Kusiyana pakati pa maginito a maginito a bead ndi ma chip multilayer inductors

1. Magnetic bead inductors ndi SMT laminated inductors?

Ma inductors ndi zida zosungira mphamvu ndipo mikanda ya maginito ndi zida zosinthira mphamvu (zakudya).SMT laminated inductors amagwiritsidwa ntchito makamaka kupondereza kusokoneza komwe kumachitika mumayendedwe amagetsi.Mikanda ya maginito imagwiritsidwa ntchito kwambiri pamayendedwe azizindikiro, makamaka a EMI.Mikanda yamaginito imagwiritsidwa ntchito kuyamwa ma siginecha a UHF.Mwachitsanzo, ma frequency ma frequency a wailesi, malupu otsekedwa ndi gawo, ma oscillator ndi ma ultra-high frequency memory circuits (DDR, SDRAM, RAMBUS, etc.) onse amafunika kuwonjezera mikanda ya maginito ku gawo lolowetsa mphamvu.SMD inductor ndi mtundu wa mphamvu yosungirako chinthu, amene ntchito LC oscillator dera, sing'anga ndi otsika pafupipafupi fyuluta dera, etc. ake ntchito pafupipafupi osiyanasiyana kawirikawiri upambana 50MHz.

2. Kodi ubwino wa maginito bead inductors mu mawonekedwe a dera ndi chiyani?
Magnetic mikanda inductors amagwiritsidwa ntchito kuyamwa ma frequency apamwamba kwambiri, monga ma frequency ma frequency a wailesi, malupu otsekedwa ndi gawo, ma oscillator ma circuits, kuphatikiza ma ultra-high frequency memory circuits (DDR SDRAM, RAMBUS, etc.) amagwiritsidwa ntchito mu LC oscillation circuit, sing'anga ndi otsika pafupipafupi fyuluta dera, ndi ntchito yake pafupipafupi osiyanasiyana kawirikawiri kuposa 50MHZ zolakwika.Kulumikizana kwapansi nthawi zambiri kumagwiritsa ntchito inductor, kulumikizidwa kwamagetsi kumagwiritsanso ntchito inductor, ndipo mkanda wa maginito umagwiritsidwa ntchito pamzere wamaginito?Koma m'malo mwake, mikanda ya maginito iyeneranso kuyamwa kusokoneza kwanthawi yayitali, sichoncho?Ndipo inductance wa inductance pambuyo mkulu pafupipafupi resonance sangakhale ndi mbali….

3. Kodi chip inductance ndiyabwino bwanji kuposa maginito a mkanda?

1. Laminated inductance:

Ilinso ndi chitetezo chabwino cha maginito, kachulukidwe kakang'ono ka sintering, ndi mphamvu yabwino yamakina, poyerekeza ndi ma inductance: kukula kwakung'ono, komwe kumathandizira kuti miniaturization ya dera, kutsekedwa kwa maginito, sikungasokoneze zigawo zozungulira, ndipo sizidzakhudzidwa. ndi zigawo zozungulira Zimathandizira kuyika kwapamwamba kwambiri kwa zigawo;kapangidwe ka laminated Integrated ali ndi kudalirika kwambiri, kukana kutentha kwabwino, solderability wabwino, ndi mawonekedwe okhazikika, oyenera kupanga zodziwikiratu padziko lapansi.Choyipa ndichakuti mtengo woyenerera ndi wotsika, mtengo wake ndi wokwera, inductance ndi yaying'ono, ndipo mtengo wa Q ndi wocheperako.Nthawi zambiri, makina opangira ma multilayer sangathe kuwona mzere, makina opangira ma multilayer ali ndi kutentha kwabwino, ndipo mtengo wa ESR ndi wocheperako.Kodi mikanda ya maginito inductor ndi yochuluka bwanji?Mutha kutifunsa za zomwe mukufuna!

2. Ubwino wa SMD laminated inductors ndi wosiyana ndi ma inductors ena:
A. Kukula kochepa.
B. Kusungunuka kwabwino kwambiri komanso kukana kwa solder, koyenera kuti muwotchere ndi kutulutsanso.
C. Dera lotsekedwa, palibe kusokonezana, koyenera kuyika kwapamwamba kwambiri.
D. Maonekedwe osalunjika, okhazikika kuti aziyika zigamba zokha.
