2944666631

Overview

Fair-Rite 2944666631 is a wound ferrite bead utilizing Material 44. It features radial termination and provides an impedance of 690 Ohms at a test frequency of 100 MHz. The component operates within a temperature range of -55°C to +125°C. Physical dimensions are 10 mm in length and 6 mm in diameter. It is supplied in bulk packaging.

Feature Summary

• Wound construction using tinned copper wire on Material 44 core
• Radial lead termination for through-hole mounting
• High impedance performance at 100 MHz

Applications

• Electromagnetic interference suppression in electronic circuits
• Common mode noise filtering on signal lines
• Power line noise attenuation

Procurement Notes

Verify the specific impedance value required, as sources indicate both 690 Ohms and 1.2 kOhm for this part number. Confirm the winding configuration matches the design intent. Check RoHS compliance status directly with the manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when high impedance at 100 MHz is required for radial mounting applications. Material 44 offers specific permeability characteristics suitable for general EMI suppression. Ensure the physical size fits the available board space and that the current rating meets the circuit requirements.

Part Context

This part belongs to Fair-Rite's product class 29 series, which consists of beads wound with tinned copper wire. These components differ from solid cores or chip beads by offering higher inductance and impedance through the wire winding technique on the ferrite material.

Replacement Considerations

Check Fair-Rite catalog for other Material 44 wound beads with similar impedance values. Verify if alternative materials like Material 31 or 61 offer better performance for specific frequency ranges.
