BD8/1.5/4-4S2

Overview

The Ferroxcube BD8/1.5/4-4S2 is a cylindrical ferrite bead designed for electromagnetic interference suppression in electronic circuits. It utilizes the proprietary 4S2 soft ferrite material, which provides high permeability and low core losses across a wide frequency range. The component features a free-hanging installation type suitable for wire wrapping or through-hole mounting. Key physical dimensions include an outer diameter of 8 mm, an inner diameter of 1.5 mm, and a length of 4 mm. This configuration allows it to be placed directly on cables to attenuate common-mode noise.

Feature Summary

• Cylindrical geometry optimized for direct cable mounting
• High-frequency noise attenuation using specialized ferrite composition
• Free-hanging design facilitates easy integration into wiring harnesses

Applications

• Suppression of electromagnetic interference in digital signal lines
• Noise filtering for power supply input and output cables
• Common-mode noise reduction in communication interfaces

Procurement Notes

Verify that the ordered part number exactly matches BD8/1.5/4-4S2 to ensure the correct 4S2 material grade and dimensional specifications. Confirm RoHS3 compliance status if required by specific environmental regulations. Check datasheet parameters for impedance characteristics at target frequencies to validate suitability for the intended noise spectrum. Ensure packaging quantity aligns with production requirements as standard packs may vary.

Selection Notes

Select this component when space constraints require a compact cylindrical form factor for cable-mounted filtering. The 4S2 material offers a balance of permeability and loss characteristics suitable for general-purpose EMI suppression. Consider the 1.5 mm inner diameter to ensure compatibility with the target cable gauge. Evaluate the operating frequency range against the noise profile to confirm effective attenuation performance.
