475181651

Overview

Fair-Rite Products Corp. part number 475181651 is an openable split-core ferrite clamp designed for electromagnetic interference (EMI) suppression applications. The component features a circular aperture with a diameter of 4.09 mm, accommodating cables within this size constraint. It operates effectively at frequencies starting from 200 kHz up to 30 MHz. The physical dimensions are specified as 23 mm in width, 13 mm in height, and 12.1 mm in depth. This design allows for installation on existing cable assemblies without disconnecting the conductors.

Feature Summary

• Openable split-core construction enables retrofitting onto installed cables
• Circular aperture geometry optimized for round wire harnesses
• Engineered for broadband EMI noise attenuation

Applications

• Suppression of electromagnetic interference on data cables
• Noise reduction on power supply wiring
• Signal integrity improvement in electronic equipment cabling

Procurement Notes

Verify that the target cable diameter does not exceed the 4.09 mm internal aperture specification to ensure proper fit. Confirm that the operating frequency range of the application aligns with the component's effective performance window between 200 kHz and 30 MHz. Check for RoHS compliance requirements if the end product demands restricted substance limitations. Ensure the mechanical clamping force is sufficient for the intended environment.

Selection Notes

Select this model when post-assembly installation is required, as opposed to solid cores used during manufacturing. Compare impedance characteristics against other Fair-Rite materials if specific frequency targeting is needed beyond the general 200 kHz to 30 MHz range. Consider the physical footprint constraints of the enclosure where the clamp will be mounted. Evaluate whether the split-core mechanism provides adequate retention compared to adhesive or snap-fit alternatives.

Part Context

This component belongs to the Fair-Rite openable ferrite clamp series, distinct from solid cylindrical cores like the 2643 series. It utilizes specific ferrite formulations tailored for low-frequency to mid-range noise suppression. The split design differentiates it from traditional toroidal or bead cores that require cable threading during production.
