xov xwm

Magnetic rob muaj txawv impedance yam ntxwv ntawm txawv frequencies. Feem ntau, lub impedance yog me me ntawm tsawg zaus, thiab lub impedance nce sharply ntawm high frequencies. Qhov siab dua qhov teeb liab zaus, qhov yooj yim dua nws yog rau cov magnetic teb kom tawg tawm. Feem ntau, cov kab teeb liab tsis thaiv. Piv txwv li, lub npav CAN kuv siv tam sim no. Cov kab teeb liab no dhau los ua antennas. Lub kav hlau txais xov no tsis tu ncua tau txais ib puag ncig cov teeb liab siab. Superposition hloov lub teeb liab tiag tiag kom kis tau tus mob. Lub nplhaib sib nqus tuaj yeem hla cov cim tseem ceeb tau zoo thaum tiv thaiv cov teeb meem cuam tshuam ntau zaus.

Nyob rau hauv qhov ntau zaus, qhov inductive reactance tseem me me, thaum lub impedance loj, yog li ntawd thaum lub zog ntawm cov teeb liab siab zaus dhau los ntawm cov khoom sib nqus, nws hloov mus rau hauv tshav kub thiab tawm, uas tiv thaiv kev hla ntawm qhov siab. -frequency teeb liab thiab suppresses cuam tshuam ntawm high-frequency teeb liab. . Feem ntau qhov kev txwv ntau zaus yog cuam tshuam nrog ferrite suppression element. Feem ntau, qhov siab dua qhov sib nqus permeability, qhov qis dua qhov kev tawm tsam. Qhov loj dua qhov ntim ntawm ferrite, qhov zoo dua qhov kev tawm tsam. Thaum lub ntim tsis tas li, qhov ntev thiab nyias nyias yog ntev dua qhov luv thiab tuab. Cov nyhuv suppression yog qhov zoo, qhov me me ntawm lub zog sab hauv, qhov zoo dua qhov kev tawm tsam.

Thaum suppressing hom teeb liab cuam tshuam, koj tuaj yeem hla lub teeb liab lossis kab hluav taws xob los ntawm lub nplhaib sib nqus sib nqus tib lub sijhawm. Txhawm rau ua kom cov nyhuv, koj tuaj yeem ua ob peb symmetrical tig ntawm lub nplhaib sib nqus kom nce qhov inductance thiab txhim kho qhov nqus ntawm cov teeb liab hom. Lub teeb liab phem tsis muaj qhov cuam tshuam.

Huizhou Mingda Precise Electronics Co., Ltd. muaj cov chaw tsim khoom tshwj xeeb hauv kev tsim cov EMI los tiv thaiv kev cuam tshuam cov hlau nplaum. Peb muaj engineers nrog 20 xyoo ntawm TDK R & D thiab tsim kev paub. Peb tuaj yeem kho cov nplhaib sib nqus nrog kev ua haujlwm tshwj xeeb thiab loj raws li qhov sib txawv ntawm cov neeg siv khoom rau EMI los tiv thaiv kev cuam tshuam cov hlau nplaum. khoom.
