Chip Ferrite Bead Procurement Notes

Verify the specific impedance value of 31 Ohms at 100 MHz against your circuit requirements. Confirm the 1206 package dimensions match your PCB footprint. Ensure the 0.5 A current rating meets the operational load. Check for RoHS compliance if required by your manufacturing standards. Validate the supplier's authenticity to avoid counterfeit components.

Chip Ferrite Bead Selection Notes

Select this component when a low DC resistance of 0.15 Ohms is critical to minimize voltage drop. Choose the 1206 package for standard surface-mount assembly compatibility. Consider the 31 Ohm impedance profile for targeted noise filtering at 100 MHz. Evaluate the thermal stability provided by the multilayer construction for reliable performance under soldering conditions.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the FB series from Cal-Chip Electronics, which utilizes multilayer technology for compact EMI suppression. The series is engineered for surface-mount applications, offering robust electrode strength and solderability. These components are designed to replace conventional wire-wound beads, simplifying PCB layout while maintaining effective noise attenuation capabilities.

Chip Ferrite Bead Replacement Considerations

Cross-reference with other 1206 ferrite beads offering similar 31 Ohm impedance at 100 MHz. Verify that substitute parts maintain the same 0.5 A current rating and 0.15 Ohm DC resistance. Ensure physical dimensions and terminal configurations are compatible with existing footprints.
