TAXM4M2GLFBET2T 无源贴片晶振产品概述

一、产品定位与基本属性

TAXM4M2GLFBET2T是雅晶鑫(YJX)推出的工业级无源石英晶振,属于频率基准元件,核心作用是为电子电路提供稳定的4MHz时钟信号。作为无源器件,它需依赖外部振荡电路(如单片机内部振荡器)实现起振,具备成本低、结构简单、可靠性高的特点,适用于对频率稳定性和宽温适应性有要求的各类电子设备。

二、核心电气参数详解

该晶振的关键参数直接决定其适用场景,具体解析如下:

  • 标称频率:4MHz
    为电路提供基准时钟频率,4MHz属于中低频段,广泛适配微控制器、通信模块等的时钟源需求,是工业控制、消费电子的常用频率。
  • 常温频差:±30ppm
    常温(25℃±2℃)下,实际振荡频率与标称值的最大偏差为百万分之三十。换算为实际值:4MHz×30ppm=120Hz,偏差极小,满足工业级设备的频率精度要求。
  • 负载电容:20pF
    无源晶振需外接两个对称的负载电容(通常接在振荡电路输入/输出端),20pF是推荐匹配值,直接影响振荡频率准确性,使用时需按此参数选择外接电容。
  • 频率稳定度:±30ppm
    工作温度范围内(-40℃~+85℃),频率相对于常温的最大偏差。该参数体现温度适应性,±30ppm可确保宽温环境下时钟信号的一致性。
  • 等效串联电阻(ESR):90Ω
    晶振的串联等效电阻,ESR越小越易起振。90Ω处于工业级无源晶振常规区间,适配STM32、51系列等主流单片机的内部振荡电路,起振成功率高。
  • 工作温度范围:-40℃~+85℃
    覆盖工业级温度区间,可适应户外设备、车载电子、低温仓库等极端环境,无需额外温度补偿电路即可稳定工作。

三、封装与品牌背景

3.1 封装特点

采用HC-49S-SMD贴片封装,具备以下优势:

  • 体积紧凑:符合标准HC-49S尺寸(约11.5×4.7×3.8mm),适配PCB空间有限的紧凑设计;
  • 贴装便捷:支持SMT自动化生产,直接通过贴片机焊接,提高生产效率,降低人工成本;
  • 抗干扰强:贴片引脚与PCB贴合紧密,抗振动、抗冲击性能优于直插式封装,适合恶劣工况。

3.2 品牌优势

雅晶鑫(YJX)是国内专注频率元件研发的厂商,产品覆盖石英晶振、振荡器等,具备:

  • 工艺成熟:高精度石英晶体加工工艺,确保频率参数一致性;
  • 测试严格:每批次全参数测试,符合工业级可靠性标准;
  • 性价比高:针对中低端应用优化成本,适合批量采购。

四、典型应用场景

结合参数特性,该晶振适用于以下场景:

  1. 工业控制设备:PLC、变频器、传感器模块,稳定时钟保证数据采集精度和控制逻辑准确性;
  2. 车载电子:车载导航、行车记录仪、蓝牙模块,宽温范围满足-40℃低温启动和+85℃高温工作;
  3. 智能家居:智能门锁、温湿度传感器、智能音箱,贴片封装适配小型化设计,稳定频率保证通信可靠性;
  4. 通信模块:蓝牙4.0、WiFi 2.4G模块的辅助时钟源,4MHz可作为基准分频/倍频基础;
  5. 医疗监测设备:小型血糖监测仪、心率手环,避免频率偏差导致的数据误差。

五、性能优势与可靠性总结

  1. 宽温稳定:-40℃~+85℃工业级温度范围,极端环境下频率偏差可控;
  2. 高可靠性:ESR=90Ω易起振,贴片封装抗振动,适合恶劣工况;
  3. 成本可控:无源设计无需内置振荡电路,相比有源晶振成本降低30%以上,适合批量应用;
  4. 适配性强:4MHz兼容主流单片机,20pF负载电容匹配常规电路设计。

TAXM4M2GLFBET2T作为雅晶鑫主力工业级无源晶振,凭借稳定的频率特性、宽温适应性和贴片封装便捷性,成为多领域电子设备时钟电路的可靠选择,可满足大部分中低端应用场景的需求。

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.
