CTCB1812F-700P

Chip Ferrite Bead Overview

The CTCB1812F-700P is a single-line power line ferrite bead manufactured by Central Technologies in an 1812 (4532 Metric) surface-mount package. It provides an impedance of 70 Ohms at 100 MHz with a maximum DC resistance of 30 mΩ and supports a current rating of 6 A.

Chip Ferrite Bead Feature Summary

• Single-line configuration for power line noise suppression
• High current handling capability suitable for power applications
• Surface-mount design for automated assembly

Chip Ferrite Bead Applications

• Power line filtering in electronic circuits
• Noise suppression on high-current traces
• EMI reduction in power supply inputs

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'P' against manufacturer documentation to confirm packaging details, as suffixes often denote reel or tape specifications rather than electrical changes. Ensure the 6A current rating aligns with your thermal management requirements. Cross-reference the 70 Ohm impedance at 100 MHz with your target frequency range to confirm effective attenuation performance.

Chip Ferrite Bead Selection Notes

Select this component when a single-line ferrite solution is required for power rails carrying up to 6 Amperes. The 1812 package offers a balance between current capacity and board space. Verify that the 30 mΩ DC resistance meets your voltage drop constraints. Consider the 70 Ohm impedance value relative to the noise frequencies present in your specific application environment.

Chip Ferrite Bead Part Context

This part belongs to Central Technologies' CTCB series of multilayer ferrite chip beads. These components are designed for electromagnetic interference suppression in compact electronic devices. The 1812 footprint is common in consumer electronics and industrial equipment where moderate current levels require efficient noise filtering without excessive board area consumption.
