The srew terminal nooca tamarta sare ee capacitor dhoobada sidoo kale loo yaqaan "Doorknob Capacitor" Ingiriisi ama  Korontada Sare ee kaabiyaha Terminal Capacitor. Shirkadda caanka ah ee Japan TDK (Tokyo Denkikagaku Kogyo) waxay u tixraacdaa "Ultra High Voltage Ceramic capacitor." Tan iyo markii shirkadda weyn ee qalabka elektiroonigga ah ee Murata ay ku dhawaaqday joojinta korantada sare ee korantada korantada ee dayrta 2018, saamiga ugu sarreeya ee suuqa Shiinaha waxaa haya astaanta Japan ee TDK. TDK waxay leedahay waayo-aragnimo 40 sano ah oo ku saabsan wax soo saarka iyo suuq-geynta ee korantada ultra-sarey capacitors, kuwaas oo si ballaaran loogu isticmaalo Transformers korontada gudaha Shiinaha, wareegyada wareegga, mashiinnada CT-da caafimaadka-dhamaadka sare, warshadaha NDT tijaabo aan burburin, laser awood sare hubka, koronto-dhaliyeyaasha korantada-sare, iwm. TDK diiradda iibku waa ugu horrayn ee Japan, South Korea, Russia, iyo gobolka Asia-Pacific, iyadoo joogitaanka xad yar ee suuqyada Yurub iyo Ameerika.

 

Tan iyo xilligii Madaxweynihii hore ee Mareykanka Trump, xayiraad ayaa lagu soo rogay shirkadaha Shiinaha ee ku saabsan qaybaha teknolojiyadda sare sida chips-dhamaadka sare iyo qaybaha elektarooniga ah. Shirkado badan oo liiska ku jira, shirkado ay dawladdu leedahay, iyo soosaarayaasha qalabka waaweyn ee Shiinaha ayaa bilaabay in ay tixgeliyaan beddelka gudaha ee qaybaha muhiimka ah. Beddelka iyo bedelida korantada aadka u sarreeya ee TDK capacitors dhoobada ayaa sidoo kale la saaray ajandaha.

 

Dhab ahaantii, qaar ka mid ah soo saaraha sare ee korantada sare ee Shiinaha sida HVC Capacitor ayaa si guul leh u bedelay korantada sare ee xirmooyinka dhoobada dhoobada ah ee caanka ah ee Japanese MURATA iyo brand American Vishay. Xajiyeyaasha HVC waxay ka heleen aqoonsi tijaabo muddo dheer ah shirkado badan oo Yurub iyo Ameerika ah iyo shirkado Fortune 500 ah. Sababtoo ah xaddidaadyada walxaha iyo walxaha, alaabada TDK ma bixiyaan khibrad la mid ah macaamiisha Yurub iyo Maraykanka sida MURATA oo ka socda Japan iyo Vishay oo ka socda Maraykanka. Dhawaan, waxaa jiray jawaab celin ka timid machadyada cilmi-baarista ee Yurub iyo Shiinaha iyo macaamiisha dhammaadka ah oo muujinaya in alaabta TDK ay ka hooseeyaan tayada iyo xuduudaha qaarkood marka loo eego kuwa HVC. Natiijo ahaan, macaamiishu waxay doorteen inay isticmaalaan capacitors HVC halkii ay ka isticmaali lahaayeen alaabada TDK ee Japan. 

1) Korontada lagu dabaqi karo iyo Xaddiga Awooda: TDK ultra-high voltage capacitors dhoobada: 20KV-50KV (Z5T, Y5P, Y5S walxaha); HVC albaabka nooca sare-voltage capacitors dhoobada: 10KV ilaa 150KV (qalabka ugu muhiimsan waa N4700, Y5U, Y5T, iwm). Qaabka ugu sarreeya ee awoodda korantada ee hadda ay bixiso TDK waa FHV-12AN 50KV 2100PF, walxo Y5S. HVC waxay siisaa macaamiisha alaabada caadiga ah sida 50KV 8000PF N4700, 60KV 2000PF N4700, 150KV 1000PF N4700, iyo in ka badan. Marka macaamiishu u baahan yihiin danab shaqaynaya oo ka sarreeya 50KV, capacitors HVC waxay bixin karaan noocyo badan oo hodan ah oo danab sare ah iyo xitaa awood aad u weyn.



2) Intee in le'eg ayaa heerka farsamo ee wanaagsan ee TDK's Z5T, Y5P, Y5S capacitors walxaha dielectric?

Injineerada HVC waxay si dhab ah u cabbireen TDK's 30KV 2700PF iyo 50KV 2100PF capacitors waxayna ogaadeen in inkasta oo TDK ay isticmaasho ceramics Class 2 Y5S, Z5T, iyo walxaha sunta rasaasta ah (oo lagu sheegay inay hoos yimaadaan barnaamijka ka dhaafida ROHS ee shabakadooda), DF (sip factor) qiyamku waxa uu gaadhay heerka darajada 1 ceramik N4700. Tani waxay dhaaftay wax soo saarka dhigooda Shiinaha ee dhinacan.
 

 

3) Qaab dhismeedka gudaha ee capacitors: Xirmooyinka dhoobada aadka u sarreeya ee TDK waxay isticmaalaan qaab-dhismeedka chip-ceramiga ee caadiga ah, iyo caaryada xajinta resin-ka epoxy waxay leedahay cabbir caadi ah oo kaliya 60mm, sida kor ku xusan, taas oo xaddidaysa naqshadda ugu badnaan 50KV 2100PF Y5S capacitor. HVC waxay shaqaaleysiisaa qaab-dhismeed gudaha ah oo hal-abuur leh oo leh taxane laba-chip ah ama isku-xir isbar-bar socda, taas oo awood u siinaysa soo-saarka tifaftirayaasha capacitor oo aad uga badan kuwa soo-saareyaasha caanka ah. Capacitors oo leh koronto sare sida 80KV, 100KV, iyo 150KV waxaa laga soo qaatay isku xirka dual-chip series, halka qiimaha awoodda ee Class 1 ceramic 5000PF iyo xitaa 8000PF lagu gaaro isku xirka dual-chip.


4)Dahaarka saxanka iyo faahfaahin kale: Dusha sare ee chip dhoobada TDK ayaa dhaqan ahaan ku dahaadhi kara awoodda iyada oo loo marayo "dajinta lacagta." Iions Silver waa kirishtaan aad u fiican laakiin sidoo kale waxay u nugul yihiin socdaalka. Taas bedelkeeda, HVC daboolayaasha daboolka gudaha waxay ku daboolaan jajabka dhoobada leh electrodes naxaas ah, iyagoo siinaya iska caabin wanaagsan oo koronto sare ah iyo awoodaha hadda sare leh marka loo eego dahaadhka caadiga ah ee qalinka. (The sawirka kore wuxuu muujinayaa capacitors TDK oo aan lahayn lakabka epoxy resin, laga saaray si uu u muujiyo jajabyo dhoobada ah oo leh dahaadh qalin ah iyo terminal bir ah, iyo sawirka hoose ku muuji tikniyoolajiyadda dahaadhka naxaasta ee u gaarka ah dusha sare ee capacitors HVC.)






Gebagebadii, TDK iyo HVC's screw terminal capacitors dhoobada mid kastaa wuxuu leeyahay faa'iidooyin teknoloji oo u gaar ah, taasoo ka dhigaysa inay si siman u siman yihiin tartamayaasha. Dhinacyada qaarkood, HVC xitaa way ka sarraysaa shirkadda Japan ee TDK. Si kastaba ha ahaatee, iyadoo la tixgelinayo arrimo ay ka mid yihiin wakhtiga hogaanka gaarsiinta iyo qiimaha ay iibsadayaashu had iyo jeer tixgeliyaan, soo jiidashada korantada aadka u sarreeya ee TDK capacitors ayaa si dabiici ah hoos ugu dhacaya marka loo eego HVC.

Astaanta koowaad ee adduunka ee nooca korantada-sare ee capacitors-ka dhoobada waa Japanese Murata. 2018, ka dib markii Murata uu ku dhawaaqay joojinta wax soo saarka, shirkadda Maraykanka ee VISHAY iyo shirkadda Japan ee TDK siday u kala horreeyaan waxay doonayeen inay buuxiyaan faaruqinta suuqa ee uu Murata ka tagay iyagoo soo saaraya war-saxaafadeedyo iyo liiska macluumaadka "tixraac-is-dhaafsiga" ee mareegaha rasmiga ah ee TDK.



Marka la is barbar dhigo Japanese TDK iyo American Vishay, HVC Capacitor ayaa weli ah ikhtiyaarka beddelka fiican ee Murata.

1) Waxaa la ogaan karaa in bedelka TDK ee Murata uu yahay kaliya bedel adag. Tusaale ahaan, Murata's DHS4E4C532KT2B 15KV 5300PF N4700 waxaa la mid ah TDK oo leh beddel u dhigma 15KV 7000PF, Y5S. Waxaan ognahay in inkasta oo walxaha TDK ee Y5S ay muujinayaan waxqabadka khasaare hooseeya, cabbirada dhabta ah waxay muujinayaan qiimayaal la mid ah heerka N4700. Si kastaba ha ahaatee, ceramics-ka heerka 2 sida Y5S ma awoodaan inay ku qabtaan sido kale ceramics-ka heerka 1 ee jawiyada soo noqnoqda. Intaa waxaa dheer, awoodda 7000PF ee TDK waxay noqon kartaa mid aad u weyn macaamiisha caadaystay isticmaalka Murata capacitors, iyo cabbirada ka kooban waxaa laga yaabaa in aanay waafaqsanayn alaabta Murata asalka ah. Iyadoo la tixgelinayo in TDK ay sidoo kale tahay soo-saare caalami ah oo weyn, ilaa macaamiishu ay yihiin kuwo aad u awood badan, TDK waxaa laga yaabaa inaysan diyaar u ahayn inay dib u habeyn ku sameeyaan caaryada oo ay isticmaalaan heer isku mid ah walxaha dhoobada ah ee beddelka Murata.



Haddii HVC ay bixinayso beddelka moodalkan Murata, marka hore HVC liiskeeda alaabada capacitor-ga caadiga ah ayaa ah kan ugu dhammaystiran suuqa ee alaabada terminalka koronto-sare ee korantada, oo ka kooban dhammaan noocyada buug-yaraha ee ka soo jeeda noocyada heerka-sare iyo heerka labaad labadaba gudaha iyo gudaha. caalami ahaan, sida Murata, TDK, Vishay, HVCA, iwm. Asal ahaan, nooc kasta oo Murata ah oo si cad loogu sii daayay internetka ayaa leh xal diyaar ah oo laga sameeyay HVC. Xataa Murata capacitors oo leh cabbir la habeeyey iyo terminal bir ah oo loogu talagalay macaamiisha waaweyn qaarkood oo laga yaabo inaan lagu arki karin onlayn (tusaale ahaan, 40KV 3000PF N4700 capacitor oo ka socda shirkad shucaac ah oo hoos timaada Japan Sumitomo Electric), HVC waxay bixin doontaa 1: 1 xal gaar ah oo aad u badan. qiimaha caaryada hoose. Intaa waxaa dheer, awoodda, dulqaadka, alaabta, iwm, ayaa asal ahaan la mid ah sifooyinka Murata asalka ah, iyo xaaladaha qaarkood, HVC xitaa iyadoo la adeegsanayo fasalka 1 "N4700" alaabta ceramics si loogu beddelo Murata's Class 2 "Z5U" alaabta dhoobada, oo aad u la mid ah Sheeko qadiimi ah oo Shiinees ah oo ah "Rce of the Swift Horse." (田忌赛马)
 

2) Intaa waxaa dheer, in kasta oo TDK ay tahay soo saaraha qaybaha elektaroonigga ah ee Japan ee adduunka caanka ka ah, isgaarsiinta farsamada iyo heerarka adeegga ee laamaha TDK iyo wakiilada ka baxsan Japan uma xoog badna sida wakiilada HVC. Waxaa jiray xaalado marka macmiil ka socda shirkad koronto oo Jarmal ah uu sheegay in markii lagu tijaabiyay labadaba TDK iyo HVC capacitors, wakiilka TDK ma uusan bixin taageero farsamo oo ku filan. Taas bedelkeeda, wakiilka Jarmalka ee HVC, AMEC, wuxuu si firfircoon u booqday macaamiisha muhiimka ah, wuxuu hubiyay qanacsanaanta macaamiisha iyada oo loo marayo isgaarsiin farsamo oo wax ku ool ah, oo muujiyay dabacsanaan xagga hawlgallada ah, taasoo ka tagaysa ra'yi togan macaamiisha. Warshadaha sida qalabka muhiimka ah sida korantada korontada, taageerada farsamada ayaa aad u qiimeeya macaamiisha dhamaadka.

3) Ka dib sanado dadaal ah, HVC Capacitor waxay heshay aqoonsi waxayna kasbatay shixnado badan oo ka yimid macaamiisha capacitor-ka korantada sare sida Nikon, Konica Minolta, GE Healthcare, Johnson & Johnson, Baker Hughes, iyo kuwa kale. Waxqabadka ganacsiga ee macaamiisha Japan iyo shirkadaha Fortune 500 waxay muujinayaan in HVC Capacitor uu buuxiyo shuruudaha farsamo ee adag ee macaamiisha ugu dambeeya ee warshadaha.




Marka la soo koobo, HVC Capacitor waa beddelka ku habboon capacitors-ka korantada sare ee summada Japan ee Murata marka la barbar dhigo TDK. Ilaa xad, alaabada HVC waxay siin karaan macaamiisha jira ee TDK capacitors ultra-high danab khibrad teknoloji oo kala duwan.

Hoos waxaa ah moodooyinka isbarbardhigga ee kala duwanaanta buuxda ee capacitors-ka korantada sare ee TDK iyo HVC:
