Umahluko phakathi kwe-inductor kunye ne-inductor eqhelekileyo| PHILA

Abahlobo abaqondayo ii- inductors bayazi ukuba kukho iintlobo ezimbini zee-inductors kuluhlu lwee-inductors: i-inductors ekhuselekileyo kunye ne-inductors engakhuselekanga. Kwinqaku elidlulileyo, siphinde sikhankanye ezi ntlobo zimbini ze-inductors, kodwa azizange zithelekise kunye. Namhlanje, nabavelisi be-inductor beza nawe ukuze baqonde umahluko phakathi kwee-inductors ezikhuselekileyo kunye nee-inductors ezingakhuselekanga.

Umahluko phakathi kwee-inductors ezikhuselekileyo kunye nee-inductors ezingakhuselwanga

Ucinga ukuba zonke ii-inductors ezijikelezileyo zikhuselekile? I-inductor ekhuselekileyo yi-inductor ejikelezwe ngumbindi wemagnethi. Ayizizo zonke ii-inductors ezijikelezwe zii-cores ezikhuselweyo, ezinje nge-GNL inductors, ezikwangqongwe zii-cores kodwa zingakhuselwanga. Kubalulekile ukuhlukanisa i-inductors ekhuselekileyo kunye ne-inductors ngaphandle ukuze inqume ukuba i-inductor ijikelezwe ngumbindi wamagnetic. Izinga lokuhlaselwa kwe-inductance

Ngokubanzi, i-inductance engakhuselekanga ucingo olunamelelo luvezwa ngaphandle ngaphandle kwesikhuselo semagnethi; Ukukhusela i-inductor enemagnethi yokukhusela, ukuxhathisa okulungileyo kwe-EMI, ukunciphisa ukuphazamiseka kwe-electromagnetic ye-inductor kwihlabathi langaphandle, ukunciphisa ukuphazamiseka kwentsimi ye-electromagnetic eyenziwa yisekethe kwamanye amacandelo.

Ngapha koko, kukho umahluko omkhulu phakathi kwe-inductance ekhuselekileyo kunye ne-inductance engakhuselekanga kukuba i-inductance ekhuselweyo yisekethe yamagnetic evaliweyo, ngelixa i-inductance engakhuselekanga yisekethe yamagnetic evulekileyo. Into ebizwa ngokuba yi-circuit magnetic evaliweyo ithetha ukuba yonke i-circuit magnetic evaliweyo yenziwe ngezinto eziphathekayo, ngelixa i-circuit magnetic evulekileyo ithetha ukuba kukho i-gap yomoya ebonakalayo kwi-circuit magnetic. Ixabiso lokuthepha i-Inductor Co

Azifani nje kuphela, kodwa zikho ezinye ezifanayo. Umthamo wabo ngokuqhelekileyo uncinci, umphezulu kulula ukunamathela, ulungele imveliso ezenzekelayo, ngokweemfuno ezahlukeneyo zabathengi ukuvelisa imilinganiselo yobungakanani obuhlukeneyo abathengi ukuba bakhethe. Ukuthetha ngokuthelekisayo, i-inductor engakhuselekanga inokuchasana kwe-welding engcono kunye nokumelana nobushushu, ilungele i-welding ngokubanzi kunye ne-reflow welding, ngexabiso eliphantsi.

Inductor edibeneyo kunye nokwahlukana okuqhelekileyo kwe-inductor

Ukuchaneka kwe-inductor edibeneyo iphezulu kancinane kune-inductor eqhelekileyo. Ngokubanzi, i-inductors ehlanganisiweyo i-20% echanekileyo kuphela, ngelixa ezinye i-inductors zethu ziyi-10%. Nokuba ezinye ii-inductors zinokuchaneka okungcono, okufana ne-5%, xa kuthelekiswa ne-20% yee-inductors ezidibeneyo. Kuba ukuchaneka kwe-inductor ehlanganisiweyo kungalunganga, kutheni uthatha isabelo esikhulu semarike?

Oku kungenxa yokuba i-inductors edibeneyo ineenzuzo ngokubhekiselele kumaxabiso e-inductance. Inoluhlu olumxinwa lwamaxabiso ovakalelo. Ngokuqhelekileyo, ixabiso layo le-inductance lingaphantsi kwe-100uH, kwaye ezinye iintlobo ze-inductors ezidibeneyo zinokufikelela kwixabiso le-inductance ngaphantsi kwe-1uH. Umyinge wokucofa umyinge ucatshulwe

Siyazi ukuba i-inductance edibeneyo kunye ne-inductance eqhelekileyo kwingqiqo yamanani, umehluko phakathi kwe-inductor yangoku edibeneyo inkulu, ukuba ingqiqo yabo yenombolo yi-10 er, i-inductance current edibeneyo inokwenza okuninzi, umyinge we-inductor yangoku incinci, ngoko ke abanye iimveliso zeemfuno zamanani aziphezulu, kodwa kwimeko yangoku enkulu, ukusetyenziswa kwe-inductance edibeneyo kuninzi, njengekhompyutheni kunye nezinye iindawo.

Oku kukwaziswa kwee-inductors, ukuba ufuna ukwazi ngakumbi malunga ne-patch inductors, nceda uqhagamshelane inductor.
