BMC2AY0300AN

Chip Ferrite Bead Overview

The BMC2AY0300AN is a single-line ferrite chip bead from the BMC series by TE Connectivity Passive Product. It provides an impedance of 300 Ohms at 100 MHz with a maximum DC resistance of 250 mOhms and a rated current of 300 mA. The component utilizes a 0805 (2012 metric) surface-mount package, measuring 2.00 mm in length, 1.25 mm in width, and 0.9 mm in height. It operates within a temperature range of -55°C to +125°C and features a 25% impedance tolerance.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference (EMI) protection through high-frequency signal attenuation.
• Designed for surface-mount assembly using standard SMD/SMT termination types.
• Constructed as a single-channel component for integration into compact circuit layouts.

Chip Ferrite Bead Applications

• High-speed data line filtering
• Power supply noise suppression
• General-purpose EMI suppression in consumer electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'A' indicates the Gen C generation variant when sourcing replacements. Confirm RoHS compliance status via the official datasheet before finalizing procurement decisions. Ensure the selected packaging format matches production requirements, as availability may vary between cut tape and reel options depending on the distributor.

Chip Ferrite Bead Selection Notes

Select this component when a 300 Ohm impedance at 100 MHz is required for signal integrity management. The 300 mA current rating suits moderate power applications, while the low DCR minimizes voltage drop. The 0805 footprint allows for dense PCB routing compared to larger packages, making it suitable for space-constrained designs requiring reliable noise filtration.

Chip Ferrite Bead Part Context

This part belongs to the BMC series of ferrite beads, which are engineered for general-purpose noise suppression. The BMC2AY0300AN shares the standard 0805 dimensions with other variants in the family but differs in impedance and current handling capabilities. It serves as a passive filter element distinct from inductors or resistors, specifically optimized for broadband frequency attenuation.
