1. Umkhiqizo Uphelileview
Ama-chip ferrite beads ochungechunge lwe-Murata BLM18PG aklanyelwe ukucindezela umsindo kumasekethe kagesi. Lezi zingxenye zisebenza njengezithiyo kumaza omsindo, zivimbela ukuphambuka kwesimo samagagasi esignali ngenkathi zinciphisa amathuba okuzwakala kwe-resonance. Zifaneleka kakhulu kumasekethe lapho imigqa yomhlaba ezinzile ingatholakali khona, njengoba zingadingi uxhumano lomhlaba.
Isakhiwo sesivikelo se-nickel sama-electrode angaphandle sinikeza ukumelana okuhle kakhulu nokushisa kwe-solder, okuqinisekisa ukusebenza okuthembekile ezinhlelweni ezahlukahlukene. Uhlobo lwe-BLM_P lunokumelana okuphansi kwe-DC, okwenza lube luhle kakhulu kumasekethe anomoya ophezulu. Lolu chungechunge lwenzelwe izinhlelo zokusebenza ezijwayelekile.
Isithombe 1: I-Murata BLM18PG471SN1D I-Chip Ferrite Bead. Lesi sithombe sibonisa ukusondelana kwe-ferrite bead encane, engunxande eneziphetho zensimbi.

3. Iziqondiso Zokusebenzisa
Lawa ma-ferrite beads angamadivayisi okufaka phezulu (SMD) futhi avame ukufakwa emabhodini wesekethe ngesikhathi senqubo yokukhiqiza. Amasu afanele okunamathisela i-solder abalulekile ekusebenzeni okuthembekile. Qinisekisa ukuthi ingxenye ibekwe kahle kuma-solder pads ngokuya ngomklamo wesekethe.
Ukuze uthole ukucindezela komsindo okuhle kakhulu, cabanga ngebanga lokuvama komsindo ohlose ukuwuvimba. I-BLM18PG471SN1D inikeza i-impedance engu-470 Ω ku-100MHz, okwenza isebenze kahle emsindweni wemvamisa ephezulu. Ukumelana kwayo okuphansi kwe-DC (uhlobo lwe-BLM_P) kuyivumela ukuthi isetshenziswe emigqeni yamandla noma emigqeni yesignali ethwala ugesi omkhulu ngaphandle kokubangela ivolumu ephezulu.tage kwehle.
Njengoba lobu buhlalu be-ferrite bungadingi uxhumano lomhlaba, bufanelekela izifunda lapho umugqa womhlaba ungazinzile noma ungatholakali khona. Lokhu kwenza kube lula ukwakheka kwesifunda kanye nokuhlelwa kwaso.
4. Izimiso Zokusebenza
Ama-Ferrite beads asebenza njengama-resistor ancike kuma-frequency. Kuma-frequency aphansi (isb., ama-DC noma ama-signal frequency aphansi), abonisa i-impedance ephansi kakhulu, okuvumela i-signal oyifunayo ukuthi idlule ngokunciphisa okuncane. Njengoba i-frequency ikhula, ikakhulukazi ebangeni lama-frequency omsindo, izinto ze-ferrite ziyalahleka, futhi i-impedance ye-bead iyanda kakhulu, inciphisa ngempumelelo umsindo wama-frequency aphezulu.
Lesi sici sivumela i-ferrite bead ukuthi icindezele umsindo ngaphandle kokuhlanekezela i-signal waveform, ngokungafani ne-resistor elula enganciphisa wonke amaza. Uchungechunge lwe-BLM18PG lwenzelwe ukuvimbela ukuhlanekezela kwe-signal waveform ngenkathi ngesikhathi esifanayo kunciphisa amathuba okuzwakala kwe-resonance, okungenzeka ngama-capacitor noma ama-inductor.
5. Isitoreji Nokuphatha
Ukuze ugcine ukusebenza kahle kanye nokuthembeka, gcina ama-ferrite bead endaweni eyomile, kude nokukhanya kwelanga okuqondile kanye namazinga okushisa aphezulu. Gwema ukucindezeleka komshini noma amandla amakhulu ngesikhathi sokuphatha nokuhlanganisa, njengoba lokhu kungalimaza ingxenye noma ama-terminal ayo.
Njalo phatha izingxenye ngezinyathelo zokuphepha ezilwa nokungaguquguquki ukuze uvimbele umonakalo ovela ekukhishweni kwe-electrostatic (ESD), ikakhulukazi uma uzihlanganisa kumasekethe kagesi abucayi.
6. Ulwazi Lokuphepha
Lezi zingxenye zenzelwe ukusetshenziswa kobungcweti ekwakhiweni nasekukhiqizweni kwesekethe kagesi. Zincane futhi zingaba yingozi yokuminyana uma zigwinywa. Zigcine kude nezingane.
Uma ufaka i-solder, qiniseka ukuthi ungenisa umoya ngokwanele ukuze ugweme ukuphefumula umusi. Landela zonke izinqubo zokuphepha ezijwayelekile zokuphatha izingxenye zikagesi kanye nokusebenza ngemishini yokunamathisela.
7. Iwaranti kanye Nokusekela
Ukuze uthole ulwazi oluthile lwewaranti kanye nokusekelwa kobuchwepheshe mayelana nemikhiqizo yeMurata, sicela ubheke i-Murata Manufacturing Co., Ltd. esemthethweni. webnoma xhumana nabasabalalisi babo abagunyaziwe. Njengoba lezi ziyizingxenye ze-elekthronikhi ezingasebenzi, iwaranti yabo ivame ukumboza amaphutha okukhiqiza ngaphansi kwezimo zokusebenza ezijwayelekile.
Ukuze uthole amanothi esicelo anemininingwane, idatha yokuthembeka, kanye nemibuzo eyengeziwe yobuchwepheshe, kunconywa ukuthi ubheke imibhalo esemthethweni kaMurata kanye neziteshi zokusekela.
