2944777741

Overview

Fair-Rite 2944777741 is a wound ferrite bead utilizing 44-grade NiZn material. It provides high EMI suppression performance across the 30 to 500 MHz frequency range. The component features a cylindrical design with an impedance of 500 ohms at 100 MHz. It supports 24 AWG wire and has dimensions of 38.0±3.0 mm length.

Feature Summary

• High suppression performance from 30 to 500 MHz
• Utilizes 44-grade NiZn ferrite material
• Cylindrical wound bead design

Applications

• EMI suppression in electronic circuits
• Filtering noise on 24 AWG wires
• High-frequency signal integrity management

Procurement Notes

Verify the specific impedance value and physical dimensions against the official Fair-Rite datasheet before integration. Confirm that the 44-grade material properties align with the target frequency requirements for the intended application. Ensure compatibility with the required wire gauge and mounting constraints.

Selection Notes

Select this component when high attenuation is required between 30 and 500 MHz. The 44-grade material offers a balance of permeability and resistivity suitable for broadband noise suppression. Consider the cylindrical form factor and 24 AWG compatibility during mechanical design.

Part Context

This part belongs to the Fair-Rite 29 series of wound beads. It is designed for applications requiring robust EMI filtering without the need for complex circuitry. The 44 material grade is distinct for its high initial permeability and loss characteristics in the VHF/UHF spectrum.

Replacement Considerations

Check Fair-Rite catalog for other 44-grade wound beads with similar impedance and dimensional tolerances. Verify if alternative materials like 31 or 61 offer better performance for specific frequency bands outside the 30-500 MHz range.
