| description | Provided is a coil component. A coil component, according to an embodiment of the present invention, has 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. Moreover, the present invention enables highly efficient conductivity and radiation of the heat generated from the coil component and excellent insulation of the outer side of the coil component, thereby preventing electrical shorting due to a short circuit and the like. |
