B-20L-95B

Overview

The KEMET B-20L-95B is a solid suspension ferrite bead core designed for round cables. It belongs to the B-20 series and utilizes Nickel-Zinc (Ni-Zn) material. The component features a coated finish for environmental protection. Key dimensions include an inner diameter of 4.8 mm, an outer diameter of 9.7 mm, and a length of 4.2 mm. It serves as an EMI suppression device for high-frequency applications.

Feature Summary

• Solid suspension design for easy installation on round cables
• Nickel-Zinc material composition suitable for high-frequency noise suppression
• Coated surface finish for enhanced durability

Applications

• EMI suppression on round cables
• High-frequency noise reduction in electronic assemblies
• Cable protection in communication equipment

Procurement Notes

Verify the specific part number B-20L-95B against official KEMET documentation to confirm Ni-Zn material properties and dimensional tolerances. Ensure the coated variant matches project requirements. Cross-reference with authorized distributors to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when round cable geometry requires a snap-on or slide-on ferrite solution. The Ni-Zn formulation targets higher frequency ranges compared to Mn-Zn alternatives. Confirm that the 4.8 mm inner diameter accommodates the target cable bundle without excessive clearance.

Part Context

This component is part of the KEMET B-20 series of bead cores. The series offers various dimensions and materials to address different cable sizes and frequency spectra. The B-20L-95B specifically addresses mid-range cable diameters with a compact footprint.

Replacement Considerations

Check for direct substitutes within the B-20 series with matching inner diameter and material type. Verify equivalent impedance characteristics at the target operating frequency before substitution.
