Cov kua lead-type electrolytic capacitor yog hom capacitor dav siv hauv cov khoom siv hluav taws xob. Nws cov qauv feem ntau muaj lub plhaub aluminium, electrodes, kua electrolyte, leads, thiab sealing Cheebtsam. Piv nrog rau lwm hom electrolytic capacitors, kua lead-type electrolytic capacitors muaj cov yam ntxwv tshwj xeeb, xws li siab capacitance, cov yam ntxwv zoo heev, thiab qis sib npaug series tsis kam (ESR).
Basic Structure thiab Txoj Cai Ua Haujlwm
Cov kua lead-hom electrolytic capacitor feem ntau muaj anode, cathode, thiab dielectric. Lub anode feem ntau yog ua los ntawm high-purity txhuas, uas undergoes anodizing los ua ib tug nyias txheej ntawm aluminium oxide zaj duab xis. Cov yeeb yaj kiab no ua raws li dielectric ntawm lub capacitor. Lub cathode feem ntau yog ua los ntawm txhuas ntawv ci thiab ib qho electrolyte, nrog rau cov electrolyte ua ob qho tib si cov khoom siv cathode thiab nruab nrab rau dielectric regeneration. Lub xub ntiag ntawm electrolyte tso cai rau lub capacitor kom muaj kev ua tau zoo txawm tias nyob rau hauv qhov kub thiab txias.
Cov qauv siv lead ua qhia tau hais tias qhov capacitor txuas mus rau lub voj voog los ntawm kev coj. Cov hlau lead no feem ntau yog ua los ntawm tinned tooj liab hlau, ua kom muaj kev sib txuas hluav taws xob zoo thaum lub sij hawm soldering.

Yog li ntawd, lawv feem ntau yog siv nyob rau hauv circuits uas yuav tsum tau high-frequency stability thiab tsis muaj suab nrov, xws li hluav taws xob circuits thiab khoom siv sib txuas lus.
4. **Long Lifespan**: Los ntawm kev siv cov khoom siv hluav taws xob zoo thiab cov txheej txheem tsim khoom, cov kua lead-type electrolytic capacitors feem ntau muaj lub neej ua haujlwm ntev. Raws li kev ua haujlwm ib txwm muaj, lawv lub neej ntev tuaj yeem ncav cuag ntau txhiab mus rau kaum txhiab teev, ua tau raws li qhov xav tau ntawm cov ntawv thov feem ntau.
Cov cheeb tsam thov
Cov kua lead-type electrolytic capacitors yog dav siv nyob rau hauv ntau yam khoom siv hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv lub hwj chim circuits, suab khoom, kev sib txuas lus, thiab automotive electronics. Lawv feem ntau yog siv hauv kev lim dej, sib txuas, sib txuas, thiab lub zog cia hluav taws xob los txhim kho kev ua haujlwm thiab kev ntseeg siab ntawm cov khoom siv.
Hauv cov ntsiab lus, vim lawv lub peev xwm siab, tsis tshua muaj ESR, cov yam ntxwv zoo zaus, thiab lub neej ntev, cov kua lead-hom electrolytic capacitors tau dhau los ua cov khoom tseem ceeb hauv cov khoom siv hluav taws xob. Nrog kev nce qib hauv thev naus laus zis, kev ua haujlwm thiab kev siv ntau yam ntawm cov capacitors yuav txuas ntxiv nthuav dav.
