Ntau Hom Ntau Cov Peev Xwm
Capacitor yog cov khoom siv hluav taws xob uas khaws thiab tso tawm lub zog thiab siv nyob rau hauv yuav luag txhua cov khoom siv hluav taws xob thiab hluav taws xob xws li amplifier, computer motherboard, TV, xov tooj cua, lub tshuab cua thiab lwm yam khoom siv sib txawv ntawm cov pib ua hluav taws xob. Koj tuaj yeem pom ntau hom capacitors hauv khw thiab hom tseem ceeb yog ceramic, tantalum, aluminium electrolytic, polyester zaj duab xis, nyiaj mica thiab lwm yam. Capacitor nws muaj nws qhov tseem ceeb thiab siv hauv cov khoom siv hluav taws xob kom du ntws ntawm tam sim no thiab voltage.
Hauv ceramic capacitors ob txheej yog siv ib qho yog ua los ntawm ceramic thiab lwm qhov yog ua los ntawm cov hlau nrog tus rwb thaiv tsev uas yog hu ua dielectric. Cov hom capacitors no muaj lub zog loj thiab ruaj khov hauv qhov kub. Nws yog tus nqi ruaj ruaj capacitor txhais tau tias nws tuaj yeem khaws thiab tso tawm cov nqi hluav taws xob thiab muaj hluav taws xob ntau volumetric efficiency tsis. Ceramic capacitors tuaj nyob rau ntau tus duab thiab ntau thiab tsawg xws li ntau txheej, ib txheej disc, duab plaub txoj kab, cob txheej thiab lwm yam.
Tantalum capacitors muaj tus nqi qis dua, txo qis thiab ua haujlwm kub siab dua li lwm cov electrolytic capacitor. Tantalum capacitors yog me me thiab haum rau txhua yam khoom siv hluav taws xob. Vim muaj kev ua tau zoo tantalum capacitors yog nrov thiab me ntsis nqi tshaj txhuas capacitors. Aluminium capacitor yog lwm hom electrolytic capacitor uas pheej yig piv rau tantalum capacitor. Aluminium electrolytic capacitors yog tsim los ntawm aluminium foils ib txheej ntawm insulating aluminium oxide. Nyias txheej ntawm txhuas tso cai rau siab capacitance nyob rau hauv cov nyhuv li no ntau zog ceev. Electrolytic capacitor feem ntau yog siv nrog qhov tsis tshua muaj hluav taws xob thiab muaj peev xwm loj los khaws lub zog.
Zaj duab xis capacitors tseem hu ua zaj duab xis fais fab capacitors. Cov hluav taws xob hluav taws xob cov kab hluav taws xob muaj cov yeeb yaj kiab insulating yas ua dielectric. Nyob rau hauv zaj duab xis metalized zaj duab xis capacitors aluminium lossis zinc thov nyob rau saum npoo ntawm yas zaj duab xis. Ob txheej txheej pov tseg muaj qhov txhab nyob hauv lub tog raj kheej zoo li cua. Zaj duab xis capacitors yog siv feem ntau hauv cov khoom siv hluav taws xob. Axial, radial thiab SMD yog cov qauv loj ntawm zaj duab xis capacitors. Zaj duab xis capacitors yog siv dav hauv hluav taws xob hauv hluav taws xob, kev dhau los thiab kev siv txuas.
Nyiaj Mica capacitors yog feem ntau txhim khu kev qha vim muaj qhov ntsuas siab thiab ruaj khov. Cov hom capacitors muaj li ntawm mica ntawv coated nrog tso nyiaj hlau. Cov no yog tsawg me ntsis nyob rau hauv kev sib piv rau lwm hom capacitor. Nyiaj mica capacitors siv nyob rau qhov muaj ntau qhov muaj qhov hloov pauv qhov tsawg lub sijhawm yog xav tau.
