TXM24M0004252LBCEO00T 无源贴片晶振产品概述

TXM24M0004252LBCEO00T是雅晶鑫(YJX)推出的一款无源贴片石英晶振,专为需要稳定24MHz时钟信号的电子设备设计,兼顾成本控制与环境适应性,广泛适配消费电子、工业控制等多领域应用。

一、产品基本定位与品牌背景

雅晶鑫(YJX)作为国内专业晶振制造商,专注于石英晶振、温补晶振等产品的研发与生产,其无源晶振系列以高性价比、稳定可靠著称。TXM24M0004252LBCEO00T属于该品牌SMD2520-4P封装的标准频率系列,采用无源设计(无需外部驱动电路),依赖外接负载电容实现谐振,适合对时钟精度要求中等、需批量应用的场景。

二、核心电气参数详解

该型号的核心参数围绕频率稳定性、谐振特性展开,关键指标如下:

  1. 频率规格:标准输出频率24MHz,属于电子设备中常用的基础时钟频率,可通过分频/倍频适配不同模块需求;
  2. 常温频差:±10ppm(百万分之一),即常温(25℃左右)下频率偏差不超过240Hz(24MHz×10ppm),满足大部分设备的时钟精度要求;
  3. 负载电容:20pF,无源晶振需匹配外接20pF电容以维持谐振稳定,若电容偏差过大,会导致频率偏移或振荡失效;
  4. 频率稳定度:±30ppm(工作温度范围内),即-40℃~+85℃区间内,频率总变化量不超过720Hz,确保宽温环境下时钟信号稳定;
  5. 等效串联电阻(ESR):55Ω,该参数影响振荡幅度与稳定性,55Ω属于无源晶振的合理范围,电路易起振且抗干扰能力较好。

三、封装与物理特性

TXM24M0004252LBCEO00T采用SMD2520-4P贴片封装,具体特性:

  • 尺寸:约2.5mm×2.0mm×0.8mm(长×宽×高),体积小巧,节省PCB空间;
  • 引脚:4引脚贴片式,符合SMT自动化贴装工艺,适配高速贴片生产线;
  • 封装材料:采用耐高温陶瓷封装,抗机械振动、冲击能力优于插件式晶振,适合移动设备或工业现场环境。

四、典型应用场景

结合参数特性,该型号适用于以下场景:

  1. 消费电子:智能手表、蓝牙耳机、智能家居设备的时钟源(需稳定24MHz信号,成本敏感);
  2. 工业控制:PLC模块、传感器节点、小型工业控制器的定时电路(宽温-40~85℃适配工业环境);
  3. 通信设备:小型路由器、物联网网关、低功耗通信模块的同步时钟(无源设计降低功耗与成本);
  4. 车载电子:部分宽温要求的车载辅助模块(如胎压监测、车载蓝牙),需注意其未标注汽车级认证,需确认应用场景是否符合。

五、可靠性与环境适应性

该型号的环境适应性满足工业级要求:

  • 工作温度:-40℃~+85℃,覆盖大部分户外、工业现场的温度变化;
  • 存储温度:通常为-55℃~+125℃(雅晶鑫常规无源晶振参数),便于运输与存储;
  • 抗干扰性:无源晶振无内置驱动,受外部干扰影响较小,且陶瓷封装可屏蔽部分电磁干扰;
  • 寿命:石英晶振的固有寿命较长,正常使用下可稳定工作10年以上。

六、选型与使用注意事项

  1. 负载电容匹配:必须使用20pF的陶瓷电容(推荐NPO材质,温度系数稳定),若电路中实际负载电容偏离,需通过公式计算调整外接电容;
  2. 精度需求:若应用需更高精度(如±5ppm),需选择同品牌同封装的高精度系列;
  3. PCB设计:焊盘需与SMD2520-4P引脚尺寸匹配,避免虚焊;晶振周围应减少高频走线干扰;
  4. 起振条件:无源晶振需搭配合适的振荡电路(如反相器+反馈电阻),确保ESR≤振荡电路的起振阈值(通常<100Ω即可满足)。

总结:TXM24M0004252LBCEO00T作为一款高性价比无源贴片晶振,以24MHz标准频率、宽温稳定性、小体积封装为核心优势,适合对时钟精度要求中等、需批量应用的电子设备,是消费电子、工业控制等领域的实用选型。

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.
