Ceramic Capacitor Application: Non-Wire Phone Charger

Ndi kutuluka kwa mafoni a 5G, chojambulira chasinthanso kukhala kalembedwe katsopano.Pali mtundu watsopano wa charger, womwe sufuna chingwe cholipiritsa kuti upereke foni yam'manja.Foni yam'manja imatha kulipiritsa pokhapokha poyiyika pa mbale yozungulira, ndipo kuthamanga kwachangu kumathamanga kwambiri.Iyi ndi charger yopanda zingwe, ndiye kodi charger yopanda zingwe iyi ndiyosavuta kugwiritsa ntchito?

Kulipiritsa opanda zingwe kumagwiritsidwa ntchito polipiritsa zinthu zamagetsi monga mafoni am'manja.Pachimake cha kulipiritsa kwake ndi ukadaulo wopanda zingwe.Pali mitundu iwiri ya njira zolipirira opanda zingwe: ma elekitirodi induction induction charger ndi resonant charger.

Electromagnetic induction charger nthawi zambiri amagwiritsidwa ntchito pazinthu zamagetsi zotsika mphamvu, monga mafoni am'manja pomwe ma resonant charger amagwiritsidwa ntchito pamagetsi amphamvu kwambiri.Mwachitsanzo, magalimoto ambiri amagetsi amagwiritsa ntchito ma resonant charger.

Popeza mphamvu imaperekedwa pakati pa chojambulira ndi chipangizo chamagetsi kudzera mu mphamvu ya maginito, ndipo palibe mawaya omwe amalumikizidwa kuti apereke mphamvu pakati pa ziwirizi, chojambulira ndi chipangizo chamagetsi sichiyenera kugwirizanitsidwa ndi mawaya.Chigawo chomwe chili mkati mwa charger yopanda zingwe ndichofunika kwambiri kuti muzindikire kuyitanitsa opanda zingwe: NP0 capacitor.

NP0 capacitor ndi mtundu waceramic capacitor, yomwe ndi ya class I ceramic capacitor.Lili ndi makhalidwe obwezera kutentha, kuchepa kwa dielectric ndi kukhazikika kwa kutentha kwakukulu.Kutentha kwake kogwira ntchito ndi -55 ℃～+125 ℃.M'malo awa, kusintha kwa capacitance kwa NPO capacitor kumakhala kochepa, kotero kumatchedwa kutentha kwa chiwongoladzanja.Ndizoyenera ma oscillator, ma resonant, ma frequency okwera kwambiri, ndi mabwalo ena omwe amafunikira kutayika kochepa komanso kukhazikika kokhazikika, kapena kubwezera kutentha.

NP0 capacitor imalumikizidwa motsatizana ndi koyilo yopatsira mkati mwa charger yopanda zingwe kuti ifanane ndi koyilo ya transmitter kuti ipange gawo lamagetsi lamagetsi lomwe lingavomerezedwe ndi wolandila.

NP0 capacitor ndi yaying'ono kukula kwake ndipo sichitenga malo, ndipo ndi yoyenera kugwiritsidwa ntchito pazinthu zomwe zili ndi zofunikira za voliyumu monga kulipira opanda zingwe.Makhalidwe a kuchepa kwa dielectric, kukhazikika kwa kutentha, kugwira ntchito bwino kumatha kupititsa patsogolo kuyitanitsa opanda zingwe, kuchepetsa kutayika kwa mphamvu ndi kuyitanitsa opanda zingwe ndi kutentha.

Ndi kuyitanitsa opanda zingwe, ndikosavuta kwambiri kulipiritsa foni yamakono.Simufunikanso kuwononga nthawi kufunafuna chingwe cholipirira kuti mutseke foni yam'manja.Mutha kulipira foni yam'manja mwachindunji pa charger yopanda zingwe.

Sankhani wopanga wodalirika pogula ma capacitor a ceramic angapewe mavuto ambiri osafunikira.JYH HSU (kapena Dongguan Zhixu Electronics) sikuti ili ndi mitundu yonse ya ma capacitor a ceramic okhala ndi mtundu wotsimikizika, komanso imaperekanso kutsatsa kopanda nkhawa.Ngati mukuyang'ana zida zamagetsi, talandiridwa kuti mutilankhule.
