Qaybaha inductance SMD waxaa loo isticmaalaa tiro yar oo wareegyo ah. Waxa kaliya oo loo isticmaalaa dhamaadka wax soo saarka ee sahayda kontoroolka DC-yar ee korantada. Waxaa lala isticmaali karaa capacitors filter si loo sameeyo wareegga filter filter ee CLC-qaabeeya. . Curiyaha inductive wuxuu ka kooban yahay hal gariir, qaarna leh xudunta birlabeedka (inductance weyn), unugga guud ahaan waxaa lagu muujiyaa μH iyo mH, qiimaha hadda wareegaysana waa dhowr milliamps ilaa dhowr boqol oo milliamps.
Waa maxay hababka lagu aqoonsan karo inductors SMD? Warshadda Soo-saarka Korontada ee Gaashaaman ee SMD si ay kula wadaagto.
Habka aqoonsiga inductor SMD, inductor SMD ayaa laga heli karaa foomamka baakadaha wareegsan, labajibbaaran iyo leydi, midabkuna inta badan waa madow. Iyada oo leh inductors xudunta birta (ama inductors), way fududahay in laga garto muuqaalka. Si kastaba ha ahaatee, qaar ka mid ah inductors leydi ah ayaa u eg sida chip resistors marka loo eego muuqaalka. Calaamadda inductor chip ee guddiga wareegga ee soo saaraha inverter-ka waxaa lagu calaamadiyay ereyga L. Xaddiga shaqada ee inductor waxaa ka mid ah inductance, qiimaha Q (Qaybta tayada), caabbinta DC, hadda la qiimeeyay, inta jeer ee is-qabashada, iwm. , laakiin cabbirka inductor chip waa xaddidan yahay, oo intooda badan waxaa lagu calaamadeeyay kaliya inductance, iyo xuduudaha kale aan la calaamadin, oo inta badan waa habka calaamadaynta aan tooska ahayn - calaamadaynta jirka ee inductor chip waa qayb ka mid ah oo kaliya. macluumaadka qeexida iyo qaabka oo dhan, taas oo ah, inteeda badan waa macluumaadka inductance oo keliya.
1. Habka aqoonsiga inductor SMD:
1) Marka laga eego muuqaalka, sida inductor afar gees ah ama wareeg ah oo leh xudunta magnetka, mugga ayaa xoogaa ka weyn, xudunta magnetic iyo gariiradda ayaa la arki karaa;
2) Qaar ka mid ah inductor-ka chip-ka waxay la mid yihiin muuqaalka resistors-ka, laakiin ma jiraan tirooyin iyo xarfo calaamadeysan, kaliya calaamad goobaabin yar, taas oo macnaheedu yahay qaybaha inductance;
3) Tirooyinka taxanaha ah ee qaybaha wareegga waxaa badanaa lagu calaamadeeyaa xarafka L, sida L1, DL1, iwm.
4) Waxaa jira calaamad inductance, sida 100.
5) Caabbinta AC ee inductor ku habboon waa weyn tahay, halka iska caabbinta DC ay eber tahay. Qiimaha iska caabbinta la qiyaasay ee curiyaha soo kicinaya aad buu u yar yahay, oo leh qiime iska caabin ah oo ku dhow eber ohms. Iyada oo la eegayo iyo cabbirka (booska iyo shaqada wareegga), waxay kala saari kartaa in qaybtu tahay resistor chip ama chip inductor, waxayna go'aamin kartaa qaybta inductive-ka.
6) Isticmaal tijaabiye inductance gaar ah si aad u kala gooyso qaybta wareegga una cabbirto inductance.
2. Beddelka qaladka:
1) Qaybaha isku nooc ah ayaa laga saari karaa guddiga qashinka oo la bedeli karaa
2) Marka hore go'aami inductance iyo wareegtada qiimaha hadda, ku beddel qaybaha inductance ee ledhka caadiga ah, oo si fiican u hagaaji
3) Is-dabaylaha, samaynta beddelka inductance, waxaa jira dhibaato gaar ah oo ku saabsan hawlgalka
4) Haddii aysan jirin saameyn muuqata oo ku saabsan waxqabadka wareegga, dayactirka degdegga ah wuxuu noqon karaa mid gaaban oo gaaban
Soo-saareyaasha Chip ee lagu taliyay oo ay dad badan u baahan yihiin
Sida loo doorto inductor hadba baahidaada
Markaad dooranayso badeecad, had iyo jeer dooro badeecada ku saleysan baahiyaha dibadda. Isla sidaas oo kale ayaa loogu talagalay inductance-ka isku-dhafan ee isku-dhafka ah , waxaad u baahan tahay inaad tixgeliso qodobbada, ka dibna dooro kuwa ku habboon hal-xabbo ee chip inductors, inductor-ga gaashaanka leh, iyo inductors power chip. Waxaa jira arrimo badan oo saameeya inductor chip. Aynu ka hadalno sida loo doorto inductor-ka chip-ka iyadoo loo eegayo baahiyaha.
1. Dooro inductor hadba baahida loo qabo
Marka la dooranayo inductor chip ee codsiga awoodda la qaadi karo, saddex dhibcood oo muhiim ah ayaa loo baahan yahay in la tixgeliyo: cabbirka iyo cabbirka, iyo tan saddexaad waa cabbirka. Booska guddiga wareegga ee talefannada gacanta ayaa ku jira qiimo sare, gaar ahaan marka hawlaha sida cayaartoyda, TV-yada iyo muuqaalka lagu daro taleefanka. Kordhinta shaqeyntu waxay sidoo kale kordhin doontaa sawirka hadda ee batteriga. Sidaa darteed, cutubyada dhaqan ahaan ay ku shaqaynayeen nidaamiyayaal toosan ama si toos ah ugu xidhan baytariyada waxay u baahan yihiin xalal awood sare leh. Mid ka mid ah tillaabada loo maro xallinta awoodda sare waa in la isticmaalo beddelaha buck magnetic.
Marka lagu daro cabbirka, shuruudaha ugu muhiimsan ee inductance waa qiimaha inductance ee inta jeer ee beddelka, xannibaadda DC ee gariiradda, qulqulka dheeriga ah ee hadda, hadda RMS dheeraadka ah, is-gaarsiinta isgaadhsiinta ESR iyo qodobka. Iyada oo ku xidhan codsiga, waxa kale oo muhiim ah in doorashada nooca inductor-ka la ilaaliyo ama aan gaashaanka lahayn.
Si la mid ah eexda DC ee ku jirta kombuyuutarka, Iibiyaha A's 2.2µH ayaa laga yaabaa inuu si weyn uga duwan yahay Iibiyaha B's. Xidhiidhka u dhexeeya qiimaha inductance iyo hadda DC ee inductor chip ee kala duwanaanta heerkulka ku habboon waa qalooc aad u muhiim ah, kaas oo ay tahay in laga helo soo saaraha. Joogtada dherjinta ee dheeraadka ah (ISAT) ayaa laga heli karaa qaloocan. ISAT guud ahaan waxaa lagu qeexaa sida hoos u dhaca qiimaha inductance. DC hadda marka qaddarku yahay 30[[%]] ee qiimaha dheeraadka ah. Qaar ka mid ah soosaarayaasha inductor ma laha ISAT joogto ah. Waxay u badan tahay inay bixiyeen hadda DC markii heerkulku 40°C ka sarreeyey heerkulka deegaanka.
Marka inta jeer ee wareejintu ka badato 2MHz, waxaa lagama maarmaan ah in fiiro gaar ah loo yeesho luminta isgaarsiineed ee inductor. ISAT iyo DCR ee soosaarayaasha kala duwan ee soo saarayaasha ee ku taxan heerka caadiga ah ayaa laga yaabaa inay yeeshaan cilado isgaarsiineed oo aad u kala duwan marka loo eego inta jeer ee beddelka, taasoo keentay awood muuqata oo ka hooseysa culeys fudud. kala duwanaansho. Tani waxay muhiim u tahay wanaajinta nolosha batteriga ee nidaamyada korantada la qaadan karo, kuwaas oo waqtigooda intiisa badan ku qaata hurdo, heegan, ama qaab awood yar.
Maadaama ay soo-saareyaasha chip inductor-ka ay dhif tahay inay bixiyaan macluumaadka ESR iyo Q, naqshadeeyayaasha waa inay weydiiyaan iyaga. Xidhiidhka u dhexeeya inductance iyo hadda ay bixiso soo saaraha ayaa inta badan ku xaddidan 25 ° C, markaa xogta ku habboon ee heerkulka hawlgalka waa in la helaa. Heerka ugu hooseeya waa 85 ° C.
