Isendlalelo sangaphandle sokuvala sama-capacitor e-ceramic anamandla kagesi aphezulu, ikakhulukazi ungqimba lwe-epoxy, alusebenzi nje njengento ehlanganisayo kodwa luphinde lube nomthelela omkhulu kukhwalithi nezici ze-capacitor ngokwayo.
Okokuqala nokubaluleke kakhulu, ukuhlangana phakathi kwama-chips e-ceramic kanye nongqimba lwe-epoxy kuyiphuzu elibalulekile lokuhlangana. Ukubambisana okubuthakathaka kungaholela ekunciphiseni amandla. Ngakho-ke, ukuminyana kwalawa masayithi okubopha kuthinta ngokuqondile ubuqotho besendlalelo se-epoxy, ngokuhlanganisa okuminyene okuholela enanini elincane lokukhishwa okuyingxenye.
Okwesibili, ngesikhathi sokusebenza kwama-capacitor e-ceramic ngaphansi kwezimo eziphezulu ze-voltage noma zokukhishwa, ukucindezeleka okubangelwa ukushisa kwenzeka. Lokhu kucindezela okuphindaphindiwe kokushisa kubangela ukungezwani nokufinyela phakathi kwezingxenye eziyinhloko, okuholela ekuncipheni kwe-resin. Umthamo wokuchithwa kwegesi ngaphakathi kwe-capacitor uyancipha kakhulu, kuyilapho ukucindezeleka kungqimba lwe-epoxy kukhula kakhulu, okwenza i-capacitor ingakwazi ukwehluleka.
Ngaphezu kwalokho, kuvame ukuvunywa ukuthi ngemva kwenqubo ye-sintering emazingeni okushisa aphezulu, ama-capacitor adinga isikhathi sokubuyisela ukuze anciphise ukucindezeleka okushisayo ngezinqubo zemvelo. Uma isikhathi sokululama siside, kulapho amandla ama-capacitor akwazi ukumelana nokushuba, okuqinisekisa ikhwalithi ephezulu. Isibonelo, uma kuqhathaniswa ama-capacitor asanda kukhiqizwa nalawo asethole cishe izinyanga ezimbili zokululama, lawa kamuva akhombisa ukubekezelela amandla kagesi aphezulu, afinyelela amazinga angu-80kV noma ngaphezulu ngisho nalapho evivinywe ku-60kV ekuqaleni.
Ngaphezu kwalokho, ukukhethwa kwezinto ze-epoxy kungaba nomthelela ekusebenzeni kwama-capacitor emazingeni okushisa ahlukene. Amanye ama-ceramic capacitor ane-voltage ephezulu angase ahlangabezane nokusebenza okuncishisiwe emazingeni okushisa aphansi. Isibonelo, uma ingaphansi kwamazinga okushisa aqandayo afinyelela ku--30 degrees Celsius, ukuqhekeka kungase kwakheke ngenxa yezakhiwo ezingezinhle ze-epoxy kumazinga okushisa aphansi anjalo noma ukungahambisani nokunwetshwa nokufinyela kwama-chips e-ceramic. Ngenxa yalokho, ukucindezeleka okungaguquki okubangelwa ukubanda okudlulele kwehluleka ukunciphisa ivolumu ngezinga elifanayo, okuholela ekucindezelekeni kwesakhiwo.
Ngokubhekana nalezi zici kanye nokuqinisekisa ikhwalithi yongqimba lwe-epoxy, abakhiqizi bangathuthukisa ukusebenza okuphelele nokuthembeka kwama-capacitor aphezulu.
