Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the package dimensions and terminal configuration match the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when designing circuits requiring EMI suppression for high-speed digital interfaces. The 67 Ohm impedance offers effective filtering for the specified protocols. Consider the 1.2 A current rating to ensure adequate headroom for power delivery or signal line requirements. Evaluate the unshielded construction against nearby sensitive components to prevent potential coupling issues in dense layouts.
Part Context
This component belongs to the Chilisin RF inductor series produced under license for Pulse Electronics. It is categorized as a ferrite bead or common mode choke designed specifically for signal line protection. The product falls under the broader category of passive electronic components used for electromagnetic interference mitigation in consumer electronics and computer peripherals.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative common mode chokes based on impedance, current rating, and physical dimensions if sourcing constraints exist.
