Fair-Rite Products Corp. part number 5943000501 is a solid ferrite toroid core manufactured from Material 43. The component features an inner diameter of 2.15 mm, an outer diameter of 3.95 mm, and an external height of 1.4 mm. It exhibits an inductance factor (AL value) of 885 nH with a tolerance of ±20%. Testing conditions for the AL value are specified at 10 kHz and magnetic flux densities below 10 Gauss.
Verify the specific Material 43 designation and physical dimensions against official Fair-Rite datasheets before integration. Confirm that the testing conditions for the inductance factor align with your circuit requirements. Ensure compliance with relevant environmental standards such as RoHS during the sourcing process.
Select this component when a compact toroidal geometry with high initial permeability is required. The Material 43 formulation provides effective noise attenuation in the lower frequency spectrum. Evaluate the physical constraints of the winding area against the 2.15 mm inner diameter to ensure adequate wire fit.
This component belongs to the standard ferrite toroid series produced by Fair-Rite Products Corp. Material 43 is a widely utilized nickel-zinc ferrite formulation known for its high permeability characteristics. These cores are commonly employed in electronic designs requiring efficient magnetic coupling and signal integrity maintenance.
Substitute parts must match the 2.15 mm inner diameter, 3.95 mm outer diameter, and 1.4 mm height. Verify that alternative suppliers provide Material 43 equivalents with comparable AL values and tolerances to maintain circuit performance.
