BMC2EY0031AN

Chip Ferrite Bead Overview

The BMC2EY0031AN is a single-channel signal line ferrite bead manufactured by TE Connectivity Passive Product. It features a 1210 (3225 metric) surface-mount package with dimensions of 3.2 mm length, 2.5 mm width, and 1.50 mm height. The component provides an impedance of 31 Ohms at a test frequency of 100 MHz with a 25% tolerance. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 100 mOhms. The device operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Designed for effective electromagnetic interference suppression in signal lines
• Utilizes a compact surface-mount form factor for automated assembly
• Provides stable noise filtering characteristics across a wide operating temperature range

Chip Ferrite Bead Applications

• High-frequency noise suppression in electronic circuits
• Signal line protection in consumer electronics
• EMI filtering in industrial control systems

Chip Ferrite Bead Procurement Notes

Verify the specific package code 'E' corresponds to the 1210 dimension set when sourcing. Confirm that the 500 mA current rating aligns with the target circuit's operational requirements. Ensure compatibility with standard reflow soldering profiles for 1210 components. Check for RoHS compliance documentation if required by local regulations. Validate the 100 mOhm DCR limit against power loss constraints in the design.

Chip Ferrite Bead Selection Notes

Select this component when a 31 Ohm impedance value is required at 100 MHz for signal integrity management. The 1210 package offers a balance between current handling capability and board space efficiency compared to smaller footprints. Consider the 500 mA rating to ensure the bead does not saturate under normal load conditions. The wide temperature range makes it suitable for environments subject to thermal variation.
