Ayini ama-SMD inductors? Zisetshenziselwa ini? Iningi lazo aliqondakali kahle. Umhleli olandelayo we-BIG uzokunikeza isingeniso esiningiliziwe:
Ama-inductors e-SMD afaka ama-inductors anamandla aphezulu. Inezici ze-miniaturization, ikhwalithi ephezulu, isitoreji samandla aphezulu kanye nokumelana okuphansi. Isetshenziswa kakhulu kumabhodi okubonisa ikhompuyutha, amakhompyutha e-notebook, ukuhlela inkumbulo ye-pulse, kanye neziguquli ze-DC-DC.
Kunezinhlobo ezi-4 zama-chip inductors: i-chip yefilimu elincanyana, ilukiweyo, inxeba lentambo kanye nama-inductors amaningi. Izinhlobo ezimbili zohlobo lwamanxeba ocingo kanye nohlobo lwe-laminated zivame ukusetshenziswa. Owokuqala uwumkhiqizo we-miniaturization yama-inductors amanxeba endabuko; lokhu kwakamuva kwenziwa kusetshenziswa ubuchwepheshe bokuphrinta obunezingqimba eziningi kanye nobuchwepheshe bokukhiqiza obunama-laminated. Ivolumu incane kunaleyo yama-chip inductors anenxeba. Kungumkhiqizo oyinhloko othuthukiswe emkhakheni wezingxenye ze-inductive.
I-Thin-film chip chip inductors inezici zokugcina i-Q ephezulu, ukunemba okuphezulu, ukuzinza okuphezulu nosayizi omncane kubhendi yefrikhwensi ye-microwave. Ama-electrode angaphakathi agxilwe kungqimba olufanayo, futhi ukusatshalaliswa kwenkundla kazibuthe kugxilile, okungaqinisekisa ukuthi amapharamitha wedivayisi ngemva kokukhwezwa awashintshi kakhulu, futhi abonise izici ezinhle zokuvama ngaphezu kuka-100MHz.
Isici sama-chip inductors alukiweyo ukuthi inductance yevolumu yeyunithi ku-1MHz inkulu kunamanye ama-chip inductors, amancane ngosayizi, futhi kulula ukuyifaka ku-substrate. Isetshenziswa njengengxenye kazibuthe encane yokucubungula amandla.
Izici zama-chip inductors anenxeba anhlobonhlobo e-inductance (mH～H), ukunemba okuphezulu kwe-inductance, ukulahlekelwa okuphansi (i-Q enkulu), yamanje enkulu evumelekile, ifa lenqubo yokukhiqiza eqinile, ubulula, kanye nezindleko eziphansi, kodwa Ububi buwukuthi ukuthi inqunyelwe ekuthuthukisweni okuncane. I-ceramic core winding type chip inductor ingagcina i-inductance ezinzile kanye nevelu ye-Q ephezulu ngokufanele imvamisa ephezulu kangako, ngakho ithatha indawo kusekethe yamafrikhwensi aphezulu.
Ama-inductors astakiwe anezindawo ezinhle zokuvikela kazibuthe, ukuminyana okuphezulu kwe-sintering, namandla amahle omshini. Okubi izinga lokuphasa eliphansi, izindleko eziphakeme, i-inductance encane, kanye nenani eliphansi le-Q. Uma kuqhathaniswa nocingo lwe-chip inductors, ukupakisha kunezinzuzo eziningi: usayizi omncane, ohambisana ne-miniaturization ye-circuit, i-circuit magnetic evaliwe, ngeke iphazamise izingxenye ezizungezile, futhi ngeke iphazamiseke izingxenye ezingomakhelwane, ezizuzisa izingxenye eziphezulu. -Density ukufakwa amadivaysi; isakhiwo esihlanganisiwe, ukwethembeka okuphezulu; ukumelana nokushisa okuhle kanye ne-solderability; umumo ojwayelekile, olungele ukukhiqizwa okufakwe phezulu okuzenzakalelayo.
