Chip inductors, oo sidoo kale loo yaqaan inductors koronto, waa mid ka mid ah qaybaha ugu badan ee loo isticmaalo alaabada elektiroonigga ah, oo ay ku jiraan yaraynta, tayada sare, kaydinta tamarta sare iyo iska caabbinta hooseeya.Inta badan waxaa laga soo gataa warshadaha PCBA.Marka la dooranayo inductor chip, cabbirada waxqabadka (sida inductance, rated current, factor quality, iwm.) iyo qaabka qaabka waa in la tixgeliyaa.
I. Halbeegyada waxqabadka inductor chip
1. Inductance ee sifooyinka siman: inductor ay sabab u tahay isbedelka heerkulka deegaanka 1 ℃ sameeyay by inductance ee dib u eegis of △ L / △ t iyo asalka inductance L qiimaha marka la barbar dhigo qiimaha nidaamka heerkulka inductor a1, a1 = △ L / L△ t.Marka lagu daro isku-dhafka heerkulka inductor si loo go'aamiyo xasilloonidiisa, laakiin sidoo kale hubi inaad fiiro gaar ah u yeelato kicinta gariirka farsamada iyo da'da ay keento isbeddelka.
2. Iska caabinta xoogga korantada iyo waxqabadka ka hortagga qoyaanka: Qalabka wax-soo-saarka leh ee iska caabbinta xoogga danabku waxay u baahan yihiin inay doortaan inay isticmaalaan walxaha xirmada si ay uga hortagaan qallafsanaanta danabka sare, sida caadiga ah qalabka wax-soo-saarka caabbinta ugu fiican, waxqabadka ka hortagga qoyaanka ayaa sidoo kale ka fiican. .
3. Inductance iyo leexashada la oggol yahay: inductance waxa loola jeedaa xogta magac-u-yaalka ah ee inductance lagu ogaado inta jeer ee looga baahan yahay heerka tignoolajiyada badeecada.Unugga inductance waa Henry, millihen, microhen, nanohen, weecasho ayaa loo qaybiyaa: heerka F (± 1%);heerka G (± 2%);heerka H (± 3%);heerka J (± 5%);heerka K (± 10%);L heerka (± 15%);heerka M (± 20%);heerka P (± 25%);N heerka (± 30%);Inta badan la isticmaalo waa heerka J, K, M.
4. Inta jeer ee la ogaado: ogaanshaha saxda ah ee qadarka inductor L, Q, DCR qiyamka, marka hore waa in ay ku daraan ka beddelka tamarta inductor ee la tijaabinayo sida waafaqsan qodobada, soo dhawaaday inta jeer ee hadda iyo inta jeer ee dhabta ah ee hawlgalka inductor this. , inta ugu habboon.Haddii unugga qiimaha inductor uu u yar yahay sida heerka nahum, inta jeer ee qalabka la cabbirayo wuxuu u baahan yahay in la hubiyo si loo gaaro 3G.
5. Iska caabinta DC: Marka lagu daro qalabka korantada korantada ma tijaabiso iska caabbinta DC, qaar ka mid ah qalabka kale ee inductor iyadoo loo eegayo baahida loo qabo in la qeexo caabbinta ugu badan ee DC, sida caadiga ah ka yar ayaa la jecel yahay.
6. hadda shaqeeya oo weyn: badiyaa qaado 1.25 ilaa 1.5 jeer wakhtiga lagu qiimeeyay inductor sida ugu badan ee hadda shaqeeya, guud ahaan waa in la leexiyaa 50% si loo isticmaalo si aad u badbaado oo la isku halayn karo.
II.Qaabka inductor chip
Dooro inductors codsiyada awooda la qaadi karo, saddexda qodob ee ugu muhiimsan ee la tixgelinayo waa: cabbirka cabbirka, cabbirka cabbirka, cabbirka saddexaad ama cabbirka cabbirka.
Meesha looxa wareegyada ee telefoonada gacanta ayaa ah mid aad u cidhiidhi ah oo qaali ah, gaar ahaan marka lagu daro waxyaabo kala duwan sida MP3 player, TV iyo muuqaalba telefoonka.Shaqaynta korodhay waxay sidoo kale kordhin doontaa isticmaalka hadda ee batteriga.Natiijo ahaan, modules ay hore ugu shaqeeyeen nidaamiyayaal toosan ama si toos ah ugu xiran batteriga waxay u baahan yihiin xalal wax ku ool ah.Talaabada ugu horeysa ee loo maro xal wax ku ool ah waa isticmaalka beddelka buck magnetic.Sida magacaba ka muuqata, inductor ayaa loo baahan yahay markan.
Tilmaamaha ugu muhiimsan ee inductor, ka sokow cabbirka, waa qiimaha inductance ee inta jeer ee beddelka, impedance DC (DCR) ee gariiradda, saturation hadda la qiimeeyay, rms hadda la qiimeeyay, AC impedance (ESR), iyo Q-factor.Iyada oo ku xidhan codsiga, doorashada nooca inductor - gaashaan ama gaashaan - sidoo kale waa muhiim.
Chip inductors waxay u egyihiin muuqaal isku mid ah, mana suurtogal ah in la arko tayada.Dhab ahaantii, waxaad ku qiyaasi kartaa inductance of chip inductors leh multimeter ah, iyo inductance guud ee tayada liidata chip inductors ma buuxin doonaan shuruudaha, iyo qaladku noqon doonaa weyn.
