CTCB1806F-800P

Chip Ferrite Bead Overview

The CTCB1806F-800P is a power line ferrite bead manufactured by Central Technologies in an 1806 (4516 Metric) surface-mount package. It provides an impedance of 80 Ohms at a frequency of 100 MHz. The component supports a maximum current rating of 4 Amperes and features a low DC resistance of 30 milliohms. Designed for single-circuit applications, it serves as a passive filter to suppress electromagnetic interference in power supply lines.

Chip Ferrite Bead Feature Summary

• Multilayer ferrite construction for compact surface-mount integration
• High current handling capability suitable for power line filtering
• Low DC resistance to minimize voltage drop and power loss

Chip Ferrite Bead Applications

• Power supply input filtering
• DC-DC converter output noise suppression
• General-purpose EMI suppression in electronic circuits

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value and current rating against the official Central Technologies datasheet before procurement. Ensure the 1806 package dimensions match the target PCB footprint. Confirm that the 4A current rating meets the operational requirements of the intended circuit to prevent saturation or overheating during use.

Chip Ferrite Bead Selection Notes

Select this component when a high-current ferrite bead with moderate impedance is required for power lines. The 1806 package offers a balance between current capacity and board space. Compare the 80 Ohm impedance at 100 MHz against other available values to ensure effective noise attenuation at the target frequency range without excessive DC resistance.

Chip Ferrite Bead Part Context

This part belongs to the CTCB series of multilayer ferrite chip beads from Central Technologies. The series includes various impedance values and package sizes, such as the CTCB1206F and CTCB0603F variants. These components are designed for general-purpose electromagnetic interference suppression in consumer electronics and industrial equipment.

Chip Ferrite Bead Replacement Considerations

Direct substitutes may include other 1806 ferrite beads with similar 80 Ohm impedance and 4A current ratings. Verify pin compatibility and thermal characteristics before substitution. Alternative manufacturers should provide equivalent impedance-frequency curves and DC resistance specifications.
