431184751

Overview

Fair-Rite Products Corp. part number 431184751 is a snap-on ferrite core designed for electromagnetic interference suppression in cable assemblies. The component features a hinged design for easy installation around existing wires without disconnection. It utilizes Fair-Rite material 43, which provides high permeability suitable for suppressing noise in the frequency range of approximately 10 MHz to several hundred MHz. The core has an inner diameter of 0.750 inches (19.05 mm) width by 0.360 inches (9.14 mm) height and an outer dimension of 1.710 inches (43.43 mm) width by 1.130 inches (28.70 mm) height. At 100 MHz, it exhibits an impedance of 203 ohms. The device is rated for operation within a temperature range of -55°C to +125°C and complies with RoHS 3 standards.

Feature Summary

• Snap-on hinged design allows for rapid installation on cables without breaking the circuit loop
• Material 43 composition offers high magnetic permeability for effective broadband noise attenuation
• Solid construction ensures durability and consistent performance under mechanical stress

Applications

• Electromagnetic interference suppression for data communication cables
• Noise filtering on power supply lines in electronic equipment
• Signal integrity enhancement for peripheral device connections

Procurement Notes

Verify the specific material grade and impedance specifications against your application requirements before ordering. Confirm that the inner dimensions accommodate the target cable bundle diameter with sufficient clearance. Check for RoHS 3 compliance documentation if required by your manufacturing standards. Ensure the supplier provides genuine Fair-Rite products to guarantee material properties and dimensional accuracy.

Selection Notes

Select this component when a non-invasive solution for adding ferrite suppression to existing cable assemblies is required. Material 43 is appropriate for applications where noise frequencies are primarily above 10 MHz. Consider the physical size constraints of the assembly to ensure the snap-on core fits within the available space. Evaluate the impedance curve at your specific operating frequency to confirm adequate attenuation levels.

Part Context

This part belongs to Fair-Rite's Snap-It series of cable ferrites, which are engineered for convenience and ease of use in field installations or final assembly stages. Unlike split cores that require tools or solid cores that need wire threading, the hinged mechanism simplifies integration into finished wiring harnesses. The series is widely used in industrial, commercial, and consumer electronics for meeting regulatory emissions standards.

Replacement Considerations

Direct replacements must match the inner dimensions (0.750" x 0.360") and utilize Material 43 to maintain equivalent impedance characteristics. Verify that any substitute snap-on core has a similar outer profile to fit within enclosure constraints. Cross-reference impedance values at 100 MHz to ensure comparable noise suppression performance.
