Indlela I-Voltage Ethinta Ngayo Umthamo Wama-Ceramic Capacitors

I-Ceramic capacitorsasetshenziswa kabanzi emishinini yezempi ye-elekthronikhi, imishini yokuxhumana yesistimu, okokusebenza kokulawula izimboni, ugesi wezimoto, imikhiqizo ye-elekthronikhi yabathengi, njll.

Ukumelana okuphansi kwangaphakathi kwama-capacitor e-ceramic kusiza kakhulu ekuphumeni okuphansi kwe-ripple futhi kungacindezela umsindo we-high-frequency, kodwa amandla ama-ceramic capacitor anciphisa amandla kagesi aphezulu.Kungani?

Ukubola kwe-capacitance ye-ceramic capacitors ku-voltage ephezulu kuhlobene nezakhiwo zezinto ezisetshenziswa kuma-ceramic capacitors.

Wonke ama-capacitor akhiwe ngama-conductor amabili, ahlanganiswe komunye nomunye.Uma i-voltage isetshenziswa phakathi kwama-conductor amabili, kwakhiwa inkambu kagesi phakathi kwama-conductor amabili.Ngaphansi kwesenzo senkambu kagesi, amashaji e-dielectric phakathi kwama-conductor azobuthana ekuqondeni kwabaqhubi ababili.Inkambu kagesi eyenziwe yibo iphambene nensimu kagesi yasekuqaleni, futhi inkambu kagesi ngaphakathi kwe-dielectric iba buthakathaka.Isilinganiso senkambu kagesi esetshenzisiwe yasekuqaleni namandla enkambu kagesi ku-dielectric yimvume ehlobene ye-dielectric.

Izinto ezisetshenziswa ku-ceramic capacitor iyi-ceramic ene-dielectric engaguquki, ingxenye eyinhloko yi-barium titanate, i-dielectric engaguquki imayelana ne-5000, kanti i-dielectric constant iphakeme kakhulu.

Njengoba i-dielectric inganciphisa amandla enkambu kagesi, akulula ukudilizwa, ngakho-ke ikhono le-capacitor ukugcina ukushaja kagesi lingathuthukiswa, okungukuthi, i-capacitance ithuthukisiwe.Kodwa-ke, ngaphansi kwe-voltage ephezulu, amandla kagesi ku-dielectric azoqhubeka nokukhula, futhi i-dielectric constant izokwehla kancane kancane, yingakho amandla e-ceramic capacitors ebola ngaphansi kwe-voltage ephezulu.

Khetha umkhiqizi onokwethenjelwa lapho uthenga ama-capacitor e-ceramic angagwema izinkinga eziningi ezingadingekile.Umkhiqizi wangempela we-JEC akanawo amamodeli agcwele ama-capacitor e-ceramic anekhwalithi eqinisekisiwe, kodwa futhi unikeza ngaphandle kokukhathazeka ngemva kokuthengisa.Amafekthri e-JEC aphumelele i-ISO9001: isitifiketi sohlelo lokuphathwa kwekhwalithi ka-2015;Ama-capacitor okuphepha e-JEC (ama-X capacitors kanye nama-Y capacitors) kanye nama-varistors aphumelele isitifiketi samazwe ahlukahlukene;Ama-ceramic capacitor e-JEC, ama-filimi capacitor nama-super capacitor ahambisana nezinkomba zekhabhoni ephansi.
