• Utilizes a compact 0805 surface-mount footprint for space-constrained designs
• Offers stable performance across a wide industrial temperature range

Chip Ferrite Bead Applications

• High-speed digital signal line filtering
• Power supply noise attenuation in compact electronics
• EMI suppression in mobile communication devices

Chip Ferrite Bead Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct packaging and variant selection. Confirm that the 0805 package dimensions align with the target PCB land pattern. Check RoHS compliance status if required by project specifications. Ensure the selected distributor source matches the official TE Connectivity manufacturing origin to guarantee component authenticity and traceability.

Chip Ferrite Bead Selection Notes

Select this component when a 220 Ohm impedance at 100 MHz is required for EMI filtering in an 0805 package. The 300 mA current rating suits moderate power applications. Compare the 250 mOhm DCR against circuit loss requirements. Consider alternative BMC series variants like BMC1EY or BMC1HY if smaller 0402 or 0201 footprints are necessary for the design.

Chip Ferrite Bead Part Context

This part belongs to the TE Connectivity BMC series of ferrite beads, which are widely used for high-frequency noise suppression. The series offers various package sizes including 0201, 0402, 0603, and 0805, allowing designers to choose based on space and current constraints while maintaining consistent electrical characteristics across the family.

Chip Ferrite Bead Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the official TE Connectivity datasheet for cross-reference information or equivalent components from other manufacturers that match the 0805 footprint, 220 Ohm impedance, and 300 mA current rating.
