He aha ka Ea Core Coil Inductor?

ʻO ka 'Air Core Coil' i kapa ʻia ʻo 'Air Cored Inductor' he ʻano o ka inductor ʻaʻole e hoʻohana i kahi kumu magnetic i hana ʻia mai kahi mea ferromagnetic e hoʻoheheʻe i kona mau wili a puni. He mana koʻikoʻi kēlā ʻano hana ʻokoʻa i ka waiwai uila a me ka hana ʻana o ka hāmeʻa, ʻoi aku hoʻi no kēlā mau noi e koi ana i ka nalowale haʻahaʻa-magnetic a me ka hana kiʻekiʻe. ʻAʻole like me nā inductors me ka ferromagnetic core, i loaʻa i ka hysteresis a i ʻole eddy-current losses, ʻaʻole i loaʻa i ka inductor air-core kēia mau poho, no laila ʻaʻole pono ke hoʻohālikelike ʻia no nā hana āpau. He mea koʻikoʻi kēia no kēlā mau noi i koʻikoʻi ka hōʻailona hōʻailona.

Ma ka hoʻomaʻamaʻa ʻana i ka ea, ua loaʻa kēia inductance i kahi Q kiʻekiʻe (ʻoi aku ka maikaʻi) - kahi ana maʻamau e hōʻike ana i ka pono o kahi inductance a me ka laulā o ka paʻa ʻana o ke alapine e hiki ai ke haʻalulu ma waena. Kūkulu ʻia kēia mau mea i kūpono loa mai ka hoʻohana pinepine ʻana, e like me nā mea ma ka RF lap, kahi e hoʻomaʻamaʻa ai i ka kānana, oscillator, a me ke kani kani. ʻAʻole hoʻohana wale ʻia ʻo Tehy i ka mea hoʻouna hoʻolaha, akā maʻamau nō hoʻi i nā eccentric o feeler, ʻo ia hoʻi nā hana ma ka wahi hana hoʻopono hoʻokele HFT (High Frequency Transceiver), kahi i hoʻopaʻa pinepine ʻia nā antenna a hiki ke hoʻopaʻa ʻia i nā hihia o kahi tuner antenna.

Eia kekahi, ʻo ka air core coil inductor ka versatility e hoʻolālā ʻia no nā noi kikoʻī, me nā ʻano like ʻole a me nā nui i hoʻohālikelike ʻia no kekahi mau kikoʻī kaapuni. ʻO ka versatility, a me kona maikaʻi i ka kiʻekiʻe-frequency a me ka hana kiʻekiʻe, he mea nui ia i ke kahua o nā ʻāpana uila, ʻoi aku hoʻi me ka koi kiʻekiʻe no ka uila kiʻekiʻe a me ka pono kiʻekiʻe. ʻOiai ʻo kēia mau pōmaikaʻi, pono e kuhikuhi ʻia ʻo nā inductors air core i hoʻopili ʻia e hāʻawi pinepine i ka inductance haʻahaʻa ma mua o kā lākou ferromagnetic inductor counterparts a ʻoi aku paha ka nui no kahi inductance i hāʻawi ʻia, hiki ke kaupalena i kā lākou hoʻohana ʻana i nā noi palena nui.
