CTCB1210F-310S

Chip Ferrite Bead Overview

The CTCB1210F-310S is a surface-mount ferrite bead from Central Technologies, designed for high-frequency noise suppression. It features an impedance of 31 Ohms at 100 MHz and operates with a maximum current rating of 400 mA. The component has a DC resistance of 300 mOhm and utilizes a 1210 (3225 Metric) package size. It is constructed as a single-line device with two terminals, suitable for EMI filtering applications in compact electronic circuits.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression in high-frequency signal paths
• Compact surface-mount design facilitates integration into space-constrained PCB layouts
• Low DC resistance minimizes power loss while maintaining signal integrity

Chip Ferrite Bead Applications

• EMI suppression in high-frequency digital circuits
• Noise filtering in RF signal lines
• Power line conditioning for sensitive ICs

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value of 31 Ohms at 100 MHz against your circuit requirements. Confirm the 400 mA current rating is sufficient for your application to prevent saturation. Ensure the 1225 footprint matches your PCB design. Check RoHS compliance status if required by your manufacturing standards.

Chip Ferrite Bead Selection Notes

Select this component when a low-inductance, high-impedance path is needed for broadband noise attenuation. The 1210 package offers a balance between current handling and board space. Consider the 300 mOhm DC resistance impact on voltage drop if used in power delivery networks. Compare with similar ferrite beads if higher current capacity or different impedance profiles are required.

Chip Ferrite Bead Part Context

This part belongs to the CTCB1210F series of ferrite beads manufactured by Central Technologies. The series includes various impedance values tailored for different frequency ranges. These components are commonly used in consumer electronics, telecommunications, and computer hardware for signal integrity management.

Chip Ferrite Bead Replacement Considerations

Direct substitutes may include other 1210 ferrite beads with 31 Ohms @ 100 MHz impedance and similar current ratings. Verify pin compatibility and thermal characteristics before substitution. Alternative manufacturers may offer comparable performance with slight variations in DC resistance or self-resonant frequency.
