XFEB100505-121

Overview

The XFEB100505-121 is a single-line ferrite bead in a 0402 (1005 metric) surface-mount package. It exhibits an impedance of 120 Ohms at 100 MHz and carries AEC-Q200 ratings. Specific current and resistance variants include the -1.5A suffix with a 1.2A max current rating and 90mOhm DCR, and the -0.45A suffix with a 450mA max current rating and 240mOhm DCR.

Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies.
• Designed for compact surface-mount integration within dense circuit layouts.
• Complies with automotive reliability standards for enhanced durability.

Applications

• High-frequency noise filtering in electronic circuits
• Signal integrity enhancement in data lines
• Power supply decoupling applications

Procurement Notes

Verify the complete part number including the current rating suffix, as specifications vary significantly between variants. Confirm AEC-Q200 compliance requirements if used in automotive contexts. Ensure the 0402 footprint matches the design layout constraints before ordering.

Selection Notes

Select based on required DC resistance and current handling capabilities. Higher current ratings correlate with lower DC resistance but may require careful thermal management. The 120 Ohm impedance value targets specific frequency ranges for effective noise attenuation.

Part Context

This component belongs to the XFEB100505 series of chip ferrite beads manufactured by XFMRS. The series offers various impedance and current options within a standardized small outline package, suitable for modern miniaturized electronics.

Replacement Considerations

Direct substitutes must match the 120 Ohm @ 100 MHz impedance and 0402 footprint. Verify equivalent current ratings and DC resistance values to ensure circuit performance compatibility without modification.
