5943001701

Overview

The Fair-Rite Products Corp. 5943001701 is a solid ferrite toroid core manufactured from Material 43, designed for inductive component applications. It features an outside diameter of 9.5 mm (0.375 inches) and an overall length of 31.75 mm (1.25 inches). The component operates within a temperature range of -55°C to +125°C and is RoHS compliant. This specific geometry is classified as a cable ferrite suitable for suppressing electromagnetic interference on wires.

Feature Summary

• Constructed from Material 43 nickel-zinc ferrite composition optimized for high-frequency noise suppression.
• Solid cylindrical design with a central aperture sized for direct wire passage without splitting.
• Capable of effective common-mode choke performance when cables are threaded through the center.

Applications

• Suppression of electromagnetic interference on signal and power cables.
• Construction of common-mode chokes for data transmission lines.
• Filtering high-frequency noise in electronic assembly wiring.

Procurement Notes

Verify that the required impedance characteristics align with Material 43 specifications at the target frequency. Confirm that the cable diameter fits within the internal dimensions of the 9.5 mm outer diameter core. Ensure compliance with RoHS3 standards if required by the final product regulations. Check for any specific packaging quantity requirements from the distributor.

Selection Notes

Select this part when a solid, non-split ferrite solution is preferred over split-core designs for permanent installations. Material 43 provides high permeability suitable for frequencies typically between 10 MHz and several hundred MHz. Consider the physical size constraints of the application to ensure the 31.75 mm length fits within the available space along the cable run.

Part Context

This component belongs to the Fair-Rite 59 series of cable ferrites. It utilizes the standard Material 43 formulation, which is widely used for general-purpose EMI suppression. The solid toroid shape distinguishes it from multi-aperture or split-core variants found in other Fair-Rite series.

Replacement Considerations

Direct substitutes include other manufacturers' Material 43 solid toroids with matching 9.5 mm OD and similar length. Equivalent Fair-Rite parts may exist in different series with identical material properties but varying geometries. Verify dimensional compatibility before substitution.
