摘要： A common mode choke coil is provided with first and second coil conductors that are magnetically coupled to each other, a third coil conductor that is electrically connected in series to the first coil conductor and substantially not magnetically coupled to the first coil conductor, a fourth coil conductor that is electrically connected in series to the second coil conductor and substantially not magnetically coupled to the second coil conductor, a first contact conductor for connecting the third coil conductor with the inner end of the first coil conductor, and a second contact conductor for connecting the fourth coil conductor with the inner end of the second coil conductor. The third coil conductor and the fourth coil conductor are substantially not magnetically coupled, and are in a linear symmetrical relationship based on a prescribed center line.

摘要： A transformer that improves the DC superposition characteristic without incurring eddy-current losses. In the transformer, a part of a plate-like core opposing a top face of a flange of a drum core is formed with a first opposing portion opposing none of input and output terminals and a second opposing portion opposing the input and output terminals. A first gap is formed between the top face and the first opposing portion by a spacer. A second gap greater than the first gap is formed by a recess of the plate-like core provided so as to correspond to the second opposing portion. This allows magnetic fluxes to pass between the top face and the first opposing portion where the gap is formed and inhibits them from passing between the plate-like core and the input and output terminals where the second gap greater than the first gap is formed.

摘要翻译： 一种改善直流叠加特性而不产生涡流损耗的变压器。 在变压器中，与鼓芯的凸缘的顶面相对的板状芯部的一部分形成有与输入和输出端子相对的第一相对部分和与输入和输出端子相对的第二相对部分。 通过间隔件在顶面和第一相对部分之间形成第一间隙。 大于第一间隙的第二间隙由设置成对应于第二相对部分的板状铁芯的凹部形成。 这允许磁通在顶面和形成间隙的第一相对部分之间通过，并且阻止它们在板状芯与形成第二间隙的第二间隙之间的输入和输出端之间通过。
