Variabel induktansspole |
摘要 |
A variable inductor includes a coil and an inductance trimming member disposed on an insulating substrate. The inductance trimming member is disposed outside of an area where the coil is located. By exposing the inductance trimming member to a laser beam, cross rail members of the inductance trimming member are trimmed one by one, thus varying the inductance. |
