Pali zofunikira zosiyanasiyana za ma capacitor muzipangizo zamagetsi zolondola kwambiri, chifukwa chilichonse chomwe chimagwiritsidwa ntchito chimafuna mphamvu zamagetsi ndi kudalirika. Ma capacitor, monga zigawo zazikulu zosagwira ntchito, amachita ntchito zofunika kwambiri pakusunga mphamvu, kusefa ma signal, kukhazikika kwa magetsi, komanso kuwongolera nthawi. Kuti muwonetsetse kuti machitidwe amagetsi amagwira ntchito bwino komanso nthawi yayitali, ndikofunikira kusankha ma capacitor kutengera kufananiza kwatsatanetsatane kwa magawo ndi kusanthula kwa mawonekedwe a ntchito.
Mu zida zamagetsi zamakono zamakono zothamanga kwambiri, zipangizo zomangira pamwamba (SMDs) zakhala maziko a kapangidwe kamakono ka ma circuit. Kupatula ma capacitor, resistors, inductors, EMI filters, ndi thermistors amapanga dongosolo lofunikira la zinthu zomwe zimatsimikizira kukhazikika, magwiridwe antchito oletsa kusokonezedwa, komanso kulimba kwa nthawi yayitali m'mafakitale, magalimoto, ndi ma semiconductor.
Ma Chip resistors ndi omwe amagwiritsidwa ntchito kwambiri, omwe amapereka malire enieni a current, kugawa kwa voltage, ndi kuchepetsa chizindikiro. Ma High-precision thin-film resistors amapereka kulekerera kochepa (kotsika ngati ± 0.1%), low temperature coefficient (TCR), komanso kukhazikika kwabwino, zomwe zimapangitsa kuti akhale abwino kwambiri poyezera, kugwiritsa ntchito zida, komanso kulumikizana. Mosiyana ndi zimenezi, ma Power resistors amathandizira kufalikira kwa mphamvu zambiri ndipo amagwiritsidwa ntchito kwambiri pakuwongolera mphamvu, kuyendetsa magalimoto, ndi machitidwe oyendetsa mafakitale.
Ma Chip inductors ndi ma power inductors amachita ntchito zofunika kwambiri pakusunga mphamvu, kusefa, ndi kusintha kwa DC-DC. Ndi kukana kochepa kwa DC (DCR) ndi kuchuluka kwa mphamvu, amachepetsa bwino kutayika kwa mphamvu ndikuwonjezera magwiridwe antchito osinthira. Ma high-frequency inductors amathandizira ma radio-frequency (RF) ndi ma high speed signal circuits, kusunga umphumphu wa chizindikiro pamene akuchepetsa kusokoneza kwa magetsi.
Zigawo zoletsa EMI, kuphatikizapo mikanda ya chip, zotchinga za common-mode, ndi zosefera zotsika mtengo, zimateteza ma circuits okhudzidwa ku phokoso lakunja ndi kusokonezedwa kwamkati. Zigawozi ndizofunikira kwambiri pakuyika ma semiconductor, zamagetsi zamagalimoto, ndi zida zanzeru, komwe kutumiza kwa chizindikiro chokhazikika kumakhudza mwachindunji magwiridwe antchito ndi chitetezo cha chinthu.
Ma thermistors ndi ma varistors amapereka chitetezo chofunikira kwambiri pa kutentha kwambiri komanso pa voltage yochulukirapo. Ma thermistors a Negative temperature coefficient (NTC) amawunika kusintha kwa kutentha nthawi yeniyeni, kuteteza kutentha kwambiri m'ma module amphamvu kwambiri. Ma Varistors amayamwa mwachangu ma surge voltages, kuteteza ma chips ndi ma circuit boards ku ma voltage spikes ndi kuwonongeka kwa electrostatic.
Kusankha zigawo kuyenera kuganizira kukula kwa phukusi, magwiridwe antchito amagetsi, kulekerera chilengedwe, ndi miyezo yodalirika monga AEC-Q200 pakugwiritsa ntchito magalimoto. Ma phukusi ang'onoang'ono (0402, 0201, 01005) amathandizira kuchuluka kwa ma PCB, pomwe zigawo zolimba zimasunga kukhazikika pakatentha kwambiri, chinyezi, ndi kugwedezeka.
Pamene zamagetsi zikupitirira kusintha kukhala zochepetsera mphamvu, ma frequency apamwamba, ndi nzeru, magwiridwe antchito a chip resistors, inductors, filters, ndi zigawo zoteteza zidzakhalabe zofunika kwambiri pakupanga makina. Kusankha zigawo za SMT zapamwamba komanso zogwirizana ndikofunikira kwambiri pakukweza kudalirika kwa zinthu, kuchepetsa kuchuluka kwa kulephera, komanso kukulitsa mpikisano wonse.
