B-20L-48B-L

Overview

The KEMET B-20L-48B-L is a nickel-zinc (Ni-Zn) ferrite cable core designed for electromagnetic interference suppression. It features a round, solid construction with an internal 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 optimized for noise suppression applications at frequencies up to 300 MHz.

Feature Summary

• Constructed from nickel-zinc ferrite material for effective high-frequency noise attenuation
• Solid round toroidal shape engineered specifically for circular cables
• Robust physical structure ensures durability in general electronic environments

Applications

• Electromagnetic interference suppression in general electronics
• Noise filtering for circular cables
• Low and high frequency application mitigation

Procurement Notes

Verify the specific manufacturer part number against official KEMET documentation to ensure compatibility with design requirements. Confirm that the nickel-zinc composition aligns with intended frequency performance needs. Check for any RoHS compliance details in the latest datasheet version before finalizing procurement decisions.

Selection Notes

Select this component when dealing with circular cables requiring EMI suppression in the 300 MHz range. Ensure the cable diameter fits within the 2.4 mm inner bore. Consider the operating temperature limits of -25 °C to +85 °C for environmental suitability. Verify that the Ni-Zn material properties match the specific impedance characteristics required by the circuit design.

Part Context

This component belongs to the KEMET B-20 series of ferrite cable cores. It serves as a passive EMI suppression device, distinct from active components or other capacitor types offered by the manufacturer. The product is categorized under noise suppression solutions for signal and power lines.

Replacement Considerations

Cross-reference with equivalent Ni-Zn ferrite sleeves having identical 2.4 mm ID and 4.8 mm OD dimensions. Verify magnetic permeability and frequency response curves to ensure functional equivalence in noise suppression performance.
