FCB-0603-400P

Chip Ferrite Bead Overview

The FCB-0603-400P is a shielded ferrite bead from the Signal Transformer brand, designed for surface-mount applications in the 0603 (1608 metric) package. It provides an impedance of 40 Ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 3 A and features a maximum DC resistance of 35 mOhms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Shielded construction minimizes electromagnetic interference coupling between adjacent circuits.
• High current handling capability suitable for power line filtering applications.
• Compact surface-mount footprint enables dense PCB layout integration.

Chip Ferrite Bead Applications

• Power line noise suppression in portable electronics
• EMI filtering in high-density circuit boards
• Signal integrity enhancement in RF power stages

Chip Ferrite Bead Procurement Notes

Verify the manufacturer part number against official Signal Transformer documentation to ensure authenticity. Confirm RoHS compliance status and specific lot traceability requirements prior to ordering. Check for any recent product change notices regarding material composition or manufacturing location changes.

Chip Ferrite Bead Selection Notes

Select this component when a compact, shielded ferrite bead is required for power lines carrying up to 3 A. Ensure the 40 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Verify that the 0603 package dimensions fit the available board space and soldering profile constraints.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the FCB series of surface-mount components manufactured by Signal Transformer. It is engineered for general-purpose EMI suppression in consumer and industrial electronics where space is limited and shielding is necessary to prevent crosstalk.

Chip Ferrite Bead Replacement Considerations

Consult Signal Transformer's official cross-reference guides for verified substitutes. Ensure replacement parts match the 40 Ohm impedance, 3 A current rating, and 0603 package dimensions. Verify compatibility with existing assembly processes and regulatory certifications.
