SMD ikon inductors daya ne daga cikin karfen gilashin uranium resistors. Inductance na yau da kullun, wanda kuma aka sani da shaƙawar yanayin gama gari, galibi ana amfani dashi don tace sigina na tsangwama na yanayin gama gari a cikin sauya wutar lantarki. A cikin ƙirar allon kewayawa, inductor ɗin gama gari shima yana aiki azaman tacewa na EMI don murkushe igiyar wutan lantarki da layin sigina mai sauri ya haifar daga haskakawa zuwa waje. Resistor ne da aka yi da cakuda foda na karfe da foda na gilashin uranium, wanda aka buga a allo akan inductor mai ƙarfi na SMD akan ma'auni. Kyakkyawan wettability, high zafin jiki juriya, low zazzabi coefficient. Yin amfani da fasahar taro na yau da kullun ya zama ruwan dare gama gari, kuma adadin samfuran lantarki da SMT ya haɗa ya wuce 90%. yakamata kasata ta shiga dabarun SMT tun daga shekarun 1980. Tare da haɓaka ƙananan kayan samar da kayan aikin SMT, an ƙara fadada iyakokin amfani da nau'ikan SMT. Jiragen sama, sararin samaniya, kayan aiki, kayan aikin injin da sauran nau'ikan kuma suna amfani da SMT don samar da ƙananan nau'ikan samfuran lantarki ko sassa daban-daban.

Resistors ana kiransu daban-daban a cikin rayuwar yau da kullun. Abun iyakance na yanzu da aka haɗa zuwa resistor a cikin da'ira. Resistor yana da ƙayyadaddun ƙimar fil biyu kuma ana amfani dashi don iyakance halin yanzu da ke gudana ta reshen da aka haɗa shi. Juriya wadda ba za a iya canza ƙimar juriya ba ana kiranta tsayayyen juriya. Wadanda ke da juriya mai canzawa ana kiran su potentiometers ko m resistors. Juriyar kama-da-wane ta layi ce, wato, madaidaicin halin yanzu ta hanyar juriya yayi daidai da wutar lantarkin da ake amfani da shi. Mai canzawa resistor don mai raba wutar lantarki.

Fasalolin samfuran masana'antun wutar lantarki na SMD
Ƙananan girma da nauyi mai sauƙi; · Dace da reflow soldering da igiyar ruwa soldering; · Motar na iya zama mai ƙarfi da ƙarfi; · Ƙananan farashin taro, daidaitawa tare da kayan aiki mai aiki; · Babban ƙarfin injina da halayen mitar mita. Domin kare wayoyi, madaukai da coils daga filin maganadisu na waje da kuma rage tasirin kutsawa na filin lantarki da ke haifar da da'ira akan wasu abubuwan, garkuwar maganadisu ko hanyoyin kariya na lantarki galibi ana ɗaukar su.
Wadanne abubuwa ne aka yi da inductors na wutar lantarki na SMD?
SMT resistors ana yin su daban daga bayanan masu zuwa:
