Chip Ferrite Bead Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variations may exist between tape-and-reel and bulk formats. Confirm that the manufacturer designation matches Central Technologies or CT Magnetics to avoid counterfeit components. Cross-reference the full part number against official distributor catalogs to validate availability and lead times prior to finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when circuit requirements demand 300 Ohms impedance at 100 MHz with a 2A current capacity. Ensure the PCB layout accommodates the 0805 package dimensions. Verify that the operating temperature range aligns with system specifications. Consider the 80mOhm DC resistance impact on voltage drop within the power path during initial design validation.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the CTCB series from Central Technologies, designed for general-purpose electromagnetic interference suppression. The series utilizes multi-layer ceramic technology to achieve consistent impedance characteristics across various frequencies. These components are widely utilized in portable devices and industrial equipment where size efficiency and noise reduction are critical design parameters.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other 0805 ferrite beads with matching 300 Ohm @ 100 MHz impedance and 2A current ratings. Verify pin compatibility and physical dimensions before substitution. Check datasheets for equivalent DC resistance and impedance curves to ensure identical filtering performance in the target application.
