B-3

Overview

The KEMET B-3 is a signal line ferrite bead designed for axial and radial bend configurations. It features a compact 0.51mm bead winding structure optimized for noise suppression in high-current applications. The component supports a nominal current rating of 3.5A, ensuring stable performance under significant load conditions. This ferrite bead serves as an effective electromagnetic interference (EMI) filter for protecting sensitive electronic circuits from high-frequency noise.

Feature Summary

• Compact 0.51mm bead winding design for space-constrained layouts
• Supports 3.5A nominal current for robust signal line protection
• Available in both axial and radial bend lead forms for flexible mounting

Applications

• Signal line noise suppression
• Electromagnetic interference filtering
• High-current circuit protection

Procurement Notes

Verify the specific impedance characteristics and frequency response curves against your application requirements, as ferrite beads are highly frequency-dependent. Confirm that the axial or radial bend lead style matches your PCB footprint constraints. Ensure the 3.5A current rating exceeds the maximum operating current of your signal line to prevent saturation or thermal issues during operation.

Selection Notes

Select this component when a low-profile ferrite solution is required for signal lines carrying up to 3.5A. The choice between axial and radial bend leads should be driven by mechanical assembly preferences and board space availability. Consider the specific frequency range of the noise you intend to suppress, as ferrite materials have distinct permeability characteristics across different bands.

Part Context
