443164251

Overview

The Fair-Rite 443164251 is a split-core ferrite assembly designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43, providing an impedance of 210 ohms at 100 MHz and 138 ohms at 25 MHz. The component features a round cable aperture diameter of 6.3 mm (0.248 inches). Physical dimensions include a length of 32.2 mm (1.268 inches), width of 17.9 mm (0.705 inches), and height of 9.2 mm (0.362 inches). It is classified as a Round Cable Snap-It assembly.

Feature Summary

• Split-core design allows installation on existing cables without disconnection
• Material 43 composition provides high impedance in the frequency range of 1 to 100 MHz
• Snap-fit mechanism secures the core around the conductor

Applications

• Electromagnetic interference suppression on cables
• Common mode noise reduction in electronic assemblies
• Signal integrity enhancement for data lines

Procurement Notes

Verify that the target cable diameter does not exceed the 6.3 mm internal aperture to ensure proper fit. Confirm that the application environment remains within the operational temperature limits specified in the official datasheet. Check for RoHS compliance status if required by specific regulatory frameworks. Ensure the split-core latch mechanism engages securely during installation.

Selection Notes

Select this part when post-production cable modification is necessary. Material 43 is optimal for suppressing noise in the 1–100 MHz range. Compare impedance requirements against other materials if the dominant noise frequency differs significantly from the 100 MHz specification. Ensure the physical clearance accommodates the 32.2 mm length and 17.9 mm width.

Part Context

This component belongs to the Fair-Rite Round Cable Snap-It product line. These assemblies are engineered for rapid deployment on pre-existing wiring harnesses. The use of Material 43 distinguishes it from cores utilizing Material 31 or 61, which offer different permeability and loss characteristics across varying frequency spectrums.

Replacement Considerations

Fair-Rite 0443164251 is the standard manufacturer designation. Verify compatibility with generic split-core ferrites only if the aperture, material composition, and impedance curve match the original specifications exactly.
