Inductors ya SMD ni iki? Bakoreshwa iki? Benshi muribo rwose ntibasobanutse neza. Umwanditsi mukuru wa BIG akurikira azaguha intangiriro irambuye:
Indimu ya SMD hejuru yubushakashatsi bwimbaraga nyinshi. Ifite ibiranga miniaturizasiya, ubuziranenge bwo hejuru, kubika ingufu nyinshi no kurwanya bike. Ahanini ikoreshwa mubibaho byerekana mudasobwa, mudasobwa ya ikaye, porogaramu yo kwibuka ya pulse, hamwe na DC-DC.
Hariho ubwoko 4 bwindimu ya chip: chip-firime yoroheje, ikozwe, insinga-igikomere hamwe nindindira nyinshi. Ubwoko bubiri bwinsinga-igikomere nubwoko bwa laminated burakoreshwa. Iyambere nigicuruzwa cya miniaturizasiya ya inductors gakondo; icya nyuma gikozwe hifashishijwe tekinoroji yo gucapa ibyiciro byinshi hamwe na tekinoroji yo kubyara. Ijwi ni rito ugereranije n'iry'icyuma gikomeretsa chip. Nibicuruzwa byingenzi byatejwe imbere murwego rwibigize inductive.
Indangantego ya chip chip inductors ifite ibiranga kugumya Q hejuru, hejuru cyane, guhagarara neza hamwe nubunini buto muri microwave yumurongo. Imbere ya electrode yimbere yibanze kumurongo umwe, kandi gukwirakwiza magnetiki yumurima byibanze, bishobora kwemeza ko ibipimo byibikoresho nyuma yo kwishyiriraho bidahinduka cyane, kandi bikerekana ibimenyetso byiza biranga hejuru ya 100MHz.
Ikiranga indipo ziboheye ni uko inductance yubunini bwa 1MHz ari nini kuruta izindi inductor za chip, ntoya mubunini, kandi byoroshye kuyishyira kuri substrate. Ikoreshwa nka miniature ya magnetiki yo gutunganya ingufu.
Ibiranga indangantego ya chip-ibikomere ni intera nini ya inductance (mH ～ H), inductance yukuri, igihombo gito (Q nini), nini yemerwa nubu, imbaraga zikomeye zo gukora umurage, ubworoherane, nigiciro gito, ariko ibibi ni ko bigarukira muri miniaturizasi. Ceramic core winding ubwoko bwa chip inductor irashobora kugumana inductance ihamye hamwe nagaciro keza cyane Q mugihe kinini cyane, bityo ifata umwanya mumuzunguruko mwinshi.
Inductors zegeranye zifite imiterere ya magnetiki ikingira, ubwinshi bwicyaha, nimbaraga nziza zubukanishi. Ingaruka ni igipimo gito cyo gutambuka, igiciro kinini, inductance nto, na Q agaciro gake. Ugereranije n’indobanure zikomeretsa insinga, guteranya bifite ibyiza byinshi: ingano ntoya, ifasha miniaturizasi yumuzunguruko, uruziga rukuruzi rwa magneti, ntiruzabangamira ibice bikikije, kandi ntiruzabangikanywa n’ibice bituranye, bifitiye akamaro Ibice Byinshi -ubwinshi bwibikoresho; imiterere ihuriweho, kwizerwa cyane; kurwanya ubushyuhe bwiza no kugurishwa; imiterere isanzwe, ikwiranye nubushakashatsi bwikora bwikora.
