About Fair-Rite
Fair-Rite is a long-established US maker of ferrite components, with a reputation built on nearly seven decades of material science and manufacturing expertise. The company focuses on ferrite-based parts that help engineers manage electromagnetic behaviour in electronic systems, whether reducing interference or shaping magnetic fields for power and signal applications.
What Fair-Rite Make
Fair-Rite’s portfolio centres on ferrite components engineered for suppression, inductive and power-magnetic functions. Its products include:
- Ferrite cores in many shapes (toroidal, E core, rod, planar and others) used as the magnetic heart of inductors, transformers and chokes.
- Cable suppression cores and split-core (snap-on) designs that clamp around cables to reduce conducted electromagnetic interference (EMI).
- Surface-mount and through-hole beads used on PCB tracks to suppress noise at specific frequency ranges.
- Flat and round ferrite materials for custom suppression assemblies or engineered magnetic components.
- Ferrite kits that let designers prototype and evaluate different core materials and geometries quickly.
With both catalogue products, and bespoke designs available through The Ferrite Machine Shop, support is available to help teams refine core geometries and materials to meet electrical and mechanical requirements before full production.
Applications & Industries
Ferrite materials from Fair-Rite are essential where magnetic and electromagnetic behaviour influences circuit performance:
- EMI and RFI Suppression: Ferrite beads and cable cores filter high-frequency noise in power rails, data lines and connectors.
- Power Electronics: Cores in transformers and inductors help shape current flow, reduce losses and support switched-mode power supplies (SMPS).
- Automotive Systems: Components suppress noise and protect circuits in electric power systems, sensors and control modules.
- Industrial and Communications Gear: Ferrite parts improve signal integrity in data networks, machine controls and industrial automation.
- Medical and Aerospace: High-reliability suppression and magnetic components support sensitive measurement and defence designs.
Fair-Rite’s products help designers handle interference challenges and magnetic needs across consumer, commercial and regulated sectors, from smart devices to complex power systems.
