Common mode choke coil and high-frequency component
A common mode choke coil includes a first coil element and a second coil element connected in series between a first port and a second port, and a third coil element and a fourth coil element connected in series between a third port and a fourth port. With normal mode current flow through the first and second transmission lines, a first closed magnetic circuit forms in which magnetic flux passing through the first and second coil elements forms a closed loop, and a second closed magnetic circuit forms in which a magnetic flux passing through the third coil element and the fourth coil element forms a closed loop. With common mode current flow in the first and second transmission lines, a third closed magnetic circuit forms in which a magnetic flux passing through the first through fourth coil elements forms a closed loop.
