Kedu ihe bụ SMD inductors? Kedu ihe eji ha eme? Ọtụtụ n'ime ha aghọtachaghị nke ọma. Onye nchịkọta akụkọ BIG na-esote ga-enye gị mmeghe zuru oke:
Ndị inductor SMD na-ebuli elu inductor nwere ike dị elu. Ọ nwere njirimara nke miniaturization, àgwà dị elu, nchekwa ike dị elu na nguzogide dị ala. A na-ejikarị ya na bọọdụ ngosi kọmpụta, kọmpụta akwụkwọ ndetu, mmemme ebe nchekwa pulse, na ndị ntụgharị DC-DC.
Enwere ụdị mgbawa 4: mgbawa ihe nkiri dị mkpa, kpara akpa, ọnya waya na inductor multilayer. A na-ejikarị ụdị abụọ nke ụdị ọnya waya na ụdị laminated. Nke mbụ bụ ngwaahịa nke miniaturization nke omenala waya-ọnya inductor; A na-eme nke ikpeazụ site na iji teknụzụ mbipụta multi-layer na teknụzụ mmepụta laminated. Olu dị ntakịrị karịa nke inductor mgbawa mgbawa waya. Ọ bụ isi ngwaahịa emepụtara na ngalaba nke akụrụngwa inductive.
Inductors mgbawa mgbawa dị mkpa nwere njirimara nke idowe Q dị elu, nkenke dị elu, nkwụsi ike dị elu na obere nha n'ime igwe ugboro igwe microwave. A na-etinye ihe ndị dị n'ime electrodes n'otu oyi akwa, na nkesa magnetik na-etinye uche, nke nwere ike hụ na paramita ngwaọrụ mgbe ịrị elu adịghị agbanwe nke ukwuu, ma gosipụta àgwà ọma ugboro ugboro karịa 100MHz.
Njirimara nke inductor mgbawa kpara akpa bụ na inductance olu unit dị na 1MHz kariri inductor mgbawa ndị ọzọ, pere mpe ma dịkwa mfe ịwụnye na mkpụrụ. Ejiri ya dị ka ihe ndọta dị ntakịrị maka nhazi ike.
Njiri mara nke mgbawa mgbawa mgbawa waya bụ ọtụtụ inductance (mH～H), izizi inductance dị elu, obere mfu (nnukwu Q), nnukwu ikike ugbu a, ihe nketa usoro nrụpụta siri ike, ịdị mfe na ọnụ ala, mana ọghọm dị na ọ na-ejedebeghị na n'ihu miniaturization. Ụdị mgbawa nke seramiiki core winding nwere ike idowe inductance kwụsiri ike yana uru Q dị elu n'oge dị elu, yabụ ọ na-anọ ebe na sekit ugboro ugboro.
Induktọ ndị a chịkọtara nwere ezigbo ihe mkpuchi magnetik, njupụta dị elu, yana ezigbo ike ọrụ. Ọdịmma ya bụ obere ngafe, ọnụ ahịa dị elu, obere inductance, yana uru Q dị ala. Tụnyere waya ọnya mgbawa inductors, stacking nwere ọtụtụ uru: obere size, nke na-eme ka miniaturization nke sekit, mechiri emechi magnetik sekit, agaghị egbochi ndị gbara ya gburugburu, na agaghị egbochi ndị agbata obi components, nke bara uru na components High. -njupụta njupụta nke ngwaọrụ; ihe ejikọtara ọnụ, ntụkwasị obi dị elu; ezigbo okpomọkụ na-eguzogide na solderability; mgbe niile udi, adabara akpaghị aka n'elu arịọnụ mmepụta.
