Musiyano uripo pakati pemagineti bead inductors uye chip multilayer inductors

1. Magnetic bead inductors uye SMT laminated inductors?

Mainductors midziyo yekuchengetedza simba uye magineti bead ndiwo magetsi ekushandura (kushandisa) zvishandiso.SMT laminated inductors inonyanya kushandiswa kudzvanya kupindira kunoitwa mumagetsi emagetsi mafirita maseketi.Magnetic beads anonyanya kushandiswa mumasaini maseketi, kunyanya kune EMI.Magnetic beads anoshandiswa kutora masaini eUHF.Semuyenzaniso, mamwe nhepfenyuro dzeredhiyo, nhanho-yakakiyiwa zvishwe, oscillator maseketi uye Ultra-yakakwirira frequency memory maseketi (DDR, SDRAM, RAMBUS, nezvimwewo) zvese zvinoda kuwedzera magineti mabhedhi kune chikamu chekuisa simba.SMD inductor imhando yesimba rekuchengetedza simba, iro rinoshandiswa muLC oscillator circuit, yepakati uye yakaderera frequency sefa redunhu, etc. Yayo frequency yekushandisa haina kashoma kudarika 50MHz.

2. Ndezvipi zvakanakira magineti bead inductors mumatunhu maitiro?
Magnetic bead inductors anoshandiswa kutora masaini e-ultra-high frequency, senge mamwe eredhiyo frequency maseketi, nhanho-yakakiyiwa zvishwe, oscillator maseketi, anosanganisira ekupedzisira-akakwira frequency memory maseketi (DDR SDRAM, RAMBUS, nezvimwewo) Rudzi urwu rwekuchengetedza simba chinhu. inoshandiswa muLC oscillation circuit, yepakati uye yakaderera frequency filter circuit, uye kushandiswa kwayo frequency renji kashoma kudarika 50MHZ isiriyo.Iyo yepasi yekubatanidza inowanzo shandisa inductor, iyo simba yekubatanidza inoshandisawo inductor, uye magineti bead inoshandiswa pamutsetse wechiratidzo?Asi muchokwadi, magineti mabedhi anofanirawo kukwanisa kutora kukanganiswa kwepamusoro-frequency, handiti?Uye iyo inductance yeiyo inductance mushure meiyo yakakwira frequency resonance haigone kuita basa….
Magnetic Bead Inductance
3. Zviri nani sei iyo chip inductance pane iyo magnetic bead inductance?

1. Laminated inductance:

Iyo zvakare ine yakanaka magineti shielding, yakakwirira sintering density, uye yakanaka mechani simba, kana ichienzaniswa nemhepo inductance: diki saizi, iyo inoenderana neiyo miniaturization yedunhu, yakavharwa magineti yedunhu, haizokanganise zvikamu zvakatenderedza, uye haizokanganisike. nezvikamu zvakapoteredza Inokodzera kuiswa kwepamusoro-density yezvikamu;iyo laminated integrated structure ine yakakwirira kuvimbika, yakanaka kupisa kupisa, yakanaka solderability, uye yakajairwa chimiro, inokodzera otomatiki pamusoro pekugadzirwa kwegomo.Izvo zvakashata ndezvekuti chiyero chakakodzera chakaderera, mutengo wakakwira, inductance idiki, uye kukosha kweQ idiki.Kazhinji kutaura, iyo multilayer inductor haigone kuona mutsara, iyo multilayer inductor ine yakanaka yekupisa kupisa, uye kukosha kweESR idiki.Yakawanda sei iyo inductor magineti bead?Unogona kutibvunza nezve zvakatemwa zvauri kufarira!

2. Zvakanakira zveSMD laminated inductors zvakasiyana kubva kune mamwe ma inductors:
A. Saizi diki.
B. Yakanakisa solderability uye solder resistance, yakakodzera kuyerera solder uye reflow soldering.
C. Dunhu rakavharwa, hapana kupindirana, kunokodzera kuiswa kwepamusoro-density.
D. Isina-directional, yakamisikidzwa kutaridzika kweotomatiki chigamba mounting.
