Lub hollow inductor kauj yog ib qho khoom siv inductor uas tsis tas yuav muaj cov tub ntxhais sib nqus. Nws tso siab rau cov coil windings thiab cov huab cua nruab nrab hauv kom ua tiav cov teebmeem inductance. Cov qauv tsim no muaj qhov tsis tshua muaj sib nqus hysteresis poob, ntau zaus, thiab siab linearity, ua rau nws siv dav hauv kev sib txuas lus, RF kav hlau txais xov, khoom siv kho mob, thiab lwm yam.
