444164951

Overview

Fair-Rite Products Corp. part number 0444164951 is a Snap-It™ hinged ferrite core designed for cable electromagnetic interference suppression. It utilizes Material 44, providing an impedance of 245 ohms at 100 MHz. The component features a circular design with a hinged clamping mechanism for free-hanging installation. Internal dimensions include a 0.201-inch (5.11 mm) diameter bore. External measurements are 0.680 inches wide by 0.331 inches high (17.27 mm x 8.41 mm), with a total length of 1.420 inches (36.07 mm).

Feature Summary

• Hinged snap-clamp design allows for easy installation and removal around existing cables without disconnection.
• Material 44 composition provides specific high-frequency noise attenuation characteristics.
• Circular geometry accommodates round wire bundles effectively.

Applications

• Suppression of common-mode noise on power and signal cables in electronic equipment.
• EMI reduction in computer peripheral connections and data lines.
• Noise filtering in industrial control wiring harnesses.

Procurement Notes

Verify the complete manufacturer part number includes the leading zero (0444164951) to ensure correct identification. Confirm Material 44 specification matches application frequency requirements. Check RoHS3 compliance status if required by project regulations. Ensure cable diameter falls within the 5.11 mm internal bore limit for proper fit.

Selection Notes

Select this component when hinged access is necessary for cable management. Material 44 is suitable for frequencies above 100 MHz. Compare impedance values against other Fair-Rite materials like 31 or 43 if lower frequency performance is needed. Verify physical clearance for the 36.07 mm length and 17.27 mm width in the assembly layout.

Part Context

This part belongs to the Snap-It™ series of hinged ferrite cores from Fair-Rite. These assemblies are distinct from solid split cores due to their integrated hinge mechanism. They are categorized under cable ferrites for EMI suppression rather than transformer cores.

Replacement Considerations

Direct substitutes may include other Fair-Rite hinged cores with similar Material 44 properties and comparable internal diameters. Verify impedance curves match the original design requirements before substitution.
