Variable inductor and method |
摘要 |
A variable inductor includes two substantially meandering coils with trimming electrodes disposed therebetween on an insulating substrate. The trimming electrodes are located outside the region where the coils are provided. The two coils and the trimming electrodes are electrically connected. The trimming electrodes are exposed to a laser beam and thus, are trimmed one by one so as to vary the inductance.
