A magnetic flux M flows inside the reed-shaped core 6, and a magnetic flux M flows near the surface.
1 passes through, but the external electrodes 4a+4b are the winding core 1.
And since it is directly attached to the cylindrical core 6, the magnetic flux M
In other words, the magnetic flux M1 may be influenced by the external electrodes 4a, 4t).
- Since C crosses 4b, when the magnetic flux changes, an eddy current is generated in the external electrodes 4a+4b, and the magnetic flux is lost, causing the Q of the C chip coil to drop and Lt.
