Zifukwa Zakulephera kwa Zosefera Mafilimu Capacitors

Ma capacitors a filimundi ma capacitor abwino kwambiri chifukwa cha katundu wawo wambiri.Ili ndi kukana kwakukulu kwa insulation, mawonekedwe abwino kwambiri afupipafupi (kuyankha kwafupipafupi), komanso kutayika kwa dielectric.Kutengera zabwino zomwe tafotokozazi, ma capacitor amafilimu amagwiritsidwa ntchito kwambiri m'mabwalo a analogi.Ma capacitor amakanema ali ndi ntchito yosefera, ndiye kusefa ma capacitor amakanema ndi chiyani?
Filter film capacitor ndi mtundu wa chipangizo chosungiramo mphamvu chomwe chimayikidwa kumapeto onse a rectifier circuit kuti muchepetse AC pulsation ripple coefficient ndikuwongolera kutulutsa kosalala kwa DC.Kuzungulira kwa fyuluta kumafuna mphamvu yaikulu ya capacitor yosungirako mphamvu.M'mabwalo onse omwe amafunikira kusintha kusintha kwaposachedwa kukhala kolunjika, kuyika ma capacitor a fyuluta kumapangitsa kuti magwiridwe antchito a dera lamagetsi azikhala okhazikika, komanso kuchepetsa kusokonezedwa kwa ma alternating ripple pamagetsi.Amapezeka kuti fyuluta filimu capacitor amalephera pa ntchito, zomwe mwina chifukwa cha zifukwa izi:

1) Ubwino wa mankhwala a fyuluta filimu capacitor palokha, monga osayenera kupanga njira ndi zipangizo, ndi chizindikiro capacitance sagwirizana ndi capacitance weniweni, ndipo ukalamba chifukwa cha ntchito nthawi yaitali kumayambitsa kupsa mtima.
2) Chikoka cha chilengedwe chakunja, monga kuyika pamalo opanda kutentha kwabwino kapena pafupi ndi gwero la kutentha, kugwirizana kosauka kwa ma capacitors, kukhudzana kosauka, ndi zina zotero, kungayambitsenso kutopa mosavuta.
3) Vuto la Harmonic, ma harmonics amachititsa kuti fyuluta filimu capacitor imveke, kuchititsa kuti capacitor iwonongeke ndikuwotcha.
Palinso zifukwa zina zapadera.M'pofunika kusanthula ndi kuweruza malo amene fyuluta filimu capacitor kuwotchedwa, ndipo pang'onopang'ono kufufuza chifukwa cha kulephera.Nthawi zina zing'onozing'ono zingakhalenso chifukwa cha kutopa.
Posankha capacitor ya filimu, muyenera kupeza wopanga wodalirika.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.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.Takulandirani kuti mutithandize.
