NOISE-SUPPRESSING COMPOSITE MAGNETIC POWDER |
摘要 |
The object is to provide a composite magnetic powder for noise suppression to give a noise suppressor having ability to suppress the noise in a wide range from a low frequency through a high frequency while suppressing heat generation by reducing a dielectric constant loss on the high frequency side, and in order to attain the object, there is employed a composite magnetic powder for noise suppression in which the surface of a metallic powder is coated with a fine particle having a high dielectric constant and a binder resin or the like. By using this composite magnetic powder for noise suppression, there can be provided a noise suppressor excellent in ability to suppress the noise in a wide frequency region. |
