Kapacitor-ka nooca ledhka ah ee dareeraha ah waa nooc kapacitor ah oo si weyn loogu isticmaalo aaladaha elektiroonigga ah. Qaab dhismeedkeedu wuxuu ka kooban yahay qolof aluminium ah, electrodes, electrolyte dareere ah, hogaanka, iyo qaybaha xidhitaanka. Marka la barbardhigo noocyada kale ee capacitors electrolytic, dareeraha nooca rasaasta nooca electrolytic capacitors waxay leeyihiin sifooyin gaar ah, sida capacitance sare, sifooyinka soo noqnoqda aad u fiican, iyo iska caabin hoose u dhigma taxane ah (ESR).
Qaab dhismeedka aasaasiga ah iyo mabda'a shaqada
Kapacitor-ka nooca ledhka ee dareeraha ah wuxuu inta badan ka kooban yahay anode, cathode, iyo dielectric. Anode-ku wuxuu inta badan ka samaysan yahay aluminium saafi ah oo sarreeya, kaas oo la maro anodizing si uu u sameeyo lakab khafiif ah oo aluminium oksidh ah. Filimkani wuxuu u shaqeeyaa sidii koronto-dhaliyaha capacitor-ka. Kathode-ku wuxuu caadi ahaan ka samaysan yahay aluminium aluminium iyo electrolyte, iyada oo korantadu u adeegto labadaba walxaha cathode iyo dhexdhexaad ah dib-u-soo-nooleynta dielectric. Joogitaanka elektrolytka waxay u ogolaataa capacitor inuu ilaaliyo waxqabadka wanaagsan xitaa heerkulka sare.
Naqshadaynta nooca rasaasta ayaa tilmaamaysa in kapacitor-kani uu ku xidho wareegga iyada oo loo marayo raadad. Dariiqyadani waxay caadi ahaan ka samaysan yihiin silig naxaas ah oo qasacadaysan, iyagoo hubinaya isku xidhka koronto ee wanaagsan inta lagu jiro alxanka.
Faa'iidooyinka Muhiimka ah
1. ** Capacitance Sare ***: Kaabciilayaasha nooca ledhka ah ee dareeraha ah waxay bixiyaan awood sare, taasoo ka dhigaysa mid aad waxtar ugu leh shaandhaynta, isku xidhka, iyo codsiyada kaydinta tamarta. Waxay ku siin karaan awood weyn oo mug yar ah, taas oo si gaar ah muhiim ugu ah aaladaha elektiroonigga ah ee xaddidan.
2. ** Iska-caabbinta Taxane Hoosaysa (ESR) ***: Isticmaalka dareeraha dareeraha ah wuxuu keenaa ESR hooseeya, hoos u dhigista awoodda lumista iyo soo saarista kulaylka, taas oo hagaajinaysa waxtarka iyo xasilloonida capacitor. Habkani waxa uu ka dhigayaa iyaga oo caan ku ah sahayda korantada beddelka-sare ee soo noqnoqda, qalabka maqalka, iyo codsiyada kale ee u baahan waxqabadka soo noqnoqda ee sarreeya.
3. ** Tilmaamaha Soo noqnoqoshada aad u Wanaagsan ***: Xiriyeyaashani waxay soo bandhigaan waxqabad heer sare ah, iyagoo si wax ku ool ah u xakameynaya buuqa soo noqnoqda. Sidaa darteed, waxaa caadi ahaan loo isticmaalaa wareegyada u baahan xasilloonida soo noqnoqda iyo qaylada hoose, sida wareegyada korantada iyo qalabka isgaarsiinta.
4. ** Cimri dheer ***: Adigoo isticmaalaya koronto-yaqaanno tayo sare leh iyo geeddi-socod-soo-saar horumarsan, kuwa dareeraha ah ee nooca-lead-ka-qaadayaasha guud ahaan waxay leeyihiin nolol adeeg dheer. Xaaladaha shaqada ee caadiga ah, cimrigoodu wuxuu gaari karaa dhowr kun ilaa tobanaan kun oo saacadood, iyagoo buuxinaya dalabaadka codsiyada badankooda.
Goobaha Codsiga
Dareereyaasha nooca elektrolytic-ka ah ee dareeraha ah ayaa si weyn loogu isticmaalaa aaladaha elektiroonigga ah ee kala duwan, gaar ahaan wareegyada korantada, qalabka maqalka, aaladaha isgaarsiinta, iyo elektiroonigga baabuurta. Caadi ahaan waxaa loo adeegsadaa shaandhaynta, isku-xidhka, kala-goynta, iyo wareegyada kaydinta tamarta si kor loogu qaado waxqabadka iyo isku halaynta qalabka.
Marka la soo koobo, iyadoo ay ugu wacan tahay awoodooda sare, ESR hoose, sifooyinka soo noqnoqda ee aad u wanaagsan, iyo cimriga dheer, capacitors nooca ledhka ah ee dareeraha ah waxay noqdeen qaybo lagama maarmaanka u ah aaladaha elektiroonigga ah. Horumarka tignoolajiyada, waxqabadka iyo kala duwanaanta codsiga ee capacitors-yadan ayaa sii wadi doona inay balaarto.
