ʻO nā inductors nā ʻāpana e hiki ke hoʻololi i ka ikehu uila i ka ikehu magnetic a mālama iā ia.Ua like ke ano o na inductors me na transformers, aka, hookahi wale no wili.Loaʻa i ka Inductor kekahi inductance, ka mea e pale wale i ka loli o kēia manawa.I ka hōʻuluʻulu ʻana, ua hoʻonui ʻia nā kelepona paʻalima 5G, e hoʻomaka ana i kahi pōʻai hou, a ke hoʻomau nei ka koi no nā inductors.

Manaʻo o ka Inductor

ʻO nā inductors nā ʻāpana e hiki ke hoʻololi i ka ikehu uila i ka ikehu magnetic a mālama iā ia.Ua like ke ano o na inductors me na transformers, aka, hookahi wale no wili.Loaʻa i nā Inductors kekahi inductance, kahi e pale wale ai i ka loli o kēia manawa.Inā aia ka inductor i kahi mokuʻāina ʻaʻohe kahe o kēia manawa, e hoʻāʻo ʻo ia e ālai i ke kahe e kahe ana i ka wā e pili ana ke kaapuni.Inā aia ka inductor i ka moku'āina o ke kahe o kēia manawa, e ho'āʻo ʻo ia e hoʻomau i ka hoʻololi ʻole i kēia manawa i ka wā e hemo ai ke kaapuni.

Ua kapa ʻia ʻo Inductors chokes, reactors a me dynamic reactors.Hoʻokumu ʻia ka Inductor me ka framework, winding, shielding cover, packaging material, magnetic core or iron core, etc. Inductance is the ratio of the magnetic flux of the conductor to the current produce the alternating magnetic flux around the conductor when the conductor pass through ke au hou.

Ke holo nei ka mana o DC ma o ka inductor, ʻike wale ʻia kahi laina ikaika o ka ikaika a puni, ʻaʻole ia e loli me ka manawa.Eia nō naʻe, i ka wā e hele ai ke au ʻokoʻa i loko o ka pōʻai, e loli nā laina mākia a puni ia me ka manawa.Wahi a ke kānāwai o Faraday no ka hoʻokomo ʻana i ka electromagnetic – hoʻohua ka magnetism i ka uila, ʻo nā laina magnetic i hoʻololi ʻia o ka ikaika e hoʻoulu i ka mana induction ma nā ʻaoʻao ʻelua o ka coil, ua like ia me kahi "kumu mana hou".

Hoʻokaʻawale ʻia nā inductors i nā inductors ponoʻī a me nā inductors like.Ke loaʻa ka manawa i loko o ka coil, e hana ʻia nā māla magnetic a puni ka coil.

Ke hoʻololi ke au i loko o ka coil, e hoʻololi pū ke kahua magnetic a puni ia.Hiki i kēia pākuʻi hoʻololi ke hana i ka coil ponoʻī e hoʻoulu i ka ikaika electromotive induced (induced electromotive force) (hoʻohana ʻia ka mana electromotive e hōʻike i ka volta terminal o ka lako mana kūpono o ka mea hana), i kapa ʻia ʻo self induction.

I ka pili ʻana o ʻelua inductance coils i kekahi i kekahi, ʻo ka hoʻololi ʻana o ke kahua magnetic o hoʻokahi inductance coil e hoʻopilikia i ka coil inductance ʻē aʻe, i kapa ʻia ʻo mutual inductance.ʻO ka nui o ka inductance inductor e pili ana i ke kiʻekiʻe o ka hui ʻana ma waena o ka inductance ponoʻī o ka inductance coil a me nā coils inductance ʻelua.ʻO nā ʻāpana i hana ʻia me ka hoʻohana ʻana i kēia kumu i kapa ʻia ʻo mutual inductor.

Kūlana hoʻomohala mākeke o ka ʻoihana inductor

Hoʻokaʻawale ʻia nā inductors chip e ka ʻōnaehana inductor.E like me ka hoʻokaʻawale ʻana o ke kaʻina hana a me ke kaʻina hana, ua māhele ʻia nā inductors i ʻelua mau ʻāpana: plug-in solid inductors a me chip mounted inductors.ʻO ka ʻenehana hana nui o nā inductors plug-in maʻamau ʻo "winding", ʻo ia hoʻi, ua ʻeha ka conductor ma ke kumu magnetic e hana i kahi coil inductive (ʻike pū ʻia he hollow coil).

Hōʻike ʻia kēia inductor e kahi ākea o ka inductance, kiʻekiʻe kiʻekiʻe o ka inductance waiwai, ka mana nui, ka liʻiliʻi liʻiliʻi, ka hana maʻalahi, ka pōkole hana pōkole, a me ka lako pono o nā mea maka.ʻO kona mau hemahema he haʻahaʻa haʻahaʻa o ka hana maʻalahi, ke kumu kūʻai kiʻekiʻe, a paʻakikī i ka miniaturization a me ka māmā.

Manaʻo ka China Electronics Industry Association e ulu ka mākeke inductor honua e 7.5% i kēlā me kēia makahiki i nā makahiki e hiki mai ana, he mea kūʻai nui ʻo Kina i nā mea hana inductance.Me ka hoʻololi wikiwiki o ka ʻenehana kamaʻilio Kina a me ke kūkulu nui ʻana o ka Internet of Things, nā kūlanakauhale akamai a me nā ʻoihana pili ʻē aʻe, e ulu wikiwiki ana ka mākeke chip inductor o Kina ma mua o ka ulu ulu honua.Inā he 10% ka ulu ʻana, ʻoi aku ka nui o ka mākeke o ka ʻoihana inductor chip ma mua o 18 biliona yuan.Wahi a ka ʻikepili, ʻo ka nui o ka mākeke inductor honua ma 2019 he 48.64 biliona yuan, ʻoi aku ka 0.1% makahiki ma ka makahiki mai 48.16 biliona yuan ma 2018;I ka makahiki 2020, ma muli o ka hopena o ka honua COVID-19, e emi ana ka nui o ka mākeke o nā inductors i 44.54 biliona yuan.ʻO ka nui o ka mākeke inductor o Kina e hōʻike i ka hoʻomohala ʻana.Ma 2019, ʻo ka nui o ka mākeke inductor Kina e pili ana i RMB 16.04 biliona, kahi hoʻonui o 13% i hoʻohālikelike ʻia me RMB 14.19 biliona ma 2018. I ka makahiki 2019, ua hoʻonui ʻia ka loaʻa kālā kūʻai inductor o Kina i kēlā me kēia makahiki, mai 8.136 biliona yuan ma 2014 i 17.045 biliona. i ka makahiki 2019.

Manaʻo ʻia e piʻi a nui aʻe ka makemake o ka mākeke no nā inductors, a ʻoi aku ka nui o ka mākeke kūloko.I ka makahiki 2019, ua hoʻokuʻu aku ʻo Kina i 73.378 biliona inductors a lawe mai i 178.983 biliona inductors, 2.4 mau manawa i ka nui o ka lawe ʻana.

I ka makahiki 2019, ʻo ka waiwai kūʻai aku o nā inductors o Kina he US $ 2.898 biliona a ʻo ka waiwai lawe mai he $ 2.752 biliona.

Ua ʻike ʻia ka ʻoihana uila uila o Kina i ka hoʻololi ʻana mai ka hana ʻana i nā ʻāpana haʻahaʻa haʻahaʻa, OEM no nā pahu pahu haole a hiki i ke komo ʻana o nā loulou hana hoʻohui waiwai kiʻekiʻe, a ua lilo nā pahu pahu kūloko i poʻokela honua.I kēia manawa, ʻo 70% a i ʻole 80% o ka nui o ka honua ka hana kelepona ʻo Kina, a ʻo nā ʻoihana Kina e noho aliʻi i ka waena a me nā pae hope o ke kaulahao ʻenehana mea kūʻai aku honua, hui a me nā kula ʻē aʻe, no laila, ma lalo o ka ʻae ʻana o ka ʻenehana "ʻo ke kaʻa. e like me ke kelepona paʻa nui" a me ke ʻano o nā ʻoihana kaulahao mea kūʻai aku i kau ʻia ma ke kahua o nā kaʻa akamai, ʻo ka manaʻolana o ke kaulahao ʻoihana uila mea kūʻai aku i ka wā e hiki mai ana.

ʻO ka hoʻonui ʻana i ka nui o nā kaha kelepona kelepona 5G ua hoʻonui nui i ka hoʻohana ʻana i nā inductors hoʻokahi.Ke kū nei nā inductors kiʻekiʻe o ka honua i kahi ākea nui a me ka lako paʻa.I ka hōʻuluʻulu ʻana, ʻo ka hoʻololi ʻana o nā kelepona paʻalima 5G i hoʻomaka i kahi pōʻai.Ua piʻi mau ka koi no ka inductance.Ua alakaʻi ʻia ka maʻi ahulau i ka haʻalele ʻana o nā mea nunui inductance.Ua wehe ʻia nā wahi ʻē aʻe o ka home.
