TAXM22.1184M2QLFCDT1T 产品概述

一、产品简介

TAXM22.1184M2QLFCDT1T 是由雅晶鑫(YJX)全国产线生产的一款贴片晶振,标准频率为 22.1184 MHz,采用 SMD5032-2P(5.0×3.2 mm,2 脚)封装。该器件针对工业级及通信、计时、微控制器时钟等对精确频率有要求的应用,提供稳定且可靠的振荡基准。

二、主要参数

  • 频率:22.1184 MHz
  • 常温频差:±30 ppm
  • 频率稳定度(含温度影响等):±20 ppm
  • 负载电容(CL):20 pF
  • 等效串联电阻(ESR):30 Ω(典型)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:SMD5032-2P(贴片,2 脚)
  • 品牌/产地:YJX(雅晶鑫),国产

三、性能特点

  • 高频点稳定,22.1184 MHz 为常用通信与串口波特率衍生频率,方便系统直接整定时钟。
  • ESR 适中(≈30 Ω),兼容多数微控制器和专用振荡器输入电路,能保证较快启动与稳定运行。
  • 宽工作温度范围满足工业级环境需求,适用于-40~+85℃ 的恶劣环境。
  • SMD5032 小尺寸封装,适合高密度贴片组装,便于自动化回流焊工艺。

四、典型应用

  • MCU/MPU 主时钟与外部时钟源
  • 串口与通信设备(UART、Modem、无线模块基频)
  • 测试测量仪器与计时电路
  • 工业控制、嵌入式系统与消费电子的时钟参考

五、封装与焊接建议

  • 封装为 SMD5032,请按 PCB 贴片规范设计相应焊盘并留足锡膏量,避免偏位。
  • 推荐采用厂家提供的回流焊曲线进行焊接验证;对回流工艺敏感时,请先做小批量实验。
  • 晶体工作时应远离强电磁干扰源与大电流导线,减小相位噪声与干扰耦合。

六、选型与电路注意事项

  • 负载电容 CL = 20 pF,若使用外接两端电容,需根据 PCB 的寄生电容(典型 2–5 pF)按公式 C ≈ 2×(CL − Cstray) 计算,常见取值约 33 pF/片(示例,建议结合实际测量确认)。
  • ESR 较高时可能影响启动时间,需在所用振荡器电路中验证启动可靠性。
  • 在高精度应用中请同时考虑温度漂移与长期老化,对频差要求较高的场合建议做实际频率标定。

七、可靠性与存储

  • 符合工业温度等级的可靠性设计,适合长期工作;出厂时建议按厂家建议存储条件保存,避免潮湿、高温与强振动环境。
  • 建议在 SMT 贴装前对包装进行干燥处理(若包装标识需回烘),并按厂方提供的储运与回流指南操作,以保证出货良率与长期稳定性。

如需完整数据手册(频率-温度曲线、等效电路图、焊接曲线及机械尺寸图),建议向雅晶鑫(YJX)或授权经销商索取,以便在设计和量产阶段进行更精确的验证。

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
