Electronic device

An electronic device, comprising a blank with an insulating material, a conductive coil within the blank, and a first terminal and a second terminal exposed to a surface of the blank, wherein

• the blank has a top surface, a bottom surface, a first lateral surface, a second lateral surface, a front surface and a back surface, the top surface is parallel to the bottom surface, the first lateral surface is parallel to the second lateral surface, the front surface is parallel to the back surface, and a plane parallel to the top surface and the bottom surface, a plane parallel to the first lateral surface and the second lateral surface, and a plane parallel to the front surface and the back surface are mutually perpendicular;
• a distance between the first lateral surface and the second lateral surface is 0.42 mm or less, a distance between the front surface and back surface is 0.22 mm or less, and a distance between the top surface and the bottom surface is 0.22 mm or less;
• and
• a thickness-to-width ratio of at least one electrode layer of the conductive coil is 0.5 or more, and a cross section of the at least one electrode layer has a width of at least 15 μm and at most 30 μm, and a thickness of at least 15 μm and at most 40 μm.
