Chip Ferrite Bead Procurement Notes

Verify the specific part status, as this component may be listed as obsolete in certain distributor catalogs. Confirm current availability directly with authorized suppliers or Central Technologies. Ensure that the 1812 package dimensions and 70 Ohm impedance specifications align precisely with your circuit design requirements before finalizing procurement decisions.

Chip Ferrite Bead Selection Notes

Select this component when a 1812 footprint is required for space-constrained designs. The 70 Ohm impedance at 100 MHz defines its filtering characteristics. Consider the single-line topology for simple noise suppression needs. Verify thermal and current ratings against application demands to ensure reliable operation under expected load conditions.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the CTCBF series from Central Technologies. It shares the 1812 package form factor with other variants in the lineup, such as the CTCB1812F-125S. The series focuses on providing multi-layer ferrite solutions for surface-mount applications requiring specific impedance profiles for EMI control.

Chip Ferrite Bead Replacement Considerations

Direct substitutes must match the 1812 package, single-line configuration, and similar impedance characteristics. Cross-reference with other manufacturers offering 70 Ohm @ 100 MHz ferrite beads in 1812 packages. Verify mechanical and electrical compatibility before substitution.
