Loaʻa i nā ʻano impedance ʻokoʻa ka Magnetic rob ma nā alapine like ʻole. ʻO ka maʻamau, liʻiliʻi loa ka impedance i nā alapine haʻahaʻa, a piʻi nui ka impedance i nā alapine kiʻekiʻe. ʻOi aku ke kiʻekiʻe o ke alapine hōʻailona, ​​ʻoi aku ka maʻalahi o ke kahua magnetic e hoʻomālamalama i waho. ʻO ka maʻamau, ʻaʻole pale ʻia nā laina hōʻailona. No ka laʻana, ʻo ka pahi CAN aʻu e hoʻohana nei i kēia manawa. Lilo kēia mau laina hōʻailona i nā antenna. Loaʻa mau kēia antenna i nā hōʻailona alapine kiʻekiʻe. Hoʻololi ʻo Superposition i ka hōʻailona maoli e hoʻouna ʻia. Hiki i ke apo magnetic ke hele maikaʻi i nā hōʻailona pono i ka wā e kāohi ana i nā hōʻailona hoʻopilikia alapine kiʻekiʻe.

Ma ke alapine kiʻekiʻe, ka inductive reactance noho liʻiliʻi, oiai ka impedance nui, no laila, i ka wa i ka ikehu o ka kiʻekiʻe-frequency hōʻailona hele ma o ka magnetic mea, ua hoohuliia mai i ka wela a me ka emitted, e pale aku i ka hele ana o ka kiʻekiʻe. -frequency hōʻailona a hoʻopaʻa i ka hoʻopilikia o ka hōʻailona kiʻekiʻe. . ʻO ka mea maʻamau e pili ana ke alapine hoʻopau i ka mea hoʻopau ferrite. ʻO ka maʻamau, ʻoi aku ka kiʻekiʻe o ka magnetic permeability, ʻoi aku ka haʻahaʻa o ke alapine hoʻopau. ʻO ka nui o ka nui o ka ferrite, ʻoi aku ka maikaʻi o ka hopena suppression. Ke mau ka leo, ʻoi aku ka lōʻihi a me ka lahilahi ma mua o ka pōkole a me ka mānoanoa. He maikaʻi ka hopena hoʻopau, ʻoi aku ka liʻiliʻi o ka ikaika o loko, ʻoi aku ka maikaʻi o ka hopena hoʻopau.

I ka wā e kāohi ai i ka hoʻopilikia ʻana i ka hōʻailona maʻamau, hiki iā ʻoe ke hoʻohele i ka hōʻailona a i ʻole laina mana ma o ke apo magnetic flat i ka manawa like. I mea e hoʻonui ai i ka hopena, hiki iā ʻoe ke hana i kekahi mau hulina symmetrical i ke apo magnetic e hoʻonui i ka inductance a hoʻonui i ka hopena absorption o ka hōʻailona mode maʻamau. ʻAʻohe hopena o ka hōʻailona maikaʻi ʻole.

He mea hana kūikawā ko Huizhou Mingda Precise Electronics Co., Ltd. i ka hana ʻana i nā apo magnetic anti-interference EMI. Loaʻa iā mākou nā ʻenehana me 20 mau makahiki o TDK R&D a me ka ʻike hoʻolālā. Hiki iā mākou ke hana i nā apo magnetic me ka hana kūikawā a me ka nui e like me nā pono like ʻole o nā mea kūʻai aku no ka EMI anti-interference magnetic rings. huahana.
