  • 输出负载:典型负载电容15pF(适配多数数字芯片输入阻抗,匹配性好)

3. 封装与引脚定义

SMD3225-4P为4引脚表面贴装封装,引脚功能明确:

  • 引脚1:VDD(1.2V电源输入,需稳定供电)
  • 引脚2:GND(接地端,需可靠连接以减少噪声)
  • 引脚3:OUT(25MHz CMOS时钟输出,直接对接数字电路时钟输入)
  • 引脚4:NC(空脚,无电气连接,焊接时无需处理)

三、应用场景

SX3M25.000E20F30THN的低功耗、宽温稳定特性,使其适配以下场景:

  1. 低功耗物联网设备:传感器节点、无线模组(LoRa、BLE)、智能穿戴(手表、手环)的时钟源
  2. 工业控制模块:PLC、工业传感器、远程监控终端的基准时序
  3. 便携式电子:智能手机、平板电脑、电子书阅读器的辅助时钟(如实时时钟模块)
  4. 消费类电子:机顶盒、路由器、智能音箱的主时钟或子时钟
  5. 医疗电子:小型医疗设备(血糖仪、血压计)的稳定时序控制

四、产品优势特点

  1. 宽温稳定可靠:-40℃~+85℃工业级温度范围,频率稳定度±30ppm,满足极端环境(如户外传感器、车间设备)需求
  2. 低功耗设计:1.2V供电+2mA工作电流,显著降低系统功耗,尤其适合电池供电的便携式/物联网产品
  3. 小体积易集成:SMD3225-4P封装(3.2×2.5mm),节省PCB空间,适配小型化产品设计(如可穿戴设备、微型模组)
  4. 高兼容性:CMOS输出兼容主流数字芯片(MCU、FPGA、DSP、ASIC等),无需额外电路即可直接对接
  5. 高可靠性:采用SCTF成熟石英晶体工艺,老化率低,平均无故障时间(MTBF)≥10^6小时,适合长期连续工作场景

五、工作环境与可靠性

  • 工作温度:-40℃~+85℃(工业级标准,覆盖绝大多数应用场景)
  • 存储温度:-55℃~+125℃(存储环境宽松,便于库存管理与运输)
  • 抗振动冲击:符合行业标准,振动(10~2000Hz)≤1g,冲击(1ms)≤10g,适合运输及现场安装
  • 湿度适应性:工作湿度5%~95%RH(无凝露),满足潮湿环境(如户外、沿海地区)需求

总结:SX3M25.000E20F30THN是一款高性价比工业级有源晶振,兼顾低功耗、宽温稳定与小体积,是物联网、工业控制、便携式电子等领域时钟方案的理想选择。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
