SZ1L is a confirmed equivalent alternative within the same series offering identical electrical performance.
