Ferrite yog cov khoom siv hlau nplaum uas tsis yog xim hlau, hais txog nws cov txheej txheem tsim khoom yog tsim los ntawm ferric oxide thiab lwm yam hlau oxide npaj thiab sintering, nws cov txheeb ze permeability tuaj yeem ncav cuag ntau txhiab, qhov kev tiv thaiv yog 1011 npaug ntawm cov hlau, eddy tam sim no poob yog me me, haum rau zus tau tej cov high-frequency electromagnetic li. Tam sim no nws yog cov khoom siv hlau nplaum uas tsis yog xim hlau uas siv dav hauv kev ua haujlwm siab tsis muaj zog tam sim no.
Thiab muaj ntau hom ferrite, cov hlau nplaum ruaj khov ferrite kuj yog cov khoom siv feem ntau, feem ntau vim nws tuaj yeem khaws cov khoom sib nqus muaj zog rau lub sijhawm ntev, tuaj yeem siv tau ntev thiab tsim cov hlau nplaum, uas yog vim li cas. nws yog hu ua cov hlau nplaum ruaj khov ferrite.
Ferrite daim ntawv yog ib zaj duab xis sib nqus siv rau NFC kav hlau txais xov los tiv thaiv hlau thaiv kev cuam tshuam thiab txhim kho qhov rhiab heev ntawm induction teeb liab txais tos. 13.56MHZ kav hlau txais xov Ferrite daim ntawv / zaj duab xis yog ib hom kub sintered ferrite khoom. Hauv NFC kev them nyiaj xov tooj ntawm tes thiab lwm yam khoom siv tes tuav, lub luag haujlwm tseem ceeb ntawm cov ntawv hluav taws xob yog los txo qhov nqus ntawm cov ntaub ntawv hlau mus rau qhov chaw sib nqus ntawm cov teeb liab. Nyob rau tib lub sij hawm, ferrite zaj duab xis nws tus kheej yog ib yam ntawm high-temperature sintered ferrite cov ntaub ntawv, uas yuav ua tau zoo nce lub induction nrug los ntawm kev ua kom cov magnetic teb siv.
RFID|NFC tsis kam ferrite daim hlau cov ntaub ntawv yog ib hom kev ua haujlwm sib xyaw cov ntaub ntawv los nqus cov hluav taws xob tsis zoo yog qhov tseem ceeb rau, tshem tawm cov thaiv hluav taws xob hluav taws xob yoj rov qab mus rau hauv lub cev kab noj hniav, txo cov suab nrov cuam tshuam nrog lawv tus kheej cov cuab yeej, tseem tiv thaiv kev cuam tshuam thiab electromagnetic. hluav taws xob nyob ib puag ncig cov cuab yeej siv thiab cov neeg ua haujlwm puas tsuaj, yog ib hom kev tshem tawm ntawm cov pa phem ntawm electromagnetic.
Cov tuab tuab ntawm cov ntawv ferrite suav nrog: {{0}}}08mm 0.1mm {{10}}.2mm 0.3mmNFC ferrite ntawv ntawm no, sib nqus hais txog mus rau daim ntawv sib nqus hloov tau, tsis yog-sintered ferrite nyuaj hlau nplaum, nws ib sab ntawm lub nraub qaum glial mos, cov khoom du thiab ultra-thin thickness ntawm 0.15mm ~ 0.5mm, NFC ferrite sib nqus daim ntawv ntawm 13.56MHz electromagnetic yoj zaus tuaj yeem nce. rau 35 permeability. Lub luag haujlwm ntawm NFC cov ntawv hlau nplaum hauv cov khoom siv NFC yog kwv yees li ob, ib qho yog cais cov hlau los tiv thaiv kev sib txuas lus thiab cov tawv nqaij ntawm cov hlau tsis muaj zog electromagnetic, ob yog ua kom cov hlau nplaum "zoo zog" (magnetic field zog) ntawm Reader thiab Transponder. cov tshuaj tiv thaiv rhiab heev, nyeem ntawv nrug.
