Ib co coil feem ntau yog hais txog ib ncig winding ntawm conductive hlau. Feem ntau siv rau coils muaj xws li motors, inductors, transformers, thiab voj antennas. Nyob rau hauv cov ntsiab lus ntawm hluav taws xob circuits, "coil" tshwj xeeb yog hais txog ib qho inductor. Nws yog tsim los ntawm winding ib tug neeg xyuas pib-hlau los ntawm xaim- xws li tias tus neeg strands tseem hluav taws xob rwb thaiv tsev ntawm ib leeg; cov tub ntxhais insulating tej zaum yuav hollow, los yog nws yuav muaj ib tug hlau core los yog ib tug hmoov sib nqus core. Cov khoom no feem ntau yog luv luv ua "inductor." Inductors tuaj yeem raug cais ntxiv rau hauv cov inductors ruaj khov thiab hloov pauv inductors; Ib qho ruaj khov inductor kauj tsuas yog hu ua "inductor" lossis "coil." Inductance yog cim los ntawm lub cim * L *, thiab nws cov units suav nrog Henry (H), millihenry (mH), thiab microhenry (µH), qhov twg 1 H=10³ mH=10⁶ µH.

Yam Khoom Parameters
Inductance
Inductance (*L*) sawv cev rau tus yam ntxwv ntawm lub kauj nws tus kheej thiab tsis muaj kev ywj pheej ntawm qhov loj ntawm qhov tam sim no ntws los ntawm nws. Nrog rau tshwj xeeb inductor coils (xws li xim -coded inductors), tus nqi tshwj xeeb inductance feem ntau tsis tau luam tawm ncaj qha rau ntawm lub kauj; Hloov chaw, qhov tivthaiv raug txheeb xyuas los ntawm ib lub npe qauv lossis kev xaiv.
Inductive Reactance
Inductive reactance (*X*L) ntsuas qhov ntev npaum li cas ntawm qhov inductor coil cuam tshuam qhov ntws ntawm alternating tam sim no (AC). Nws chav tsev yog Ohm (Ω). Kev sib raug zoo ntawm inductive reactance, inductance (*L*), thiab AC zaus (* f*) yog txhais los ntawm tus qauv: * X *L= 2π*fL*.
Qhov Zoo Tshaj Plaws (Q-factor)
Qhov Zoo Tshaj Plaws (*Q*) yog ib qho khoom siv lub cev siv los qhia qhov zoo ntawm lub kauj. Tus *Q*-factor yog txhais raws li qhov piv ntawm inductive reactance (*X*L) rau coil qhov sib npaug series tsis kam (*R*); uas yog: *Q*=*X*L / *R*.
Qhov siab dua qhov *Q*-tus nqi ntawm ib lub kauj, lub zog poob qis dua nyob rau hauv qhov cuam tshuam. Lub coil's *Q*- tus nqi yog cuam tshuam los ntawm ntau yam, suav nrog DC tsis kam ntawm cov xaim, dielectric losses nyob rau hauv lub coil qub (bobbin), poob vim los ntawm shielding enclosures los yog sib nqus cores, thiab cov teebmeem ntawm lub siab - zaus ntawm daim tawv nqaij. Feem ntau, *Q*- tus nqi ntawm ib lub kauj yog li ntawm ob peb kaum mus rau ntau pua. Distributed Capacitance
Lub capacitance uas twb muaj lawm nyob nruab nrab ntawm lub lem ntawm ib lub kauj, nruab nrab ntawm lub kauj thiab nws shielding enclosure, thiab nruab nrab ntawm lub kauj thiab nws baseplate yog hu ua distribution capacitance. Lub xub ntiag ntawm kev faib cov capacitance txo cov kauj Q-factor thiab degrades nws stability; yog li ntawd, qhov qis dua qhov faib capacitance ntawm lub kauj, qhov zoo dua.
