Kunezidingo ezahlukahlukene zama-capacitor kumadivayisi kagesi anembe kakhulu, njengoba isimo ngasinye sohlelo lokusebenza sidinga izakhiwo zikagesi ezithile kanye nokuthembeka. Ama-capacitor, njengezingxenye eziyisisekelo ezingasebenzi, adlala indima ebalulekile ekugcineni amandla, ukuhlunga isignali, ukuzinza kwamandla kagesi, kanye nokulawula isikhathi. Ukuqinisekisa ukusebenza kahle kanye nobude bezinhlelo ze-elekthronikhi, kubalulekile ukukhetha ama-capacitor ngokusekelwe ekufanisweni okuningiliziwe kwamapharamitha kanye nokuhlaziywa kwesimo sohlelo lokusebenza.
Emishinini kagesi yanamuhla enamandla amakhulu nesivinini esikhulu, amadivayisi okufaka izinto eziphezu komhlaba (ama-SMD) aseyisisekelo somklamo wesifunda wanamuhla. Ngale kwama-capacitor, ama-resistors, ama-inductor, ama-EMI filters, nama-thermistors akha uhlelo olubalulekile lwe-passive component oluqinisekisa ukuzinza, ukusebenza okulwa nokuphazamiseka, kanye nokuqina kwesikhathi eside ezinhlelweni zezimboni, zezimoto, kanye neze-semiconductor.
Ama-resistors e-Chip ayizingxenye ezisetshenziswa kakhulu, ahlinzeka ngomkhawulo wamanje oqondile, ukuhlukaniswa kwe-voltage, kanye nokunciphisa isignali. Ama-resistors e-thin-film anembile kakhulu anikeza ukubekezelela okuphansi (okuphansi njengo-±0.1%), i-coefficient yokushisa okuphansi (i-TCR), kanye nokuqina okuhle kakhulu, okwenza afaneleke kakhulu ekulinganisweni, ekusetshenzisweni kwezinsimbi, kanye nasezifundeni zokuxhumana. Ama-resistors kagesi, ngokuphambene, asekela ukusatshalaliswa kwamandla aphezulu futhi avame ukusetshenziswa ekuphathweni kwamandla, ekulawulweni kwezimoto, kanye nasezinhlelweni zokushayela zezimboni.
Ama-inductor e-chip kanye nama-inductor kagesi adlala indima ebalulekile ekugcineni amandla, ukuhlunga, kanye nokuguqulwa kwe-DC-DC. Ngokumelana okuphansi kwe-DC (DCR) kanye nomsinga wokugcwala okuphezulu, anciphisa ngempumelelo ukulahlekelwa kwamandla futhi athuthukise ukusebenza kahle kokuguqulwa. Ama-inductor e-high-frequency asekela amasekethe esignali yomsakazo (RF) kanye nesivinini esikhulu, agcina ubuqotho besignali ngenkathi enciphisa ukuphazamiseka kwe-electromagnetic.
Izingxenye zokucindezela i-EMI, okuhlanganisa ama-chip beads, ama-common-mode chokes, kanye nezihlungi ezidlula kancane, zivikela izifunda ezibucayi emsindweni wangaphandle kanye nokuphazamiseka kwangaphakathi. Lezi zingxenye zibaluleke kakhulu ekupakishweni kwe-semiconductor, kuma-electronics ezimoto, nakumadivayisi ahlakaniphile, lapho ukudluliswa kwesignali okuzinzile kuthinta ngqo ukusebenza komkhiqizo kanye nokuphepha.
Ama-thermistors nama-varistors ahlinzeka ngokuvikelwa okubalulekile kokushisa okuphezulu kanye nokwe-voltage ephezulu. Ama-thermistors e-Negative temperature coefficient (NTC) aqapha izinguquko zokushisa zesikhathi sangempela, avimbele ukushisa ngokweqile kumamojula wamandla aphezulu. Ama-varistors amunca ngokushesha ama-voltage okukhuphuka, avikele ama-chips namabhodi wesekethe ekukhuphukeni kwamandla kagesi kanye nomonakalo we-electrostatic.
Ukukhethwa kwezingxenye kumele kucabangele usayizi wephakheji, ukusebenza kukagesi, ukubekezelelana kwemvelo, kanye nezindinganiso zokuthembeka njenge-AEC-Q200 yezinhlelo zokusebenza zezimoto. Amaphakheji amancane (0402, 0201, 01005) anika amandla aphezulu e-PCB, kuyilapho izingxenye eziqinile zigcina ukuzinza ngaphansi kokushisa okuphezulu, umswakama, kanye nokudlidliza.
Njengoba izinto zobuchwepheshe ziqhubeka nokuthuthuka zibe yi-miniaturization, imvamisa ephezulu, kanye nobuhlakani, ukusebenza kwama-chip resistors, ama-inductors, izihlungi, kanye nezingxenye zokuvikela kuzohlala kunquma ekwakhiweni kwesistimu. Ukukhetha izingxenye ze-SMT ezisezingeni eliphezulu nezihambisanayo kubalulekile ekuthuthukiseni ukuthembeka komkhiqizo, ukunciphisa amazinga okuhluleka, kanye nokuthuthukisa ukuncintisana okuphelele.
