Umbuzo: I-Ceramic capacitors ichaphazeleka ngokuguga
I-Ceramic capacitors ichaphazeleka yiziganeko zokuguga ezihambelana notshintsho kwi-dielectric crystal structure, ezibonakalisa njengotshintsho kwi-capacitance kunye ne-dissipation factor emva kokudubula kokuqala kwezinto ze-dielectric.Ngokungqinelana neemodeli ezisele zibekiwe, imathiriyeli ye-dielectric yodidi lwe-EIA ichaphazeleka kancinane kwaye ibonwa ngokubanzi njengengagugi, ngelixa imathiriyeli ye-dielectric yodidi lwe-EIA yodidi II ichaphazeleka ngokuphakathi kwaye imathiriyeli ye-EIA yoHlelo lwe-III ithande ukuchaphazeleka kakhulu.Le nkqubo yokuguga inokuthi ihlaziywe (okanye isixhobo "de-aging") ngokuvezwa kumaqondo obushushu ngaphezu kweqondo lokushisa le-dielectric's Curie ixesha elide ngokwaneleyo ukuvumela ukuba isakhiwo sekristale siphinde senze;iqondo lobushushu liphezulu, lifutshane ixesha elifunekayo.Kuba iqondo lobushushu leCurie yee-dielectrics ezininzi ze-ceramic lisezantsi kunelo lifunyenwe kwiinkqubo ezininzi zokuthengisela, kusenokwenzeka ukuba isixhobo siya kuba mdala ngokuyinxenye ngexesha lokudityaniswa.
Oku kuziphatha kokuguga kwecandelo kudla ngokubonakaliswa njengepesenti yokutshintsha kwamandla kwishumi leminyaka leeyure, ngokumalunga nomthamo olinganiswe "kwiqondo lokugqibela lokufudumeza," ixesha lokugqibela icandelo lifudunyezwe ngaphezu kobushushu beCurie ixesha elide ngokwaneleyo ukuba litshintshe ngokupheleleyo ikristale. isakhiwo.Ngamanye amazwi, i-capacitor enezinga lokuguga elingu- (-) 5%, elilinganiselwa kwi-100uF kwimo “ye-oveni entsha”, kulindeleke ukuba ilinganise malunga ne-95,90 kunye ne-85uF emva kwe-1, 10 kunye ne-100 yeeyure zokuphuma kwi-oveni. , ngokulandelelanayo.
Ngokucacileyo, oku kuphakamisa umbuzo wento yokuba i-capacitance yecandelo kufuneka ibe yintoni, kwaye ukuba loo mali isoloko iguquka, inxalenye iya kusetyenziswa kwi-shelf nangona ingasetyenziswanga kwi-package yayo yokuqala.Imigangatho yoshishino ye-EIA-521 kunye ne-IEC-384-9 ilungisa lo mbandela, ngokusisiseko ichaza ukuba icandelo kufuneka lifikelele kwixabiso elichaziweyo lokunyamezela iiyure ze-1000 (malunga neentsuku ezingama-42) emva kokufudumeza kokugqibela.Amanqaku alandelayo eminyaka elishumi (iiyure ezili-10K kunye ne-100K) aguqulela kumnyaka ongaphezulu kancinane ko-1 kunye nangaphezulu kweminyaka eli-11 ngokulandelelanayo.Ukuqhubela phambili ukunyanzela izinto, inkqubo yokuguga iyenzeka kwiqondo elixhomekeke kwiqondo lokushisa;ukuya kuthi ga kwiqondo lobushushu leCurie le-dielectric, ukonyuka kobushushu besixhobo ngokuqhelekileyo kukhawulezisa inkqubo yokuguga.
Ekubeni iziganeko zokuguga zingabangela ukuba izixhobo zivele ngaphandle kokunyamezela kwazo okuchaziweyo, abaqulunqi beemveliso kunye nabavavanyi bemveliso kufuneka baqaphele le nyaniso;Uvavanyo lwamacandelo asandul 'ukuphuma kwakhona kufuneka alindele amaxabiso aphezulu kancinane, kwaye uyilo kufuneka lube nomda owaneleyo ukulungiselela ukusebenza okuqhelekileyo kwesixhobo njengoko sikhula.Iisekethe zokuguqulwa kwamandla ngumzekelo omhle apho esi siphumo sinokubeka ingozi enkulu, njengoko i-ceramic capacitors idla ngokuchaphazela kakhulu iilophu zolawulo zeesekethe ezinjalo, mhlawumbi njengamacandelo enethiwekhi yembuyekezo okanye njengezinto zokucoca.Iinkqubo ezibonakala zizinzile phantsi kweempembelelo zokuguga kwe-capacitor ngexesha lendibano zingaba zizinzile ngokuhamba kwexesha, njengoko ukulahlekelwa kwekhono ngenxa yokuguga kuchaphazela amandla e-loop yokulawula.Okona kubaluleke kakhulu, ukuba amaxabiso azinzileyo e-capacitance ekuhambeni kwexesha abalulekile, kuphephe ukusebenzisa ii-capacitors ezibonakala zikhulile.
I-Zhejiang NeoDen Technology Co., LTD., Yasekwa ngo-2010, sikwimeko entle ukuba singakuboneleli kuphela umatshini we-pnp okumgangatho ophezulu, kodwa kunye nenkonzo ebalaseleyo emva kwenkonzo yokuthengisa.Iinjineli eziqeqeshwe kakuhle ziya kukunika nayiphi na inkxaso yobugcisa.
Iinjineli ezili-10 ezinamandla kwiqela lenkonzo emva kokuthengisa zinokuphendula imibuzo yabathengi kunye nemibuzo kwiiyure ezisi-8.
Izisombululo zobungcali zinokunikezelwa kwiiyure ezingama-24 zombini imini yokusebenza kunye neeholide.
