CT0443164251F

Overview

The CT0443164251F is a hinged, snap-on free-hanging ferrite core designed for EMI suppression on round cables. It features an inner diameter of 0.256 inches (6.50mm) and outer dimensions of 0.807 inches wide by 0.787 inches high (20.50mm x 20.00mm), with a length of 0.787 inches (20.00mm). The component provides an impedance of 200 Ohms at 100MHz, offering common-mode filtering capabilities for multi-strand cables without requiring permanent installation.

Feature Summary

• Hinged snap-on design allows for easy installation and removal around existing cables
• Provides effective common-mode filtering for multi-strand cable assemblies
• Free-hanging configuration enables flexible mounting in various spatial constraints

Applications

• EMI suppression for multi-strand cables
• Common-mode noise filtering in electronic interconnects
• Round cable protection against electromagnetic interference

Procurement Notes

Verify the specific impedance requirements against application frequency ranges to ensure adequate noise suppression. Confirm that the cable diameter falls within the 0.256-inch inner diameter specification to guarantee a secure fit. Check for any environmental ratings if the component will be exposed to extreme temperatures or harsh conditions, as standard ferrite cores may have limited thermal tolerance.

Selection Notes

Select this component when non-invasive cable treatment is required for EMI reduction. The snap-on mechanism is ideal for retrofits or prototyping where soldering or clamping is impractical. Ensure the target cable is round and fits within the specified bore size. Consider the 200 Ohm impedance at 100MHz as the primary performance metric for noise attenuation needs.

Part Context

This ferrite core belongs to Central Technologies' line of Round Cable Snap-its, which are engineered for convenient EMI management. Unlike split-core designs that require precise alignment, the hinged construction simplifies handling. It serves as a passive solution for mitigating conducted emissions in systems utilizing multi-strand wiring harnesses.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility based on identical impedance characteristics, physical dimensions, and snap-on mechanical design before considering alternative vendors.
