The Ferroxcube BDS3/3/8.9-4S2-Z is a surface-mount ferrite bead designed for EMI suppression in high-frequency circuits. It features a compact SMD package with dimensions of 2.8mm by 6.4mm. The component exhibits an impedance of 100Ω at 100MHz and 65Ω at 25MHz, providing effective noise attenuation. It supports a current rating of 10A with a DC resistance below 0.001Ω. This part is RoHS compliant and suitable for applications requiring reliable signal integrity in dense PCB layouts.
Verify the specific suffix 'Z' indicates tape-and-reel packaging when ordering. Confirm the manufacturer's datasheet for exact impedance tolerances and thermal derating curves. Ensure the selected variant matches the required current handling capabilities for the specific application environment.
Select this component based on its 100Ω impedance at 100MHz for targeted frequency noise reduction. Evaluate the 10A current rating against peak load requirements to prevent saturation. Consider the small footprint for high-density board layouts where space is limited.
This ferrite bead belongs to Ferroxcube's passive EMI/RFI suppression product range. It utilizes specialized ferrite materials optimized for broadband noise absorption. The series is engineered for consistency in mass production environments.
Check for equivalent SMD ferrite beads from other manufacturers offering similar 100Ω @ 100MHz impedance and 10A current ratings. Verify physical footprint compatibility before substitution.
The impedance at 25MHz is specified as 65Ω.
Yes, it is rated for a current of 10A with very low DC resistance.
