5943001101

Overview

Fair-Rite Products Corp. part number 5943001101 is a ferrite toroidal core utilizing Mix 43 material, also designated as FT-50A-43. It features an inner diameter of 7.9 mm (0.312 inches), an outer diameter of 12.7 mm (0.500 inches), and a height of 5.08 mm (0.200 inches). The component is designed for RF applications including filters, chokes, and baluns, offering high permeability and stable performance characteristics.

Feature Summary

• Utilizes Mix 43 ferrite material for high permeability
• Provides stable performance in RF circuits
• Suitable for constructing chokes and baluns

Applications

• RF filter construction
• Inductor choke winding
• Balun transformer assembly

Procurement Notes

Verify the specific Fair-Rite catalog designation to ensure compatibility with required impedance curves. Confirm that the physical dimensions match the intended winding form factor. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the supplier provides original manufacturer documentation for quality assurance purposes.

Selection Notes

Select this component when high permeability is required for efficient magnetic coupling in compact RF designs. The FT-50A size offers a balance between core volume and winding space. Consider the frequency-dependent loss characteristics of Mix 43 material to ensure optimal performance at the target operating frequency range for the specific circuit application.

Part Context

This part belongs to the Fair-Rite FT series of standard toroidal cores. The '59' prefix indicates a toroid shape, while '43' denotes the specific ferrite composition optimized for frequencies typically ranging from 1 MHz to 30 MHz. It is a widely used standard core in amateur radio and general RF engineering.

Replacement Considerations

Equivalent parts include other manufacturers' FT-50A sized cores using Mix 43 material. Verify that substitute components maintain identical outer diameter, inner diameter, and height specifications to fit existing tooling or bobbins.
