CTCB1812F-125S

Chip Ferrite Bead Overview

The CTCB1812F-125S is a multilayer ferrite chip bead manufactured by Central Technologies. It features an 1812 (4532 Metric) surface-mount package and provides 125 Ohms of impedance at 100 MHz. The component supports a current rating of 4A with a maximum DC resistance of 30mOhm. Designed for noise suppression, it operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Multilayer ferrite construction for effective high-frequency noise attenuation
• Surface-mount design compatible with automated assembly processes
• High current handling capability suitable for power line filtering

Chip Ferrite Bead Applications

• DC power supply input/output filtering
• Noise suppression on data lines
• EMI reduction in consumer electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'S' against the manufacturer's official documentation to confirm packaging configuration, as suffixes often denote reel or tape quantities rather than electrical changes. Ensure the requested quantity matches the standard shipping unit defined in the latest datasheet revision. Cross-reference the date code to confirm freshness if long-term storage stability is required for your application timeline.

Chip Ferrite Bead Selection Notes

Select this component when a 1812 footprint is available and 4A continuous current capacity is necessary. The 125 Ohm impedance at 100 MHz targets common noise frequencies in digital circuits. Verify that the 30mOhm DC resistance meets the voltage drop requirements of your specific circuit design before finalizing the selection.

Chip Ferrite Bead Part Context

Central Technologies produces this ferrite bead as part of their general-purpose magnetic component lineup. The 1812 case size offers a balance between physical footprint and thermal/current performance compared to smaller packages like 0603 or 0805.
