Metalized film capacitor for power supply application (DMJ-MC)

Kufotokozera Kwachidule:

Mphamvu zamagetsi zamagetsi capacitors DMJ-MC mndandanda

Polypropylene film capacitors amatha kukhala oyenerera kugwiritsa ntchito kalasi yapamwamba.

1. Zinthu zotsika kwambiri zotayira (tani δ)

2. zinthu zapamwamba (Q)

3. mitengo yotsika kwambiri (ESL)

4. Palibe maikolofoni poyerekeza ndi ma capacitors a ceramic

5. Kumanga kwazitsulo kumakhala ndi zinthu zodzichiritsa zokha

6. Ma voltages okwera kwambiri

7. High ripple panopa kupirira

Mphamvu zathu

1. Utumiki wokonzekera mwamakonda malinga ndi ntchito yeniyeni;

2. CRE adakumana ndi gulu laukadaulo kuti athandizire makasitomala athu ndi yankho laukadaulo kwambiri;

3. maola 24 pa intaneti ntchito;

4. Deta, zojambula, ntchito zopambana zilipo.

Mbali

Kukula kwakugwiritsa ntchito kwa ma capacitor a DC ndikosiyananso.Ma capacitor osalala amagwiritsidwa ntchito kuchepetsa gawo la AC lamagetsi osinthasintha a DC (monga magetsi opangira mafakitale).

Ma capacitor athu amakanema amatha kuyamwa ndikutulutsa mafunde okwera kwambiri pakanthawi kochepa, nsonga zapamwamba za mafunde zimakhala zazikulu kwambiri kuposa ma RMS.

Ma surge (pulse) discharge capacitor amathanso kupereka kapena kuyamwa kwanthawi yayitali.Nthawi zambiri amagwiritsidwa ntchito potulutsa ma voliyumu osabweza, komanso pama frequency otsika, monga muukadaulo wa laser.

Kugwiritsa ntchito

1. Zida zoyezera magetsi apamwamba;
2. DC olamulira;
3. Tekinoloje yoyezera ndi kuwongolera;
4. Kusungirako mphamvu m'mabwalo apakati a DC;
5. transistor ndi thyristor mphamvu converters;
