2944666634

Overview

Fair-Rite 2944666634 is a radial wound ferrite bead from the Series 29 product line. It utilizes Material 44 for high-frequency noise suppression. The component exhibits an impedance of 690 ohms at a test frequency of 100 MHz. Physical dimensions are 10 mm in length and 6 mm in diameter. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Radial wound construction for through-hole mounting
• Material 44 composition for broadband attenuation
• High impedance characteristic at 100 MHz

Applications

• Electromagnetic interference filtering on single conductors
• Common mode noise suppression in power lines
• Signal integrity enhancement in high-speed digital circuits

Procurement Notes

Verify the specific impedance value against current manufacturer datasheets, as distributor listings may vary between 600 and 690 ohms. Confirm package availability options such as cut tape or reel formats directly with authorized suppliers. Ensure Material 44 specification matches design requirements for target frequency bands.

Selection Notes

Select this component when radial mounting is required for Material 44 ferrite applications. Compare impedance performance against Series 27 surface mount alternatives if board space is constrained. Validate thermal stability requirements against the specified operating temperature range of -55°C to +125°C.

Part Context

This part belongs to Fair-Rite's Series 29 family of wound ferrite beads. These components are designed for general-purpose EMI suppression. The numbering system indicates the material type and physical configuration. Series 29 parts typically offer robust mechanical strength compared to chip-style beads.

Replacement Considerations

Fair-Rite 2944666651 offers similar radial wound construction with Material 44 but specifies 600 ohms impedance at 100 MHz. Verify impedance tolerance compatibility before substitution.
