Kwi- chip inductor yemowudi eqhelekileyo , iimveliso ezahlukeneyo zinokukhethwa ngokweempawu kunye neemfuno zobungakanani. I-Gv Electronics, umzi-mveliso we-chip inductor , yabelana nawe ngendlela yokukhetha i-coil echanekileyo ye-COMMon-mode ukusuka kwindawo yokujonga uphawu.
Unokuzifuna ezi Phambi kweOda yakho
1. Usebenzisa njani ukuhanjiswa okwahlukileyo kunye neekhoyili zemowudi eqhelekileyo
Phambi kokuchaza iimpawu zemowudi yokukrwitsha iikhoyili, masiqale sazise ingqikelelo yophawu lwemowudi eqhelekileyo kunye nophawu lwemowudi eyahlukileyo.
Ukuhanjiswa okungafaniyo yindlela esetyenziselwa ukuhanjiswa kwedatha ngesantya esiphezulu. Umzekelo, MIPI? esetyenziswa kwikhamera kunye nesikrini sokubonisa ii-smartphones, i-HDMI?, i-DisplayPort, kunye ne-USB yeekhompyuter zonke ziindlela zokuhambisa ezahlukeneyo.
Kwimizila emibini yokuhanjiswa okwahlukileyo, isigaba somnye nomnye (esibonisa ukutenxa kwe-voltage waveform kunye ne-wave wave yangoku) ukuhanjiswa kwesignali eguqulweyo.
Lo mqondiso ubizwa ngokuba ngumqondiso wemo yokwahlukana, kwaye ukuhanjiswa kwedatha kwenziwa ngomqondiso wemo yokwahlukana. (Imo yomahluko ngamanye amaxesha ibizwa ngokuba yimo yesiqhelo). Xa kuthelekiswa nemiqondiso yendlela yokwahlulahlula, kukho kwakhona umqondiso obizwa ngokuba ngumqondiso wemowudi eqhelekileyo, ehanjiswa kwisigaba esifanayo kwimigca emi-2.
Kwii-inductors zemowudi eqhelekileyo yemigca yesignali, isignali yemowudi eqhelekileyo ngumqondiso ongafunekiyo, oko kukuthi, ingxolo, ebizwa ngokuba yingxolo yemowudi eqhelekileyo.
Imiqondiso yendlela eyahlukileyo ixutywe nengxolo yemowudi eqhelekileyo. Xa isignali yokwahlula ifunyenwe, imiqondiso yemowudi yokwahlula iyomelezana, kwaye ingxolo yemowudi eqhelekileyo iyacima enye nenye. Iindlela zothumelo ezohlukeneyo ezinje azikho lula kwingxolo yemowudi eqhelekileyo.
Izibonakaliso zemitha ezisasazwa ngokwahlukileyo zibonwa kumgama, kwaye imiqondiso ibekwe ngaphezulu komnye nomnye. Ngeli xesha, imiqondiso yendlela yokwahluka iyacima enye nenye, kwaye ingxolo yemowudi eqhelekileyo iyasomeleza. Oko kukuthi, ichaphazeleka kwingxolo yemowudi eqhelekileyo kumgama.
Xa iingxaki ingxolo efanayo kwenzeka, imowudi eqhelekileyo ukuminxa ikhoyili idityaniswe kuthotho ukuya kumgca wothumelo umahluko ukususa ngempumelelo ingxolo imo eqhelekileyo.
2. Ukuqonda kwiimpawu zemowudi yesiqhelo yokuminxa iikhoyili
Ngapha koko, ingxolo yemowudi yokwahlula iyancitshiswa ngandlel’ ithile ngenxa yekhoyili yemowudi eqhelekileyo. Ukongeza, imo yokwahlula-hlula kunye neempawu zemowudi eqhelekileyo zifumana ukuncitshiswa okwahlukeneyo ngenxa yee-frequencies ezahlukeneyo. Iimpawu zekhoyili yemowudi eqhelekileyo imelwe ziimpawu zokuphindaphinda kwendlela yokwahlula ilahleko yokufaka i-Sdd21 kunye nophawu lokufaka lwendlela eqhelekileyo Scc21. (i-Sdd21 kunye ne-Scc21 ziyinxalenye yendlela exutyiweyo ye-4-port S-parameters)
Iimpawu zokuphindaphinda kwelahleko yofakelo lwendlela eqhelekileyo Scc21. Okukhona ilahleko yokufaka inzulu, kokukhona ilahleko inkulu. Ukuphakama kokuphindaphinda kwesiginali yemowudi yokwahlula, kokukhona ilahleko inkulu. Indlela eqhelekileyo yokufaka ilahleko ye-Scc21 yigophe enencopho, kwaye umphumo wokususa ingxolo yemowudi eqhelekileyo iyahluka ngokuxhomekeke kubuninzi.
Ubuninzi bomqondiso we-chip eqhelekileyo i-inductor yendlela yomgca wesignali iyahluka ngokuxhomekeke kwindlela yojongano, kunye nemowudi eqhelekileyo yokukhahlela ikhoyili nayo iyatshintsha ngokufanelekileyo.
Ingaba imowudi yekhoyili yokukrwitsha ifanelekile inokugwetywa ngokwendlela yokudluliselwa kwe-wave wave. Ngokubanzi, ukunqunyulwa okuphindaphindiweyo kwekhoyili yemowudi eqhelekileyo kukuphinda kathathu umqondiso wokuphindaphinda kwenkcazo yosasazo eyahlukileyo. Into ebizwa ngokuba yi-cutoff frequency yi-frequency apho ilahleko yokufaka imo yokwahlukana iba yi-3 dB.
Nangona kunjalo, nokuba kungaphantsi kwamaxesha ama-3, kukho iingxaki ezininzi kwi-wave wave yesiginali, kwaye oku kubhekiselele kokona kulungileyo. (Ngenxa yokuba umgangatho womgangatho womqondiso onje ngemephu yokugqobhoza uchaziwe kujongano ngalunye, ekugqibeleni uyagwetywa ukuba ufanelekile na okanye hayi ngokwalo mgangatho)
Kwelinye icala, ingxolo yengxaki kunye nokuphindaphindwa kwayo kuyahluka ukusuka kwi-terminal ukuya kwi-terminal, kwaye ngokufanelekileyo iimpawu ze-frequency yelahleko efanelekileyo yofakelo lwendlela eqhelekileyo itshintsha ngokufanelekileyo.
Umzekelo, xa kusenzeka ingxolo engaphaya kwexabiso eliqingqiweyo elixelwa ngumgangatho wommiselo wokukhutshwa, kusebenza ngakumbi ukukhetha leyo enelahleko enkulu yofakelo lwemowudi eqhelekileyo kwibhanti yamaza yaloo ngxolo.
Ukongeza, ingxolo yemowudi eqhelekileyo ebonakaliswa lusasazo olwahlukileyo inokuchaphazela kakubi imisebenzi yayo yonxibelelwano olungenazingcingo njenge-LTE kunye ne-Wi-Fi. Inokuqwalaselwa ukuba ingxolo yemowudi eqhelekileyo yefrikhwensi efanayo njengoko unxibelelwano olungenazingcingo lwenzeka, kwaye i-eriyali ifumana le ngxolo. Oku kubizwa ngokuba bubuntununtunu obucinezelweyo. Ngeli xesha, ngokufaka ikhoyili yemowudi eqhelekileyo, ukukhutshwa kwengxolo yemowudi eqhelekileyo kunokucinezelwa kwaye uvakalelo lolwamkelo lunokuphuculwa.
Oku ngasentla sisingeniso kwiimpawu ze-SMD eziqhelekileyo ze-inductors zemodi. Ukuba ufuna ukwazi ngakumbi malunga nee-inductors ze-SMD, nceda uqhagamshelane nathi.
ngokukhethekileyo kwimveliso yeentlobo ezahlukeneyo zombala we-ring inductors, ii-beaded inductors, i-inductors ezithe nkqo, i-tripod inductors, i-patch inductors, i-bar inductors, iikhoyili zemowudi eqhelekileyo, i-high-frequency transformers kunye nezinye izinto ezisebenza ngemagnethi.
