Lub luag haujlwm ntawm electrolytic capacitor yog dab tsi hauv kev hloov cov khoom siv fais fab?
Lub luag haujlwm ntawm electrolytic capacitors hauv kev hloov cov khoom siv hluav taws xob yog: bypass, decoupling, filtering, zog cia.
1, bypass capacitors yog lub zog cia khoom siv uas muab lub zog rau cov cuab yeej hauv zos, uas tuaj yeem tawm ntawm cov khoom siv hluav taws xob thiab txo qhov kev thov. Zoo li lub roj teeb me me, cov khoom siv hla dhau tuaj yeem raug them thiab tawm mus rau lub cuab yeej.
2, decoupling: tshwj xeeb yog hais txog kev tshem tawm suab nrov ntawm lub zog nti lub raj pin, lub suab nrov yog tsim los ntawm nti nws tus kheej ua haujlwm. Configuration decoupling capacitors tuaj yeem raug tshem tawm vim kev hloov pauv ntawm lub suab nrov tsim los ntawm cov ntawv luam tawm Circuit Board yog ib qho kev coj ua ntawm kev ntseeg siab tsim.
3, filtering: capacitors hloov voltage variations rau hauv tam sim no kev hloov, qhov ntau zaus, qhov ntau dua lub ncov tam sim no, yog li buffering qhov voltage. Lim yog cov txheej txheem ntawm kev them nyiaj, tso tawm.
Electrolytic capacitor yog ib hom capacitor, hlau ntawv rau tus ncej zoo (aluminium los yog tantalum), thiab tus ncej zoo ze rau cov hlau oxide zaj duab xis (aluminium oxide lossis tantalum pentoxide) yog dielectric, cathode los ntawm cov khoom siv hluav taws xob, electrolyte ( electrolyte tuaj yeem ua kua lossis khoom) thiab lwm yam khoom siv ua ke, vim tias cov electrolyte yog qhov tseem ceeb ntawm cathode, electrolytic capacitor yog li lub npe. Nyob rau tib lub sij hawm electrolytic capacitors zoo thiab tsis zoo yuav tsis txuas nrog qhov tsis ncaj ncees lawm. Aluminium electrolytic capacitor tuaj yeem muab faib ua plaub pawg: txhuas electrolytic capacitors; bullhorn txhuas electrolytic capacitor; bolted aluminium electrolytic capacitor; Khoom lub xeev aluminium electrolytic capacitor.
Feem ntau faults ntawm electrolytic capacitor
Feem ntau ua txhaum ntawm electrolytic capacitors yog qhov muaj peev xwm txo qis, muaj peev xwm ploj mus, tawg thiab tawg, thiab lwm yam, uas lub peev xwm hloov pauv yog tshwm sim los ntawm electrolytic capacitor nyob rau hauv cov txheej txheem ntawm kev siv lossis ua kom sov nws cov electrolyte sab hauv maj mam qhuav (feem ntau hais tias qhov siab. Qhov kub thiab txias muaj peev xwm txo), thiab kev tawg thiab tawg feem ntau yog tshwm sim los ntawm qhov ntxiv voltage siab dhau los yog lub capacitor nws tus kheej tsis zoo.
