Yuav ua li cas xaiv zaj duab xis Capacitors rau Automotive Electric Rooj? 2025 Kev Tshawb Fawb Kev Lag Luam Cov Ntaub Ntawv muab Cov Lus Teb
Dec 05, 2025| Kev Ua Lag Luam Kev Lag Luam: Kev siv hluav taws xob ua rau kev xav tau kev loj hlob, Kev hloov pauv hauv tsev nrawm dua
Raws li 2025 Tuam Tshoj Lub Zog Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Kev Lag Luam, kev lag luam loj rau cov khoom siv hluav taws xob hauv Suav teb lub zog tsheb tshiab yuav ncav cuag 6.9 billion yuan los ntawm 2025, thaum lub ntiaj teb kev lag luam yuav tshaj 9.4 billion yuan, tswj qhov kev loj hlob txhua xyoo (CAGR) siab dua 23%. Raws li ib feem niche nyob rau hauv tsheb hluav taws xob, hluav taws xob lub rooj tsav tsheb txhawb kev nthuav dav hauv zaj duab xis capacitor xav tau nrog rau qhov nce nkag mus (nrog ntau dua 80% ntawm cov tsheb tshiab uas muaj lub rooj zaum hluav taws xob raws li tus qauv los ntawm 2025).
Hais txog cov khoom siv toj roob hauv pes, cov tuam txhab lag luam hauv tsev tau ua tiav qhov kev ua tiav: Cov tuam txhab ua lag luam xws li Faraday Electronics, Jianghai Co., Ltd., thiab Shengye Electric tau nkag mus rau cov khoom siv hluav taws xob tseem ceeb ntawm cov khoom siv los ntawm cov neeg siv khoom pov thawj. Cov khoom lag luam hauv tebchaws tam sim no tuav 45% kev ua lag luam sib koom hauv kev lag luam automotive zaj duab xis capacitor, sawv cev rau 32 feem pua ntawm cov ntsiab lus nce los ntawm 2020. Txawm hais tias cov khoom lag luam thoob ntiaj teb zoo li WIMA thiab TDK tseem tseem muaj kev lag luam siab - kawg kev lag luam, cov khoom siv hauv tsev muab cov txiaj ntsig zoo ntawm tus nqi -kev ua tau zoo thiab kev xa khoom xa tuaj.
Core Technology: Plaub yam ntxwv tseem ceeb txhais cov khoom sib xws
Zaj duab xis capacitors tau dhau los ua qhov kev xaiv zoo tshaj plaws rau automotive fais fab lub rooj tsav tsheb tswj thiab lim circuits vim lawv plaub tus yam ntxwv: tus kheej - kho muaj peev xwm, kub tsis kam, voltage endurance, thiab ntev lifespan:
Kev kho tus kheej -kho: Thaum qhov kev puas tsuaj hauv cheeb tsam tshwm sim hauv dielectric, txheej txheej metallized cia li vaporizes los ua ib qho chaw insulating, rov ua haujlwm li qub. Cov cuab yeej no ua rau muaj kev ntseeg siab ntawm lub rooj zaum hauv tshuab hluav taws xob (cov ntaub ntawv tshawb fawb qhia tau hais tias 60% txo qis rau tus kheej -kho cov yeeb yaj kiab capacitors).
Kev Ua Haujlwm Kub Kub: Siv cov khoom siv polypropylene (PP) lossis polyester (PET) zaj duab xis ua cov khoom siv hluav taws xob, cov khoom siv hluav taws xob no tiv taus qhov kub ntawm -40℃txog 125 degree, yoog mus rau qhov hloov pauv thermal ib puag ncig hauv automotive interiors.
Voltage Resistance: Zaj duab xis capacitors ua tiav qhov kev ntsuas hluav taws xob ntau tshaj 2000V, deb tshaj qhov qis -voltage yuav tsum tau (feem ntau Tsawg dua lossis sib npaug li 400VDC) ntawm lub rooj zaum hluav taws xob lub cev muaj zog, kom muaj kev ruaj ntseg thaum lub sij hawm hloov pauv voltage.
Ntev Lifespan: Lub cev ruaj khov ntawm cov yeeb yaj kiab yas yeeb yaj kiab ua rau lub neej ntev tshaj 100,000 teev, sib piv cov kev pabcuam hauv tsheb (kwv yees li 8-10 xyoo) thiab txo cov nqi tu mus ntev.
Kev xaiv cov khoom siv xov xwm: PP zaj duab xis, nrog nws qhov qis siab - zaus poob thiab siab dua - qhov kub thiab txias, yog qhov tsim nyog rau kev tswj lub rooj zaum fais fab. PET zaj duab xis, muab tus nqi qis dua, yog qhov zoo tagnrho rau kev lag luam- cov tsheb hauv chav kawm uas yuav tsum tau ua haujlwm nruab nrab.
Phau Ntawv Qhia Kev Xaiv: Plaub -Txoj Kev Xaiv Qhov Zoo
Rau automotive electric seat daim ntaub ntawv, cov kws tshaj lij kev lag luam pom zoo xaiv cov zaj duab xis capacitors raws li plaub yam hauv qab no:

Kev lag luam Trends: Kev ua tau zoo siab thiab kev tsim khoom hauv tsev tawm los ua cov lus qhia tseem ceeb
Cov ntaub ntawv tshawb fawb qhia tau hais tias automotive hluav taws xob lub rooj zaum zaj duab xis capacitors yuav hloov zuj zus nyob rau hauv peb cov lus qhia tseem ceeb:
Kev ua tau zoo: Raws li lub rooj txawj ntse nce qib (xws li, lub rooj zaum nco, qhov cua- kev sib xyaw ua ke cua sov), xav kom lub capacitor teb ceev thiab ruaj khov nce. Cov ntaub ntawv tshiab PP zaj duab xis (xws li nano-cov xov xwm sib xyaw) yuav maj mam tau txais.
Miniaturization: Tsawg qhov chaw sab hauv yuav tsum tau txo qis capacitor ntim ntau dua 30% kom haum rau cov khoom siv hluav taws xob sib xyaw ua ke.
Deepening Domestic Production: Kev tawg los ntawm kev lag luam hauv tsev hauv cov ntaub ntawv zaj duab xis (piv zaj duab xis tus kheej- tam sim no nce mus txog 65%) thiab cov txheej txheem tsim khoom yuav txhawb nqa tus nqi nkag ntawm cov khoom siv hluav taws xob hauv tsev hauv tsheb fais fab ntawm 45% hauv 2025 txog 70% los ntawm 2030.
Cov kws tshaj lij kev lag luam ceeb toom: "Xaiv zaj duab xis capacitors rau automotive hluav taws xob lub rooj zaum yuav tsum ntsuas qhov kev ua tau zoo, kev ntseeg tau, thiab tus nqi. Amid tus qauv mus rau kev hloov pauv hauv tsev, Tuam Tshoj cov khoom lag luam tam sim no ua tau raws li qhov xav tau ntawm siab - qauv kawg thiab yuav dhau los ua kev lag luam tseem ceeb yav tom ntej."
