XFEB100505-121-0.45A

Overview

The XFEB100505-121-0.45A is a ferrite bead component manufactured by XFMRS Inc., designed for high-frequency noise suppression in electronic circuits. It features a 120 Ohm impedance rating at 100 MHz, providing effective attenuation of electromagnetic interference (EMI) and radio frequency interference (RFI). The device is housed in a compact 0402 (1005 Metric) surface-mount package, suitable for space-constrained applications. It supports a maximum current rating of 0.45 Amperes with a low DC resistance characteristic to minimize power loss in the signal path.

Feature Summary

• Provides high-frequency noise filtering through significant impedance at 100 MHz
• Compact 0402 surface-mount footprint for dense PCB layouts
• Low DC resistance to maintain signal integrity under load

Applications

• High-speed digital signal line filtering
• Power supply input/output noise suppression
• RF circuit interference mitigation

Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Ensure the selected variant matches the required current rating and impedance profile for the target application. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component based on its 120 Ohm impedance at 100 MHz and 0.45 A current handling capability. Consider the 0402 package size for board space limitations. Evaluate the DC resistance impact on the circuit's power budget. Ensure compatibility with standard surface-mount reflow soldering processes used in the manufacturing assembly line.

Part Context

This part belongs to the XFEB100505 series of ferrite beads from XFMRS Inc. The series offers various impedance values within the same 0402 package form factor. These components are passive devices used primarily for EMI suppression in modern electronics where small form factors and reliable noise performance are critical requirements.

Replacement Considerations

Consult the official XFMRS catalog for direct substitutes with identical impedance and current ratings. Verify that any alternative component maintains the same 0402 package dimensions and thermal characteristics to ensure mechanical fit and reliability without redesigning the PCB layout.
