Phepelo e matla, likarolo tse sa sebetseng li thehile leqhubu le lecha la leruo

Lihlahisoa tse peli tse kholo tsa li-index tsa passive component multilayer ceramic capacitors (MLCC) tsa Samsung Electro-Mechanics tsa Korea Boroa le TDK ea Japane li sa tsoa fana ka tsebiso ho bareki ba semela sa kopano ea pele, ba hatisa hore phepelo ea li-MLCC tse nang le matla a holimo e ntse e le thata, haholoholo tlhokeho ea mehala ea thekeng ea 5G kamora Selemo se Secha sa Ngwedi. Boholo bo lekantsoeng ba lifeme tsa brand mainland bo fihletse khakanyo ea mantlha ea mmaraka ea li-unit tsa limilione tse 500. Ha ho nahanoa ka mokhoa oa mmaraka, theko ea MLCC e tla eketsoa haufinyane.

Ho tlalehiloe hore ponahalo ea litaelo tsa Yageo le Walsin e feta likhoeli tse 'ne,' me e tla fihla halofo ea bobeli ea selemo. Ho lebelletsoe hore litheko li tla nyolloa ka nepo ho fihlela keketseho maemong a mmaraka.

Samsung Electro-Mechanics le TDK ke bafepedi ba bobeli ba MLCC ba bobeli le ba bohlano lefatšeng ka bophara. Bahlahisi bana ba babeli ba ile ba ntša leseli ka nako e le ngoe ka sepheo sa bona sa ho eketsa litheko. Ntle le moo, nako ea karolelano ea morao-rao ea tlhahiso ea lihlahisoa tsa MLCC e fetisitse matsatsi a 112, e telele ka ho fetisisa Ho nka matsatsi a 180 ho totobatsa maemo a mmaraka a chesang mme keketseho ea litheko e bohlokoa.

Ho ea ka bahlahlobisisi ba indasteri, kamora Selemo se Secha sa Machaena, MLCC e na le "moea o matla" o ntseng o phahama, haholo hobane tlhoko ea mmaraka ea li-smartphones tsa 5G e betere ho feta kamoo ho neng ho lebelletsoe, mme moruo oa matlo o sutumetse thepa ea PC le NB ho boloka maemo a holimo- bofelo, le limmaraka tse amanang le likoloi Nka kapele.

Haholo-holo, lifeme tse ling tsa moetapele oa MLCC Nissho Murata Manufacturing li kile tsa emisa tlhahiso ka lebaka la ts'isinyeho e matla ea lefatše e Tohoku, Japane. Leha ba qalile ho sebetsa ka ho latellana, mmaraka o ts'oenyehile hore kakaretso e felletseng ea Murata e tla ameha nakong ea ho emisoa ha mosebetsi. Ha ho tsejoe, ka hona ho reka ka mafolofolo le hona ke matla a mang a bohlokoa ho nyolla theko.

Ho latela tlhahlobo ea phepelo ea thepa, 'marakeng qalong o ne o lebelletse hore boholo ba mmaraka oa mehala ea thekeng oa 5G selemong sena bo tla nyoloha ho tloha ho limilione tse 200 selemong se fetileng ho isa ho limilione tse 500. Leha ho le joalo, kamora ho fela ha matsatsi a phomolo a Selemo se Secha sa Machaena, baetsi ba mehala e mehlano e meholo ea mehala ea thekeng naheng ea China ba ntse ba lelekisa liodara. Palo e hakantsoeng ea mehala ea thekeng ea 5G e tsoang ho baetsi ba bahlano selemong sena e fihlile ho limilione tse 500. Sena ha se kenyeletse baetsi ba li-index tse kholo tsa Samsung le Apple. Bophahamo ba thepa bo bonts'a hore tlhoko ea mmaraka oa mohala oa thekeng oa 5G e matla ho feta likhakanyo tsa mmaraka.

Ha palo ea li-MLCC tse sebelisoang ke mehala ea thekeng ea 5G e eketsehile ka 30% ha e bapisoa le mehala ea thekeng ea 4G, lihlahisoa tse hlano tsa mehala ea thekeng naheng ea China li ekelitse tlhoko ea MLCC ka nako e le ngoe.

Semela sa kopano se senotse hore se sa tsoa amohela tsebiso ho tsoa ho Samsung Electro-Mechanics le TDK, e bonts'itseng hore ka lebaka la tlhoko e matla ea lehae ea lisebelisoa tsa elektroniki tsa phepelo, phepelo ea likarolo tse nang le bokhoni bo phahameng ba MLCC e thata, mme bareki ba tlameha ho ikemisetsa kelellong bakeng sa theko ea MLCC e eketseha neng kapa neng.

Ha maemo a mmaraka a ntse a thatafala, indasteri e lumela hore baetsi ba Taiwan ba joalo ka Yageo le Walsin ba ke ke ba hana ho phahamisa likhakanyo tsa bona ho arabela keketseho e matla ea theko ea baetsi ba Japane le ba Korea. Yageo o boletse hore e ke ke ea fana ka maikutlo mabapi le likhakanyo le litaelo tse fumanoeng ke lithaka tsa eona, empa e tla lekola maemo a mmaraka hantle mme e etse karabo e nepahetseng ka ho fetisisa.

Walsin o arabile hore ponahalo ea MLCC le li-odorsa tsa li-resistor hajoale li feta likhoeli tse 'ne, mme bareki ba se ba qalile ho kenya liodara kotareng ea boraro. Ho lebelletsoe hore haeba phepelo ea semiconductor e fetoha hantle halofong ea bobeli ea selemo, matla a ho romella thepa ea lits'ebetso tse kholo tsa terminal a tla ba matla, mme phepelo ea likarolo tse seng bonolo e tla ba matla. .
