Ma capacitor a mafilimu akhala akugwiritsidwa ntchito kwambiri chifukwa cha makhalidwe awo abwino. Ma capacitor amagwiritsidwa ntchito kwambiri ngati zigawo zazikulu zamagetsi m'mafakitale amagetsi monga zida zapakhomo, ma monitor, zida zowunikira, zinthu zolumikizirana, zida zamagetsi, zida, mita ndi zida zina zamagetsi. Ma capacitor omwe amagwiritsidwa ntchito kwambiri ndi ma capacitor a dielectric a pepala, ma capacitor a ceramic, ma capacitor a electrolytic, ndi zina zotero. Ma capacitor a mafilimu pang'onopang'ono akutenga msika waukulu komanso waukulu chifukwa cha makhalidwe awo abwino, monga kukula kochepa, kulemera kopepuka. Capacitance yokhazikika, kutsekeka kwakukulu kwa insulation, kuyankha pafupipafupi komanso kutayika pang'ono kwa dielectric.

Ma capacitor a filimu amagawidwa m'magulu awiri: mtundu wa laminated ndi mtundu wa wound kutengera njira zosiyanasiyana zogwirira ntchito pakati. Njira yozungulira ya capacitor ya filimu yomwe yayambitsidwa pano makamaka ndi ya ma capacitor wamba ozungulira, mwachitsanzo ma capacitor cores opangidwa ndi chitsulo, filimu yachitsulo, filimu yapulasitiki ndi zipangizo zina (ma capacitor ogwiritsidwa ntchito nthawi zonse, ma capacitor amphamvu kwambiri, ma capacitor otetezeka, ndi zina zotero), zomwe zimagwiritsidwa ntchito kwambiri mu nthawi, kugwedezeka ndi ma filter circuits, ma frequency apamwamba, ma high pulse ndi ma high current, ma screen monitors ndi color TV line reverse circuit, magetsi odutsa mzere wochepetsera phokoso, nthawi zotsutsana ndi kusokoneza, ndi zina zotero.

Kenako, tifotokoza mwatsatanetsatane njira yozungulira. Njira yozungulira ya capacitor imachitika pogwiritsa ntchito filimu yachitsulo yozungulira, zojambulazo zachitsulo ndi filimu yapulasitiki pachimake, ndikuyika ma curve osiyanasiyana ozungulira malinga ndi mphamvu ya capacitor core. Pamene kuchuluka kwa ma curve ozungulira kwafika, zinthuzo zimadulidwa, ndipo pamapeto pake break imatsekedwa kuti amalize kuzunguliza kwa capacitor core. Chithunzi chojambula cha kapangidwe ka zinthucho chikuwonetsedwa mu Chithunzi 1. Chithunzi chojambula cha njira yozungulira chikuwonetsedwa mu Chithunzi 2.

Pali zinthu zambiri zomwe zimakhudza magwiridwe antchito a capacitance panthawi yozungulira, monga kusalala kwa thireyi yopachika zinthu, kusalala kwa pamwamba pa chosinthira chosinthira, kupsinjika kwa zinthu zozungulira, mphamvu ya demetalliazion ya zinthu za filimu, mphamvu yotseka pakusweka, njira yolumikizira zinthu zozungulira, ndi zina zotero. Zonsezi zidzakhudza kwambiri kuyesa magwiridwe antchito a capacitor core yomaliza.

Njira yodziwika bwino yotsekera kumapeto kwa capacitor core ndi kutseka kutentha ndi soldering iron. Potenthetsa nsonga ya chitsulo (kutentha kumadalira njira yopangira zinthu zosiyanasiyana). Pankhani yozungulira pang'onopang'ono pakati, nsonga ya soldering imagwirizana ndi filimu yotsekera yakunja ya capacitor core ndikutsekedwa ndi hot stamping. Ubwino wa seal umakhudza mwachindunji mawonekedwe a pakati.

Filimu ya pulasitiki yomwe ili kumapeto kwa chitseko nthawi zambiri imapezeka m'njira ziwiri: imodzi ndi kuwonjezera wosanjikiza wa filimu ya pulasitiki ku chozungulira, chomwe chimawonjezera makulidwe a wosanjikiza wa capacitor dielectric komanso chimawonjezera kukula kwa pakati pa capacitor. Njira ina ndi kuchotsa chophimba cha filimu yachitsulo kumapeto kwa chozungulira kuti filimu ya pulasitiki yokhala ndi chophimba chachitsulo chochotsedwa, chomwe chingachepetse kukula kwa pakati ndi mphamvu yofanana ndi pakati pa capacitor.
