Abstract: A coil component having a magnetic core, a bobbin accommodating the magnetic core, and at least one pair of coils wound around the outer part of the bobbin. The bobbin is implemented as a heat radiating member comprising: a polymer matrix; and graphite-nano metal composites which are provided in a plurality, are dispersed on the polymer matrix, and have nano-metal particles bonded to the surface of graphite. Accordingly, the heat generated from a coil component due to an applied current can most quickly and efficiently be conducted and radiated outside, and thus degrading of common-mode-noise rejection function is prevented and a differential signal can substantially be passed without attenuation. In addition, in spite of the heat generated from the coil component or external physical and chemical stimulation, heat radiating properties can last for a long time.

Abstract: In a magnet stack, an eddy current channel is cut off by an insulating layer in an insulating region of facing surface regions of the pair of magnets. Meanwhile, in a conducting region of the facing surface region of the pair of magnets, electrons can move between the pair of magnets via a conductor, and heat can be exchanged between the pair of magnets by the movement of electrons. Therefore, in the magnet stack, by cutting off the eddy current channel in the insulating region of the facing surface region of the pair of magnets, the degradation in magnet performance is suppressed and the cooling efficiency of the magnet is enhanced in the conducting region.
