Ibiranga ibicuruzwa
Pack Ipaki idasanzwe:
- 7.0 × 1.5 × 1,4 mm hamwe na 4 J - biganisha ku mwanya - igishushanyo mbonera cya PCB
Ubuso - Guhuza umusozi:
- Ibisigarira byizewe - byakozwe na SMD yamashanyarazi yatunganijwe neza
Porogaramu
- Yateguwe kuri RTC / kureba porogaramu, MC - 146 kHz ya kristu ya kristu ya FR07S4 itanga igihe cyizewe kumasaha nyayo, microcontrollers, sisitemu yo gupima mumodoka, nibikoresho bigendanwa.
Ibyiza byibicuruzwa
Pin - gusimbuza guhuza:
Urutonde rwa FR07S4 rwa HCI ni pin itaziguye - kugeza - gusimbuza pin ya MC-146 ya EPSON hamwe nigiciro cyo gupiganwa.
Kurwanya Ibidukikije bikabije:
Igumana imikorere ihamye mubushuhe bwagutse (-40 dogere +85 dogere) kandi irwanya ihungabana / kunyeganyega, bigatuma ikoreshwa mumodoka, inganda, kandi zikoreshwa hanze.
icyemezo
MC - 146 kHz Crystal 7.0 x 1.5 FR07S4 ibicuruzwa byuruhererekane byujuje RoHS kubusone na Halogen-Ubuntu.
Ibibazo
Q1: Nigute ubushyuhe bugira ingaruka kumatiku ya oscillator?
Igisubizo: Guhindura ubushyuhe bitera umuvuduko ukabije; TCXOs / OCXOs yishyura ibi binyuze mumuzunguruko cyangwa amashyiga.
Q2: Nshobora kubona icyitegererezo hamwe nimpinduka zihariye (urugero, ikimenyetso cyihariye)?
Igisubizo: Yego, ikimenyetso cyihariye (ikirangantego, umubare wigice, nibindi) birahari kubitegeko byicyitegererezo (Birenze cyangwa bingana na 10pcs). Amafaranga yinyongera arashobora gusaba ibimenyetso bigoye; wemeze ibisobanuro hamwe nitsinda ryacu ryambere.
Ibirangantego: mc-146 khz kristal 7.0 x 1.5, Ubushinwa mc-146 khz kristal 7.0 x 1.5 abakora, abatanga isoko
