1. Cov yam ntxwv ntawm cov khoom sib nqus:
Cov hlau nplaum cov ntaub ntawv tsuas yog muab faib rau cov khoom sib nqus ruaj khov thiab cov khoom sib nqus. Cov khoom siv hlau nplaum ruaj khov tseem hu ua cov ntaub ntawv sib nqus. Cov hlau nplaum tuaj yeem khaws nws lub zog ntawm cov hlau nplaum ntev ntev tom qab siv daim ntawv sib nqus, thiab nws yog tus cwj pwm ntawm qhov muaj zog co (Hc). Feem ntau nws qhov coercivity Hc≥10A4 / m. Cov khoom siv hlau nplaum loj (BH) loj yog qhov loj. Cov khoom siv mos yog cov khoom siv sib nqus uas yooj yim rau magnetize thiab demagnetize tom qab thov kev sib nqus. Lawv tsiag ntawv los ntawm kev quab yuam tsis muaj zog, thiab feem ntau lawv lub zog quab yuam Hc≤10A3 / m.
2. Plaub qhov tseem ceeb ntawm cov khoom siv hlau nplaum ruaj khov
(1) Tshaj tawm cov khoom siv hlau nplaum ntau tshaj plaws Lub siab nqus cov khoom siv hluav taws xob (BH) siab tshaj plaws yog ntsuas ntawm qhov siab tshaj plaws lub zog sib nqus khaws cia thiab muaj nyob rau ib seem ntim ntawm cov khoom sib nqus ruaj khov. (2) Lub zog sib zog ua kom muaj zog Lub zog sib zog (Hc) yog ib qho kev ntsuas ntawm cov hlau nplaum ruaj khov kho los ntawm kev cuam tshuam ntawm cov khoom sib nqus thiab tsis muaj qhov sib nqus. (3) High residual sib txawv flux ceev (Br) thiab siab residual magnetization (Mr) yog ntsuas ntawm lub zog sib nqus ntawm qhov chaw muaj zog hauv huab cua sib txawv. (4) Kev ruaj khov siab yog hais txog qhov siab ruaj khov ntawm kev cuam tshuam sab nraud ntawm lub teb chaw sib nqus, ntsuas kub, ntsuas kev co thiab lwm yam ib puag ncig.
3. Lub ntsiab tseem ceeb ntawm cov ntaub ntawv mos mos
(1) Kev quab yuam qis Hc: Nws qhia tau tias cov khoom siv hlau nplaum yog qhov yooj yim yuav tsum tau sib nqus los ntawm qhov chaw sib nqus sab nraud, tab sis kuj yooj yim raug rhuav tshem los ntawm qhov chaw sib nqus lossis lwm yam, thiab cov sib nqus poob kuj tsawg. (2) saturation siab flux ntom ceev Bs thiab siab saturation magnetization Ms: Ua li no, Rong txhob txwm tau txais qhov siab permeability thiab tsis tshua muaj lub zog co Hc, uas tseem tuaj yeem nce cov hlau nplaum flux ceev. (3) Tsis tshua muaj hlau nplaum poob thiab hluav taws xob poob: Qhov no yuav tsum muaj coercivity Hc siab thiab lub zog siab. (4) Muaj kev ruaj khov siab: nws muaj qhov ruaj khov tiv thaiv cov kev hloov hauv ib puag ncig xws li ntsuas kub thiab vibration.
Daim ntawv thov kev faib khoom ntawm cov khoom siv sib nqus hauv 5G xov tooj ntawm tes
1. Daim ntawv thov ntawm NFC cov ntaub ntawv sib nqus yog siv rau cov chaw ze tsis sib ze thiab lub teeb liab thaiv. Kev siv kev siv manganese-zinc ferrite thiab nickel-zinc ferrite
2. WPC cov khoom siv hlau nplaum yog siv rau cov wireless kis ntawm tam sim no. Ferrite sib nqus ntawv, nanocrystalline ribbon, thiab lwm yam.
3. Daim ntawv thov ntawm EMI cov ntaub ntawv sib nqus yog siv rau kev tiv thaiv thiab txhim kho ntawm lub xov tooj xov tooj kav hlau txais xov. Ferrite cov ntaub ntawv sib nqus xws li cov nplhaib sib nqus thiab cov hlaws dai.
