Inductor yamandla we-SMT

Izinzuzo:

1. Ukusetshenziswa kwetheyiphu yenkampani yenethiwekhi ye-SMT

2. Isilinganiso esiphezulu samanje, i-DCR ephansi.

3. Ifanele ukugeleza kabusha kwe-SMT Craft soldering.

4. Yakha ukuthobela kwe-RoHS futhi uhole mahhala

5. High saturation core impahla kanye nosayizi omncane

6. Ukugcwala kwamanzi kufika ku-14 A

7.CD31/CD32/CD42/CD43/CD52/CD53/CD54/CD73/CD75/CD105/CD105 iyatholakala ngokukhetha kwakho.

8. Iphakheji: I-Tape & Reel yokupakisha.

Usayizi nobukhulu:

Izakhiwo zikagesi:

Izicelo:

1. Ukushintsha izilawuli ezinama-voltage aphansi okusebenza (amakhadi ezithombe, ama-PC-Cards ashumekiwe, amabhodi amakhulu)

2.I-converter ehlanganisiwe ye-DC/DC

3. Ukukhanyisa i-LED, Imishini yokuxhumana ephathekayo,

4. Gada, Ikhamera ephathekayo, Telecommunication, imikhiqizo yedijithali

Ungayikhetha kanjani i-chip inductor efanele yokucubungula i-chip ye-SMT?

1. Ububanzi obuphelele be-inductor ye-chip kufanele bube ngaphansi kobubanzi obuphelele be-inductor ukuze kugwenywe izinto zokudambisa ngokweqile ekubangeleni ingcindezi eyeqile ukuze kuguqulwe inani le-inductor lapho amanzi epholile.

2. Ukunemba kwama-chip inductors atholakala emakethe yokuthengisa ngokuvamile kungu-±10%.Uma ukunemba kungaphezu kuka-±5%, kufanele u-ode kusenesikhathi.

3. Amanye ama-chip inductors angashiselwa i-oven reflow kanye ne-wave soldering, kodwa kukhona nama-chip inductors angakwazi ukushiselwa ngokufakwa kwe-wave soldering.

4. Lapho ulungisa kabusha, akunakwenzeka ukufaka esikhundleni se-inductor nge-chip inductor kuphela ngenani le-inductor.Ukuze uqinisekise izici zokusebenza, kuyadingeka futhi ukuqonda ububanzi bemvamisa yokusebenza kwama-chip inductors.

5. Idizayini yokubukeka kanye nesisekelo sokucaciswa kwama-chip inductors kuyafana, futhi idizayini yokubukeka ayinalo uphawu olubalulekile.Lapho u-soldering ngesandla noma ama-patches enziwe ngesandla, kufanele uqaphele kakhulu futhi ungawenzi amaphutha noma uthathe izingxenye ezingalungile.

6. Kulesi sigaba, kukhona ama-chip inductors amathathu ajwayelekile: uhlobo lokuqala, ama-high-frequency inductors okushisa i-microwave.Isebenza kuzinhlelo zokusebenza zebanga lefrikhwensi ezungeze i-1GHz.Uhlobo lwesibili luyi-high-frequency chip inductors.Ifanele uchungechunge lokulawula i-resonance circuit kanye ne-frequency selective power supply circuit.Uhlobo lwesithathu ama-inductors asebenzayo.Ngokuvamile kusebenza kumasekhethi wamandla amashumi ama-megahertz.

7. Imikhiqizo ehlukene isebenzisa ububanzi obuhlukene bamakhoyili kazibuthe.Ngisho noma kusetshenziswa inani elifanayo le-inductor, isilinganiso sokumelana esibonisiwe asifani.Kuluphu yokulawula imvamisa ephezulu, ukukalwa kokumelana kuyingozi kakhulu kunani lika-Q, ngakho-ke nake lapho uklama uhlelo.

8. Kuvunyelwe ukuba yinani lenkomba ye-chip inductance ngokuya ngenani elikhulu lamanje.Lapho isifunda sokuhlinzeka amandla kufanele sibe nesibopho senani elikhulu lamanje, leli nani lenkomba ye-capacitor kufanele licatshangelwe.

9. Uma ama-inductors kagesi asetshenziswa kuma-converter e-DC/DC, usayizi wama-inductors awo ubeka engozini ngokushesha isimo sengqondo sokusebenza sesekethe yamandla.Ngokwesimo sangempela, indlela yokulungisa ikhoyili kazibuthe ngokuvamile ingasetshenziselwa ukushintsha ama-inductors ukuze kuzuzwe imiphumela ebonakalayo.

10. Ama-inductors anenxeba avamile emishinini yokuxhumana esebenza ebangeni lemvamisa lika-150~900MHz.Kumjikelezo wamandla wefrikhwensi ezungeze i-1GHz, kufanele kusetshenziswe ama-inductors we-microwave heat-frequency inductors.Uma ikhasimende lisebenzisa uhlobo lwe-smt patch, vele, lubalulwe ezicini ezihlukahlukene.Iqembu elicubungulayo kuphela elingaqinisekisa ukuthi lihlanganiswe ngempela emakethe yokuthengisa ngemva kokucabangela imithetho yezinga eligcwele lekhasimende.
