BDS3/3/4.6-4S2

Overview

The Ferroxcube BDS3/3/4.6-4S2 is a surface-mount ferrite bead designed for electromagnetic interference (EMI) suppression in high-current applications. It features a compact chip body with dimensions of 4.6 mm length, 3.1 mm width, and 3.0 mm height. The component provides an impedance of 50 Ohms at 100 MHz while supporting a maximum current rating of 10 A. Its low DC resistance, specified as less than 1 mOhm, ensures minimal signal loss and power dissipation in the circuit path.

Feature Summary

• Provides effective EMI noise attenuation across high-frequency ranges
• Capable of handling high continuous current loads without saturation
• Utilizes J-lead termination for reliable surface-mount assembly

Applications

• Power supply output filtering
• High-speed data line noise suppression
• DC-DC converter input/output stages

Procurement Notes

Verify the specific suffix designation during procurement to ensure compatibility with required impedance characteristics and current ratings. Confirm that the selected variant matches the intended surface-mount footprint and termination style for proper integration into the target PCB layout.

Selection Notes

Select this component when designing circuits requiring significant current handling alongside broadband noise reduction. Ensure the operating temperature range aligns with system requirements and verify that the low DC resistance meets efficiency targets for power-sensitive applications.
