5943000101

Overview

Fair-Rite Products Corp. part number 5943000101 is a solid ferrite toroid core manufactured from 43 material grade. The component features an inner diameter of 3.05 mm (0.120 inches), an outer diameter of 5.83 mm (0.230 inches), and a length of 1.65 mm (0.065 inches). It is designed for free-hanging installation and is RoHS compliant.

Feature Summary

• Constructed from Fair-Rite 43 material grade for effective high-frequency noise suppression
• Solid toroidal geometry provides a continuous magnetic path without gaps
• Compact dimensions suitable for space-constrained circuit board applications

Applications

• Common mode choke cores for data lines
• EMI suppression on small gauge wires
• Inductor core fabrication for RF circuits

Procurement Notes

Verify the specific material grade is 43 when sourcing, as Fair-Rite offers multiple compounds with distinct frequency characteristics. Confirm physical dimensions match the 3.05 mm ID and 5.83 mm OD requirements for your wire bundle or PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when high permeability at higher frequencies is required for noise attenuation. The 43 material is optimized for suppressing EMI in the 10 MHz to several hundred MHz range. Ensure the wire diameter fits within the 3.05 mm inner diameter clearance.

Part Context

This part belongs to the Fair-Rite solid toroid core family, which are non-split rings used primarily for winding custom inductors or chokes. Unlike openable cores, these require threading wires through the center hole during assembly, making them ideal for permanent installations where post-assembly modification is not needed.

Replacement Considerations

Substitute only with other Fair-Rite 43 material toroids sharing identical internal and external diameters. Verify that alternative suppliers provide the same NiZn compound properties to maintain impedance performance.
