Korontada SMD

Sharaxaad Gaaban:

Dusha sare ee korontada inductors ee codsiyada u dhexeeya sahayda korontadu ilaa kuwa wax bedelaya. Noocyada asaasiga ah waxaa ka mid ah ferrite iyo budada birta la riixay oo leh topologies ay ka mid yihiin: kuwa aan gaashaanka lahayn, gaashaanka, budada birta ee la cadaadiyo, ferrite dahaarka leh, iyo inductors chipbound.
Iyada oo xudunta luminta hoose iyo cabbirka is haysta, waxay ku habboon tahay xakamaynta buuqa, shaandhada EMI, Si fiican ugu habboon beddelidda maamulayaasha.

Faahfaahinta Alaabta

Tags Product

Baakadaha cajalad & gariirada, aad bay ammaan u tahay in la ilaaliyo alaabta.
Moodeelkan korka-korka korantada ee aan gabbaadka lahayn ayaa bixiya waxqabad la xaqiijiyay oo qiimo weyn leh. bixiyaan qiimaynta saturation sare ee hadda, kaydinta tamarta sare, iyo iska caabin hoose.

Qalabka farsamada ayaa si madaxbanaan u horumariyay oo ay naqshadaysay Mingda.
Waxaan isticmaalnaa alaab birlab ah oo summada gudaha ah iyo fiilooyinka naxaasta ah ee dibadda laga keeno.
16 hababka, lakabka kormeerka tayada lakabka

Guud ahaan, inductance ee inductors silig dhaawaca inductors ee wareegyada elektarooniga ah waa gariiradda hawada-core, ama gariiradda leh xudunta magnetic, kaas oo kaliya ka gudbi kara hadda yar oo adkeysan kara danab hoose; iyo inductors koronto waxay sidoo kale leeyihiin gariiradaha hawada-core iyo magnetic cores, inta badan Dabeecadda ayaa ah in ay ku dhaawacantay fiilooyinka qaro weyn, kuwaas oo u adkeysan kara tobanaan amps, boqolaal, kumanaan, ama xitaa tobanaan kun oo amps. Waxaa jira laba nooc oo ah inductors chip koronto: oo leh dabool birlab ah oo aan lahayn dabool birlab ah, oo inta badan ka kooban xudunta magnetic iyo silig naxaas ah. Waxay inta badan ka ciyaartaa doorka shaandhaynta iyo gariirka wareegga

Ming Da waxay ku siinaysaa cabbirka aad rabto, tayada sida ugu fiican ee aad u isticmaali karto, qiimaha intaad awoodid!

Faa'iidooyinka:

1. Isticmaalka baakadaha cajalad qaadaha ee SMT

2. Hadda la qiimeeyay sare, DCR hoose.

3. Ku haboon dib-u-qulqulka SMT Craft alxanka.

4. U dhis u hoggaansanaanta RoHS oo horseed bilaash ah

5. Qalabka asaasiga ah ee saturation sare iyo cabbir yar

6. Xuddunta ferrite-khasaare-hoose

7. Raadka heerka warshadaha

8. Cabbirka 1068/3316/3340/5022 ayaa kuu diyaar ah.

Waxaan isticmaalnaa cajalad qaade iyo gariirad, taas oo ku habboon SMT ee xoogga wejiga ugu fiican iyo alxanka wanaagsan. Qaab dhismeedkan gaashaanka, qiimaha Q sare. Diidashada birlabeed yar, caabbinta hadda jirta, iska caabin yar oo DC ah.
