ʻO nā inductors mana SMD kekahi o nā pale aniani uranium metala. Hoʻohana pinepine ʻia ka inductance mode maʻamau, ʻike ʻia hoʻi ma ke ʻano kuʻi maʻamau, e kānana i nā hōʻailona hoʻopilikia electromagnetic mode maʻamau i nā lako mana hoʻololi kamepiula. I ka hoʻolālā ʻana o ka papa kaapuni, hana pū ka mea hoʻohui i ke ʻano maʻamau ma ke ʻano he kānana EMI e kāohi i ka nalu electromagnetic i hana ʻia e ka laina hōʻailona kiʻekiʻe mai ka hoʻomālamalama ʻana i waho. He mea pale ia i hana ʻia me ka hui ʻana o ka pauka metala a me ka pauka aniani uranium, i paʻi ʻia i ka pale ma luna o ka mana SMD mana kiʻekiʻe ma kahi substrate. Maikaʻi wettability, kiʻekiʻe wela kū'ē, haʻahaʻa wela coefficient. He mea maʻamau ka hoʻohana ʻana i ka ʻenehana hui nominal, a ua ʻoi aku ka nui o nā huahana uila i hōʻuluʻulu ʻia e SMT ma mua o 90%. ua komo koʻu ʻāina i nā mākau SMT mai ka makahiki 1980. Me ka hoʻomohala ʻana i nā mea hana SMT liʻiliʻi, ua hoʻonui ʻia ka nui o ka hoʻohana ʻana i nā kāʻei SMT. Hoʻohana ka mokulele, aerospace, instrumentation, mīkini mea hana a me nā ʻāpana ʻē aʻe i ka SMT e hana i nā ʻāpana liʻiliʻi o nā huahana uila a i ʻole nā ​​ʻāpana.

Ua kapa ʻia ʻo Resistors he resistors i ke ola o kēlā me kēia lā. ʻO kahi mea palena i kēia manawa i hoʻopili ʻia i kahi pale i loko o kahi kaapuni. He waiwai paʻa ko ka resistor o nā pine ʻelua a hoʻohana ʻia e kaupalena i ke kahe o kēia manawa ma ka lālā i pili ai. ʻO ke kūpaʻa ʻaʻole hiki ke hoʻololi ʻia ka waiwai kūʻē i kapa ʻia he kūpaʻa paʻa. Kapa ʻia ka poʻe me ke kūpaʻa ʻano like ʻole he potentiometers a i ʻole nā ​​​​kuʻekuʻe loli. ʻO ke kūpaʻa virtual he laina laina, ʻo ia hoʻi, ʻo ka transient current ma o ke kūpaʻa e like me ka volta transient i noi ʻia. Palekana hoʻololi no ka mea hoʻokaʻawale uila. Hoʻokahi a ʻelua paha mea hoʻopili metala hiki ke hoʻoneʻe ʻia e kaomi paʻa i ka pale pale i ʻike ʻia. ʻO ke kūlana pili e hoʻoholo i ke kū'ē ma waena o kēlā me kēia hopena o ka pale a me ka pilina.

Nā hiʻohiʻona o nā huahana SMD power inductor
ʻO ka liʻiliʻi liʻiliʻi a me ke kaumaha māmā; · He kūpono no ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe nalu; · Hiki ke ikaika a paʻa ke kaʻa; · ʻO ke kumu kūʻai haʻahaʻa haʻahaʻa, hoʻohālikelike me nā mea hoʻokomo ikaika; · Ka ikaika mechanical kiʻekiʻe a me ke alapine kiʻekiʻe. I mea e pale aku ai i nā uea, nā puka lou a me nā coils mai ke kahua magnetic o waho a hōʻemi i ka hopena interference o ke kahua electromagnetic i hana ʻia e ke kaapuni ma nā ʻāpana ʻē aʻe, hoʻohana pinepine ʻia ka pale magnetic a i ʻole ka pale electromagnetic.
He aha nā mea i hana ʻia me nā inductors mana SMD?
Hoʻokaʻawale ʻia nā resistors SMT mai nā ʻikepili aʻe:
ʻO ka mea kumu he alumina, a ʻo ka ʻikepili kūʻē he ruthenium oxide
1. Papahana
2. Paʻi kū'ē
3. E haʻi mai i ka ʻike
4. ʻIke alakaʻi maikaʻi a me ka ʻike alakaʻi ʻaoʻao
5. Ka malama mua o ke aniani G16. ʻO ka mālama lua o ke aniani G27.
