xov xwm

Inductors yog cov khoom siv uas tuaj yeem hloov hluav taws xob hluav taws xob mus rau hauv lub zog sib nqus thiab khaws cia. Inductors zoo sib xws hauv cov qauv rau transformers, tab sis tsuas muaj ib qho winding. Inductor muaj qee qhov inductance, uas tsuas yog thaiv qhov kev hloov pauv tam sim no. Txhawm rau ua kom tiav, 5G xov tooj ntawm tes tau hloov kho thiab rov ua dua, hloov pauv hloov pauv, thiab qhov kev thov rau inductors tseem nce ntxiv.

Lub tswv yim ntawm Inductor

Inductors yog cov khoom siv uas tuaj yeem hloov hluav taws xob hluav taws xob mus rau hauv lub zog sib nqus thiab khaws cia. Inductors zoo sib xws hauv cov qauv rau transformers, tab sis tsuas muaj ib qho winding. Inductors muaj qee qhov inductance, uas tsuas yog thaiv qhov kev hloov pauv tam sim no. Yog hais tias tus inductor nyob rau hauv ib lub xeev uas tsis muaj tam sim no ntws, nws yuav sim thaiv cov tam sim no ntws los ntawm nws thaum lub Circuit Court txuas. Yog hais tias tus inductor nyob rau hauv lub xeev ntawm tam sim no ntws, nws yuav sim tswj lub tam sim no tsis hloov thaum lub Circuit Court yog disconnected.

Inductors tseem hu ua chokes, reactors thiab dynamic reactors. Inductor feem ntau yog tsim los ntawm lub moj khaum, winding, shielding cover, ntim khoom, magnetic core los yog hlau core, thiab lwm yam. Inductance yog qhov piv ntawm cov hlau nplaum flux ntawm tus neeg xyuas pib mus rau tam sim no ua rau alternating magnetic flux nyob ib ncig ntawm tus neeg xyuas pib thaum tus neeg xyuas pib hla. lub alternating tam sim no.

Thaum DC tam sim no ntws los ntawm inductor, tsuas yog ib txoj kab hlau nplaum ruaj khov ntawm lub zog tshwm nyob ib puag ncig nws, uas tsis hloov nrog lub sijhawm. Txawm li cas los xij, thaum qhov hloov pauv tam sim no dhau los ntawm lub kauj, cov kab hlau nplaum nyob ib puag ncig nws yuav hloov nrog lub sijhawm. Raws li Faraday txoj cai lij choj ntawm electromagnetic induction - hlau nplaum tsim hluav taws xob, cov kab sib nqus hloov pauv ntawm lub zog yuav ua rau muaj peev xwm induction ntawm ob qho kawg ntawm lub kauj, uas yog sib npaug rau "lub zog tshiab".

Inductors muab faib ua tus kheej inductors thiab kev sib nrig sib inductors. Thaum muaj tam sim no nyob rau hauv lub kauj, magnetic teb yuav raug generated nyob ib ncig ntawm lub kauj.

Thaum tam sim no nyob rau hauv lub kauj hloov, lub magnetic teb nyob ib ncig ntawm nws kuj yuav hloov raws li. Qhov no hloov magnetic teb yuav ua rau lub kauj nws tus kheej tsim induced electromotive quab yuam (induced electromotive quab yuam) (lub electromotive quab yuam yog siv los sawv cev rau lub davhlau ya nyob twg voltage ntawm lub zoo tagnrho fais fab mov ntawm lub active caij), uas yog hu ua nws tus kheej induction.

Thaum ob lub inductance coils nyob ze rau ib leeg, qhov sib nqus teb hloov pauv ntawm ib qho inductance coil yuav cuam tshuam rau lwm qhov inductance coil, uas yog hu ua kev sib nrig sib inductance. Qhov loj ntawm kev sib nrig sib inductor nyob ntawm seb qhov sib txuas ntawm tus kheej inductance ntawm inductance coil thiab ob lub inductance coils. Cov khoom tsim los ntawm kev siv txoj cai no hu ua kev sib nrig sib inductor.

Kev lag luam kev loj hlob ntawm inductor kev lag luam

Chip inductors yog cais los ntawm cov qauv inductor. Raws li kev faib tawm ntawm cov qauv thiab cov txheej txheem tsim khoom, inductors tau muab faib ua ob pawg: plug-in khoom inductors thiab nti mounted inductors. Lub ntsiab tsim tshuab ntawm cov tsoos plug-in inductors yog "winding", uas yog, tus neeg xyuas pib raug mob ntawm cov hlau nplaum los ua ib qho inductive coil (tseem hu ua hollow coil).

Qhov inductor no yog tus cwj pwm los ntawm ntau yam inductance, qhov tseeb ntawm inductance tus nqi, lub zog loj, poob me me, kev tsim khoom yooj yim, lub voj voog luv luv, thiab cov khoom siv raw khoom txaus. Nws qhov tsis zoo yog qhov tsis siv neeg ntau lawm, cov nqi tsim khoom siab, thiab qhov nyuaj hauv miniaturization thiab hnav.

Tuam Tshoj Electronics Industry Association kwv yees tias kev lag luam thoob ntiaj teb inductor yuav loj hlob los ntawm 7.5% txhua xyoo hauv ob peb xyoos tom ntej no, Tuam Tshoj yog cov neeg siv khoom loj ntawm cov khoom siv inductance. Nrog rau kev hloov pauv sai ntawm Tuam Tshoj txoj kev sib txuas lus thev naus laus zis thiab kev tsim kho loj hauv Is Taws Nem ntawm Yam, cov nroog ntse thiab lwm yam kev lag luam, Tuam Tshoj cov chip inductor kev lag luam yuav loj hlob sai dua li kev loj hlob thoob ntiaj teb. Yog tias qhov kev loj hlob yog 10%, kev lag luam loj ntawm nti inductor kev lag luam yuav tshaj 18 billion yuan. Raws li cov ntaub ntawv, lub ntiaj teb no inductor lag luam loj nyob rau hauv 2019 yog 48.64 billion yuan, nce 0.1% xyoo ntawm lub xyoo los ntawm 48.16 billion yuan nyob rau hauv 2018; Xyoo 2020, vim muaj kev cuam tshuam los ntawm thoob ntiaj teb COVID-19, kev lag luam loj ntawm inductors yuav poob mus rau 44.54 billion yuan. Qhov ntsuas ntawm Tuam Tshoj txoj kev lag luam inductor nthuav qhia kev txhim kho. Hauv 2019, qhov ntsuas ntawm Tuam Tshoj cov khoom lag luam inductor yog kwv yees li RMB 16.04 billion, nce ntawm 13% piv nrog RMB 14.19 billion hauv 2018. Hauv 2019, Tuam Tshoj tus inductor muag cov nyiaj tau los nce xyoo los ntawm xyoo, los ntawm 8.136 billion yuan hauv 2014 txog 17 billion yuan. hauv 2019.

Nws xav tias kev lag luam xav tau rau inductors yuav loj dua thiab loj dua, thiab kev lag luam hauv tsev yuav dav dua. Hauv 2019, Tuam Tshoj tau xa tawm 73.378 billion inductors thiab xa tawm 178.983 billion inductors, 2.4 npaug ntawm cov khoom xa tawm.

Hauv 2019, tus nqi xa tawm ntawm Tuam Tshoj tus inductors yog US $ 2.898 billion thiab tus nqi ntshuam yog US $ 2.752 billion.

Tuam Tshoj tus neeg siv khoom siv hluav taws xob kev lag luam saw tau ntsib kev hloov pauv ntau ntxiv los ntawm kev tsim cov khoom lag luam qis qis, OEM rau cov khoom lag luam txawv teb chaws mus rau kev nkag mus rau cov khoom lag luam siab ntxiv, thiab cov khoom lag luam hauv tsev tau dhau los ua lub ntiaj teb ua lag luam. Tam sim no, Tuam Tshoj lub xov tooj smartphone ntau lawm suav txog 70% lossis 80% ntawm lub ntiaj teb tag nrho, thiab cov tuam txhab suav suav ua tus thawj coj hauv nruab nrab thiab tom qab theem ntawm cov khoom siv hluav taws xob thoob ntiaj teb kev lag luam saw, sib dhos thiab lwm yam, Yog li ntawd, raws li kev pom zoo ntawm "tsheb yog zoo li lub xov tooj loj loj" thiab keeb kwm yav dhau los uas cov neeg siv khoom siv hluav taws xob hauv kev lag luam saw lag luam tau xa mus rau hauv kev lag luam ntawm cov tsheb ntse, qhov kev cia siab ntawm cov neeg siv khoom siv hluav taws xob hauv kev lag luam hauv lub neej yav tom ntej yog tsim nyog tos ntsoov rau.

Qhov nce ntawm 5G xov tooj ntawm tes zaus bands tau txhawb nqa kev siv tib lub tsev inductors. Lub ntiaj teb high-frequency inductors tab tom ntsib qhov sib txawv loj thiab cov khoom siv nruj. Piv txwv li, kev hloov ntawm 5G lub xov tooj ntawm tes mus rau hauv lub voj voog hloov. Qhov kev thov rau inductance txuas ntxiv mus ntxiv. Kev sib kis tau coj mus rau kev tshem tawm ntawm lwm cov inductance giants. Cov kev xaiv hauv tsev tau qhib qhov chaw.
