BMC1EY0070AN

Chip Ferrite Bead Overview

The BMC1EY0070AN is a single-channel ferrite chip bead from the TE Connectivity BMC series, designed for effective electromagnetic interference (EMI) protection in signal lines. Housed in a compact 0402 (1005 metric) surface-mount package with dimensions of 1 mm x 0.5 mm x 0.5 mm, it provides an impedance of 70 Ohms at a test frequency of 100 MHz. The component supports a maximum DC current of 200 mA and features a maximum DC resistance of 400 mOhms with a 25% tolerance. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides effective EMI protection for signal lines through high-impedance attenuation.
• Utilizes a compact 0402 surface-mount footprint for dense PCB layouts.
• Maintains stable performance across a wide industrial temperature range.

Chip Ferrite Bead Applications

• Signal line filtering in portable electronic devices
• EMI suppression in consumer electronics circuits
• Noise reduction in high-speed data transmission paths

Chip Ferrite Bead Procurement Notes

Verify the specific manufacturer part number BMC1EY0070AN against official TE Connectivity documentation to ensure authenticity. Confirm that the received components match the specified 0402 package and 70 Ohm impedance characteristics. Check for RoHS compliance status as indicated in the official datasheet. Ensure storage conditions adhere to manufacturer guidelines to prevent degradation of the ferrite material or solder terminations before assembly.

Chip Ferrite Bead Selection Notes

Select this component when space-constrained designs require EMI filtering on signal lines carrying up to 200 mA. The 0402 package is suitable for applications where board real estate is limited. Consider the 70 Ohm impedance value relative to the target noise frequencies at 100 MHz. Evaluate the 400 mOhm DC resistance to ensure minimal voltage drop impact on the circuit operation under maximum load conditions.

Chip Ferrite Bead Part Context

This component belongs to the BMC series of ferrite beads manufactured by TE Connectivity Passive Product. The series offers various impedance values and package sizes to address different EMI suppression needs. The BMC1EY0070AN specifically addresses the need for low-profile filtering in modern miniaturized electronics, providing a balance between impedance performance and current handling capabilities in a standard industry footprint.

Chip Ferrite Bead Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative suppliers by matching the 0402 package, 70 Ohm impedance at 100 MHz, and 200 mA current rating specifications strictly.
