He aha nā SMD inductors? He aha ia mau mea i hoʻohana ai? ʻAʻole maopopo ka hapa nui o lākou. Na ka mea hoʻoponopono BIG e hāʻawi iā ʻoe i kahi hoʻolauna kikoʻī:
SMD inductors surface mauna kiʻekiʻe-mana inductors. Loaʻa iā ia nā ʻano o ka miniaturization, kiʻekiʻe kiʻekiʻe, kiʻekiʻe ka mālama ʻana i ka ikehu a me ka haʻahaʻa haʻahaʻa. Hoʻohana nui ʻia i nā papa hōʻike kamepiula, nā kamepiula puke, nā polokalamu hoʻomanaʻo pulse, a me nā mea hoʻololi DC-DC.
Aia he 4 mau ʻano o nā mea hoʻokomo puʻupuʻu: ʻāpana kiʻiʻoniʻoni lahilahi, ulana, uea-ʻeha a me multilayer inductors. Hoʻohana mau ʻia nā ʻano ʻano ʻelua o ke ʻano ʻeha uea a me ke ʻano laminated. ʻO ka mea mua he huahana ia o ka miniaturization o nā inductors uea maʻamau; hana ʻia ka hope me ka hoʻohana ʻana i ka ʻenehana paʻi multi-layer a me ka ʻenehana hana laminated. ʻOi aku ka liʻiliʻi o ka leo ma mua o nā mea hoʻokomo puʻupuʻu uea. He huahana koʻikoʻi ia i kūkulu ʻia ma ke kahua o nā ʻāpana inductive.
Loaʻa i nā mea hoʻokomo chip chip kiʻiʻoniʻoni i nā hiʻohiʻona o ka mālama ʻana i ka Q kiʻekiʻe, ka pololei kiʻekiʻe, ke kūpaʻa kiʻekiʻe a me ka liʻiliʻi liʻiliʻi i loko o ka pūnāwai microwave. Hoʻopili ʻia nā electrodes kūloko ma ka papa like, a ua hoʻokaʻawale ʻia ka māhele magnetic, hiki ke hōʻoia i ka loli ʻole o nā ʻāpana o ka mea ma hope o ke kau ʻana, a hōʻike i nā hiʻohiʻona maikaʻi ma luna o 100MHz.
ʻO ka hiʻohiʻona o nā inductors i ulana ʻia ʻo ia ka nui o ka inductance volume ma 1MHz ma mua o nā inductors chip ʻē aʻe, liʻiliʻi i ka nui, a maʻalahi hoʻi e kau ma luna o ka substrate. Hoʻohana ʻia ma ke ʻano he ʻāpana magnetic liʻiliʻi no ka hana mana.
ʻO nā hiʻohiʻona o ka uea-ʻeha chip inductors he ākea ākea o ka inductance (mH～H), kiʻekiʻe inductance pololei, haʻahaʻa poho (nui Q), nui ʻae ʻia i kēia manawa, ikaika hana hana hoʻoilina hoʻoilina, maʻalahi, a me ke kumu kūʻai haʻahaʻa, akā ʻo ka hemahema. i kaupalena 'ia ma hou miniaturization. Hiki i ka ceramic core winding type chip inductor ke hoʻomau i ka inductance paʻa a me ka waiwai Q kiʻekiʻe loa i kēlā alapine kiʻekiʻe, no laila ke noho nei ia i kahi i ka kaapuni kiʻekiʻe.
Loaʻa i nā inductors i hoʻopaʻa ʻia nā waiwai pale magnetic maikaʻi, kiʻekiʻe sintering density, a me ka ikaika mechanical maikaʻi. ʻO nā hemahema he haʻahaʻa hele haʻahaʻa, kumukūʻai kiʻekiʻe, inductance liʻiliʻi, a me ka waiwai Q haʻahaʻa. Hoʻohālikelike ʻia me nā inductors uea ʻeha chip, he nui nā pōmaikaʻi o ka hoʻopaʻa ʻana: ka liʻiliʻi liʻiliʻi, i kūpono i ka miniaturization o ke kaʻapuni, pani ʻia ka magnetic circuit, ʻaʻole e hoʻopilikia i nā ʻāpana a puni, ʻaʻole e hoʻopilikia ʻia e nā ʻāpana pili, i mea e pono ai nā ʻāpana kiʻekiʻe. -ka hoʻokomo ʻana o nā mea hana; hoʻolālā hoʻohui, hilinaʻi kiʻekiʻe; maikaʻi ka wela a me ka solderability; ʻano maʻamau, kūpono no ka hoʻoulu ʻana i ka ʻili.
