Ubungakanani kunye nemilinganiselo:

Iimpawu zombane:

Usetyenziso:

1. Ukutshintsha izilawuli ezinombane ophantsi wokusebenza (amakhadi egraphic, iiPC-Cards ezifakwe ngaphakathi, iibhodi ezinkulu)

2.I-Integrated DC/DC converter

3.Ukukhanyisa i-LED, izixhobo zonxibelelwano eziphathwayo,

4. Ukubeka iliso, ikhamera ephathekayo, iTelecommunication, iimveliso zedijithali

Indlela yokukhetha i-inductor yetshiphu echanekileyo yokulungiswa kwetshiphu ye-SMT?

1. Ububanzi obupheleleyo be-chip inductor kufuneka bube buphantsi kunobubanzi obupheleleyo be-inductor ukuphepha izinto ezithengiswayo ezigqithisileyo ekubangeleni uxinzelelo olugqithisileyo lokutshintsha ixabiso le-inductor xa amanzi epholile.

2. Ukuchaneka kwee-chip inductors ezifumanekayo kwimarike yokuthengisa ubukhulu becala ±10%. Ukuba ukuchaneka kungaphezulu kwe-±5%, kufuneka u-odole kwangoko.

3. Ezinye ii-chip inductors zinokudityaniswa nge-oven yokuqukuqela kunye ne-wave soldering, kodwa kukwakho ezinye ii-inductors ze-chip ezingenako ukudityaniswa ngokuthengiswa kwamaza.

4. Xa kulungiswa, akunakwenzeka ukutshintsha i-inductor kunye ne-chip inductor kuphela ngenani le-inductor. Ukuze kuqinisekiswe iimpawu zokusebenza, kuyafuneka ukuba uqonde uluhlu lwe-frequency yokusebenza kwe-chip inductors.

5. Uyilo lwembonakalo kunye nesiseko esicacileyo se-chip inductors ziyafana, kwaye imbonakalo yoyilo ayinalo uphawu olubalulekileyo. Xa i-soldering ngesandla okanye iipatches ezenziwe ngesandla, kufuneka uqaphele kakhulu kwaye ungenzi iimpazamo okanye uthabathe iindawo ezingalunganga.

6. Kweli nqanaba, kukho ezintathu eziqhelekileyo ze-chip inductors: uhlobo lokuqala, i-high-frequency inductors yokufudumeza i-microwave. Isebenza kwiinkqubo zoluhlu lwamaxesha malunga ne-1GHz. Uhlobo lwesibini luyi-high-frequency chip inductors. Ilungele uchungechunge lwesekethe yolawulo lwe-resonance kunye nesekethe yonikezelo lwamandla ekhethiweyo. Uhlobo lwesithathu luyi-inductors esebenzayo. Ngokuqhelekileyo kusebenza kwiisekethe zamandla zamashumi e-megahertz.

7. Iimveliso ezahlukeneyo zisebenzisa i-diameters ezahlukeneyo zeekhoyili zamagnetic. Nangona umlinganiselo ofanayo we-inductor usetyenziswa, umlinganiselo wokuchasa obonakalisiweyo awufani. Kwi-loop yokulawula i-high-frequency, ukulinganisa ukuchasana kuyingozi kakhulu kwixabiso le-Q, ngoko ke yithathele ingqalelo xa uyila iskimu.

8. Kuvunyelwe ukuba ibe yixabiso lesalathisi se-chip inductance ngokwexabiso elikhulu langoku. Xa umbane wesiphaluka kufuneka ube noxanduva lobuninzi bangoku, eli xabiso lesalathisi se-capacitor kufuneka lithathelwe ingqalelo.

9. Xa ii-inductors zamandla zisetyenziswa kwii-converter ze-DC/DC, ubukhulu bee-inductors zabo bubeka ingozi ngokukhawuleza isimo sengqondo sokusebenza sesekethe yamandla. Ngokwemeko yangempela, indlela yokulungelelanisa ikhoyili yamagnetic ingasetyenziselwa ukutshintsha i-inductors ukufezekisa iziphumo eziphathekayo.

10. I-inductors ye-wire-inductors ixhaphake kwizixhobo zonxibelelwano ezisebenza kwi-frequency range ye-150 ~ 900MHz. Kwisekethe yamandla ejikeleza i-1GHz, ii-inductors ze-microwave zokufudumeza okuphezulu-frequency kufuneka zisetyenziswe. Xa umthengi esebenzisa uhlobo lwe-smt patch, kunjalo, ikwabalulwe kwimiba eyahlukeneyo. Iqela lokucubungula kuphela elinokuqinisekisa ukuba lihlanganiswe ngokwenene kwimarike yokuthengisa emva kokuqwalasela imimiselo yezinga elipheleleyo lomthengi.
