F322512MUBCE2O是雅晶鑫(YJX)推出的工业级表面贴装石英晶体振荡器,核心参数覆盖频率基准、电气特性、环境适配三大维度,具体如下:
参数类别 具体参数 说明 基本频率 12MHz 主流数字电路常用基准频率 常温频差 ±10ppm 25℃环境下频率偏差控制在工业级精度范围 频率稳定度 ±10ppm(-40℃~+85℃) 全工作温度范围内频率波动极小 输出模式 CMOS 兼容TTL/CMOS逻辑电平,无需电平转换 工作电压范围 1.8V~3.3V DC 覆盖多数MCU、传感器的供电需求 典型工作电流 5mA(3.3V下) 低功耗设计,适配电池供电设备 封装类型 SMD3225-4P 3.2×2.5mm小型化封装,节省PCB空间 工作温度范围 -40℃~+85℃ 工业级宽温,适配户外/车载等严苛场景1.8V~3.3V的电压范围可直接匹配STM32低功耗系列、51单片机、蓝牙模块等主流芯片,无需额外DC-DC转换电路;5mA的典型工作电流在同频率、同封装晶振中处于前列,能有效延长电池供电设备(如智能手环、IoT节点)的续航时间。
±10ppm的常温频差和全温稳定度,可满足工业控制、通信接口的精度要求:例如12MHz作为UART波特率(如115200bps)的倍频源时,频率偏差小于0.1%,可避免数据传输丢包;在PLC模块中,稳定的时钟能保证电机控制、传感器采样的时序一致性。
SMD3225-4P封装尺寸仅3.2mm×2.5mm,比传统DIP封装缩小60%以上,适合智能家居控制器、智能手表等小型化产品;4引脚布局符合行业通用标准(通常1脚输出、2脚地、3脚电源、4脚悬空),焊接兼容性强。
-40℃~+85℃的工作温度范围,可覆盖车间、户外基站、车载电子等场景的温度变化;雅晶鑫的石英晶体工艺确保产品抗振动、抗冲击性能,符合IEC 60068-2-6等可靠性标准。
PLC模块、电机控制器、传感器节点等设备需稳定时钟保证控制时序,F322512MUBCE2O的宽温特性可适配-20℃~+70℃的车间环境,避免温度波动导致的频率漂移。
智能手表、蓝牙耳机、智能家居遥控器等产品对尺寸和功耗敏感,小封装+低功耗设计可满足PCB空间紧凑、续航要求高的需求。
温湿度传感器、智能门锁、无线网关等IoT节点需稳定时钟支持WiFi/蓝牙通信,12MHz基准可保证协议栈的正常运行,宽电压适配不同电池供电方案。
UART、SPI、I2C等接口的基准时钟,12MHz是常见波特率(9600bps、115200bps)的倍频源,CMOS输出可直接驱动数字电路,无需缓冲器。
F322512MUBCE2O凭借“宽温、宽压、小封装、高稳定”的综合优势,成为工业控制、消费电子、IoT等领域的高性价比时钟源选择,可有效简化系统设计并提升设备可靠性。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
