TAXM1431818MRLBCCT2T 贴片石英晶振产品概述

一、产品基本定位

TAXM1431818MRLBCCT2T是雅晶鑫(YJX)推出的高频贴片石英谐振器,以14.31818MHz为核心工作频率,适配中精度时钟同步、信号基准等场景,广泛应用于消费电子、工业控制及通信设备领域。其采用SMD3225小型化封装,兼顾体积与可靠性,是传统直插晶振的替代优选方案,尤其适合对空间敏感的小型化设备。

二、核心电气参数解析

该产品的关键参数直接决定了其适用场景,具体解析如下:

  1. 频率精度:标称频率14.31818MHz,常温(25℃)频差±10ppm,即频率波动范围为±143.18Hz,满足视频信号同步、基础通信时钟的精度需求(无需温补即可覆盖大部分民用场景);
  2. 负载电容:20pF,需与电路匹配电容(通常为20pF左右)配合,若负载电容偏差超过10%可能导致谐振频率偏移,设计时需注意PCB布局的寄生电容影响;
  3. 频率稳定度:±15ppm(-40℃~+85℃工作温度范围),即温度变化时频率最大波动±214.77Hz,宽温特性适配户外监控、工业PLC等环境;
  4. 等效串联电阻(ESR):50Ω,属于同类产品中的较低水平,ESR越低则起振速度越快(实测起振时间<10ms)、抗干扰能力越强,可减少电路中额外滤波元件的使用;
  5. 工作温度:-40℃~+85℃,覆盖大部分民用及工业级场景,无需额外温控措施即可稳定工作。

三、封装与机械特性

采用SMD3225-4P封装(3.2mm×2.5mm×0.8mm典型厚度),属于小型化表面贴装封装,具备以下优势:

  • 体积仅为传统HC-49U直插晶振的1/5,大幅节省PCB布局空间,适合智能手机、微型传感器等小型设备;
  • 4脚贴片设计,焊接兼容性强,支持回流焊(峰值温度260℃/10s)、波峰焊等自动化生产工艺,符合RoHS无铅环保要求;
  • 陶瓷封装外壳,抗机械振动(10g~2000Hz)及冲击(1000g/0.1ms),可靠性达到工业级标准,可承受多次焊接循环。

四、性能优势与典型应用

4.1 核心性能优势

  • 宽温稳定:-40℃~+85℃范围内频率波动控制在±15ppm,避免低温下频率漂移导致设备开机故障或信号失步;
  • 起振快速:50Ω低ESR设计,起振时间<10ms,满足设备开机快速同步的需求(如机顶盒、智能电视的视频解码启动);
  • 精度适配:±10ppm常温频差覆盖90%以上中精度场景,无需额外温补组件降低成本;
  • 小型化集成:SMD3225封装适配高密度PCB设计,适合5G基站模块、智能穿戴等设备的小型化需求。

4.2 典型应用场景

  1. 视频设备:NTSC制式电视、监控摄像头的色副载波基准(14.31818MHz是NTSC色同步信号的标准频率,确保画面色彩同步);
  2. 通信模块:蓝牙5.0、WiFi 6模块的时钟源(可分频得到1.8432MHz、3.6864MHz等常用通信频率);
  3. 工业控制:PLC、传感器节点的时钟基准(宽温特性适配户外工业环境,如农业物联网传感器);
  4. 消费电子:机顶盒、DVD播放器的视频解码时钟(确保画面无卡顿、音频同步)。

五、品牌与品质保障

雅晶鑫(YJX)作为国内专业晶振厂商,该产品具备以下品质保障:

  • 符合RoHS 2.0、REACH等环保标准,无铅焊接兼容,可通过SGS等第三方检测;
  • 批量生产一致性好,参数离散性控制在±5%以内,适合大规模自动化生产;
  • 提供1年以上质保,售后技术支持覆盖参数匹配、电路设计建议(如负载电容匹配方案)。

该产品以高性价比、宽温稳定及小型化优势,成为中精度时钟场景的主流选择,可满足多数民用及工业设备的时钟基准需求。

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
