BMC2AY0031AN

Chip Ferrite Bead Overview

The BMC2AY0031AN is a single-channel ferrite chip bead from the TE Connectivity BMC series, designed for effective EMI protection in signal lines. Housed in an 0805 (2012 metric) surface-mount package with dimensions of 2.0 mm length, 1.25 mm width, and 1.1 mm height, it provides 31 Ohms impedance at a test frequency of 100 MHz. The component supports a maximum DC current of 300 mA and features a maximum DC resistance of 100 mOhms with a 25% tolerance. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression for high-speed signal lines
• Utilizes a compact 0805 surface-mount footprint for space-constrained PCB layouts
• Engineered for stable performance across a wide industrial temperature range

Chip Ferrite Bead Applications

• High-speed digital signal line filtering
• EMI suppression in portable electronic devices
• Noise reduction in communication interface circuits

Chip Ferrite Bead Procurement Notes

Verify the specific suffix AN against official TE Connectivity documentation to confirm exact impedance characteristics and packaging options. Ensure compatibility with standard reflow soldering profiles for 0805 components. Cross-reference the manufacturer part number BMC2AY0031AN with authorized distributor catalogs to validate active status and RoHS compliance before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a low-impedance path is required for DC signals while attenuating high-frequency noise around 100 MHz. The 300 mA current rating suits moderate power applications, while the 100 mOhm DCR minimizes voltage drop. Consider the 0805 package size for automated assembly compatibility and thermal stability requirements up to 125°C.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the BMC series of passive products by TE Connectivity / Holsworthy. These components are engineered as monolithic structures combining magnetic material and electrodes. The series targets general-purpose EMI filtering needs in consumer electronics and industrial equipment, offering reliable attenuation without introducing significant signal distortion or power loss.

Chip Ferrite Bead Replacement Considerations

Publicly confirmed substitute part numbers for BMC2AY0031AN were not identified in available verified sources. Consult TE Connectivity technical support for qualified alternatives matching the 0805 footprint, 31 Ohm impedance, and 300 mA current rating specifications.
