Microwave Ferrite Cores are essential components in various microwave circuits, renowned for enabling passive non-reciprocal transmission when magnetized with an external DC magnetic field. Traditionally, these cores were integrated into metallic waveguides with permanent magnets providing the necessary DC field, causing electromagnetic waves to experience phase shifts influenced by applied magnetic fields. Widely used in microwave isolators, circulators, switches, and RF frequency inductors, they offer excellent performance. Offering a cost-effective solution compared to other magnetic materials, Microwave Ferrite Cores boast high operating temperatures and strong corrosion resistance. Available in diverse shapes including Disc, Cylinder, Block, Ring, Countersunk, Segment, Trapezoid, Irregular shapes, and more, with customized options, they find applications in Dc motors, Loudspeakers, Magnetic Separators, Automotive Sensors, Educational tools, etc. With fast and large batch supply capabilities, these cores ensure Low Loss and High Frequency operation. Our product families include Spinel and Garnet types, ensuring reliability and performance across industries. FEerrites is committed to setting a high standard of excellence for industries integrating or utilizing magnetics technologies in our Microwave Ferrite Cores products.
