Abstract

An electric coil device includes a terminal unit and a coil module. The terminal unit includes a block and multiple terminals. The coil module is mounted to the block and includes first and second winding cores, two first wires and two second wires. Each of the first wires has a transformer wire segment wound on the first winding core, and an inductor wire segment wound on the second winding core. The transformer wire segment of each of the first wires is electrically connected to a respective one of the terminals, and the inductor wire segment of each of the first wires is electrically connected to the respective one of the terminals, thereby achieving the functions of a transformer and a common-mode choke.
