Chip Ferrite Bead Procurement Notes

Verify RoHS compliance status directly with the manufacturer or authorized distributor, as documentation indicates this requires specific confirmation. Ensure the ordering part number matches the exact suffix requirements for your production line specifications before finalizing procurement orders to avoid compatibility issues.

Chip Ferrite Bead Selection Notes

Select this component when a 120 Ohm impedance at 100MHz is required for EMI suppression. The 200mA current rating limits its use to low-power signal paths rather than high-current power delivery lines. Consider physical size constraints and mounting orientation during PCB layout design to ensure adequate clearance for soldering.

Chip Ferrite Bead Part Context

This inductor belongs to the CIM03 series, which focuses on small-footprint magnetic components. Samsung Electro-Mechanics utilizes advanced coil winding techniques to achieve stable inductance values in miniature packages. The series supports the industry trend toward miniaturization in portable electronic devices and IoT sensors.

Chip Ferrite Bead Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching impedance, current rating, and package dimensions with alternative manufacturers.
