Abstract:
A surface mountable coil comprising:a core including a body portion and two raised portions disposed at two opposite ends of the body portion, each of the raised portions having an end surface and a peripheral surface, wherein the peripheral surface has corner regions and is provided with cutaway portions at the corner regions; a winding wire wound around the body portion; a pair of base electrodes, each of the base electrodes being disposed on the peripheral surface and the end surface of one of the raised portions, and two ends of the winding wire being connected to the base electrodes respectively; an encapsulating member extending from a portion of one base electrode to a portion of the other base electrode to thereby cover the region therebetween while exposing a part of the base electrode on each peripheral surface; and a pair of terminal electrodes respectively covering the exposed base electrodes and end portions of the encapsulating member on the peripheral surfaces of the raised portions, wherein the end portions of the encapsulating member on the peripheral surfaces have peak portions extending toward the end surfaces of the raised portions and valley portions retracting away from the end surfaces.
