Li-dielectric tsa filimi ea polasetiki tse sebelisoang ka tloaelo ha ho etsoa li-capacitor tse entsoeng ka tšepe li kenyelletsa polypropylene (PP), polyphenylene sulfide (PPS), polyester, le pampiri ea metalized (MP).Lisebelisoa tsena tsa dielectric li na le bokhoni bo fapaneng ba ho iphekola.

Ha ho senyeha ho etsahala ka metallized filimi capacitor, arcing e etsa hore lera le tšesaane la tšepe le pota-potileng sebaka sa phoso le fetohe mouoane.Ts'ebetso ena ea vaporization e tlosa lera la tšepe la conductive sebakeng se potolohileng sekoli.Kaha thepa ea conductive e tlosoa, potoloho e khutšoanyane e ke ke ea etsahala pakeng tsa lipoleiti.Sena se thibela ho hloleha ha karolo.

Bokhoni ba ho ipholisa ba metallized filimi capacitor bo itšetlehile ka lintlha tse ngata tse kenyeletsang thepa ea thepa ea dielectric le botenya ba lera la tšepe.Ts'ebetso ea mouoane e hloka phepelo e lekaneng ea oksijene le lisebelisoa tsa dielectric tse nang le oksijene e holimo holimo li na le thepa e ntle ea ho ipholisa.Tse ling tsa li-dielectric tsa filimi ea polasetiki tse nang le litšobotsi tse ntle tsa ho ipholisa li kenyelletsa polypropylene, polyester le polycarbonate.Ka lehlakoreng le leng, li-dielectric tsa filimi ea polasetiki tse nang le oksijene e tlase ea bokaholimo li na le litšobotsi tse mpe tsa ho ipholisa.Polyphenylene sulfide (PPS) ke e 'ngoe ea lisebelisoa tse joalo tsa dielectric.

Ntle le ho matlafatsa ts'epo, bokhoni ba ho ipholisa ba li-capacitor tse entsoeng ka tšepe li thusa ho ntlafatsa bophelo ba bona ba ts'ebetso.Leha ho le joalo, ho iphekola ho baka ho fokotseha ha sebaka sa electrode ea metallized ka nako.

Lits'ebetsong, a mang a maemo a ka potlakisang ho hloleha ha karolo a kenyelletsa mocheso o phahameng, maqhubu a phahameng, lehalima, mongobo o phahameng, le tšitiso ea motlakase (EMI).

Ntle le thepa e ntle ea ho ipholisa, li-capacitor tsa filimi ea metallized polyester le tsona li na le dielectric tse phahameng kamehla, botsitso bo botle ba mocheso, matla a phahameng a dielectric, le katleho e ntle ea volumetric.Litšobotsi tsena li etsa hore li-capacitor tsena e be tse loketseng bakeng sa ts'ebeliso ea sepheo se akaretsang.Li-capacitor tsa polyester tse entsoeng ka tšepe li sebelisoa haholo bakeng sa lits'ebetso tsa DC joalo ka ho thibela, ho feta, ho theola le ho hatella lerata.

Metallized polypropylene capacitor e fana ka khanyetso e phahameng ea insulation, ho monya ha dielectric tse tlase, tahlehelo e tlase ea dielectric, matla a phahameng a dielectric, le botsitso ba nako e telele.Likarolo tsena tse sebetsang hantle sebakeng li sebelisoa haholo lits'ebetsong tse khomaretsoeng tse kholo joalo ka li-circuits tsa filter, li-ballast tsa mabone le li-circuits tsa snubber.Li-capacitor tse nang le metallized polypropylene film capacitor li ka mamella meroalo e phahameng ea motlakase le meroalo e phahameng ea pulse, 'me li loketse lits'ebetso tse nang le monyetla o moholo oa ho ba le maqhubu a phahameng.Li-capacitor tsena li sebelisoa hangata ho li-motor controller, li-snubbers, lisebelisoa tsa motlakase tsa switch mode le li-monitor.
