Chifukwa chiyani Ceramic Capacitors "Akugwedeza"

Ndi chitukuko cha sayansi ndi ukadaulo, zinthu zamagetsi zakhala chinthu chofunikira kwambiri pamoyo watsiku ndi tsiku wa anthu.Zogulitsa zamagetsi zili ndi zida zambiri zamagetsi, monga ma capacitor a ceramic.

1. Kodi ceramic capacitor ndi chiyani?

Ceramic capacitor (ceramic condenser) imagwiritsa ntchito ceramic yapamwamba ya dielectric nthawi zonse ngati dielectric, kupoperani siliva wosanjikiza mbali zonse za gawo lapansi la ceramic, ndiyeno filimu ya siliva imawotcha pa kutentha kwakukulu monga electrode, waya wotsogolera ndi welded pa elekitirodi, ndi pamwamba amakutidwa ndi chitetezo enamel kapena yokutidwa ndi epoxy utomoni.Maonekedwe ake nthawi zambiri amakhala ngati pepala, komanso amakhala ndi mawonekedwe a chubu, bwalo ndi mawonekedwe ena.

Ceramic capacitors omwe amagwiritsidwa ntchito pamagetsi ali ndi ubwino wocheperako, mphamvu yopirira kwambiri, komanso ma frequency abwino.Ndi chitukuko ndi kupita patsogolo kwa sayansi ndi ukadaulo, ma capacitor a ceramic akhala chinthu chofunikira kwambiri pamagetsi pazamagetsi.

2. N'chifukwa chiyani ma capacitor a ceramic "amafuula"?

Mukamagwiritsa ntchito zinthu zamagetsi, nthawi zina mumamva phokoso.Ngakhale kuti phokosolo ndi laling’ono, mukhoza kulimva ngati mumvetsera mosamala.mawu awa ndi chiyani?Chifukwa chiyani izi zimamveka mukamagwiritsa ntchito zinthu zamagetsi?

Ndipotu, phokosoli limayambitsidwa ndi ma capacitors a ceramic.Chifukwa cha kuchuluka kwa ma dielectric okhazikika a ceramic capacitors, zinthuzo zimatulutsa kukulitsa ndi kupindika mwamphamvu pansi pa gawo lamagetsi lakunja, lomwe limatchedwa piezoelectric effect.Kuwonjezeka kwachiwawa ndi kutsika kumapangitsa kuti pamwamba pa bolodi la dera ligwedezeke ndi kutulutsa phokoso.Pamene kugwedezeka kwafupipafupi kugwera mkati mwa makutu a anthu (20Hz ~ 20Khz), phokoso lidzapangidwa, lomwe limatchedwa "kulira".

Kaya ndi kompyuta yolembera kapena foni yam'manja, zofunikira zamagetsi zikukwera kwambiri, kotero kuti ma capacitor ambiri a MLCC amalumikizidwa mofanana pamaneti amagetsi, ndipo ndikosavuta kuyimba mluzu ngati kapangidwe kake ndi kolakwika. kapena njira yogwirira ntchito ndi yachilendo.

Zomwe zili pamwambazi ndi chifukwa chake ma capacitors a ceramic "squeak".

Sankhani wopanga wodalirika pogula ma capacitor a ceramic angapewe mavuto ambiri osafunikira.JEC wopanga choyambirira sikuti ali ndi mitundu yonse ya ma capacitor a ceramic omwe ali ndi mtundu wotsimikizika, komanso amaperekanso nkhawa zotsatsa zotsatsa.JEC mafakitale wadutsa ISO9001: 2015 khalidwe kasamalidwe dongosolo chitsimikizo;JEC chitetezo capacitors (X capacitors ndi Y capacitors) ndi varistors adutsa chiphaso cha mayiko osiyanasiyana;Ma capacitor a JEC ceramic, ma capacitor amafilimu ndi ma super capacitors amagwirizana ndi zizindikiro zotsika za kaboni.
