Latest Patents

Toshiaki Tomozawa holds a patent for a low-loss magnetic oxide material and the method for making it. This patent describes a Ni type ferrite material characterized by a low magnetic loss. The material is created by adding MnO in an amount of 0.1 to 10 mol % to a ferrite composition containing Fe O in 40 to 50 mol %, ZnO in 20 to 33 mol %, CuO in 2 to 10 mol %, and NiO in the remainder. This Ni type ferrite material is particularly suited for use in coil components as a core material due to its reduced magnetic loss compared to prior materials. Additionally, it possesses high electric resistance, allowing for direct coil winding on the core, which leads to a reduction in both size and weight of the coil component.
