ABSTRACT:
An inductor with the characteristic of resisting high current comprising a conductor coil and a magnet envelope, the magnet envelope tightly wraps the periphery of the conductor coil and forms the main body of the inductor, and the two extending parts of the conductor coil extend to outside of the main body of the inductor, forming terminal electrode. As of the manufacturing method, it includes the part of toroid coil and the extending parts composing the conductor coil. After the toroid coil part is winded into rings, the unwinded wire ends form the extending parts. Through magnet envelope die-casting and wrapping the molded magnet core of the conductor coil to form the main body of the inductor, and the extending parts of the conductor coil extend to outside of the main body to form the terminal electrode.
