- Mini 49 SMD 32.768kHz Crystal FL37S2 ikurikirana ya RTC nisaha, microprocessor, ingengabihe hamwe nubugenzuzi, metero nibikoresho byabigenewe.
Ibyiza byibicuruzwa
Ibikoresho bya Customer Iboneza:
Birashoboka rwose guhuza umukiriya - ibisabwa bya tekiniki byihariye
Birebire - Kwiyemeza gutanga amasoko:
Inkunga yumushinga umurage wizewe kandi Nta EOL (Impera - ya - Ubuzima) iteganijwe koherezwa mumahanga
icyemezo
Mini 49 SMD 32.768kHz Crystal FL37S2 ikurikirana ni RoHS na REACH yujuje, kandi yujuje icyerekezo - kubuntu na halogen - kubuntu.
Ibibazo
Q1: Nigute ushobora kumenya byihuse niba wakoresha ubushyuhe buke cyangwa bugari mugihe uhitamo ubushyuhe bukora?
Igisubizo: Reba aho igikoresho gikora. Kubicuruzwa bisanzwe bya elegitoroniki yo mu nzu (urugero, disikuru ya Bluetooth), hitamo urugero rugufi rwubushyuhe (-20 ~ +70 dogere). Kubinyabiziga, ibikoresho byo hanze, cyangwa ibindi bintu bifite ubushyuhe butandukanye, shyira imbere ubushyuhe bwagutse (-40 ~ +85 dogere).
Q2: Igipimo cyo gusaza kwa kristu oscillator isobanura iki, kandi dukwiye kubyitaho?
Igisubizo: Bivuga intera yumwaka itandukana. Igipimo cyo gusaza cya 3ppm / mwaka ntigisanzwe {{2} devices ibikoresho bisanzwe birashobora gukora imyaka myinshi nta makosa agaragara. Kuri ultra - hejuru - ibikoresho byuzuye, kalibrasi isanzwe irahagije.
Q3: Nigute ushobora guhitamo ubushobozi bwimitwaro mumahitamo aboneka ya 7pF / 9pF / 12.5pF?
Igisubizo: Hitamo ukurikije ibisabwa byumuzunguruko. Reba mu gitabo gikubiyemo ibikoresho cyangwa utugishe inama mbere kugirango umenye ubushobozi bwimitwaro ihuye, byemeza ko umusaruro uva muri kristu oscillator.
Ibirangantego: Icyuma gishobora 49 SMD 32.768kHz Crystal, Ubushinwa Icyuma gishobora 49 SMD 32.768kHz Abakora Crystal, abatanga ibicuruzwa
