461164181

Overview

Fair-Rite 461164181 is a split core ferrite assembly designed for cable EMI suppression. It utilizes Fair-Rite Material 61, providing high impedance in the VHF/UHF range. The unit features a snap-on design with an inner diameter of 0.514 inches (13.06 mm) and outer dimensions of 1.220 x 0.600 inches (30.99 x 15.24 mm). It achieves an impedance of 205 Ohms at 100 MHz and 365 Ohms at 1 GHz.

Feature Summary

• Snap-on split core design allows installation on existing cables without disconnection
• Material 61 composition provides effective noise attenuation in VHF and UHF frequency bands
• Solid construction ensures stable impedance characteristics for signal integrity

Applications

• Suppression of electromagnetic interference on round cables and wire bundles
• Filtering noise from motor drives and power supplies
• Common-mode choke applications in electronic equipment cabling

Procurement Notes

Verify that the specific order code matches the required impedance specifications for your frequency range. Confirm compatibility with the cable diameter to ensure proper fit within the 13.06 mm inner diameter. Check RoHS compliance status if required by project regulations. Ensure the split core mechanism functions correctly upon closure.

Selection Notes

Select this component when high-frequency noise suppression is required for cables that cannot be disconnected during installation. The Material 61 formulation is optimal for frequencies above 100 MHz. Compare physical dimensions against available space constraints. Consider the snap-on convenience versus solid cores for maintenance-heavy environments.

Part Context

This part belongs to the Round Cable Snap-It series, which are controlled for impedance values. These assemblies are engineered to accommodate round cables or bundled wires with diameters ranging from 2.5 mm to 25.4 mm. They serve as passive filters to mitigate conducted emissions in sensitive electronic systems.
