XFEB201209-121-3A

Overview

The XFEB201209-121-3A is a single-line ferrite bead chip manufactured by XFMRS in an 0805 (2012 Metric) package. It exhibits an impedance of 120 Ohms at 100 MHz with a tolerance of ±25%. The component has a maximum DC resistance of 0.040 Ohms and supports a current rating of 3000 mA.

Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies
• Designed for surface mount integration into compact electronic circuits
• Constructed to handle high continuous current loads without saturation

Applications

• High-current power line filtering in portable electronics
• Noise suppression on data lines within communication modules
• EMI mitigation in automotive infotainment systems

Procurement Notes

Verify the exact suffix against manufacturer documentation to confirm current rating and impedance specifications. Ensure the 0805 footprint matches the target PCB layout. Confirm RoHS compliance status if required by regulatory standards. Cross-reference the part number with official XFMRS catalogs to avoid substitution errors.

Selection Notes

Select this component when high current handling capacity is required alongside moderate noise attenuation. The low DC resistance minimizes voltage drop in power paths. Evaluate thermal performance under peak load conditions. Ensure the operating frequency aligns with the 100 MHz impedance specification for effective filtering.

Part Context

This ferrite bead belongs to the XFEB201209 series, which offers various current ratings and impedance values within the same physical footprint. The series is designed for applications requiring robust EMI suppression in space-constrained environments. Different suffixes denote variations in electrical parameters while maintaining consistent mechanical dimensions.

Replacement Considerations

Consult XFMRS official documentation for direct cross-references. Verify that substitute components match the 0805 package, 120 Ohm impedance, and 3000 mA current rating. Ensure equivalent DC resistance and temperature stability characteristics.
