FCB-0603-300A

Chip Ferrite Bead Overview

The FCB-0603-300A is a single-channel ferrite chip bead manufactured by Bel Signal Transformer, designed for surface-mount applications. It features a 0603 (1608 metric) package with dimensions of 1.6 mm in length, 0.8 mm in width, and 0.8 mm in height. The component provides an impedance of 30 Ohms at a test frequency of 100 MHz, with a tolerance of 25%. It supports a maximum DC current of 400 mA and has a maximum DC resistance of 100 mOhms. The device operates within a temperature range of -55°C to +125°C and is shielded.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies.
• Utilizes a compact 0603 surface-mount footprint for efficient PCB space utilization.
• Features shielded construction to contain magnetic fields and reduce external noise coupling.

Chip Ferrite Bead Applications

• High-speed data line filtering in portable electronic devices
• Power supply input/output noise suppression in consumer electronics
• Signal integrity enhancement in communication modules

Chip Ferrite Bead Procurement Notes

Verify the manufacturer part number against official Bel Signal Transformer documentation to ensure authenticity. Confirm that the 0603 package dimensions and electrical parameters match system requirements. Check RoHS compliance status via the manufacturer's datasheet or certification documents before integration into regulated products.

Chip Ferrite Bead Selection Notes

Select this component when a low-profile ferrite bead is required for EMI suppression in space-constrained designs. Ensure the operating current does not exceed 400 mA to prevent saturation. Verify that the 30 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Consider the -55°C to +125°C operating range for environmental suitability.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the general-purpose signal conditioning category from Bel Signal Transformer. It is distinct from power inductors like the SCRH8D43 series or ceramic chip inductors such as the FCBA1 series. The product focuses on broadband noise attenuation rather than energy storage or tuned circuit applications.

Chip Ferrite Bead Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing requires matching impedance, current rating, and package size with equivalent components from other manufacturers using official compatibility databases.
