Chii chinonzi SMD inductors? Vanoshandisirwa chii? Vazhinji vavo havanyatsonzwisisike. Iyo inotevera BIG mupepeti inokupa yakadzama sumo:
SMD inductors pamusoro pegomo repamusoro-simba inductors. Iyo ine hunhu hwe miniaturization, yemhando yepamusoro, yakakwirira simba rekuchengetedza uye kushomeka kushomeka. Inonyanya kushandiswa mumabhodhi ekuratidzira komputa, makomputa emabhuku, pulse memory programming, uye DC-DC converters.
Kune 4 mhando dze chip inductors: yakaonda-firimu chip, yakarukwa, waya-ronda uye multilayer inductors. Mhando mbiri dzewaya-maronda mhando uye laminated mhando inowanzoshandiswa. Iyo yekutanga chigadzirwa che miniaturization yetsika waya-maronda inductors; iyo yekupedzisira inogadzirwa uchishandisa multi-layer kudhinda tekinoroji uye laminated kugadzira tekinoroji. Vhoriyamu idiki pane yewaya-ronda chip inductors. Icho chinhu chakakosha chigadzirwa chakagadzirwa mumunda we inductive components.
Thin-film chip chip inductors vane hunhu hwekuchengetedza yakakwira Q, yakakwira chaiyo, kugadzikana kwepamusoro uye diki diki mumicrowave frequency band. Iwo maelectrode emukati anonangidzirwa pane imwechete layer, uye iyo magineti yekugovera yakatarisana, iyo inogona kuve nechokwadi chekuti mudziyo paramita mushure mekukwira haushanduke zvakanyanya, uye inoratidza yakanaka frequency maitiro pamusoro pe100MHz.
Hunhu hweyakarukwa chip inductors ndeyekuti iyo unit vhoriyamu inductance pa1MHz yakakura kupfuura mamwe chip inductors, idiki muhukuru, uye nyore kuisa pane substrate. Inoshandiswa sediki magineti chikamu chekugadzirisa simba.
Hunhu hwewaya-ronda chip inductors hwakasiyana-siyana inductance (mH～H), yakakwira inductance kurongeka, kurasikirwa kwakaderera (huru Q), yakakura inotenderwa ikozvino, yakasimba yekugadzira nzira yekugara nhaka, nyore, uye yakaderera mutengo, asi iyo yakashata ndeye kuti inogumira mune imwe miniaturization. Iyo ceramic core winding type chip inductor inogona kuchengetedza yakagadzikana inductance uye yakaringana yakakwira Q kukosha pane yakakwira frequency, saka inotora nzvimbo muyepamusoro-frequency wedunhu.
Akaturikidzana inductors ane yakanaka magineti ekudzivirira zvivakwa, yakakwira sintering density, uye yakanaka mechanic simba. Izvo zvisingabatsiri ndero yakaderera yekupasa, mutengo wakakwira, diki inductance, uye yakaderera Q kukosha. Kuenzaniswa newaya ronda chip inductors, stacking ine zvakawanda zvakanakira: diki saizi, iyo inobatsira kune miniaturization yedunhu, yakavharwa magineti wedunhu, haizokanganise zvikamu zvakapoteredza, uye haizokanganiswi nezvikamu zvevavakidzani, izvo zvinobatsira kune zvikamu High. -density kuiswa kwemidziyo; chimiro chakabatanidzwa, kuvimbika kwepamusoro; zvakanaka kupisa kusagadzikana uye solderability; chimiro chenguva dzose, chakakodzera automated surface mounting production.
