ʻO nā kumu o nā SMD Inductors

Ua lilo ʻo SMD inductor i ʻāpana koʻikoʻi i ka honua o ka uila a me nā ʻoihana uila e kūpono i ka nui liʻiliʻi o nā hāmeʻa. Hoʻolālā ʻia kēia mau inductors e kau pololei ma luna o nā papa kaapuni paʻi (PCB) a ʻaʻole wale lākou he hoʻolālā haʻahaʻa haʻahaʻa e kōkua i ka miniaturization o nā ʻōnaehana uila, akā e hōʻoluʻolu hoʻi i nā ʻanuʻu hui automated, e alakaʻi ana i ke kumu kūʻai haʻahaʻa a me ka manawa pōkole. ʻO ka pili kokoke o kēia mau mea i ka loaʻa ʻole o ka ʻenehana through-hole e hoʻonui nui i ka hoʻolālā a me ka pono o ka hui ʻana a no laila lilo i mea nui i ka hana ʻana i nā kelepona akamai, nā kamepiula puke a me nā mea uila uila ʻē aʻe.

He maikaʻi nā inductors SMD i nā noi kiʻekiʻe ma muli o kāna hoʻolālā. Inā lawe ʻia ka RF (radio frequency) circuit ma ke ʻano he laʻana, ʻo ka compromising parasitic capacitance a me ka inductance o SMD inductor he mea maikaʻi ia i ke kāohi ʻana i ka nalowale o ka hōʻailona a me ka distortion a e hana i nā hōʻailona kamaʻilio maʻalahi. Eia kekahi, ʻo kā lākou hoʻohana ʻana i nā mea hana mana e like me nā mea hoʻoheheʻe ikehu e hōʻike ana i ko lākou laulā.

Hoʻohana pinepine ʻia nā mea hana kiʻekiʻe a me nā ʻenehana hana i ke kūkulu ʻana i nā inductors e hoʻomau i ka hoʻohana nui ʻana a me nā kūlana kūlohelohe i kona ola lawelawe. ʻO ka hopena hopena he ʻāpana e hāʻawi i ka maikaʻi o nā ao ʻelua: paʻa i ka nui a paʻakikī e like me nā kui, ʻo ia ke kumu i hoʻokumu ai nā inductors SMD i ka iwi kuamoʻo o nā mea uila o kēia wā a ʻo ia ka mea hoʻoikaika ma hope o ka hoʻomau ʻana e hana i nā hāmeʻa liʻiliʻi, wikiwiki a hilinaʻi.

Nā ʻano o nā SMD Inductors

Loaʻa nā inductors SMD i nā ʻano like ʻole e kūpono i nā noi a me nā pono. ʻO nā ʻano mea kaulana loa he multilayer inductors, wire-wound inductors, thin-film inductors, a me ceramic core inductors. ʻO nā inductors multilayer he paʻa a kūpono no nā noi alapine kiʻekiʻe aʻo nā inductors ʻeha uea e hōʻike ana i kahi mana o kēia manawa i ʻoi aku ka maikaʻi a kūpono nā mea hope i nā kaʻa lako mana. Hāʻawi nā inductors kiʻi ʻoniʻoni i nā waiwai inductance kūpono no nā noi RF; Hoʻohana ʻia nā inductors core ceramic no ka waiwai Q kiʻekiʻe, nā noi haʻahaʻa haʻahaʻa. ʻO ke koho ʻana i ka mana SMD pono inductor he hana koʻikoʻi i ka hoʻolālā ʻana o ka mea uila no ka hana maikaʻi loa.

Nā kikoʻī e noʻonoʻo ai

Ke koho ʻana i kahi inductor SMD kūikawā no kahi noi kikoʻī, aia kekahi mau kikoʻī e pono e noʻonoʻo ʻia e hōʻoia i ka hoʻohālikelike a me ka hana noi kūpono. ʻO nā palena nui e noʻonoʻo ai he inductance, helu ʻia i kēia manawa, kū'ē (DCR), Q waiwai a me ka nui. Hōʻike maoli ka waiwai inductance iā mākou i ka nui o ka ikehu e hiki ke mālama i ka inductor; ʻoiai ke hōʻike nei ka manawa i helu ʻia i ka manawa kiʻekiʻe i hiki i ka inductor ke lawelawe me ka ʻole o ka wela. ʻO ke kū'ē o ka inductor e pili ana i ka nalowale o ka mana, a ʻo ka haʻahaʻa haʻahaʻa he kiʻekiʻe o ka hoʻohana ʻana i ka mana. ʻO ka Q factor, kahi ana o ka hana inductor i nā noi RF, e haʻi iā ʻoe i ka maikaʻi o ka inductor. ʻO ka hope, lilo ka nui i mea koʻikoʻi i nā hihia i kaupalena ʻia ka loaʻa ʻana o ka wahi. Ma ka noʻonoʻo ʻana i kēia mau hiʻohiʻona, maʻalahi ke koho i ka inductor SMD kūpono.

Ke koho ʻana i ka Inductor SMD kūpono

Ke Anaana i na Koina Kaapuni

He hana koʻikoʻi ke koho ʻana i ka inductor SMD kūpono, no laila ma mua o kou ʻimi hohonu ʻana, he manaʻo maikaʻi ia e hoʻomaopopo i ke ʻano o kāu mau manaʻo. Ma waho aʻe o ke koho cursory o ka hana pinepine a me ka waiwai inductance, nui nā mea e pono ai ʻoe e ʻike e pili ana i ka hana ʻana o kēia mau ʻāpana ʻelua iā ʻoe. No ka laʻana, ke hoʻohana ʻia ka inductor i ka noi alapine kiʻekiʻe e like me RF communication circuit, a i ʻole ka hoʻololi wikiwiki ʻana i ka mana, ʻo ke kūpaʻa inductor series a i ʻole ka hiki ke hōʻemi i ka parasitic i mea nui loa. ʻO ia mau hopena parasitic, hiki ke hoʻokomo i ka capacitive a me nā poho resistive, hiki ke kaupalena i ka hana ma o ka hoʻohui ʻana i ka walaʻau a me ka hōʻemi ʻana i ka pono.

Ke koho ʻana i kāu waiwai E like me ʻoe ʻaʻole e koho i kekahi helu no kahi waiwai inductor (ʻaʻole ia he manaʻo manaʻo a hōʻailona paha), ʻaʻole ʻoe e koho i kahi waiwai like ʻole no ka capacitance ma kahi kaapuni. Pono ka inductor i ka hiki ke mālama i ka paʻa o kēia manawa inā e loli ana ka ukana. He mea pili loa kēia i nā hana hoʻokele mana, ʻoiai ke kōkua nei ka inductor i ka hoʻomaʻamaʻa ʻana o nā ripples voltage a me ka hoʻopaʻa ʻana o ka lako mana puka. Eia kekahi, makemake e lawe i ka helu o kēia manawa o ka inductor i ʻole e hoʻopiha ʻia ka mea kumu. Hoʻemi nui ka Saturation i ka inductance o ke kaapuni a no laila ua nalowale ka hana o ke kaapuni. ʻO ka hopena, he mea koʻikoʻi ke koho i kahi inductor hiki ke mālama i nā koi inductor kiʻekiʻe i kēia manawa me ka ʻole o ka saturating a hana maikaʻi ma luna o nā kūlana hana āpau.

I ka pōkole, ʻoi aku ka nui o ka hoʻoholo ʻana i ka inductor SMD kūpono ma mua o kāna mau kikoʻī: e noʻonoʻo pū kekahi i ke koena o ke kaapuni. Me ka nānā pono i nā hiʻohiʻona e like me ke alapine o ka hana, ka waiwai inductance, ke kūpaʻa o ka series, a me ka helu o kēia manawa, hiki i nā ʻenekini ke koho i ka inductor SMD kūpono ʻaʻole e hui wale akā, hoʻoikaika i ka hana o kā lākou kaapuni. ʻO kēia haʻawina, ʻo ia ke kumu no ka hoʻolālā holoʻokoʻa, he ʻāpana wale nō o ke kaʻina hana hoʻolālā, me ka hoʻokele wela, nā palena nui a me ka launa pū ʻana me nā ʻāpana ʻē aʻe o ka ʻōnaehana e hoʻoponopono ʻia ma hope.

Ka Loiloi ana i ka nui a me ka wawae

He mea koʻikoʻi ka footprint a me ka nui o kahi inductor SMD, ʻoi aku ka nui o nā huahana i kaupalena ʻia. Hoʻopili ka nui i kahi e loaʻa ai ka inductor ma ka PCB, a ʻo ka wāwae wāwae e like me ka papa. ʻO nā mea liʻiliʻi liʻiliʻi e koi pinepine i nā kālepa e komo pū ana me ka hōʻemi ʻana o ka hiki o kēia manawa a i ʻole ka hōʻemi ʻana o ka waiwai inductance, a no laila ke kuʻikahi ma waena o ka nui a me nā koi uila. ʻO ka ʻōlelo lima lima Me kēia kuhikuhi lima nui SMD inductor nui a me kā lākou mau noi maʻamau i ka nānā ʻana:

Code Nui	L x W (mm)	Hoʻohana maʻamau
0201	0.6 x 0.3	ʻO nā mea hana kiʻekiʻe, paʻa
0402	1.0 x 0.5	Mea hoʻohana paʻa lima

Hāʻawi kēia papa o nā code nui inductor i ka ʻike i ka pili ʻana o ka nui o ke kino a me nā wahi i manaʻo ʻia me nā code nui, e kōkua ana i nā ʻenekinia i ke koho ʻana i kahi kumu kūpono e pili ana i nā pono hana, loaʻa kahi PCB a me ka hana i manaʻo ʻia.

Ka maikaʻi a me ka hilinaʻi

ʻO ka maikaʻi a me ka hilinaʻi e hopohopo pinepine i ke koho ʻana i kēlā SMD inductor, no ka mea, hoʻohālikelike kēia i ka paʻa maʻamau a me nā manawa ʻē aʻe o ka lawelawe uila uila. Hōʻike nā inductors kiʻekiʻe kiʻekiʻe i ka hoʻololi induction haʻahaʻa me ka mahana a ua kūkulu ʻia e hiki ke kū i ke koʻikoʻi ma luna o ka thermal a me ka mechanical. Hiki ke hoʻāʻo ʻia ka hilinaʻi ma muli o ka inoa o ka mea hana, nā ʻikepili huahana i loaʻa nā kūlana o ka hoʻāʻo i hāʻawi ʻia e like me AEC-Q200 no nā noi kaʻa a me nā loiloi mea hoʻohana. E noʻonoʻo i nā inductors ʻoi aku ka maikaʻi mai nā mea hoʻolako me ka mōʻaukala o ka mana maikaʻi, a e noiʻi i nā ʻāpana i hōʻoia ʻia a i hōʻoia ʻia e hoʻokō i nā koi o kāu noi. ʻO kēia ala e hōʻoia i ka SMD inductor i koho ʻia e hāʻawi i ka hana o ke kaapuni a me ka ruggedness lōʻihi.

Ma hea e kūʻai ai i nā SMD Inductors

Nā mea hoʻolaha a me nā mea hoʻolako

Inā ʻoe e hoʻomaka ana i kahi papahana e koi ʻia nā inductors SMD (Surface Mount Device), e hoʻopili i nā mea hoʻolaha a me nā mea hoʻolako. ʻO kēia nā mea kūkākūkā ma waena o nā mea hana a me nā mea hoʻohana hope e hāʻawi i nā ʻano mea like ʻole mai nā mea hana like ʻole. Ma ka hana ʻana i ka hoʻohālikelike ʻana i nā specs ʻenehana, kumukūʻai a me ka loaʻa. Hiki i kēia ʻokoʻa ke kūʻai aku i kahi inductor waiwai kūpono no nā kumu like ʻole, ʻo ia hoʻi, no ka hoʻohana ʻana ma waho o ka hoʻohana maʻamau a i ʻole ka hoʻohana ʻana i kahi ʻāpana kikoʻī.

ʻOi aku nā mea hoʻolaha a me nā mea hoʻolako kūleʻa ma mua o kahi mea kūʻai aku - he ʻāpana lākou o ke kaulahao kūʻai. Hāʻawi lākou i kahi papa o ka hilinaʻi ma ke ʻano o ka palapala hōʻoia, ka kulekele hoʻihoʻi, a me ke kākoʻo o nā mea kūʻai aku ʻaʻole e hoʻokaʻawale ʻia i ka wā e hoʻēmi ai i ka pilikia o ke kūʻai ʻana i nā mea uila. No nā papahana nui a/a i ʻole nā ​​​​miona koʻikoʻi, hiki i kēlā kākoʻo ke manaʻo maoli i ka ʻokoʻa ma waena o ka neʻe ʻana i mua a me ka neʻe ʻole ʻana i mua. Eia hou, loaʻa iā lākou ka poʻe i ʻike i ka mea a lākou e kamaʻilio nei a hiki ke hāʻawi i nā ʻōlelo aʻoaʻo loea, kōkua iā ʻoe e koho i nā ʻāpana, a ʻōlelo pū i nā mea ʻē aʻe i ka wā e paʻakikī ai kahi ʻāpana.
