I-Chip inductors, eyaziwa ngokuba yi-inductors yamandla, yenye yezona zinto zisetyenziswa ngokuqhelekileyo kwiimveliso ze-elektroniki, ezibonisa i-miniaturization, umgangatho ophezulu, ukugcinwa kwamandla aphezulu kunye nokuchasana okuphantsi.Ihlala ithengwa kwiifektri zePCBA.Xa ukhetha i-chip inductor, iiparitha zokusebenza (ezifana ne-inductance, i-rated current, i-quality factor, njl.) kunye nefom yefom kufuneka ithathelwe ingqalelo.
I. Iiparamitha zokusebenza kwe-chip inductor
1. I-inductance yeempawu ezigudileyo: i-inductor ngenxa yokutshintsha kobushushu bendalo 1 ℃ eyenziwe yi-inductance yokuhlaziywa kwe-△ L / △ t kunye nexabiso lokuqala le-inductance L xa kuthelekiswa nexabiso lenkqubo ye-inductor yokushisa a1, a1 = △ L / L△ t.Ukongeza kwi-coefficient yokushisa kwe-inductor ukumisela ukuzinza kwakhe, kodwa qiniseka ukuba ubeke ingqalelo kwi-inductance ye-vibration yomatshini kunye nokuguga okubangelwa utshintsho.
2. Ukumelana namandla ombane kunye nokusebenza kothintelo lokufuma: Kwizixhobo eziguquguqukayo ezinokuxhathisa amandla ombane kufuneka ukhethe ukusebenzisa imathiriyeli yepakethe ukuxhathisa ubungqwabalala bamandla ombane aphezulu, ngokwesiqhelo ezona zixhobo zifanelekileyo zokumelana nombane, ukusebenza kokuthintela ukufuma nako kungcono. .
3. I-Inductance kunye nokutenxa okuvunyelweyo: i-inductance ibhekisela kwidatha ye-nominal ye-inductance efunyenwe ngokuphindaphindiweyo okufunwa ngumgangatho weteknoloji yemveliso.Iyunithi ye-inductance nguHenry, i-millihen, i-microhen, i-nanohen, i-deviation ihlukaniswe: Inqanaba le-F (± 1%);inqanaba G (± 2%);inqanaba H (± 3%);inqanaba J (± 5%);Inqanaba le-K (± 10%);inqanaba L (± 15%);Inqanaba le-M (± 20%);inqanaba le-P (± 25%);inqanaba N (± 30%);eyona isetyenziswayo nguJ, K, M level.
4. Ukufunyanwa rhoqo: ukufunyanwa ngokuchanekileyo kwexabiso le-inductor L, Q, i-DCR yamaxabiso, kufuneka kuqala yongeze i-alternating current kwi-inductor evavanywa ngokuhambelana namalungiselelo, ngokusondeleyo i-frequency yangoku kwi-frequency yangempela yokusebenza yale inductor. , kokukhona kufanelekile.Ukuba iyunithi yexabiso le-inductor incinci njengenqanaba le-nahum, ukuphindaphinda kwezixhobo eziza kulinganiswa kufuneka kuhlolwe ukufikelela kwi-3G.
5. ukuxhathisa DC: Ukongeza izixhobo inductor amandla ayivavanyi ukuxhathisa DC, ezinye izixhobo inductor ngokwemfuneko ukucacisa ubuninzi ukuxhathisa DC, ngokuqhelekileyo ezincinane ezinqwenelekayo.
6. ukusebenza kwangoku okukhulu: ngokuqhelekileyo kuthatha i-1.25 ukuya ku-1.5 amaxesha alinganisiweyo ngoku i-inductor njengowona mkhulu osebenzayo ngoku, ngokuqhelekileyo kufuneka ihlanjululwe yi-50% ukuze isetyenziswe ukuba ikhuseleke ngakumbi kwaye ithembekile.
II.Ifom ye-chip inductor factor
Khetha ii-inductors kwizicelo zamandla eziphathwayo, ezona ngongoma zintathu zibalulekileyo ekufuneka uziqwalasele zezi: ubungakanani bobungakanani, ubungakanani besayizi, eyesithathu okanye isayizi.
Indawo yebhodi yesekethe yeeselfowuni iqinile kwaye ixabiseke kakhulu, ngakumbi njengoko iimpawu ezahlukeneyo ezifana nabadlali beMP3, iTV kunye nevidiyo zongezwa kwifowuni.Ukusebenza okwandisiweyo kuya kwandisa ukusetyenziswa kwangoku kwebhetri.Ngenxa yoko, iimodyuli eziye zanikwa amandla ngaphambili ngabalawuli bomgca okanye zixhunywe ngokuthe ngqo kwibhetri zifuna izisombululo ezisebenzayo.Inyathelo lokuqala elibhekiselele kwisisombululo esisebenza ngakumbi kusetyenziso lwesiguquli se-magnetic buck.Njengoko igama lisitsho, i-inductor iyafuneka kweli nqanaba.
Iimpawu eziphambili ze-inductor, ngaphandle kobukhulu, ixabiso le-inductance ekutshintsheni i-frequency, i-DC impedance (DCR) yekhoyili, i-saturation yangoku, i-rms yangoku, i-AC impedance (ESR), kunye ne-Q-factor.Ngokuxhomekeke kwisicelo, ukhetho lohlobo lwe-inductor - olukhuselekileyo okanye olungakhuselekanga - lubalulekile.
I-chip inductors ibonakala ifana kakhulu ngenkangeleko, kwaye akunakwenzeka ukubona umgangatho.Enyanisweni, unokulinganisa i-inductance ye-chip inductors nge-multimeter, kunye ne-inductance jikelele ye-chip inductors esemgangathweni ayiyi kuhlangabezana neemfuno, kwaye impazamo iya kuba nkulu.
