Abstract
Disclosed is a low-priced and small-sized magnetic core for an inductor suitable for a high frequency signal and a large-current signal. The magnetic core is modified from a conventional EP type magnetic core. A recess is integrally formed with a peripheral portion of the magnetic core when it is shaped. A bottom portion and the peripheral portion are extended toward an opening portion to an extent of about 70 percentages of a length measured from a center of the center portion to an internal surface of the peripheral portion. The peripheral portion opposite to the opening portion has a uniform thickness. The magnetic core is designed to facilitate its surface mounting onto a PCB.
