DC bhazi capacitor DMJ-MC akatevedzana

Metallized film capacitors inogadzirwa nemafirimu maviri ane simbi ane firimu repurasitiki se dielectric.

Iyo yakatetepa kwazvo (~ 0.03 μm[2]) vacuum-yakaiswa aruminiyamu metallization inoiswa kune rimwe kana mativi ese kuti ashande semagetsi.

Polypropylene film capacitors

Yakagadziriswa metallized polypropylene firimu dielectric dc capacitors,

Ichi chigadziro chinogona kuva ne "self-healing" maitiro, mukuti dielectric breakdowns kana mapfupi mafupi pakati pe electrodes hazvirevi kutungamirira kuparadzwa kwechikamu.

Neichi dhizaini yakakosha, zvinokwanisika kugadzira zvigadzirwa zvemhando yepamusoro senge "zero defect" capacitors uye kugadzira maronda capacitor ane hombe capacitance values (kusvika ku100 μF uye yakakura) mumakesi madiki (yakakwira volumetric kunyatsoshanda) zvichienzaniswa nefirimu/ kuvakwa kwefoiri.

CRE yakasimba kune yayo R&D kugona, isu tinogadzira capacitor zvinoenderana neyakayerwa capacitance, yakayerwa voltage, nharaunda yekushanda, nezvimwe.

Feature

1. Dry-type teknolojia;

2. Wide tembiricha range;

3. Kukwanisa kushingirira kukwira zvakanyanya;

4. Kurasikirwa kwemagetsi kwakaderera;

5. Inokwanisa kubata yakakwirira uye yakanyanya kukwira ikozvino.

Application

Mafirimu capacitor ekushandisa mumidziyo yemagetsi akaiswa mune akajairwa uye akajairwa indasitiri masitayipi: axial, radial, cylindrical, simbi kesi, nezvimwe.
