Kuyerekeza Ma Capacitor Amafilimu ndi Electrolytic Capacitors

Ma capacitors a filimu, omwe amadziwikanso kuti pulasitiki film capacitors, amagwiritsa ntchito filimu ya pulasitiki monga dielectric, zitsulo zojambulazo kapena filimu yazitsulo ngati ma electrode.Zida zodziwika bwino za dielectric za ma capacitor a filimu ndi mafilimu a polyester ndi mafilimu a polypropylene.

Electrolytic capacitors ntchito zitsulo zojambulazo monga elekitirodi zabwino, ndi okusayidi filimu amene ali pafupi ndi zitsulo ndi elekitirodi zabwino ndi dielectric, ndi cathode wapangidwa zinthu conductive, electrolyte (electrolyte akhoza kukhala madzi kapena olimba) ndi zipangizo zina.Chifukwa electrolyte ndilo gawo lalikulu la cathode, kotero electrolytic capacitor inatchedwa dzina lake.

Electrolytic capacitors amagawidwa kukhala mizati zabwino ndi zoipa, kotero mizati zabwino ndi zoipa sangathe kusinthidwa poika capacitors electrolytic, apo ayi zidzachititsa dera lalifupi.

Ma capacitor amafilimu ndi ma electrolytic capacitors onse ndi ma capacitors, pali kusiyana kotani pakati pawo?

1. Nthawi ya moyo: Nthawi yogwira ntchito ya electrolytic capacitors ndi yochepa;pamene ma capacitors a filimu amatha kugwira ntchito kwa nthawi yaitali ngati palibe vuto mu khalidwe, lomwe ndi lamphamvu kuposa la electrolytic capacitors.

2. Makhalidwe a kutentha: Kutentha kogwira ntchito kwa ma capacitor a filimu ndi -40 ° C ~ + 105 ° C.Ma capacitor amakanema amakhala ndi kutentha kwabwino ndipo amatha kugwira ntchito bwino m'malo ozizira kapena m'malo otentha achipululu;Chifukwa cha kukhalapo kwa electrolyte.ma electrolytic capacitors amatha kukhazikika pamalo otsika kutentha, kuchepetsa magwiridwe antchito.

3. Makhalidwe afupipafupi: Mphamvu ya electrolytic capacitors imachepa pang'onopang'ono ndi kuwonjezeka kwafupipafupi, ndipo kutaya kumawonjezeka kwambiri;pamene mphamvu ya ma capacitors a filimu imachepa pang'ono, ndipo ma capacitors a filimu sakhala ndi kutaya kwakukulu pamene mafupipafupi akuwonjezeka.Kuchokera pamawonedwe awa owonera mafilimu ma capacitors ali ndi kutayika kochepa komanso mawonekedwe abwino pafupipafupi.

4.Kukhoza kupirira overvoltage: electrolytic capacitors akhoza kupirira overvoltage pafupifupi 20%.Pamene overvoltage ili pamwamba, ma electrolytic capacitors adzawonongeka;ma capacitor amakanema amatha kupirira ma overvoltages apamwamba kuposa 1.5 nthawi yamagetsi ovotera munthawi yochepa.

Kuchokera pazomwe tafotokozazi, machitidwe a ma capacitors a filimu ndi abwino kuposa a electrolytic capacitors.Muzinthu zina, ma capacitor amafilimu ndi abwino kuposa ma electrolytic capacitors.Komabe, kaya ndi ma capacitors a filimu kapena ma electrolytic capacitors, ndikofunikira kusankha ma capacitors okhala ndi mtundu wotsimikizika.

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.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.
