Kutheni ii-capacitors zihlala zisilela?

I-Aluminiyam i-electrolytic capacitorsziyinxalenye ebalulekileyo yezixhobo zombane ezininzi kwaye zidlala indima ephambili ekugcineni nasekukhupheni amandla ombane. Nangona kunjalo, ngaphandle kokubaluleka kwazo, ii-capacitors zihlala zisilela, zibangela ukusilela kunye nokonakalisa inkqubo yonke. Ukuqonda izizathu zokungaphumeleli kwe-capacitor kubalulekile ekuqinisekiseni ukuthembeka kunye nexesha elide lezixhobo zombane.

Kukho izizathu ezininzi zokuba kutheni ii-capacitors zihlala zisilela, enye yezona zinto ziqhelekileyo kukusetyenziswa kwei-aluminium electrolytic capacitors. Ezi capacitors zisetyenziswa kakhulu kwiisekethe ngenxa yobuchule bazo obuphezulu, ixabiso eliphantsi, kunye nomgangatho ophezulu wombane. Nangona kunjalo, xa kuthelekiswa nezinye iintlobo ze-capacitors, zinobomi obunqamlekileyo, obunokubangela ukungaphumeleli rhoqo kwizixhobo zombane.

Esinye sezizathu eziphambili ze-aluminium electrolytic capacitors zisilela kukuba novakalelo lokuguquguquka kobushushu. Ezi capacitors zivakalelwa kakhulu kwiinguqu zeqondo lokushisa, kwaye ukuvezwa kwamaqondo aphezulu aphezulu kunokubangela ukuba i-electrolyte ngaphakathi kwe-capacitor yome, okubangela ukulahlekelwa kwe-capacitance kunye nokunyuka kokuvuza kwangoku. Oku kunokubangela ukuba i-capacitor ithobe kwaye ekugqibeleni ibangele ukuba ingaphumeleli.

Enye into ebangela ukungaphumeleli kwe-aluminium electrolytic capacitors kukuthambekela kwabo ukuthotywa kwexesha. I-electrolyte esetyenziswa kwezi capacitors ichaphazeleka kwimichiza, enokuthi ibangelwe zizinto ezahlukeneyo ezifana namaqondo obushushu aphezulu okusebenza, uxinzelelo lombane, kunye nokuvezwa kungcoliseko lokusingqongileyo. Njengoko i-electrolyte iyancipha, i-capacitance kunye ne-ESR (i-requivalent series resistance) yenguqu ye-capacitor, ebangela ukunciphisa ukusebenza kunye nokuthembeka.

Ukongeza kwiqondo lokushisa kunye nokuguga, esinye isizathu sokuba i-aluminium electrolytic capacitors ihlala ingaphumeleli kukuchaphazeleka kwabo kwi-voltage surges kunye ne-ripple current. Ezi capacitors zidla ngokusetyenziswa kwiisekethe zobonelelo lwamandla apho zichanabeke kwimisinga ephezulu yeripple kunye ne-voltage spikes. Ngokuhamba kwexesha, ukubonakaliswa ngokuphindaphindiweyo kwimisinga ephezulu kunye ne-voltages kunokubangela ukuba amacandelo angaphakathi e-capacitor ahlambuluke, okubangela ukunciphisa amandla kunye nokwanda kwe-ESR.

Ukongeza, uyilo kunye nomgangatho wei-aluminium electrolytic capacitorskuya kuchaphazela ukuthembeka kwabo kunye nezinga lokungaphumeleli. Ii-capacitors ezitshiphu okanye ezikumgangatho ophantsi zinokusebenzisa izixhobo ezikumgangatho ophantsi kunye neenkqubo zokuvelisa, ezikhokelela kumathuba aphezulu okusilela kwangaphambi kwexesha. Ukusebenzisa umgangatho ophezulu, i-capacitors elinganiswe ngokuchanekileyo kwisixhobo sombane kubalulekile ekunciphiseni umngcipheko wokungaphumeleli.

Ukunciphisa umngcipheko wokungaphumeleli kwe-capacitor, kubalulekile ukuqwalasela iimeko kunye nokusingqongileyo apho i-capacitor iya kusetyenziswa. Ulawulo olufanelekileyo lwe-thermal, ukuchithwa kwe-voltage, kunye nokukhethwa ngokucokisekileyo kwee-capacitors ngokusekelwe kwiinkcukacha zabo kunye nokulinganisa ukuthembeka kunokunceda ukwandisa ubomi babo benkonzo kunye nokunciphisa umngcipheko wokungaphumeleli.

Isishwankathelo, i-aluminium electrolytic capacitors ngumthombo oqhelekileyo wokungaphumeleli kwizixhobo zombane ngenxa yobuntununtunu kubushushu, ukuguga, uxinzelelo lombane, kunye ne-ripple current. Ngokuqonda le miba kunye nokuthatha izilumkiso eziyimfuneko, ezifana nokukhetha ii-capacitors eziphezulu kunye nokuphumeza iimeko ezifanelekileyo zokusebenza, unokunciphisa amathuba okuhluleka kwe-capacitor kwaye uqinisekise ukuthembeka kwezixhobo zakho ze-elektroniki.
