2944666651

Overview

Fair-Rite 2944666651 is a wound ferrite bead utilizing Material 44. It provides an impedance of 600 Ohms at a test frequency of 100 MHz. The component features radial termination and operates within a temperature range of -55°C to +125°C. Physical dimensions are 10 mm in length and 6 mm in diameter, with a unit weight of 1.300 g.

Feature Summary

• Wound bead construction using high-permeability Material 44 for effective noise suppression
• Radial leaded configuration designed for through-hole circuit board mounting

Applications

• Electromagnetic interference (EMI) filtering on signal lines
• Common mode noise reduction in electronic assemblies
• High-frequency circuit protection components

Procurement Notes

Verify the specific impedance value of 600 Ohms at 100 MHz against design requirements. Confirm that the radial termination style matches the target PCB layout. Ensure the operating temperature range of -55°C to +125°C meets environmental specifications. Check RoHS compliance status via official manufacturer documentation before finalizing procurement.

Selection Notes

Select this component when a wound ferrite bead with radial leads is required for EMI suppression. Material 44 offers high permeability suitable for lower frequency noise attenuation compared to other materials. The 600 Ohm impedance at 100 MHz defines its filtering characteristics. Verify physical space constraints for the 10 mm length and 6 mm diameter footprint.

Part Context

This part belongs to Fair-Rite's 29 series of wound ferrite beads. It utilizes Material 44, which is optimized for applications requiring high initial permeability. The radial package distinguishes it from surface mount or axial variants within the same material family.

Replacement Considerations

The datasheet lists 2961666651 as a related variant within the same series. Verify if alternative winding configurations or packaging styles from the 29 series meet identical electrical and mechanical requirements.
