• Provides effective electromagnetic interference suppression through controlled impedance characteristics
• Designed for compact surface-mount integration within standard PCB layouts
• Maintains stable electrical performance under specified direct current loads

Applications

• High-frequency noise filtering in portable electronic devices
• Signal integrity enhancement in data transmission lines
• Power supply line conditioning for sensitive integrated circuits

Procurement Notes

Verify the specific suffix code to confirm the rated current and DC resistance values, as these parameters vary across the XFEB201209 series. Ensure the selected variant matches the circuit's current requirements and impedance specifications exactly. Cross-reference the manufacturer's official datasheet for the precise part number to avoid confusion with similar models that share the same physical footprint but differ electrically.

Selection Notes

Select this component based on the required 30 Ohm impedance at 100 MHz and the 400 mA current handling capability. Evaluate the 0805 package size against available board space constraints. Consider the low DC resistance value to minimize voltage drop and power dissipation in the target application circuit. Confirm compatibility with standard reflow soldering processes used in the manufacturing environment.

Part Context

This component belongs to the XFEB201209 series of ferrite beads from XFMRS Inc. The series offers various current ratings and resistance values while maintaining consistent impedance profiles. These components are engineered for use in modern electronics where space efficiency and reliable noise suppression are critical design factors.

Replacement Considerations

Direct substitutes within the same series include XFEB201209-300-3A and XFEB201209-300-6A. Verify that alternative parts match the 30 Ohm impedance requirement and ensure their current ratings exceed the application needs. Physical compatibility is maintained due to the shared 0805 package dimensions.
