BMC1EY0120AG

Chip Ferrite Bead Overview

The TE Connectivity BMC1EY0120AG is a single-channel ferrite chip bead designed for effective electromagnetic interference (EMI) protection in surface-mount applications. Housed in a compact 0402 (1005 metric) package with dimensions of 1 mm length, 0.5 mm width, and 0.60 mm height, it operates within a temperature range of -55°C to +125°C. The component exhibits an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current rating of 1.5 A and maintains a maximum DC resistance of 75 mOhms.

Chip Ferrite Bead Feature Summary

Chip Ferrite Bead Procurement Notes

Verify the specific suffix AG against official TE Connectivity documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with standard reflow soldering profiles for 0402 components. Cross-reference the manufacturer part number BMC1EY0120AG with authorized distributor catalogs to validate authenticity and traceability before integration into production schedules.

Chip Ferrite Bead Selection Notes

Select this component when a low DC resistance of 75 mOhms and a high current handling capability of 1.5 A are required alongside significant attenuation at 100 MHz. The 0402 package size is suitable for space-constrained designs where standard ferrite beads may not fit. Confirm that the 25% impedance tolerance aligns with the specific noise suppression requirements of the target signal path.
