  • 环境耐受:工作温度-40℃~+85℃,覆盖工业级户外/车间环境;
  • 封装规格:SMD3225-4P(3.2mm×2.5mm表面贴装,4引脚),体积小巧,节省PCB空间。

二、关键性能优势

相较于无源晶振或窄参数有源晶振,TFOM12M4RHKCNT2T具备以下突出优势:

  1. 宽电压兼容性:1.8V至5V的电压覆盖,解决不同芯片平台的电源适配问题——既支持低功耗物联网节点的1.8V供电,也兼容传统工业设备的5V电源,简化系统设计;
  2. 低功耗设计:5mA工作电流满足智能穿戴、电池传感器等对功耗敏感的场景,延长设备续航;
  3. 宽温稳定可靠:-40℃至+85℃的温度范围,可应对户外监测站、车间PLC等极端环境,频率稳定度无明显衰减,避免时钟偏差导致的系统同步故障;
  4. CMOS输出适配性:直接对接数字芯片时钟输入,信号完整性好,减少EMI干扰风险,无需额外电平转换电路;
  5. 小封装省空间:3.2×2.5mm封装厚度约1mm,适合蓝牙耳机、智能手环等便携设备的紧凑布局,提升产品小型化程度。

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
