SMD simba inductors ndeimwe yesimbi girazi uranium resistors. Yakajairika modhi inductance, inozivikanwawo seyakajairwa modhi choke, inowanzo shandiswa kusefa yakajairwa magineti emagetsi masaini masaini mumakomputa ekuchinja magetsi. Mukugadzirwa kwebhodhi redunhu, iyo yakajairwa modhi inductor inoshandawo seEMI sefa yekudzvanya iyo electromagnetic wave inogadzirwa neakakwira-kumhanya chiratidzo mutsara kubva mukupenya kuenda kunze. Icho chinopikisa chakagadzirwa nemusanganiswa wesimbi poda uye uranium girazi poda, iyo inodhindwa-yakadhindwa pane yakakwirira-simba SMD simba inductor pane substrate. Kunyorova kwakanaka, kukwirisa tembiricha kuramba, yakaderera tembiricha coefficient. Kushandiswa kwemazita ekugadzira tekinoroji kwave kwakajairika, uye chikamu chezvigadzirwa zvemagetsi zvakaunganidzwa neSMT zvakapfuura 90%. nyika yangu inofanira kunge yakapinda hunyanzvi hweSMT kubvira kuma1980s. Nekuvandudzwa kwemidziyo midiki yekugadzira SMT, chiyero chekushandiswa kwezvikamu zveSMT chakawedzerwa. Aviation, aerospace, instrumentation, maturusi emuchina uye mamwe mapoka anoshandisawo SMT kugadzira mabheti madiki akasiyana ezvigadzirwa zvemagetsi kana zvikamu.
Resistors mumwe nemumwe anonzi resistors muhupenyu hwezuva nezuva. Chinhu chazvino-chinogadzirisa chakabatana kune chinopikisa mudunhu. Iyo resistor ine yakagadziriswa kukosha kwepini mbiri uye inoshandiswa kudzikamisa ikozvino inoyerera kuburikidza nebazi iyo yakabatanidzwa. Kupokana uko ukoshi hwayo husingagone kushandurwa kunonzi fixed resistance. Avo vane musiyano wekupikisa vanonzi potentiometers kana variable resistors. The virtual resistance is linear, kureva kuti, yenguva pfupi kuburikidza nekupikisa inoenderana nekushandiswa kwemhepo inopera. Variable resistor yevoltage divider. One kana maviri anofambiswa esimbi anodzvanya zvakasimba pane yakafumurwa resistor. Iyo yekubata chinzvimbo inosarudza kuramba pakati pechero mugumo weanopikisa uye wekubata.
Zvimiro zveSMD simba inductor vagadziri 'zvigadzirwa
Ukuru hudiki uye uremu huremu; Inokodzera reflow soldering uye wave soldering; · Iyo mota inogona kuve yakasimba uye yakasimba; · Mutengo wakaderera wegungano, unoenderana neanoshanda yekuisa michina; · Yakakwira mechanic simba uye yakakwirira frequency maitiro. Kuti udzivirire waya, zvishwe uye coils kubva kunze remagineti uye kuderedza kupindira kweiyo electromagnetic munda inogadzirwa nedunhu pane zvimwe zvikamu, magineti kudzivirira kana electromagnetic shielding nzira dzinowanzo gamuchirwa.
Ndezvipi zvinhu zvinogadzirwa neSMD simba inductors?
SMT resistors inogadzirwa zvakasiyana kubva kune inotevera data:
Iyo yekutanga zvinhu ndeye alumina, uye iyo yekupokana data ndeye ruthenium oxide
1. Substrate
2. Resistance paste
3. Dzokorora ruzivo
4. Positive nhungamiro data uye divi nhungamiro data
5. Kuchengetedza kwekutanga kwegirazi G16. Kuchengetedza kwechipiri kwegirazi G27.
