TX322524M4FBCE2T 贴片石英晶体谐振器产品概述

一、产品基本定位

TX322524M4FBCE2T是雅晶鑫(YJX)品牌推出的24MHz贴片石英晶体谐振器,采用SMD3225-4P小型化封装,主打中精度、宽温适应性,专为消费电子、通信、工业控制等领域的时钟参考源设计。该型号属于YJX经典3225系列,以高可靠性、低损耗、易集成的特点,适配各类小型化电子设备的高密度PCB布局需求。

二、核心性能参数详解

作为石英晶体谐振器,其关键参数直接影响时钟稳定性,需重点关注:

  1. 频率与频差:标称频率24MHz,常温(25℃)频差±10ppm(即频率偏差范围为24MHz±240Hz),满足多数中精度系统的基础时钟要求;
  2. 负载电容:标准负载电容12pF,客户PCB设计需匹配该值,避免谐振频率偏移;
  3. 频率稳定度:全工作温度范围(-40℃~+85℃)内稳定度±30ppm(即温度变化导致的频率偏差≤24MHz±720Hz),可适应不同环境温度下的稳定运行;
  4. 等效串联电阻(ESR):典型值30Ω,ESR越低则谐振效率越高、信号损耗越小,有助于提升时钟输出的信噪比;
  5. 工作温度范围:-40℃至+85℃,覆盖工业级与消费级的常见环境区间,无需额外降额使用。

三、封装与引脚说明

该产品采用SMD3225-4P封装,具体参数如下:

  • 尺寸规格:3.2mm(长)×2.5mm(宽)×0.8mm(高),属于小型化贴片封装,适合高密度PCB布局;
  • 引脚配置:4引脚贴片设计,其中2个为晶体电极引脚(输出谐振信号),另外2个为机械支撑/接地引脚(可接GND增强抗干扰性);
  • 焊接兼容性:支持回流焊、波峰焊等标准SMT工艺,焊接温度需遵循雅晶鑫规范(峰值温度≤260℃/10秒),避免热应力损坏。

四、典型应用场景

24MHz是电子设备中通用的时钟频率,该型号的应用场景覆盖:

  1. 消费电子:智能手机、平板电脑、智能手表的CPU时钟、外设接口(如USB、I2C)时钟;
  2. 通信设备:无线路由器、交换机、蓝牙模块的射频参考时钟、基带处理时钟;
  3. 工业控制:PLC可编程控制器、传感器模块、工业电源的定时单元;
  4. 物联网设备:智能家居网关、智能电表、安防摄像头的核心控制时钟。

五、可靠性与设计注意事项

  1. 可靠性优势:宽温范围设计+低ESR特性,配合SMD封装的抗振动能力,可满足7000小时以上的长期稳定运行;
  2. 设计关键要点:
    • 负载电容匹配:PCB上需在晶体电极引脚处并联12pF负载电容(建议用两个6pF电容并联,减少寄生电容影响);
    • 抗干扰设计:晶振周围1cm范围内避免高频电路(如射频模块),引脚附近添加接地过孔;
    • 焊接工艺:回流焊时控制升温速率≤3℃/秒,避免晶振因热冲击损坏。

六、选型延伸建议

若需更高精度(如±5ppm)或汽车级宽温(-55℃~+125℃),可选择YJX同系列:

  • 高精度需求:TX322524M5FBCE2T(常温频差±5ppm);
  • 汽车级需求:TX322524M6FBCE2T(AEC-Q200认证,宽温范围);
  • 振荡器需求:切换至YJX XO系列(带输出缓冲,无需外部负载电容)。

该型号凭借平衡的性能与成本优势,成为中小批量电子设备时钟设计的主流选择之一。

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
