Ngokuthuthuka kwemboni ye-elekthronikhi, imikhiqizo ye-elekthronikhi isiqalile ukukhombisa inkambiso yentuthuko "yesimanjemanje", okuyi-miniaturization, ukuhlanganiswa, imisebenzi eminingi, namandla aphezulu. Ukuze uhambisane nokuthandwa kwemikhiqizo ye-elekthronikhi, imboni ye-elekthronikhi idinga ngokuphuthumayo umkhiqizo we-inductance omncane ngosayizi, amandla aphezulu, izindleko eziphansi futhi ofanele ukufakwa okuhlanganisiwe. Kuvela ama-inductors ayingxenye eyodwa.
Izinzuzo kanye nokubi kwama-inductors ahlanganisiwe
Ama-inductors ocezu olulodwa, abizwa nangokuthi "ama-alloy inductors" noma "ama-inductors abunjiwe", afaka umzimba oyisisekelo kanye nomzimba osongwayo. Isistimu yesisekelo yakhiwa ngokufaka i-die-casting umzimba osongayo ngokushumeka umzimba osongayo kwimpushana kazibuthe yensimbi. Kunezinhlobo ezimbili zama-inductors adidiyelwe, i-DIP kanye ne-SMD, futhi zonke ziyi-die-casting, ezidinga ukwelashwa kokufakwa kwempushana okuphezulu. Njengamanje, izinto ezisetshenziswa kakhulu emakethe i-alloy iron powder. Izakhiwo ezinhle zezinto ezibonakalayo kanye nokwakheka okukhethekile kwesakhiwo kwenza ukwakheka kwe-inductor kuzinze kakhudlwana, i-impedance ephansi, nokusebenza okungcono kokuzamazama komhlaba, ngakho-ke kunokuguqulwa okuphakeme okusebenzayo.
Uma kuqhathaniswa nama-inductors endabuko, ama-inductors ocezu olulodwa nawo anezinzuzo ezilandelayo:
1. Isakhiwo sokuvikela kazibuthe, isekethe kazibuthe evaliwe, ukuphazamiseka okunamandla okulwa nozibuthe, ukubhuza okuphansi kakhulu, nokufakwa kokuminyana okuphezulu.
2. I-low-loss alloy powder die-casting, impedance ephansi, akukho ukuphela komthofu, amandla amancane e-parasitic.
3. Isakhiwo sesiqephu esisodwa, esiqinile futhi esiqinile, ukujiya okunembile komkhiqizo, nokulwa nokugqwala.
4. Usayizi omncane kanye nomthamo omkhulu wamanje, usengakwazi ukugcina izinga lokushisa elihle kakhulu lamanje kanye nezici zamanje zokugcwala ngaphansi kwefrikhwensi ephezulu kanye nendawo yokushisa ephezulu.
5. Ukukhethwa okuhle kwezinto zokwakha, ubuciko obuhle, kanye nokufakwa kwemvamisa yokusebenza ebanzi (kufika ku-5MHz noma ngaphezulu).
ukushiyeka:
Ukusebenza kuyinkimbinkimbi kakhulu kunama-inductor endabuko futhi kudinga imishini yokukhiqiza i-inductor eyinkimbinkimbi kakhulu, ngakho-ke izindleko zokukhiqiza ziphakeme kakhulu.
Kodwa-ke, eminyakeni yamuva nje, ngokuthuthuka kobuchwepheshe bokukhiqiza kanye nokutshalwa kwezimali okukhulu kwemishini yokukhiqiza, intengo yama-inductors ahlanganisiwe kancane kancane iphenduka izakhamuzi.
