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 hawewe electromagnetic i hana ʻia e ka laina hōʻailona kiʻekiʻe mai ka hoʻomālamalama ʻana i waho.He mea pale 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.ʻO ka mokulele, ka aerospace, ka mea kani, nā mea hana mīkini a me nā ʻāpana ʻē aʻe e hoʻohana i ka SMT e hana i nā ʻāpana liʻiliʻi o nā huahana uila a i ʻole 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 kūlike me ka volta transient i noi ʻia.Palekana hoʻololi no ka mea hoʻokaʻawale uila.Hoʻokahi a ʻelua paha mea hoʻopili metala hoʻoneʻe 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 ka kaapuni ma nā ʻāpana ʻē aʻe, ua hoʻohana pinepine ʻia nā ʻano hana pale magnetic a i ʻole electromagnetic.
He aha nā mea i hana ʻia me nā inductors mana SMD?
Hoʻokaʻawale ʻia nā resistors SMT mai nā ʻikepili aʻe:
