Abstract

The invention discloses a heavy-current high-frequency plane inductor and a making method thereof. The heavy-current high-frequency plane inductor comprises a coil and a magnetic core arranged at the outer part of the coil, wherein an insulation sheet is arranged between the coil and the magnetic core. According to the heavy-current high-frequency plane inductor and the making method thereof, by adopting a plane magnetic core with an E type section, and no conventional winding framework exists, the magnetic core and the coil are directly insulated and fixed through plugging the insulation sheet; the coil is formed by welding a single-turn coil through silver welding, thus the mechanical strength of the coil is ensured, and the impaction of a heavy current is met; each turn of coil can be processed into a thinner and larger plane, thus the flattening of the coil is ensured, the heat radiation area of the magnetic core and the surface of the coil is increased, and the efficiency of the inductor is increased; the inductor is capable of meeting the miniaturization demand.

Description

technical field [0001] The invention relates to an inductor and a manufacturing method thereof, in particular to a high-current high-frequency planar inductor and a manufacturing method thereof. Background technique [0002] As a commonly used magnetic component, the inductor is used for filtering, suppressing voltage and current spikes, protecting switching tubes, rectifier tubes and other components and capacitors to form a resonant circuit. With the rapid development of electronic information technology, various electronic devices have entered the era of lightness, thinness and miniaturization to reduce resource consumption. Therefore, it is required that the inductor be flattened and miniaturized to adapt to the development trend of light, thin and miniaturized electronic equipment. However, the design and production of high-current and high-frequency planar inductors are difficult due to the particularity of design, production process and use. Contents of the inventi...
