Muri iki cyumweru, tuzagira intangiriro ku ikoranabuhanga ryo gufunga ibyuma rya capacitor ya filime. Iyi nkuru igaragaza inzira zijyanye n'ibikoresho byo gufunga ibyuma bya capacitor ya filime, kandi itanga ibisobanuro birambuye ku ikoranabuhanga ry'ingenzi rikoreshwa, nko gukoresha ikoranabuhanga ryo kugenzura umuvuduko w'amashanyarazi, ikoranabuhanga ryo kugenzura imizunguruko, ikoranabuhanga ryo gukuraho ibyuma, n'ikoranabuhanga ryo kuziba ubushyuhe.

Capacitors za firime zagiye zikoreshwa cyane kubera imiterere yazo myiza. Capacitors zikoreshwa cyane nk'ibice by'ibanze bya electronic mu nganda z'ikoranabuhanga nk'ibikoresho byo mu rugo, monitors, ibikoresho by'amatara, ibikoresho by'itumanaho, ibikoresho by'amashanyarazi, ibikoresho, ibyuma n'ibindi bikoresho by'ikoranabuhanga. Capacitors zikoreshwa cyane ni capacitors za dielectric zo mu mpapuro, capacitors za ceramic, capacitors za electrolytic, nibindi. Capacitors za firime zigenda zifata isoko rinini buhoro buhoro kubera imiterere yazo myiza, nko kuba nto, uburemere bworoshye. Capacitance ihamye, impedance nyinshi yo gushyushya, igisubizo cyagutse n'igihombo gito cya dielectric.

Capacitors za filime zigabanyijemo ibice bibiri: ubwoko bwa laminated n'ubwoko bw'igisebe hakurikijwe uburyo butandukanye bwo gutunganya core. Uburyo bwo gufunga capacitors za filime bwatangiwe hano ahanini ni ubwo gufunga capacitors zisanzwe, urugero nk'imirongo ya capacitors ikozwe mu byuma, filime y'icyuma, filime ya pulasitiki n'ibindi bikoresho (capacitors rusange, capacitors za voltage nyinshi, capacitors z'umutekano, nibindi), bikoreshwa cyane mu gupima igihe, guhindagurika no kuyungurura, inshuro nyinshi, pulse nyinshi n'igihe kinini cy'umuvuduko w'amashanyarazi, ecran monitors na color TV line reverse circuit, power supply cross-line nought reduction circuit, anti-interference occasions, nibindi.

Hanyuma, tuzagaragaza uburyo bwo kuzunguruka mu buryo burambuye. Tekiniki zo kuzunguruka kwa capacitor zikorwa hakoreshejwe firime y'icyuma izunguruka, foil y'icyuma na firime ya pulasitiki ku gice cy'imbere, hanyuma tugashyiraho imizunguruko itandukanye izunguruka hakurikijwe ubushobozi bwa ferime. Iyo umubare w'imizunguruko izunguruka ugeze, ibikoresho biracibwa, hanyuma imvune irafungwa kugira ngo firime y'inkingi ya capacitor irangire. Ishusho y'imiterere y'ibikoresho igaragara ku Ishusho ya 1. Ishusho y'imizunguruko y'imizunguruko igaragara ku Ishusho ya 2.

Hari ibintu byinshi bigira ingaruka ku mikorere ya capacitance mu gihe cyo kuzunguruka, nko kuba isahani imanitseho ibikoresho, uburyo ubuso bw'umuzingo uhindura ibintu, imbaraga z'ibikoresho bizunguruka, ingaruka z'ibikoresho bizunguruka ku gukuraho icyuma, ingaruka zo gufunga mu gihe cyo kuruhuka, uburyo ibikoresho bizunguruka bishyirwa hamwe, nibindi. Ibi byose bizagira ingaruka zikomeye ku igeragezwa ry'imikorere y'inkingi ya nyuma ya capacitor.

Uburyo busanzwe bwo gufunga impera y'inyuma y'umutwe wa capacitor ni ugufunga ubushyuhe ukoresheje icyuma gishongesha. Gushyushya umutwe w'icyuma (ubushyuhe buterwa n'uburyo ibintu bitandukanye bikorwa). Mu gihe igice cy'inyuma kizunguruka vuba, umutwe w'icyuma gishongesha uhuzwa n'icyuma gishongesha inyuma y'umutwe wa capacitor hanyuma kigafungwa hakoreshejwe uburyo bushyushye bwo gufunga. Ubwiza bw'icyuma bigira ingaruka zitaziguye ku kuntu igice cy'inyuma kigaragara.

Ifiriti ya pulasitiki iri ku mpera yo gufunga ikunze kuboneka mu buryo bubiri: bumwe ni ugushyiramo urwego rwa firiti ya pulasitiki ku ruziga, ibyo byongera ubugari bw'urwego rwa capacitor dielectric ndetse bikongera uburebure bw'umutwe wa capacitor. Ubundi buryo ni ugukuraho icyuma gitwikiriye ku mpera y'uruziga kugira ngo firiti ya pulasitiki ikuweho icyuma gitwikiriye, ibyo bikaba bishobora kugabanya uburebure bw'umutwe hamwe n'ubushobozi bumwe n'umutwe wa capacitor.
