BMC1EY0030AN

Chip Ferrite Bead Overview

The BMC1EY0030AN is a single-line ferrite bead chip from the BMC series by TE Connectivity Passive Product. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 30 Ohms at 100 MHz and has a maximum DC resistance of 200 mOhms. It supports a rated current of 300 mA and operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference (EMI) protection through high-frequency signal attenuation.
• Designed for compact surface-mount applications using a standard 0402 footprint.
• Constructed for reliable operation across a wide industrial temperature range.

Chip Ferrite Bead Applications

• High-speed data line filtering in portable electronic devices
• Power supply noise suppression on printed circuit boards
• Signal integrity management in communication modules

Chip Ferrite Bead Procurement Notes

Verify the specific suffix AN against the manufacturer's latest datasheet to confirm tolerance and termination specifications. Confirm RoHS compliance status directly with the supplier or original manufacturer documentation prior to integration. Ensure the ordering part number matches the required impedance and current ratings for the target circuit design.

Chip Ferrite Bead Selection Notes

Select this component when a low-impedance path is required for signals up to 100 MHz while maintaining a small board footprint. The 300 mA current rating suits moderate power distribution lines. Compare against higher impedance variants if stronger attenuation is needed, or larger packages if higher current handling is necessary.

Chip Ferrite Bead Part Context

This component belongs to the BMC series of ferrite beads, which are widely used for EMI suppression in consumer and industrial electronics. The 0402 package size allows for high-density PCB layouts. TE Connectivity Passive Product manufactures these components to meet strict reliability standards for mass-produced electronic assemblies.

Chip Ferrite Bead Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult official cross-reference guides or contact the manufacturer for verified alternatives that match the 30 Ohm @ 100 MHz impedance and 0402 package constraints.
