Overview
The Ferroxcube BD8/3/4-4S2 is a cylindrical ferrite bead designed for cable shielding and electromagnetic interference suppression. It utilizes 4S2 material composition to provide high impedance characteristics at radio frequencies. The component features a single-hole design with an internal diameter of 4.75 mm, allowing it to accommodate cables of corresponding thicknesses. Key electrical specifications include an impedance of 43 Ohms measured at 100 MHz. The physical dimensions consist of an outer diameter of 8 mm and a length of 3 mm. This tubular core is supplied in bulk packaging and is compliant with RoHS3 standards.
Feature Summary
- Provides effective electromagnetic interference suppression through high impedance characteristics at radio frequencies
- Features a cylindrical tubular geometry suitable for sliding over cables without additional mounting hardware
- Constructed from 4S2 ferrite material optimized for broadband noise absorption
Applications
- Cable shielding for data lines and power cords
- Electromagnetic interference suppression in electronic assemblies
- Common mode noise reduction on signal cables
Procurement Notes
Verify the specific impedance tolerance and material batch consistency against the manufacturer's datasheet before integration. Confirm that the internal diameter accommodates the target cable bundle diameter with appropriate clearance. Ensure compliance with project-specific environmental regulations such as RoHS3 requirements. Check for any mechanical constraints regarding the external diameter and overall length within the assembly housing.
Selection Notes
Select this component when a simple, low-profile solution is required for suppressing high-frequency noise on individual cables. The 4S2 material offers a balance of permeability and resistivity suitable for general-purpose EMI applications. Consider the thermal environment and current carrying capacity of the cable rather than the bead itself, as the ferrite acts primarily as a magnetic load. Evaluate the frequency spectrum of the noise source to ensure the 100 MHz impedance peak aligns with the interference profile.
Part Context
This part belongs to the Ferroxcube range of tubular ferrite beads and cores. These components are distinct from chip beads or clip-on types, offering a universal fit for various cable diameters. The BD series designation indicates specific dimensional tolerances and shape characteristics defined by the manufacturer. Ferrite beads are passive components that do not require electrical connections, relying solely on magnetic coupling with the conductor passing through them.
Replacement Considerations
Substitute parts must match the 4.75 mm inner diameter, 8 mm outer diameter, and 3 mm length. Verify that alternative materials provide comparable impedance values at 100 MHz. Ensure the replacement component meets the same RoHS3 compliance status.
