CTCB0603F-121S

Chip Ferrite Bead Overview

The CTCB0603F-121S is a multilayer ferrite chip bead from Central Technologies, housed in a 0603 (1608 Metric) package. It exhibits an impedance of 120 Ohms at 100 MHz and a maximum DC resistance of 250 milliohms. The component supports a current rating of 400 mA and is designed for high-quality noise suppression in compact electronic circuits.

Chip Ferrite Bead Feature Summary

• Multilayer ferrite construction for effective high-frequency noise attenuation
• Compact 0603 surface-mount footprint suitable for space-constrained designs
• RoHS compliant manufacturing process

Chip Ferrite Bead Applications

• High-frequency signal line filtering
• Power supply noise suppression
• EMI reduction in portable electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'S' corresponds to the Tape & Reel packaging configuration when ordering. Confirm that the 400 mA current rating meets the operational requirements of the target circuit to prevent saturation or excessive heating during procurement validation.

Chip Ferrite Bead Selection Notes

Select this component when a low-profile solution with moderate current handling is required. Ensure the 120 Ohm impedance at 100 MHz aligns with the noise spectrum of the application. Verify that the 250 milliohm DC resistance does not introduce unacceptable voltage drop in the power path.

Chip Ferrite Bead Part Context

This part belongs to the CTCBF series of ultra multilayer ferrite beads. It is manufactured by Central Technologies, formerly CT Magnetics. The series offers various impedance values within the standard 0603 case size to address different filtering needs in consumer and industrial electronics.

Chip Ferrite Bead Replacement Considerations

Cross-reference with other 0603 ferrite beads offering 120 Ohms @ 100 MHz and similar current ratings. Verify pin compatibility and impedance tolerance specifications before substituting with components from alternative manufacturers.
