3. Electromagnetic Compatibility (EMC) kev ua kom zoo
Lub hauv paus ntsiab lus: Cov nonlinear yam ntxwv ntawm diodees tuaj yeem nqus lossis muaj kev cuam tshuam hluav taws xob, txo cov cim hluav taws xob, thiab txhim kho ove {interverre.
Txoj kev siv:
SCHOTTKY DIODE: Qw Forward Chankment poob thiab nrawm dua hloov cov yam ntxwv, haum rau EMI lim hauv siab - zaus.
Kuj tsis paub meej txog Diode: los ntawm kev kho lub capacitance muaj nuj nqis, cov zaus uas muaj peev xwm ntawm RF Circuit Court yog qhov zoo los txo lub EMI.
Cov ntaub ntawv: Ib tug ntse txuag lub cuab yeej siv schottky diodes rau kev ntsuam xyuas bluetooth (CISP 32) kom txo rau kev cuam tshuam nrog lwm cov khoom siv.
2, Daim ntawv thov tshwj xeeb ntawm diodees hauv cov khoom siv hluav taws xob hauv cov neeg siv khoom
1. Cov smartphones
Daim Ntawv Thov Qhia:
USB interface: Bidirectional TVs diode los tiv thaiv cov esd poob siab.
Lub koob yees duab module: zener Diode tiv thaiv cov duab sensor los ntawm kev hloov pauv.
RF Pem Hauv Ntej -} Xaus: Schottky Diode rau Bias Tswj Tsawg Tus Tsawg- Cov suab nrov.
Kev ntsuas dav:
Siv me me -} qhov loj me dodes ntim hauv 0201 kom txuag tau qhov chaw PCB.
Ua ke EMC simulation cov cuab yeej los txhim kho cov txheej txheem Diode thiab txo cov kav hlau txais xov nyiaj sib txuas.
2. Tablet Computer
Daim Ntawv Thov Qhia:
Lub FAIS ADAPTER Adapace: Ntau theem TVs dodes ua ke nrog GDT muaj kev tiv thaiv ntau zog.
Tso cov neeg tsav tsheb Backlight: Zener Diode cov ruaj khov LED tau tsav tsheb tam sim no thiab ncua kev pabcuam lub neej.
Kov vaj huam sib luag: ESD tiv thaiv diode array los tiv thaiv tib neeg kev cuam tshuam tib neeg.
Kev ntsuas dav:
Siv cov TV tsis tshua muaj kuab<1pF) to reduce attenuation of high-speed signals.
Txais cov txheej txheem qib ESD tiv thaiv lub tswv yim, ua ke nrog software algorithms kom ua tiav tiag {0} Kev tshuaj xyuas.
3. Ntse Cov Khoom Siv Hluav Taws Xob
Daim Ntawv Thov Qhia:
Lub plawv tus nqi sensor: ib qho hluav taws xob regulator Diode tiv thaiv cov kev nkag siab ntawm lub zog hluav taws xob cuam tshuam.
Wireless Setging module: TVs Diode txwv tsis pub muaj kev tshaj lij thaum lub sijhawm them nyiaj.
Saj zawg zog Circuit Coffuit Co Board (FPC): Ultra Me Esd Tiv Thaiv Diode Array, haum rau cov chaw me me.
Kev ntsuas dav:
Tsim kho cov diode ntim kev sib haum kom tau raws li qhov yuav tsum tau ntawm cov khoom siv hluav taws xob hloov tau.
