B-01-A

Overview

The KEMET B-01-A is a shielded ferrite bead designed for DC line filtering applications. It features an axial termination type and operates within a temperature range of -20°C to +70°C. The component has a maximum DC current rating of 5A and provides an impedance of 2 Ohms at a test frequency of 1 MHz. Physical dimensions include a length of 67 mm and a diameter of 3.4 mm. The product is RoHS compliant and belongs to the Bead L series.

Feature Summary

• Shielded construction to contain magnetic fields
• Axial lead configuration for through-hole mounting
• High current handling capability up to 5A
• Low impedance value for minimal signal loss

Applications

• DC power line noise suppression
• Signal line filtering in electronic circuits
• EMI reduction in high-current applications

Procurement Notes

Verify the specific package designation, as distributor listings may indicate bulk packaging while other variants use different formats. Confirm the exact impedance tolerance and current derating curves against the official datasheet before integration. Ensure the axial lead style matches the PCB layout requirements. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a low-impedance, high-current ferrite bead is required for axial mounting. The 2 Ohm impedance at 1 MHz makes it suitable for suppressing higher frequency noise on DC lines without significant voltage drop. Consider the physical length of 67 mm for board space constraints. Compare with radial variants if space efficiency is prioritized over lead flexibility.

Part Context

This component belongs to KEMET's Bead L series of ferrite beads. These parts are passive electromagnetic components used for noise suppression. The B-01-A specifically utilizes an axial lead design, distinguishing it from surface-mount or radial options within the broader ferrite bead category. It is manufactured by KEMET, a global provider of passive electronic components.

Replacement Considerations

The B-01-A2 is listed as a related variant with similar electrical characteristics but potentially different mechanical configurations such as radial bending. Verify compatibility regarding lead style and physical dimensions before substitution.
