Fair-Rite Sintered Ferrite Powder: Flexible Magnetic Design Starts Here

Ferrites are at the heart of modern magnetic design. They shape fields, suppress noise, and define how energy moves through circuits. For decades, engineers have trusted Fair-Rite for reliable ferrite materials that perform under pressure.

Now, that same expertise is available in a new form: sintered ferrite powder. And Gateway is your direct channel to it, your authorised distributor for Fair-Rite’s next-generation magnetic materials.

What Makes Fair-Rite’s Sintered Ferrite Powder Different

The sintered ferrite powder from Fair-Rite starts with the same high-performance base material used in their solid cores. But instead of pressing the ferrite before firing, the powder is fired loose, leaving a fully densified but, discontinuous powder rather than a solid core.

This structural difference changes how the material behaves. It reduces permeability and saturation, creating a softer, more controllable magnetic response. For engineers working on experimental circuits, RF absorption, or hybrid magnetic designs, that difference is gold.

In short, sintered ferrite powder gives you ferrite-level magnetic performance without the constraints of a fixed geometry.

Designed for Experimentation and Real-World Production

Fair-Rite’s sintered ferrite powder is engineered for creative use and flexible integration. You can mix it, mould it, or blend it into composites. Typical applications include:

• Prototype development: Perfect for testing magnetic and inductive behaviour before finalising designs.
• Flux containment: Control or shape magnetic fields in open systems or custom housings.
• Inductance tuning: Adjust inductance in coil or choke assemblies by layering powder in resin.
• RF absorption: Incorporate into shielding compounds or absorptive coatings to damp high-frequency interference.

Available in MnZn (77) and NiZn (68) compositions, the powders cover a wide frequency range. MnZn for low to mid frequencies, NiZn for higher frequencies and lower loss designs.
