444177081

Overview

Fair-Rite 0444177081 is a round cable Snap-It ferrite clamp core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 44, providing an impedance of 330 ohms at 250 MHz and 182 ohms at 100 MHz. The component features a split design with a 25.65 mm inner diameter to accommodate cables ranging from 2.5 mm to 25.4 mm in diameter. Physical dimensions are 56.4 mm in width, 42.95 mm in length, and 27.45 mm in height. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Snap-It split design allows installation on existing cables without disconnection
• Material 44 composition optimized for high-frequency noise suppression
• Controlled impedance characteristics for consistent EMI performance

Applications

• Suppression of common mode noise on round cables
• Filtering bundled wire assemblies
• Electromagnetic interference mitigation in electronic systems

Procurement Notes

Verify the exact part number as the provided model lacks the leading zero found in official documentation (0444177081). Confirm material specification matches requirements, as this unit uses Material 44. Check RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory status can vary by production batch and region.

Selection Notes

Select this component when dealing with round cables or bundles between 2.5 mm and 25.4 mm in diameter. Material 44 is suitable for applications requiring significant attenuation in the VHF/UHF range. Ensure the physical aperture size accommodates the specific cable bundle diameter to maintain effective magnetic coupling and impedance performance.

Part Context

This component belongs to the Fair-Rite Round Cable Snap-It series, which provides convenient clamping solutions for ferrite cores. These assemblies are distinct from solid toroids or split rings that require tool assistance. The series is engineered for rapid deployment on pre-existing wiring harnesses in various electronic environments.

Replacement Considerations

Direct substitutes include other Fair-Rite Material 44 snap-it cores with similar inner diameters, such as 0444167281 for smaller cables. Cross-manufacturer equivalents must match the Material 44 permeability and physical dimensions to ensure comparable impedance curves.
