B-20L-48B

Overview

The KEMET B-20L-48B is a solid nickel-zinc (Ni-Zn) ferrite cable core designed for electromagnetic interference (EMI) suppression. It features a round shape with an inner diameter of 2.4 mm, an outer diameter of 4.8 mm, and an external length of 4.8 mm. The component operates within a temperature range of -25°C to +85°C and is rated for frequencies up to 300 MHz. It supports a maximum voltage rating of 150 V and meets AEC-Q200 qualification standards.

Feature Summary

• Solid Ni-Zn ferrite construction for effective EMI suppression
• Round sleeve design suitable for free-hanging installation
• AEC-Q200 qualified for automotive reliability

Applications

• General electronic equipment EMI filtering
• Round cable noise suppression
• Automotive wiring harness protection

Procurement Notes

Verify the specific suffix (e.g., -L, -A) against the datasheet to confirm exact dimensional tolerances and material batch consistency. Ensure the selected variant matches the required voltage rating and frequency response for the target application environment.

Selection Notes

Select this component when a compact, solid ferrite ring is needed for cables with a 2.4 mm diameter. Consider the Ni-Zn material properties for high-frequency attenuation above 300 MHz and verify thermal stability requirements against the -25°C to +85°C operating range.

Part Context

This part belongs to the KEMET B-20L series of solid ferrite cores. These components are engineered for straightforward installation on existing cables without requiring disconnection, providing a passive solution for radiated and conducted noise reduction in sensitive electronic systems.

Replacement Considerations

Cross-reference dimensions strictly. Variants like B-20L-48B-L or B-20L-48B-A may share core specs but differ in packaging or minor tolerance specifications. Confirm AEC-Q200 compliance if automotive use is intended.
