Taw qhia rau lub ntsiab parameter ntawm inductors

Main parameter ntawm inductor

1. Inductance

Inductance L, tseem hu ua tus kheej inductance coefficient, yog lub cev muaj nuj nqis siv los sawv cev rau tus kheej inductance peev xwm ntawm cov khoom siv inductive. Thaum cov hlau nplaum sib nqus dhau los ntawm lub kauj hloov, lub zog hluav taws xob induced yog tsim nyob rau hauv lub kauj, uas yog qhov tshwm sim ntawm electromagnetic induction (kev paub txog electromagnetic induction yuav kawm nyob rau hauv tshooj tom ntej). Qhov loj ntawm electromotive quab yuam yog proportional rau tus nqi ntawm magnetic flux hloov thiab tus naj npawb ntawm coil tig. Cov kev taw qhia ntawm tus kheej induced electromotive quab yuam ib txwm cuam tshuam qhov kev hloov ntawm thawj tam sim no, ib yam li ib co coil muaj inertia, thiab qhov loj ntawm lub electromagnetic inertia yog sawv cev los ntawm inductance L. International System of Units (SI) unit ntawm L, H. (Henry), feem ntau yog siv los ua mH (milliHeng) thiab μ H (Weiheng), nws txoj kev sib raug zoo yog:

Zoo li cov capacitors, qhov inductance ntawm hollow inductors (tseem hu ua linear inductors) kuj nyob ntawm lawv tus kheej cov qauv thiab tsis cuam tshuam txog seb lub coil muaj zog lossis qhov loj ntawm qhov tam sim no.

2. Rated tam sim no

Feem ntau yog hais txog DC tam sim no tus nqi uas tso cai rau lub sijhawm ntev dhau los ntawm cov khoom siv inductive. Thaum xaiv cov khoom siv inductive, lawv cov nqi tam sim no feem ntau yog me ntsis ntau dua li qhov siab tshaj plaws tam sim no ntws los ntawm Circuit Court.

3. Qhov zoo tshaj plaws

Qhov zoo tshaj plaws, tseem hu ua Q tus nqi, yog sawv cev los ntawm tsab ntawv Q. Tus nqi Q siab qhia tau tias poob qis thiab ua haujlwm siab hauv kab kos duab. Rau kev xaiv zaus zaus, yuav tsum muaj Q tus nqi siab. Hauv xov tooj cua, Q tus nqi yog siab, qhov kev xaiv zoo, thiab nws tsis yooj yim rau hla cov channel.
