ʻO ka srew terminal type high voltage ceramic capacitor i kapa ʻia ʻo "ʻO Doacnob Capacitor" ma ka ʻōlelo Pelekania a i ʻole  Kiekie Voltage Screw Terminal Ceramic Capacitor. ʻO ka hui Iapana kaulana ʻo TDK (Tokyo Denkikagaku Kogyo) e pili ana iā ia ʻo "Ultra High Voltage Ceramic capacitor." No ka mea, ua hoʻolaha ʻo Murata i ka hoʻopau ʻana o nā capacitor capacitors screw screw kiʻekiʻe i ka hāʻule o 2018, ʻo ka mākeke kiʻekiʻe loa ma Kina e paʻa ana e ka brand Japanese TDK. ʻO TDK ma mua o 40 mau makahiki o ka ʻike i ka hana ʻana a me ke kūʻai aku ʻana i nā capacitors seramika ultra-kiʻekiʻe, i hoʻohana nui ʻia i nā mea hoʻololi mana home Kina, nā mea hoʻokele kaapuni, nā mīkini CT lapaʻau kiʻekiʻe, nā ʻoihana NDT non-destructive hoʻāʻo, kiʻekiʻe-mana laser. mea kaua, kiʻekiʻe-voltage electrostatic precipitators, etc. TDK ka mea kūʻai i ka manaʻo nui ma Iapana, South Korea, Rusia, a me ka ʻāina ʻo Asia-Pākīpika, me ka emi iki o ka noho ʻana ma nā mākeke ʻEulopa a me ʻAmelika.

 

Mai ka wā o ka Pelekikena Pelekikena mua ʻo Trump, ua kau ʻia nā mea paʻa i nā hui Kina e pili ana i nā mea ʻenehana kiʻekiʻe e like me nā ʻāpana kiʻekiʻe a me nā ʻāpana uila. Ua hoʻomaka ka nui o nā hui i helu ʻia, nā ʻoihana mokuʻāina, a me nā mea hana lako nui ma Kina e noʻonoʻo i nā koho ʻokoʻa no nā mea nui. ʻO ke koho a me ka hoʻololi ʻana o nā capacitors seramika kiʻekiʻe kiʻekiʻe o TDK ua kau ʻia ma ka papa kuhikuhi.

 

ʻO ka mea ʻoiaʻiʻo, ua hoʻololi maikaʻi kekahi mau mea hana capacitor ceramic kiʻekiʻe kiʻekiʻe Kina e like me HVC Capacitor i nā capacitor seramika kiʻekiʻe voltage screw terminal ceramic mai ka inoa kaulana Iapana MURATA a me ka inoa ʻAmelika ʻo Vishay. Ua loaʻa i nā capacitors HVC ka ʻike hoʻāʻo lōʻihi mai nā hui helu ʻEulopa a me ʻAmelika a me nā hui Fortune 500. Ma muli o nā palena waiwai a me nā mea hoʻohui, ʻaʻole hāʻawi nā huahana TDK i ka pae like o ka ʻike no nā mea kūʻai aku ʻEulopa a me ʻAmelika e like me MURATA mai Iapana a me Vishay mai ʻAmelika Hui Pū ʻIa. I kēia mau lā, ua loaʻa nā manaʻo mai nā keʻena noiʻi ʻEulopa a me Kina a me nā mea kūʻai aku hope e hōʻike ana he haʻahaʻa nā huahana TDK i ka maikaʻi a me kekahi mau palena i hoʻohālikelike ʻia i nā capacitors HVC. ʻO ka hopena, ua koho nā mea kūʻai aku e hoʻohana i nā capacitors HVC ma kahi o nā huahana TDK Iapana. 

1) Voltage pili a me ka laulā: ʻO TDK nā mea hoʻoheheʻe uila kiʻekiʻe loa: 20KV-50KV (Z5T, Y5P, Y5S mau mea); HVC doorknob type high-voltage ceramic capacitors: 10KV a 150KV (nā mea nui he N4700, Y5U, Y5T, etc.). ʻO ke kumu hoʻohālike capacitance kiʻekiʻe loa i hāʻawi ʻia e TDK i kēia manawa ʻo FHV-12AN 50KV 2100PF, Y5S mea. Hāʻawi ʻo HVC i nā huahana maʻamau i nā mea kūʻai aku e like me 50KV 8000PF N4700, 60KV 2000PF N4700, 150KV 1000PF N4700, a ʻoi aku. Ke koi nei nā mea kūʻai aku i ka volta hana ma mua o 50KV, hiki i nā capacitors HVC ke hāʻawi i kahi ʻano nui o nā volta kiʻekiʻe a me nā capacitances nui loa.



2) Pehea ka pae ʻenehana maikaʻi o nā capacitors dielectric material o TDK Z5T, Y5P, Y5S?

Ua ana maoli nā mea ʻenekinia o HVC i ka TDK's 30KV 2700PF a me 50KV 2100PF screw capacitors a ʻike ʻia ʻoiai ʻo TDK e hoʻohana ana i ka Class 2 ceramics Y5S, Z5T, a me nā mea i loaʻa i ke alakaʻi (i ʻōlelo ʻia aia ma lalo o ka ROHS exemption program ma kā lākou pūnaewele), ʻo ka DF (dissipation factor) hiki i nā waiwai ke kiʻekiʻe o ka papa 1 ceramic N4700. ʻOi aku kēia ma mua o nā huahana o nā hoa Kina ma kēia ʻano.
 

 

3) ʻO ka hana kūloko o nā capacitors: Hoʻohana ka TDK's ultra-high voltage ceramic capacitors i ka hana kuʻuna ceramic chip structure, a ʻo ka epoxy resin encapsulation mold ka nui maʻamau o 60mm wale nō, e like me ka mea i ʻōlelo ʻia ma luna nei, e kaupalena ana i ka hoʻolālā i ka nui o 50KV 2100PF Y5S capacitor. Hoʻohana ʻo HVC i kahi hoʻolālā kūloko hou me ka moʻo pālua-chip a i ʻole pili like, hiki ke hana i nā kikoʻī capacitor ma mua o nā mea hana kaulana. Loaʻa nā capacitor me nā voli kiʻekiʻe e like me 80KV, 100KV, a me 150KV mai nā pilina ʻelua-chip series, aʻo nā waiwai capacitance o Class 1 ceramic 5000PF a hiki i 8000PF ke loaʻa ma o nā pilina pili pālua-chip.


4)ʻO ka uhi disc a me nā kikoʻī ʻē aʻe: Hoʻopili ʻia ka capacitance o ka TDK ceramic chip ma o ka "plating silver". ʻO nā ion kālā he mea hoʻokele maikaʻi loa akā hiki nō hoʻi i ka neʻe ʻana. ʻO ka ʻokoʻa, hoʻokomo nā capacitors screw HVC i loko o ka chip ceramic me nā electrodes keleawe, e hāʻawi ana i ke kūʻē maikaʻi ʻana i ka volta kiʻekiʻe a me nā mana kiʻekiʻe o kēia manawa i hoʻohālikelike ʻia me ka plating kālā maʻamau. (ʻO ka kiʻi ma luna hōʻike i nā capacitors TDK me ka ʻole o ka epoxy resin layer, wehe ʻia e hōʻike i nā ʻāpana seramika me ka hoʻopaʻa kālā a me nā pahu metala, a me ka kiʻi ma lalo hōʻike i ka ʻenehana hoʻoheheʻe keleawe kū hoʻokahi ma ka ʻili o nā capacitors HVC.)






I ka hopena, ʻo TDK a me HVC's screw terminal type ceramic capacitors ua loaʻa i kēlā me kēia mea ko lākou pono ʻenehana ponoʻī, e hoʻohālikelike ana iā lākou i nā mea hoʻokūkū. Ma kekahi mau hiʻohiʻona, ʻoi aku ka HVC ma mua o ka hui Iapana TDK. Eia nō naʻe, e noʻonoʻo ana i nā mea e like me ka lawe ʻana i ka manawa alakaʻi a me ke kumu kūʻai e noʻonoʻo mau ai ka poʻe kūʻai aku, ʻo ka nani o nā capacitors ceramic ultra-high voltage a TDK e hāʻule maoli ana i ka HVC.

ʻO ka inoa inoa ʻekahi o ka honua no nā capacitors seramika kiʻekiʻe-voltage screw-type he Japanese Murata. I ka makahiki 2018, ma hope o ka hoʻolaha ʻana o Murata i kona hoʻopau ʻana i ka hana ʻana, ua ʻimi ka hui ʻAmelika ʻo VISHAY a me ka hui Kepani ʻo TDK e hoʻopiha i ka hakahaka o ka mākeke i waiho ʻia e Murata ma o ka hoʻopuka ʻana i nā mea paʻi a me ka helu ʻana i ka ʻike "cross-reference" ma nā pūnaewele mana o TDK.



I ka hoʻohālikelike ʻana i ka Japanese TDK a me American Vishay, ʻo HVC Capacitor kahi koho ʻoi aku ka maikaʻi loa iā Murata.

1) Hiki ke ʻike ʻia ʻo ka hoʻololi ʻana o TDK iā Murata he hoʻololi paʻakikī wale nō. No ka laʻana, hoʻohālikelike ʻia ka DHS4E4C532KT2B 15KV 5300PF N4700 o Murata e TDK me kahi mea hoʻololi like o 15KV 7000PF, Y5S. ʻIke mākou ʻoiai ke hōʻike nei nā mea Y5S o TDK i ka hana haʻahaʻa haʻahaʻa, hōʻike nā ana maoli i nā waiwai like me ka pae N4700. Eia nō naʻe, ʻaʻole hiki i ka papa 2 seramika e like me Y5S ke hana e like me ka Class 1 ceramics i nā kaiapuni kiʻekiʻe. Eia kekahi, ʻoi aku ka nui o ka mana 7000PF mai TDK no nā mea kūʻai i maʻa i ka hoʻohana ʻana i nā capacitors Murata, a ʻaʻole kūlike nā ʻāpana me nā huahana Murata kumu. Ke noʻonoʻo nei ʻo TDK he mea hana nui no ka honua, ke ʻole nā ​​​​mea kūʻai aku he poʻe kūʻai ikaika loa, ʻaʻole makemake paha ʻo TDK e hoʻolālā hou i nā mole a hoʻohana i ka pae like o nā mea seramika no nā pani Murata.



Inā hāʻawi ʻo HVC i kahi pani no kēia kumu hoʻohālike Murata, ʻo ka mea mua ʻo ka papa inoa huahana capacitor doorknob maʻamau o HVC ka mea piha loa i ka mākeke no nā huahana kīwila kiʻekiʻe-voltage, e hoʻopuni ana i nā hiʻohiʻona a pau mai nā papa kiʻekiʻe a me ka papa lua ma ka home a ma ke ao holoʻokoʻa, e like me Murata, TDK, Vishay, HVCA, a me nā mea ʻē aʻe. ʻO ka mea nui, ʻo kēlā me kēia ʻano Murata i hoʻokuʻu ʻia i ka lehulehu ma ka pūnaewele he hoʻonā mākaukau mai HVC. ʻOiai no nā capacitors Murata me nā ana i hoʻopilikino ʻia a me nā pahu metala no kekahi mau mea kūʻai nui ʻaʻole i ʻike ʻia ma ka pūnaewele (no ka laʻana, kahi capacitor 40KV 3000PF N4700 mai kahi ʻoihana radiative ma lalo o ka Sumitomo Electric o Iapana), hāʻawi ʻo HVC i kahi hopena maʻamau 1: 1 ma ka loa. kumu kūʻai haʻahaʻa. Eia kekahi, ʻo ka capacitance, tolerance, material, etc., he ʻano like me nā kikoʻī Murata mua, a ma kekahi mau hihia, ʻo HVC me ka hoʻohana ʻana i ka Class 1 "N4700" ceramics material e hoʻololi ai i ka Murata's Class 2 "Z5U" ceramics material, like loa me ʻO ka moʻolelo kahiko Kina o "The Race of the Swift Horse."（田忌赛马）
 

2) Eia kekahi, ʻoiai ʻo TDK he mea hana ʻenehana uila Iapana kaulana i ka honua, ʻaʻole ikaika loa ka kamaʻilio ʻenehana a me nā pae lawelawe o nā lālā a me nā ʻelele o TDK ma waho o Iapana e like me ko nā ʻelele o HVC. Aia kekahi mau manawa i hōʻike ʻia e kahi mea kūʻai mai kahi hui uila Kelemania i ka wā e hoʻāʻo ai me nā capacitors TDK a me HVC, ʻaʻole i hāʻawi ka luna o TDK i ke kākoʻo ʻenehana kūpono. ʻO ka ʻokoʻa, ʻo ka ʻelele Kelemania ʻo HVC, AMEC, kipa wikiwiki i nā mea kūʻai aku, hōʻoia i ka hauʻoli o ka mea kūʻai aku ma o ka kamaʻilio ʻenehana kūpono, a hōʻike i ka maʻalahi i nā hana, e waiho ana i kahi manaʻo maikaʻi i nā mea kūʻai. Ma nā ʻoihana e like me nā mea hana nui e like me nā mea hoʻololi mana, mahalo nui ʻia ke kākoʻo ʻenehana e nā mea kūʻai hope.

3) Ma hope o nā makahiki o ka hoʻoikaika ʻana, ua loaʻa i ka HVC Capacitor ka ʻike a loaʻa i nā hoʻouna nui mai nā mea kūʻai aku capacitor screw kiʻekiʻe e like me Nikon, Konica Minolta, GE Healthcare, Johnson & Johnson, Baker Hughes, a me nā mea ʻē aʻe. ʻO ka hana ʻoihana me nā mea kūʻai aku Iapana a me nā hui Fortune 500 e hōʻike ana i ka HVC Capacitor e hoʻokō i nā koi ʻenehana koʻikoʻi o nā mea kūʻai hope loa i ka ʻoihana.




I ka hōʻuluʻulu ʻana, ʻo ka HVC Capacitor kahi mea hoʻololi kūpono loa no nā capacitors screw high-voltage mai ka brand Japanese Murata i hoʻohālikelike ʻia me TDK. Hiki i nā huahana HVC ke hāʻawi aku i nā mea kūʻai aku o TDK ultra-high voltage capacitors i kahi ʻike ʻenehana ʻē aʻe.

Aia ma lalo nā hiʻohiʻona hoʻohālikelike o ka piha piha o nā capacitors screw high-voltage mai TDK a me HVC:
