2944666671

Overview

Fair-Rite 2944666671 is a wound bead ferrite component from the 29 series, designed for electromagnetic interference suppression. It utilizes Material 44 and features an axial termination style with a single turn of tinned copper wire wound around the core. The impedance is specified at 1.02 kOhms when tested at a frequency of 100 MHz. The physical dimensions are 10 mm in length and 6 mm in diameter. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Constructs noise suppression using Material 44 ferrite composition
• Features axial leads for through-hole mounting applications
• Incorporates a single-turn tinned copper wire winding configuration

Applications

• Electromagnetic interference suppression in electronic circuits
• Common mode noise filtering on signal lines
• High-frequency harmonic attenuation in power supplies

Procurement Notes

Verify the specific material grade and impedance tolerance against the official Fair-Rite datasheet before integration. Confirm that the axial lead spacing and physical dimensions match the target PCB footprint requirements. Ensure the operating temperature range aligns with the environmental conditions of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar wound bead variants.

Selection Notes

Select this component when high impedance at 100 MHz is required for noise reduction. The axial form factor suits manual or wave soldering processes. Material 44 provides effective performance for frequencies above 10 MHz. Evaluate the current carrying capacity of the single-turn wire against the circuit load. Consider the physical size constraints relative to available board space.

Part Context

This component belongs to the Fair-Rite 29 series of wound beads. The series includes various hole counts and materials. Material 44 is a nickel-zinc formulation optimized for higher frequency applications. The wound bead design allows for easy installation on existing wires or traces without complex surface mount equipment.

Replacement Considerations

Check Fair-Rite documentation for direct substitutes within the 29 series. Verify equivalent impedance values at 100 MHz for any alternative parts. Ensure physical dimensions and lead types remain compatible with the existing assembly process.
