Zvinoenderana nehunhu hweiyo yekukanganisa sosi, frequency renji, voltage uye impedance uye mamwe ma paramita uye mutoro hunhu hwezvinodiwa, kusarudzwa kwakakodzera kwemafirita, kazhinji funga:
Kune imwe, inodikanwa kuti iyo electromagnetic kupindira sefa inogona kusangana neattenuation hunhu uye kuisa kurasikirwa kwezvinodiwa zvemutoro mukati meiyo inoenderana yekushanda frequency bhendi, uye kana sefa yekumisikidza huwandu isingaite zvinodiwa, inogona kushandiswa multistage, inogona. kuwana attenuation yakakwira kupfuura nhanho imwe, akasiyana mafirita cascade, anogona kuwana yakanaka attenuation maitiro uye kurasikirwa kwekuisa mubroadband bhendi.
Chechipiri, kuti usangane nemutoro wedunhu rekushanda frequency uye kudikanwa kwekudzvanya kuwanda kwezvinodiwa, kana iyo frequency yekudzvanywa uye kuwanda kwemasaini anobatsira ari pedyo zvakanyanya, zvinodikanwa kuve neanokwira zvakanyanya frequency maitiro eiyo. Sefa, kuitira kuti isangane nekudzvanywa kweiyo yekukanganisa frequency sefa, ingobvumira kushandiswa kweanobatsira frequency chiratidzo zvinodiwa.Chechitatu, muhuwandu hunodiwa, iyo impedance yeEMI sefa RFI sefa inofanirwa kuenderana nekukanganisa sosi impedance uye mutoro unopindirana wakabatana nawo, uye kana mutoro wacho wakakwira impedance, iyo impedance yekubuda kwesefa yemagetsi inofanira kunge yakaderera kuramba, uye kana iyo magetsi kana kupindira sosi impedance yakaderera impedance, iyo inobuda impedance yesefa inofanirwa kuve yakanyanya kuramba.
Kana iyo impedance yemagetsi kana kupindira sosi impedance isingazivikanwe kana shanduko mune yakakura siyana, zvakaoma kuwana yakagadzikana yekusefa maitiro, kuti uwane iyo sefa ine yakanaka yakagadzikana yekusefa maitiro, inogona kunge iri mune yekusefa yekupinza uye kubuda, pa panguva imwe chete uyezve yakagadziriswa resistor.
Chechina, iyo sefa inofanirwa kunge iine imwe yekumanikidza kuramba, zvinoenderana nemagetsi uye kupindira sosi yeiyo yakatemerwa voltage kusarudza iyo magetsi sefa, kuitira kuti ive yakakwira yakakwana yakayerwa voltage, kuve nechokwadi chekuti zvese zvinotarisirwa mamiriro ekushanda anogona kuve akavimbika kushanda. , inogona kutsungirira kukanganiswa kwekuisa pakarepo high pressure.shanu, iyo sefa yemagetsi inobvumira pass kuti ienderane neyakayerwa ikozvino inomhanya ichienderera mudunhu.
Iyo yakakwira yakagadziriswa ikozvino ichawedzera huwandu uye huremu hweEMI sefa, uye iyo yakaderera yakagadziriswa ikozvino inoderedza kuvimbika kweEMI sefa.Nhanhatu, iyo sefa yemagetsi inofanirwa kunge iine simba rakakwana remagetsi, chimiro chakareruka, huremu huremu, saizi diki, nyore kuisa, yakachengeteka uye yakavimbika.
