Procurement Notes

Verify the exact part number suffix against official manufacturer documentation to ensure correct physical dimensions and impedance characteristics. Confirm RoHS compliance status and packaging specifications directly with the supplier or authorized distributor prior to ordering. Cross-reference internal and external measurements to guarantee fitment within the intended assembly constraints.

Selection Notes

Select this component when a low-profile solid ferrite core is required for flat ribbon cables. Ensure the target cable width does not exceed the maximum accommodation limit. Verify that the 151 ohm impedance at 100MHz aligns with the specific frequency range of the noise sources present in the application environment.

Part Context

This component belongs to the FerriShield series of solid bar ferrites manufactured by Leader Tech Inc. These products are engineered for EMI shielding in electronic enclosures and interconnect cables. The series offers various sizes to accommodate different cable widths while maintaining a consistent low-profile form factor for space-constrained designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's catalog for alternative sizes within the same series if dimensional or impedance requirements differ.
