摘要： A common-mode filter with a drum type core including a core portion and flange portions. Electrodes are provided on the flange portions and a pair of wires are wound on the core portion. The wound pair of wires have ends connected to respective ones of the electrodes. Each of the flange portions has a groove between corresponding two of the electrodes and a separation protrusion for separating the groove into two lead-out groove portions. The pair of wires are wound on the core portion in such a distributed winding manner that an inter-wire distance between the pair of wires and a winding pitch between adjacent turns in each of the pair of wires are provided. The wires are one-by-one led out through the lead-out groove portions while separated by the separation protrusions so that the ends of the pair of wires are connected to respective electrodes.

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.
