摘要： A method for manufacturing spherical ceramic powder is provided. The method includes essentially a spray drying step and a sintering step. In the spray drying step, a spray nozzle is used to spray slurry containing powdered raw material consisting essentially of ceramic ingredients to form liquid droplets, and liquid contents in the liquid droplets are heated and removed to obtain ceramic granular powder. In the sintering step, the ceramic granular powder is sintered to form spherical ceramic powder. The method provides ceramic powder having a mean particle size of about 1-50 μm and a sphericity of about 0.8 or higher, which is suited for mixing with resin material to form a compound. The ceramic powder has high dispersant and filling properties against the resin material.

摘要： A feed-through EMI filter includes a hollow outer conductor, an inner conductor passing through the outer conductor, and a composite magnetic material of magnetic metal flakes disposed between the outer conductor and the inner conductor. Both ends of the outer conductor are closed by insulating lids supporting the inner conductor in a feed-through arrangement. The composite magnetic material has a higher complex relative permeability at GHz frequencies than ferrites and produces a large insertion loss.
