He aha nā hiʻohiʻona o ka inductor i hoʻohui ʻia? A laila, e kaʻana like ʻo BIG iā ʻoe:

ʻO nā koʻokoʻo magnetic a me nā koʻokoʻo mākēneki Manaʻo ʻia he kūpono a hoʻohana i nā mea e like me ka nickel-zinc-iron oxygen gas (NX series) a i ʻole manganese-zinc-iron oxygen gas (MX series). He ʻano "I", he ʻano cylindrical, he ʻano pāpale, a he "E". ʻO nā ʻano like ʻole e like me "ke ʻano, ke ʻano ipu, a pēlā aku."

　　Hoʻohui ka uhi pale i kahi uhi pale metala (e like me ka vibration coil o kahi lekiō transistor, a me nā mea ʻē aʻe) e pale ai i ke kahua magnetic i hana ʻia e kahi inductor liʻiliʻi i loko o ke keʻena mai ka hoʻopilikia ʻana i ke keʻena maʻamau o nā kaapuni a me nā mea ʻē aʻe. ʻO ka hoʻohana ʻana i nā inductors pale i manaʻo ʻia he kūpono e hoʻonui i ka pōʻino o ka coil a hoʻemi i ka waiwai Q.

　　ʻO ka mea hoʻopili mea he ʻano o ka inductor (e like me ka code color inductor, color ring inductor, etc.) ma hope o ka wili ʻana, hoʻopaʻa paʻa ʻia ka coil a me ka magnetic core me ka mea hoʻopili. E like me ka mea i manaʻo ʻia he kūpono, hoʻohana ʻia nā molecular compound plastics a i ʻole nā ​​resin epoxy kūlohelohe.

ʻO kahi inductor paʻa nui a i ʻole inductor hiki ke hoʻololi ʻia (e like me ka vibrating coil, choke, etc.), ʻo ka hapa nui o lākou he mau uwea metala (a i ʻole nā ​​kaula uhi uhi ʻia) a puni nā iwi pā, a laila nā cores magnetic a i ʻole nā ​​​​kopa keleawe , Iron core, etc. hoʻokomo ʻia i loko o ka lua o loko o ka iwi pā e hoʻonui ai i kona inductance.

ʻAʻole pono nā inductors air-core (i kapa ʻia hoʻi i waho o ke kino a i ʻole ea-core coils, ka hapa nui i hoʻohana ʻia i nā kaapuni kiʻekiʻe) ʻaʻole pono i nā cores magnetic, iwi iwi, a me nā uhi pale, a me nā mea ʻē aʻe. kŘkohu a laila wehe 'ia mai ke kŘkohu hana, a ho'ohuli 'ia ka wili E mālama i kahi mamao ma waena o lākou.

　　ʻO ka wili o kahi inductor i hoʻohui ʻia e pili ana i kahi hoʻonohonoho o nā coils me nā hana kikoʻī, ʻo ia ka ʻāpana kumu o ka inductor. Loaʻa nā wili hoʻokahi-layer a me multi-layer. ʻElua mau ala no ka wili ʻana hoʻokahi: ka wili ʻana; ʻO nā wiliwili multilayer e pili ana i ka wili palahalaha papa, ka wili maʻamau, a me ka wili meli.
