Kukho iimfuno ezahlukeneyo zee-capacitors kwizixhobo ze-elektroniki ezichanekileyo, njengoko imeko nganye yesicelo ifuna iipropati ezithile zombane kunye nokuthembeka. Ii-capacitors, njengezinto eziphambili ezingasebenziyo, zidlala indima ebalulekileyo ekugcineni amandla, ukucoca isignali, ukuzinzisa i-voltage, kunye nokulawula ixesha. Ukuqinisekisa ukusebenza kakuhle kunye nobude beenkqubo ze-elektroniki, kubalulekile ukukhetha ii-capacitors ngokusekelwe ekufanisweni kweeparamitha ezineenkcukacha kunye nohlalutyo lwemeko yesicelo.
Kwizixhobo ze-elektroniki ezixineneyo nezikhawulezayo zanamhlanje, izixhobo zokufaka umphezulu (ii-SMD) ziye zaba sisiseko soyilo lwesekethe yanamhlanje. Ngaphaya kwee-capacitors, ii-resistor, ii-inductors, ii-EMI filters, kunye nee-thermistors zenza inkqubo yendalo yecandelo elingasebenziyo eliqinisekisa uzinzo, ukusebenza okuchasene nokuphazamiseka, kunye nokuqina kwexesha elide kwizicelo zoshishino, iimoto, kunye nee-semiconductor.
Ii-resistors ze-Chip zezona zinto zisetyenziswa kakhulu, zibonelela ngomda ochanekileyo wamandla, ukwahlulwa kwe-voltage, kunye nokuncitshiswa kwesignali. Ii-resistors ze-thin-film ezichanekileyo kakhulu zibonelela ngokunyamezela okuphantsi (okuphantsi njenge-±0.1%), i-low temperature coefficient (TCR), kunye nozinzo oluhle kakhulu, okwenza ukuba zilungele ukulinganisa, izixhobo, kunye neesekethe zonxibelelwano. Ii-resistors zamandla, ngokwahlukileyo, zixhasa ukusasazwa kwamandla aphezulu kwaye zisetyenziswa kakhulu kulawulo lwamandla, ulawulo lweemoto, kunye neenkqubo zokuqhuba imboni.
Ii-chip inductors kunye nee-power inductors zidlala indima ebalulekileyo ekugcineni amandla, ukucoca, kunye nokuguqulwa kwe-DC-DC. Ngokumelana okuphantsi kwe-DC (DCR) kunye nomsinga ophezulu wokugcwala, zinciphisa ngempumelelo ukulahleka kwamandla kwaye ziphucula ukusebenza kakuhle kokuguqulwa. Ii-high-frequency inductors zixhasa iisekethe zesignali zerediyo (RF) kunye nesantya esiphezulu, zigcina ukuthembeka kwesignali ngelixa zinciphisa ukuphazamiseka kwe-electromagnetic.
Izinto ezithintela i-EMI, kuquka ii-chip beads, ii-common-mode chokes, kunye nezihluzi ezisebenzisa i-low-pass, zikhusela iisekethe ezibuthathaka kwingxolo yangaphandle kunye nokuphazamiseka kwangaphakathi. Ezi zinto zibaluleke kakhulu ekupakishweni kwe-semiconductor, kwii-elektroniki zeemoto, nakwizixhobo ezikrelekrele, apho ukuhanjiswa kwesignali okuzinzileyo kuchaphazela ngokuthe ngqo ukusebenza kwemveliso kunye nokhuseleko.
Ii-thermistors kunye nee-varistors zibonelela ngokhuseleko olubalulekileyo lobushushu obugqithisileyo kunye nobushushu obugqithisileyo. Ii-thermistors ze-Negative temperature coefficient (NTC) zijonga utshintsho lobushushu ngexesha langempela, zithintela ubushushu obugqithisileyo kwiimodyuli zamandla aphezulu. Ii-varistors zifunxa ngokukhawuleza ii-surge voltages, zikhusela ii-chips kunye neebhodi zesekethe kwi-voltage spikes kunye nomonakalo we-electrostatic.
Ukukhethwa kwecandelo kufuneka kuqwalasele ubungakanani bephakheji, ukusebenza kombane, ukunyamezelana kokusingqongileyo, kunye nemigangatho yokuthembeka efana ne-AEC-Q200 kwizicelo zeemoto. Iiphakheji ezincinci (0402, 0201, 01005) zivumela uxinano oluphezulu lwe-PCB, ngelixa izixhobo eziqinileyo zigcina uzinzo phantsi kobushushu obuphezulu, ukufuma, kunye nokungcangcazela.
Njengoko izixhobo ze-elektroniki ziqhubeka nokutshintsha zibe yi-miniaturization, i-frequency ephezulu, kunye nobukrelekrele, ukusebenza kwee-chip resistors, ii-inductors, izihluzi, kunye nezixhobo zokukhusela kuya kuhlala kuxhomekeke kuyilo lwenkqubo. Ukukhetha izixhobo ze-SMT ezisemgangathweni ophezulu nezihambelanayo kubalulekile ekuphuculeni ukuthembeka kwemveliso, ukunciphisa amazinga okusilela, kunye nokuphucula ukhuphiswano ngokubanzi.
