COMMON-MODE CHOKE COIL

PROBLEM TO BE SOLVED: To provide a common-mode choke coil which reduce variations in characteristic impedance by keeping intervals of conductors constant. SOLUTION: A core 3 has a 1st cut 33a near the intersection of a first side face 33 and the back of a collar 4 by slightly recessing the surface t...

Summary:PROBLEM TO BE SOLVED: To provide a common-mode choke coil which reduce variations in characteristic impedance by keeping intervals of conductors constant. SOLUTION: A core 3 has a 1st cut 33a near the intersection of a first side face 33 and the back of a collar 4 by slightly recessing the surface toward a 2nd side face 34, a 1st corner is formed at a connection portion between the 1st cut 33a and back, and a second corner 33c is formed at a connection place between the 1st side face 33 and first cut 33a. The second side face 34 also has a second cut 34a, a third corner 34b, and a fourth corner 34c formed similarly. A first conductor 6 and a second conductor 7 extends from a wiring place of a first electrode 8 to the first cut 33a, and is arranged along the first corner and second corner 33c to be wound. Then they are wound up to the second cut 34a arranged along the fourth corner 34c and a third corner 33b, and wired to the second electrode 9. COPYRIGHT: (C)2006,JPO&NCIPI
