Procurement Notes

Verify the specific suffix Y0 against official Fair-Rite documentation to confirm packaging and material specifications. Ensure the selected variant matches the required impedance curve and current handling capabilities for the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a 0402 footprint for high-frequency noise attenuation. Evaluate the 200 mA current limit against peak load requirements to prevent saturation. Confirm that the 120 ohm impedance profile aligns with the specific frequency spectrum of the interference signals present in the application.

Part Context

This part belongs to the Fair-Rite series of cost-effective multilayer chip beads engineered to suppress conducted electromagnetic interference. These components utilize specialized ferrite materials to provide effective signal line filtering while maintaining small physical profiles suitable for dense printed circuit board layouts.

Replacement Considerations

Direct substitutes must match the 0402 package, 120 ohm impedance at 100 MHz, and 200 mA current rating. Verify material composition and thermal characteristics to ensure equivalent performance in the original application environment.
