Codsiyada
- Thermistor-ka SMD 2520 XT22M4 wuxuu leeyahay codsiyo ballaadhan, oo loo habeeyay taleefannada 5G, GPS, dareemayaasha IoT, iyo aaladaha cidhifka AI.
Faa'iidooyinka alaabta
Deganaanshaha Heerkulka Sare:
Wuxuu isku daraa magdhowga thermistor + TCXO ee saxda ah ± 5ppm, oo ka sarreeya kiristaalo caadiga ah ee xaaladaha kuleylka kuleylka.
Qiimaha -Xalka wakhtiga saxda ah ee la hagaajiyay:
Waxay hoos u dhigtaa qiimaha BOM iyo TCXO-dhaqameedyada iyadoo la ilaalinayo xasilloonida la midka ah.
shahaado
Taxanaha SMD Thermistor Crystal 2520 XT22M4 waxa uu si buuxda u waafaqsan yahay RoHS/REACH{3}}shalay, hogaanka-free, iyo halogen- bilaash ah.
FAQ
Q1: Sida loo tijaabiyo Thermistor Crystal?
A: 1) Hubi isbeddellada iska caabbinta heerkulka (NTC/PTC).
2) La soco xasiloonida inta jeer ee (± ppm) ee cadaadiska kulaylka.
3) Xaqiiji oscillation; hadday midna jirin, hubi koofiyadaha xamuulka/ heerka darawalnimada.
Q2: Arrimaha Guud & Xalka Thermistor Crystal?
A: Arrinta 1: Soo noqnoqoshada xad dhaafka ah
Sababta: Thermistor gabow/guuldarrida wareegga wareegga
Fix: Beddel crystal ama hubi shabakada magdhowga
Arrinta 2aad: Ma jiro Oscillation
Sababta: Isku dheelitir la'aanta awoodda culeyska/qaabaynta PCB-ga oo liita
Hagaajin: Hagaajin awoodda ama habee dajinta (ka fogow calaamadaha xawaaraha{0} sare)
Arrinta 3: Burburka Iibka
Cause: Reflow temperature too high (>260 darajo)
Hagaajin: Raac astaanta alxanka (kuleylka ka hor → dib u qulqul → qaboojin)
