I-Frequency Characters of Ceramic Capacitors

I-Ceramic capacitorsyigama elijwayelekile lama-capacitor anezinto zobumba njenge-dielectric.Kunezinhlobonhlobo eziningi, futhi ubukhulu buhluka kakhulu.Ngokusebenzisa i-voltage ye-ceramic capacitors, ingahlukaniswa ngama-voltage aphezulu, i-medium voltage kanye ne-low voltage capacitors ceramic.Ngokusho kwe-coefficient yokushisa, i-dielectric constant ingahlukaniswa ibe yi-coefficient yokushisa engalungile, i-coefficient yokushisa enhle, i-coefficient yokushisa engu-zero, i-dielectric constant constant, i-dielectric constant ephansi njalonjalo.Ngaphezu kwalokho, kunezindlela zokuhlukanisa zohlobo I, uhlobo II, kanye nohlobo III.

Uma kuqhathaniswa namanye ama-capacitor, ama-capacitor e-ceramic ajwayelekile anezinzuzo zokushisa okuphezulu okusebenzayo, i-capacitance enkulu ethize, ukumelana nomswakama omuhle, ukulahlekelwa okuncane kwe-dielectric, kanye ne-coefficient yokushisa ye-capacitance ingakhethwa ebangeni elibanzi.Lesi sihloko sizokhuluma ngezici zemvamisa yama-capacitors e-ceramic athandwayo.

I-Frequency Characters of Ceramic Capacitors
Isici sokuvama kwama-capacitor e-ceramic sibhekisela ebudlelwaneni phakathi kwe-capacitance namanye amapharamitha we-capacitor ene-frequency.Ngokuvamile, lapho i-capacitor isebenza ngemvamisa ephezulu, ngokunyuka kwemvamisa yokusebenza, ngenxa yokuncipha kwe-coefficient ye-dielectric ye-insulating medium, i-capacitance izokwehla, kuyilapho ukulahlekelwa kuzokwanda futhi kuthinte imingcele ye-capacitor.

Ukuze kuqinisekiswe ukuzinza kwama-capacitor e-ceramic, imvamisa yokusebenza ye-capacitor kufanele ngokuvamile ikhethwe ku-1 / 3-1 / 2 yemvamisa yemvelo ye-resonant ye-capacitor.Amandla kanye nemvamisa akuhlukaniseki, futhi ubudlelwano busondelene kakhulu.Ama-capacitor e-ceramic anamandla amakhulu ane-capacitance enkulu anempendulo engalungile kumafrikhwensi aphezulu kodwa asabela kahle kumaza aphansi.Ngakolunye uhlangothi, ama-capacitor e-ceramic anesayizi encane kanye ne-capacitance anempendulo engalungile ekuvaleni okuphansi kanye nokuphendula okuhle kumafrikhwensi aphezulu.

Ngemva kokufunda okuqukethwe okungenhla, ungase ube nokuqonda okuthile ngezici zemvamisa yama-capacitor e-ceramic.Ulwazi olwengeziwe lwe-ceramic capacitor lungatholakala kuwebhusayithi yethu esemthethweni.I-JYH HSU(JEC) Electronics Ltd(noma i-Dongguan Zhixu Electronic Co., Ltd.) inohlu olugcwele lwamamodeli e-varistor nama-capacitor anekhwalithi eqinisekisiwe.I-JEC iphumelele isitifiketi se-ISO9001:2015 yokuphathwa kwekhwalithi;Ama-capacitor okuphepha e-JEC (ama-X capacitor nama-Y capacitor) kanye nama-varistors aphumelele izitifiketi zikazwelonke zamandla amakhulu ezimboni emhlabeni wonke;Ama-ceramic capacitor e-JEC, ama-filimi capacitor nama-super capacitor ahambisana nezinkomba zokuvikela imvelo.
