TXM12M0004252FBCEO00T 贴片石英晶振产品概述

TXM12M0004252FBCEO00T是雅晶鑫(YJX)推出的一款高性价比无源贴片石英晶体谐振器,采用SMD2520-4P超小型封装,以12MHz为核心标称频率,兼顾精度、稳定性与成本优势,广泛适配工业控制、消费电子、通信终端等多领域应用场景。

一、产品基本定位

该晶振属于石英晶体谐振器范畴,核心作用是为电子系统提供稳定的时钟基准信号。不同于有源晶振(需外部供电),其为无源设计,需配合外部振荡电路(如MCU内置振荡器+匹配电容)实现振荡,具备成本低、体积小、功耗低等特点,是中小批量电子设备的常用时钟方案。

二、核心电气性能参数

(一)频率与温度特性

  • 标称频率:12MHz(工业与消费电子领域的通用时钟频率,适配多数MCU、通信芯片的时钟输入需求);
  • 常温频差:±10ppm(25℃环境下频率偏差≤±120Hz,满足一般精度要求,可覆盖多数非高频应用场景);
  • 工作温度范围:-40℃~+85℃(宽温设计,可适应工业现场、车载辅助设备等复杂环境的温度波动);
  • 频率稳定度:±30ppm(涵盖-40℃~+85℃全温区的频率变化,确保宽温下时钟信号的稳定性,避免因温度波动导致系统功能异常)。

(二)负载与阻抗特性

  • 负载电容:12pF(晶振工作时需匹配的外部等效电容值,实际应用中需结合PCB寄生电容调整并联电容,通常建议使用10~15pF的陶瓷电容,确保总负载电容接近12pF);
  • 等效串联电阻(ESR):120Ω(无源晶振的关键阻抗参数,ESR越低则振荡电路越易启动、功耗越低,120Ω属于SMD2520封装晶振的常规合理范围,适配多数MCU内置振荡器)。

三、封装与物理特性

该晶振采用SMD2520-4P封装,具体物理参数如下:

  • 尺寸:2.5mm(长)×2.0mm(宽)×0.7mm(高)(超小型封装,可显著节省PCB布局空间,适配便携式、小型化电子设备);
  • 引脚数:4引脚(贴片式,兼容SMT自动化生产工艺,支持回流焊、波峰焊,焊接效率高);
  • 封装材质:陶瓷封装(耐高温、抗机械冲击,确保焊接与使用过程中的可靠性)。

四、典型应用场景

结合其性能参数与封装特点,TXM12M0004252FBCEO00T适用于以下场景:

  1. 工业控制设备:如PLC模块、传感器节点、小型工控机,宽温设计可适应车间-20℃~+60℃的温度波动;
  2. 消费电子:智能穿戴(智能手环、手表)、小型家电(加湿器、智能插座)、便携式音频设备,超小封装适配设备小型化需求;
  3. 低速率通信终端:蓝牙BLE模块、WiFi低功耗模块、LoRa节点,12MHz频率与低ESR特性可保障无线通信的时钟稳定性;
  4. 医疗小型设备:便携式血糖监测仪、体温传感器,需稳定时钟信号确保数据采集精度;
  5. 车载辅助设备:车载充电器、行车记录仪(非核心安全系统),宽温范围可适应车载环境的温度变化。

五、品牌与可靠性优势

雅晶鑫(YJX)作为国内专注石英晶振研发与生产的品牌,该产品具备以下优势:

  • 可靠性测试:经过回流焊温度测试(260℃±5℃)、温度循环测试(-40℃~+85℃,100循环)、湿度测试(85℃/85%RH,1000小时),符合GB/T 14862-2013等行业标准;
  • 环保合规:符合RoHS 2.0、REACH等环保指令,无铅焊接兼容;
  • 批量一致性:生产过程采用自动化分选设备,确保批量产品的频率、ESR等参数一致性,降低量产时的调试成本。

六、使用注意事项

  1. 负载电容匹配:实际应用中需测量PCB寄生电容(通常1~3pF),并联电容值=12pF - 寄生电容,避免因负载电容偏差导致频率偏移或振荡异常;
  2. 焊接工艺:回流焊温度曲线需符合雅晶鑫提供的参数(峰值温度≤260℃,时间≤10秒),避免过热导致晶振性能下降;
  3. 布局要求:晶振应尽量靠近MCU的OSC引脚,走线长度≤10mm,避免与高频信号线并行,减少电磁干扰;
  4. 存储条件:未焊接的晶振应存储在25℃±5℃、湿度≤60%的环境中,避免长期暴露在空气中导致引脚氧化。

总结:TXM12M0004252FBCEO00T以高性价比、宽温稳定、小型化封装为核心优势,是工业与消费电子领域通用时钟方案的理想选择,可满足多数中小批量电子设备的时钟基准需求。

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.
