摘要： A transformer includes a magnetic core, a first coupling terminal, a second coupling terminal, a first winding, and one or multiple second windings. The magnetic core includes two opposed base parts, and five leg parts including first to fifth leg parts disposed within opposed surfaces of the base parts and magnetically coupling the base parts. The second and third leg parts are disposed with the first leg part interposed therebetween in a first direction. The fourth and fifth leg parts are disposed with the first leg part interposed therebetween in a second direction. The first winding is, in a direction from the first coupling terminal to the second coupling terminal, wound around the first to third leg parts in a first winding direction, and around the fourth and fifth leg parts in a second winding direction. The second winding/windings is/are wound around the leg parts except the first leg part.

摘要： A coil component includes a support substrate, a first coil and a second coil disposed on the support substrate to be spaced apart from each other, and a body including a first core and a second core penetrating through the first coil portion and the second coil portion and spaced apart from each other. The first coil portion has a first winding portion, forming at least one turn about the first core, and a first extension portion extending from one end portion of the first winding portion to surround the first core and the second core. The second coil has a second winding portion, forming at least one turn about the second core, and a second extension portion extending from one end portion of the second winding portion to surround the first core and the second core. A separation distance between a given turn of the first coil portion and an adjacent turn of the second coil portion is different from a separation distance between adjacent turns of the first coil portion.

摘要： In at least some implementations, a lamination stack includes a plurality of plates coupled together, each plate including at least one leg that collectively define a leg of the stack, with the leg of the stack arranged so that a wire coil may be arranged on the leg of the stack, and wherein the leg of the stack includes a location feature arranged to facilitate location of the stack relative to an adjacent component. In at least some implementations, the location feature may be integrally formed with at least one of the plates, and may be defined by a projection extending from a free end of at least one leg of the stack.

摘要： An ignition coil has primary and secondary coils, a central core and a pair of split cores. One of the split cores has a first opposing face orthogonal to a coil axial direction X facing a core front end face of the central core in the coil axial direction X. The respective split cores have second opposing surfaces mutually facing each other in a lateral direction Y at a rear end of the central core. At least one of the second opposing surfaces and one of rear end surfaces of the central core contacting the least one of the second opposing surfaces collectively constitute a pair of oblique surfaces and come to close to the other one of the second opposing surfaces in the lateral direction Y as a portion of each of the oblique surfaces recedes further from the first opposing face in the coil axial direction X.

摘要： An ignition coil includes a primary coil, a secondary coil, a center core, a magnet body and an outer peripheral core. The outer peripheral core is provided with a first opposite side, a second opposite side and a coupling side, the first opposite side facing the magnet body from an opposite side of the center core, the second opposite side facing the center core from the opposite side of the magnet body, the coupling side coupling the first opposite side with the second opposite side. The center core has a magnet side flange portion disposed at an end portion in a magnet body side, protruding in a protrusion direction. A thick portion is formed at both of a part of the first opposite side and a part of the coupling side, and a thickness of the thick portion being larger than a minimum thickness of the second opposite side.
