I ka ʻoihana uila e ulu wikiwiki nei i kēia lā, koʻikoʻi ka hilinaʻi o nā mea a me ka hana. Hoʻolālā ʻia ka YMIN Electronics' series of LED aluminum electrolytic capacitors no nā noi hana kiʻekiʻe ma nā wahi paʻakikī, ʻo ia hoʻi i nā kukui, nā lako mana ʻenehana, a me nā uila uila.
Nā hiʻohiʻona huahana maikaʻi loa
ʻO kā mākou alumini electrolytic capacitors, i hana ʻia me ka hoʻohana ʻana i ka ʻenehana electrolyte wai kiʻekiʻe a me nā mea kiʻekiʻe kiʻekiʻe, hāʻawi i nā hiʻohiʻona ʻokoʻa. Hoʻohana paʻa lākou ma luna o kahi ākea ākea o -25 ° C a i + 130 ° C, a loaʻa i kahi helu uila helu o 200-500V, e hālāwai ana i nā pono o nā noi kiʻekiʻe-voltage. Hoʻomalu ʻia ka hoʻomanawanui ʻana i loko o ± 20%, e hōʻoiaʻiʻo ana i ka pololei a me ka kūlike i ka hoʻolālā kaapuni.
ʻO ka mea kaulana loa ʻo kā lākou hana wela kiʻekiʻe: hāʻawi lākou i ka hana mau no 2,000 mau hola ma 130 ° C a hiki i 10,000 mau hola ma 105 ° C. ʻO kēia kūʻokoʻa kiʻekiʻe kiʻekiʻe e kūpono iā lākou no nā noi kukui LED kiʻekiʻe, e like me nā kukui alanui kiʻekiʻe, nā kukui ʻoihana, a me nā ʻōnaehana kukui ʻoihana i loko.
Nā kikoʻī ʻenehana koʻikoʻi
Hoʻokō kā mākou huahana i nā kūlana AEC-Q200 a hoʻokō ʻia ʻo RoHS, e hōʻike ana i kā mākou kūpaʻa i ka maikaʻi a me ka palekana o ke kaiapuni. He haʻahaʻa loa ka leakage, e pili ana i ka maʻamau o ≤0.02CV+10(uA), kahi ʻo C ka capacitance nominal (uF) a ʻo V ka volta helu (V). Noho ka waiwai tangent poho ma waena o 0.1-0.2 ma muli o ka volta. ʻOiai no nā huahana me ka capacitance ma mua o 1000uF, ʻo ka piʻi ʻana he 0.02 wale nō no kēlā me kēia 1000uF hou.
Hāʻawi pū nā capacitors i nā hiʻohiʻona impedance ratio maikaʻi loa, e mālama ana i kahi ratio impedance ma waena o 5-8 i loko o ke ana wela o -40 ° C a hiki i 20 ° C, e hōʻoiaʻiʻo ana i ka hana maikaʻi loa ma nā wahi haʻahaʻa haʻahaʻa. Hōʻike ka hoʻāʻo ʻana ma hope o ka ʻike ʻana i ka volta helu a me ka ripple i kēia manawa ma 130 ° C, e mau ana ka hoʻololi capacitance i loko o ± 20% o ka waiwai mua, ʻoiai ʻo ka waiwai tangent nalowale a me ka leakage o kēia manawa aia ma lalo o 200% o nā waiwai i kuhikuhi ʻia.
Nā noi ākea
Nā Keaukaha kukui LED
He kūpono loa kā mākou mau capacitors no nā lako mana hoʻokele LED, kānana pono ʻana i ka walaʻau kiʻekiʻe a hāʻawi i ka mana DC paʻa. Inā hoʻohana ʻia i nā kukui o loko a i ʻole nā kukui alanui waho, hōʻoia lākou i ka hana paʻa lōʻihi a hoʻemi i nā kumukūʻai mālama.
Pūnaehana Mana Hana Hana
I loko o ka ʻoihana lako mana hana, hiki ke hoʻohana ʻia kā mākou huahana i nā mea hana e like me ka hoʻololi ʻana i nā lako mana, nā inverters, a me nā mea hoʻololi pinepine. ʻO kā lākou mau hiʻohiʻona ESR haʻahaʻa e kōkua i ka hōʻemi ʻana i ka nalowale o ka mana a hoʻomaikaʻi i ka ʻōnaehana holoʻokoʻa.
Kaʻa uila
ʻO ka hoʻokō ʻana i nā kūlana AEC-Q200 e hiki ai i kā mākou huahana ke hoʻokō i nā koi hilinaʻi koʻikoʻi o nā uila uila a kūpono i nā noi e like me nā ʻōnaehana mana onboard, nā mana mana ECU, a me nā kukui LED.
Lako Hoolaha
Ma nā kikowaena kumu a me nā mea hana, hāʻawi kā mākou capacitors i ka kānana mana paʻa, e hōʻoiaʻiʻo ana i nā hōʻailona kamaʻilio paʻa.
Hoʻopiha i nā kikoʻī huahana
Hāʻawi mākou i kahi laina huahana piha, e uhi ana i kahi ākea o nā koho capacitance mai 2.2μF a i 68μF ma 400V. No ka laʻana, ʻo ke kumu hoʻohālike 400V/2.2μF e ana i ka 8 × 9mm, loaʻa ka impedance kiʻekiʻe o 23Ω, a me kahi ripple o kēia manawa o 144mA. ʻO ke kumu hoʻohālike 400V/68μF, ma ka ʻaoʻao ʻē aʻe, he 14.5 × 25mm, he impedance o 3.45Ω wale nō, a me kahi ripple a hiki i 1035mA. Hiki i kēia laina huahana like ʻole ke koho i nā huahana kūpono loa no kā lākou pono noi kikoʻī.
Hōʻoia maikaʻi
Loaʻa nā huahana a pau i ka paʻa paʻa a me ka hoʻāʻo ʻana i ka mālama ʻana i ka wela kiʻekiʻe. Ma hope o 1000 mau hola o ka mālama ʻana ma 105°C, hiki ke hoʻololi i ka nui o ka hoʻololi ʻana o ka huahana, ka tangent nalowale, a me ka leakage o kēia manawa e hoʻokō i nā kūlana i kuhikuhi ʻia, e hōʻoia ana i ka hilinaʻi o ka huahana no ka wā lōʻihi.
Hāʻawi pū mākou i nā kikoʻī kikoʻī a me nā coefficient hoʻoponopono wela e hoʻomaʻamaʻa i nā ʻenekinia i ka helu pololei ʻana i nā waiwai ripple o kēia manawa ma lalo o nā kūlana hana like ʻole. ʻO ka helu hoʻoponopono alapine mai ka 0.4 ma 50Hz a hiki i ka 1.0 ma 100kHz; ka helu hoʻoponopono mahana mai 2.1 ma 50°C a i 1.0 ma 105°C.
Ka hopena
Hoʻohui nā capacitors electrolytic YMIN aluminika i ka hana kiʻekiʻe, hilinaʻi kiʻekiʻe, a me ke ola lōʻihi, e hoʻolilo iā lākou i koho kūpono no nā noi e like me ke kukui LED, nā lako mana ʻenehana, a me nā uila uila. Kūpaʻa mākou i ka hāʻawi ʻana i nā mea kūʻai aku i nā huahana kiʻekiʻe a me nā lawelawe a me ka hoʻolaha pū ʻana i ka hoʻomohala ʻana i ka ʻoihana uila.
