CTCB1206F-121S

Chip Ferrite Bead Overview

The CTCB1206F-121S is a single-line ferrite bead from Central Technologies, housed in a 1206 (3216 Metric) surface-mount package. It provides an impedance of 120 Ohms at a frequency of 100 MHz. The component has a maximum DC resistance of 200 milliohms and supports a current rating of up to 300 mA.

Chip Ferrite Bead Feature Summary

• Multi-layer chip bead construction for compact circuit integration
• Single-line configuration for power line noise suppression
• Surface-mount design compatible with standard SMT assembly processes

Chip Ferrite Bead Applications

• Power supply input filtering
• High-frequency noise attenuation on data lines
• EMI suppression in portable electronic devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'S' against the manufacturer's official documentation to confirm packaging details and tolerance specifications. Ensure the selected variant matches the required impedance and current ratings for the target application circuit. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Chip Ferrite Bead Selection Notes

Select this component when a low-profile ferrite solution is required for 1206 footprint constraints. Evaluate the 300 mA current rating against peak load requirements to prevent saturation. Confirm that the 120 Ohm impedance at 100 MHz aligns with the targeted noise frequency spectrum for effective EMI reduction.

Chip Ferrite Bead Part Context

This part belongs to the CTCB series of multi-layer ferrite beads manufactured by Central Technologies. These components are designed for general-purpose electromagnetic interference suppression in consumer electronics and industrial equipment where space-saving surface-mount technology is preferred over through-hole alternatives.

Chip Ferrite Bead Replacement Considerations

Publicly confirmed substitute part numbers for this specific model were not identified in available documentation. Verify compatibility with alternative ferrite beads based on identical impedance curves, DC resistance limits, and physical dimensions before substitution.
