Uthotho lwe-DMJ-MC yebhasi ye-DC

Ii-capacitor zefilimu ezenziwe ngesinyithi zenziwe ngeefilimu ezimbini ezenziwe ngesinyithi ezinefilimu yeplastiki njenge-dielectric.

Isinyithi se-aluminium esincinci kakhulu (~ 0.03 μm[2]) esifakwe kwi-vacuum sisetyenziswa kwicala elinye okanye omabini ukuze sisebenze njengee-electrodes.

Ii-capacitors zefilimu yePolypropylene

Ii-capacitor ze-dielectric dc zefilimu ye-polypropylene elungisiweyo,

Olu lwakhiwo lunokuba neempawu "zokuziphilisa", kuba ukuphazamiseka kwe-dielectric okanye ii-short circuits phakathi kwee-electrodes azikhokeleli ekutshatyalalisweni kwecandelo.

Ngolu yilo lusisiseko, kunokwenzeka ukwenza iimveliso ezikumgangatho ophezulu ezifana nee-capacitors "ezingenasiphene" kunye nokuvelisa ii-wound capacitors ezinexabiso elikhulu le-capacitance (ukuya kuthi ga kwi-100 μF nangaphezulu) kwiimeko ezincinci (ukusebenza kakuhle kwe-volumetric) xa kuthelekiswa nokwakhiwa kwefilimu/i-foil.

I-CRE inamandla ngenxa yobuchule bayo bophando nophuhliso, siphuhlisa i-capacitor ngokwe-capacitance elinganisiweyo, i-voltage elinganisiweyo, indawo yokusebenza, njl.

Uphawu

1. Itekhnoloji yohlobo olomileyo;

2. Uluhlu olubanzi lobushushu;

3. Ubuchule bokumelana nee-voltage eziphezulu kakhulu;

4. Ukulahleka kombane okuphantsi;

5. Uyakwazi ukumelana nokunyuka kwamandla aphezulu naphezulu kakhulu.

Isicelo

Ii-capacitor zefilimu ezisetyenziswa kwizixhobo ze-elektroniki zipakishwe ngeendlela eziqhelekileyo neziqhelekileyo zoshishino: i-axial, i-radial, i-cylindrical, i-metal case, njl.
