  • Inductor magnetic core and inductor using the same
    Patent number: 11430597
    Abstract: An inductor magnetic core and an inductor using the same are disclosed. The inductor magnetic core includes a middle column, an upper yoke, a lower yoke, and at least two high magnetically-permeable side columns. The middle column is disposed between a middle part of the upper yoke and a middle part of the lower yoke, a coil is wound the middle column, and a saturation magnetic flux density of the middle column is higher than that of the upper yoke and the lower yoke. The at least two high magnetically-permeable side columns are disposed in interval between the upper yoke and the lower yoke, and two ends of each high magnetically-permeable side column are connected to outer edges of the upper yoke and the lower yoke, respectively. The inductor magnetic core and the inductor of the present invention improves utilization of the yoke, and also provide compact structure and simple production.
