Cov qauv thiab cov yam ntxwv ntawm inductors

Inductors feem ntau yog tsim los ntawm lub cev pob txha, winding, shielding cover, ntim khoom, magnetic core lossis hlau core, thiab lwm yam.

1. Skeleton: Skeleton hais txog kev txhawb nqa rau winding coils. Qee qhov loj ruaj khov lossis kho tau inductors (xws li oscillation coils, choke coils, thiab lwm yam) feem ntau yog qhwv nrog enameled hlau (los yog gauze qhwv hlau) nyob ib ncig ntawm lub cev pob txha, thiab ces sib nqus los yog tooj liab cores, hlau cores, thiab lwm yam. sab hauv kab noj hniav ntawm lub cev pob txha kom nws inductance. Lub cev pob txha feem ntau yog ua los ntawm cov yas, bakelite, lossis ceramic, thiab tuaj yeem ua rau cov duab sib txawv raws li qhov xav tau tiag tiag. Cov inductors me me (xws li xim coded inductors) feem ntau tsis siv lub cev pob txha, tab sis hloov ncaj qha qhwv cov hlau enameled nyob ib ncig ntawm cov hlau nplaum. Hollow inductors (tseem hu ua unbound coils los yog hollow coils, feem ntau siv nyob rau hauv high-frequency circuits) tsis tas yuav tsum tau sib nqus cores, skeletons, thiab shielding npog. Hloov chaw, lawv raug mob nyob ib ncig ntawm cov pwm ua ntej tshem cov pwm, thiab ib qho kev ncua deb yog kos ntawm cov coils.

2. Winding: Ib qho winding yog hais txog ib txheej coils nrog cov haujlwm tshwj xeeb, uas yog qhov tseem ceeb ntawm cov inductor. Lub winding tuaj yeem muab faib ua ib txheej thiab ntau txheej. Muaj ob hom ntawm ib txheej winding: kaw winding (thaum winding, cov xov hlau raug mob ib qho los ntawm ib qho) thiab lub caij winding (thaum winding, txhua lub xaim yog spaced ntawm ib qhov deb); Muaj ntau txoj hauv kev rau ntau txheej txheej winding, xws li txheej ca winding, random winding, thiab honeycomb winding.

3. Sib nqus cores thiab tuav: Sib nqus cores thiab tuav feem ntau yog ua los ntawm cov ntaub ntawv xws li npib tsib xee zinc ferrite (NX series) lossis manganese zinc ferrite (MX series), uas muaj ntau yam duab xws li "Kuv" zoo, kem duab, cap puab. , "E" puab, thiab tuaj yeem tsim.

4. Cov tub ntxhais hlau: Cov khoom siv hlau feem ntau suav nrog cov ntawv silicon steel, permalloy, thiab lwm yam, thiab lawv cov tsos yog feem ntau "E" hom.

5. Kev tiv thaiv npog: Txhawm rau kom tsis txhob muaj cov hlau nplaum uas tsim los ntawm qee qhov inductors thaum lub sijhawm ua haujlwm los ntawm kev cuam tshuam rau kev ua haujlwm ib txwm muaj ntawm lwm cov khoom siv hluav taws xob thiab cov khoom siv, lub npov hlau npog (xws li oscillation coil ntawm lub xov tooj cua semiconductor) tau ntxiv. Kev siv cov shielded inductor yuav ua rau kom poob ntawm lub kauj thiab txo tus nqi Q.

6. Cov ntaub ntawv ntim khoom: Tom qab qee qhov inductors (xws li xim code inductors, xim nplhaib inductors, thiab lwm yam) raug mob, lub coil thiab cov tub ntxhais sib nqus raug kaw nrog cov khoom ntim. Cov khoom ntim yog ua los ntawm cov yas lossis epoxy resin.
