444164281

Overview

The Fair-Rite Products Corp. part number 444164281 is a round cable Snap-It™ assembly constructed from 44 material ferrite. It functions as a split-core ferrite bead designed for electromagnetic interference suppression on round cables or bundled wires with diameters ranging from 2.5mm to 25.4mm. The component has an inner diameter of approximately 6.3mm to 6.6mm and provides an impedance of 260 ohms at 100MHz. It is controlled for impedance values only, with minimum specifications defined at marked frequencies.

Feature Summary

• Snap-It design allows easy installation around existing round cables without disconnection
• Utilizes 44 material composition for high-frequency noise attenuation
• Accommodates a wide range of cable diameters from 2.5mm to 25.4mm

Applications

• Electromagnetic interference suppression in power supplies
• Noise filtering for motor drive cables
• Common-mode choke applications for bundled wires

Procurement Notes

Verify the specific impedance tolerance requirements against the manufacturer's datasheet, as this component is controlled for minimum impedance values at specified frequencies. Confirm that the target cable diameter falls within the 2.5mm to 25.4mm operational range. Ensure the application environment is compatible with the ferrite material properties. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when retrofitting ferrite suppression onto existing cabling assemblies where traditional through-hole cores are impractical. The 44 material is suitable for higher frequency noise reduction compared to standard 31 material cores. Consider the physical clearance required for the snap-fit mechanism and the maximum cable bundle diameter to ensure proper fit and effective magnetic coupling.

Part Context

This part belongs to Fair-Rite's Snap-It family of split-core ferrites, which are engineered for convenient field installation. Unlike solid toroids, these assemblies feature a split design that snaps together around conductors. The 44 material variant is distinct from other offerings like 61 or 31 materials, offering specific permeability characteristics tailored for broadband noise suppression in electronic systems.

Replacement Considerations

Direct substitutes include other Fair-Rite Snap-It cores with similar inner diameters and 44 material composition, such as part numbers ending in 44-material variants. Verify that alternative split-core designs maintain comparable impedance curves at 100MHz to ensure equivalent noise attenuation performance in the circuit.
