Abstract
An amorphous alloy-based magnetic core with reduced audible noise and a method of making the amorphous alloy-based magnetic core emanating low audible noise, including: placing the core with multiple layers of high strength tape on the core legs, wherein the tapes have a high tensile strength, high dielectric strength and high service temperature, resulting in reduced level of audible noise. When operated under optimum condition, the reduced level of audible noise is 6-10 dB less when compared with a same-size core that has been coated with resin instead.
