B-20F-46

Overview

The KEMET B-20F-46 is a cylindrical ferrite bead core designed for round cables. Constructed from Manganese Zinc (MnZn) material, it features an inner diameter of 1.5mm and an outer diameter of 4.6mm. The component has a length of 4.3mm and utilizes a free-hanging installation method. It is intended for high-voltage or current applications requiring electromagnetic interference suppression.

Feature Summary

• Cylindrical MnZn ferrite core design
• Free-hanging suspension style
• Optimized for round cable integration

Applications

• Round cable EMI suppression
• High voltage circuit filtering
• Current carrying line noise reduction

Procurement Notes

Verify the specific MnZn composition and dimensional tolerances against the official KEMET datasheet to ensure compatibility with target cable diameters. Confirm that the free-hanging form factor meets mechanical constraints within the assembly environment before finalizing procurement orders.

Selection Notes

Select this component when managing round cables in high-voltage environments. The MnZn material offers effective attenuation characteristics. Ensure the 1.5mm inner diameter accommodates the specific cable gauge used in the application without excessive clearance or tight fit issues.

Part Context

This part belongs to the KEMET B-20 series of bead cores. The series provides various Manganese Zinc and Nickel Zinc options tailored for different frequency ranges and cable sizes. The B-20F-46 specifically addresses needs for compact, suspended ferrite solutions on standard round wiring.

Replacement Considerations

Check for other B-20 series variants with matching 1.5mm inner diameter and similar MnZn properties. Verify physical dimensions and material composition match exactly to maintain performance equivalence.
