IiCapacitors zikho kuyo yonke indawo. Ukusuka kwi-smartphone epokothweni yakho ukuya kwisithuthi sombane esisendleleni kunye negridi yamandla ekhanyisa izixeko ziphela, ii-capacitors zigcina kwaye zikhuphe amandla ombane phantse kuzo zonke izixhobo zanamhlanje. Emva kwala macandelo abalulekileyo kumi ishishini lehlabathi eligxile kakhulu, apho iqaqobana labavelisi lilawula imveliso, itekhnoloji kunye nokubonelela.
Kodwa "owona mkhulu" ayingombuzo olula. Impendulo ixhomekeke kwindlela oyilinganisa ngayo-ngengeniso epheleleyo, ngomthamo wemveliso, okanye ngobunkokeli kwi-teknoloji ethile ye-capacitor. Esi sikhokelo sichonga abavelisi be-capacitor abakhokelayo behlabathi, sicacisa ukuba yintoni eyenza ukuba nganye ibengamele, kwaye sikuncede uqonde ukuba abavelisi be-capacitor yombane ophezulu bangena njani kwindawo ebanzi.
IMarike yeGlobal Capacitor ngokujonga nje
Imarike ye-capacitor yehlabathi lishishini leebhiliyoni zeedola eliqhubeka likhula ngokuthe ngcembe, liqhutywa yimfuno evela kubathengi be-elektroniki, iimoto, amandla avuselelekayo, amaziko edatha, kunye ne-automation yemizi-mveliso. Kule marike, iintlobo ezahlukeneyo ze-capacitor zisebenza iindima ezahlukeneyo:

Icandelo ngalinye lineenkokeli zalo, kwaye ukuqonda lo mahluko ngundoqo ekuphenduleni ukuba ngubani ngokwenene olawula ishishini.
IiKumkani ze-MLCC: IiNkokheli zeCeramic Capacitor
I-Multilayer ceramic capacitors akhawunti esona sabelo sikhulu semarike yecapacitor yehlabathi ngomthamo, kwaye icandelo lilawulwa kakhulu ngabavelisi baseJapan nabaseKorea.
I-Murata Manufacturing (eJapan) yinkokeli yehlabathi engenakuphikiswa kwii-MLCCs, ebambe malunga ne-30-40% yemarike ngokuxhomekeke kwixesha lomlinganiselo. Ngomthamo wenyanga wemveliso kumashumi eebhiliyoni zeeyunithi, i-Murata ilawula kubathengi be-elektroniki, i-elektroniki yeemoto, kunye nemarike ye-AI ye-server ekhula ngokukhawuleza, apho iye yaba yinkokeli yexabiso kwi-2025-2026.
I-Samsung Electro-Mechanics (eMzantsi Korea) ikwinqanaba lomvelisi weMLCC wesibini ngobukhulu kwihlabathi, ithatha malunga ne-18–23% yesabelo sehlabathi. Ikhonkco layo lokubonelela elidityanisiweyo elithe nkqo kunye nesikhundla esomeleleyo kwizinto zombane zabathengi kuyenza ibe ngumboneleli obalulekileyo wee-smartphones, izixhobo zombane zasekhaya, kunye nezinto zebakala lemoto.
UTaiyo Yuden (eJapan) kwaye I-TDK Corporation (eJapan) landela ngokusondeleyo, nganye ibambe malunga ne-10–12% yemarike yeMLCC. I-TDK, kunye ne-EPCOS encedisayo, ikwangumthengisi okwinqanaba eliphezulu lefilim kunye neecapacitors zeceramic kushishino kunye nosetyenziso lweemoto. Kyocera / AVX kwaye IsiYageo (eTaiwan)-eyayifumene i-KEMET ngo-2020-igqibe inqanaba eliphezulu, kunye nabavelisi abathandathu abalawulayo malunga ne-70% yomthamo we-MLCC yehlabathi.
Electrolytic kunye Film Capacitor Powerhouses
Ngaphaya kweekeramics, i-aluminium electrolytic capacitors ibaluleke kakhulu kumandla ombane, ii-inverters, kunye needrive zamashishini, kwaye apha abavelisi baseJapan bakhokela intsimi.
I-Nippon Chemi-Con (eJapan) yinkokeli yehlabathi kwi-aluminiyam electrolytic capacitors, ilawula malunga ne-18% yemarike yehlabathi ngeyona mveliso ibanzi yeepotfoliyo zolu shishino. Nichicon, IRubycon, kwaye Panasonic nazo abadlali ezinkulu, kunye Rubycon evunyiweyo ngokubanzi high-voltage, uyilo ubomi obude esetyenziswa kumbane kunye nabaqhubi LED. Vishay kwaye I-KEMET (ngoku iyinxalenye yeYageo) jikeleza iinkokeli zehlabathi kwitekhnoloji ye-electrolytic kunye ne-tantalum, ukukhonza iimoto, i-aerospace, kunye nokusetyenziswa komkhosi.
Kwicandelo le-filimi capacitor-apho ukuphathwa kwe-voltage ephezulu kunye nokuthembeka kubaluleke kakhulu-iinkokeli ezifana ne-TDK / EPCOS, i-Vishay, i-Panasonic, kunye neqela eliqinileyo labavelisi baseTshayina banikezela imboni ye-electronics yamandla kunye nokugcinwa kwamandla kunye ne-snubber capacitors for converters, inverters, kunye ne-grid applications.
Indima yabavelisi beCapacitor beVoltage High
Njengoko ihlabathi litshintshela kumandla avuselelekayo, izithuthi zombane, kunye nothumelo lwevoltage ethe ngqo yangoku (HVDC), imfuno yeecapacitor ezikhethekileyo ezinombane ophezulu iye yanda. Abavelisi be-capacitor yamandla ombane aphezulu ziingcali ezisemva kwezi zicelo, zivelisa ii-capacitors ezilinganiswe ukusuka kumakhulu eevolthi ukuya kwiikhilovolthi:
