XFEB321611-500-0.4A

Overview

The XFEB321611-500-0.4A is a single-line ferrite bead manufactured by XFMRS, designed for surface-mount assembly in the 1206 (3216 Metric) package. It features an impedance of 50 Ohms at 100 MHz and supports a maximum current rating of 0.4 Amperes with a maximum DC resistance of 25 milliohms. The component operates within a temperature range of -55°C to 125°C and holds AEC-Q200 automotive reliability ratings.

Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies
• Designed for compact surface-mount integration in space-constrained circuit layouts
• Complies with AEC-Q200 standards for automotive electronic component reliability

Applications

• Automotive electronics circuits requiring EMI filtering
• High-frequency signal line noise suppression
• Power supply input/output filtering applications

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct impedance and current specifications. Confirm that the 1206 package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your system's environmental conditions. Cross-reference the AEC-Q200 certification status if automotive compliance is mandatory for your project.

Selection Notes

Select this component when a low-profile ferrite bead with moderate current handling capability is required for EMI suppression. The 1206 package offers a balance between size and power dissipation. Consider the 50 Ohm impedance value relative to the target noise frequency spectrum. Verify that the 0.4A current rating exceeds the maximum expected DC load current to prevent saturation or excessive heating during operation.

Part Context

This ferrite bead belongs to the XFEB321611 series from XFMRS, which provides various impedance and current options within the same physical footprint. The series is engineered for consistent performance across different filtering requirements while maintaining standard surface-mount compatibility. This specific variant targets applications needing precise impedance control at 100 MHz with limited current capacity.

Replacement Considerations

Consult official substitution lists for equivalent ferrite beads with matching 1206 dimensions and similar impedance-current profiles. Verify that any alternative component maintains comparable AEC-Q200 qualification if automotive use is intended. Ensure thermal and electrical parameters do not deviate significantly from the original design specifications.
