<p>A coil block (300) and an electronic device using the same are provided. The coil block (300) includes a first coil (332), a second coil (334), a core (310) having an intermediate layer (320) for separating the first coil (332) and the second coil (334) from each other, and a shield (340) for shielding the first coil (332), the second coil (334), and the intermediate layer (320), wherein the first coil (332) and the second coil (334) have the same winding direction. According to the coil block (300) and the electronic device, the filtering can be performed without any inductance offset even if the PWM signal having the inversed phase or the same phase is inputted. Also, since two windings can be wound on to one core (310) using a common coil, the cost and the size of the coil block (300) can be reduced.</p> |
