TXM24M0004252FBCEO00T 无源贴片晶振产品概述

一、产品基本信息

TXM24M0004252FBCEO00T是雅晶鑫(YJX)推出的一款无源贴片晶振,型号中“24M”明确核心频率为24MHz,“SMD2520-4P”代表采用2.5mm×2.0mm的4引脚贴片封装,属于小型化时钟源器件。无源晶振区别于有源晶振(内置振荡电路),需外接匹配电容和振荡电路起振,具有成本低、体积小、抗干扰性强的特点,是电子设备中最常用的基础时钟元件之一。

二、核心性能参数详解

1. 频率与精度控制

  • 标称频率:24MHz(行业常用时钟频率,可分频得到12MHz、6MHz等子频率);
  • 常温频差:±10ppm(25℃环境下,频率偏差≤240Hz),满足多数中低精度场景需求;
  • 温度频率稳定度:±30ppm(全工作温度范围内,最大频偏≤720Hz),覆盖-40℃~+85℃的温度变化影响。

2. 负载电容与匹配要求

推荐负载电容12pF,无源晶振的振荡频率由晶体特性与外接负载电容总和决定(需包含PCB杂散电容,约1-3pF)。设计时需确保外接陶瓷电容(如10pF+2pF)与杂散电容之和接近12pF,否则会导致频率偏移超出规格。

3. 等效串联电阻(ESR)

ESR为55Ω,是晶振振荡时的能量损耗指标:ESR越小,振荡电路(如反相器、时钟芯片)越容易起振。55Ω处于常规无源晶振的合理范围,可避免因ESR过大导致起振困难或振荡不稳定。

三、封装与机械特性

采用SMD2520-4P贴片封装,尺寸为2.5mm(长)×2.0mm(宽)×0.8mm(典型厚度),4引脚布局符合行业标准,适配自动化SMT贴装工艺(回流焊温度≤260℃)。封装材料为耐高温陶瓷,引脚采用抗氧化镀层,可降低焊接不良率,同时满足小型化设备的PCB空间需求。

四、工作环境与可靠性

  • 工作温度范围:-40℃+85℃(工业级温度规格,优于商业级0℃70℃),可适应户外、工业现场等温差较大的环境;
  • 可靠性:无源晶振无内置有源器件,抗振动、抗冲击性能较好,典型寿命可达10年以上,适合长期运行的设备。

五、典型应用场景

  1. 工业控制领域:PLC(可编程逻辑控制器)、传感器模块、工业机器人控制器等,需稳定时钟驱动逻辑电路,工业级温度范围满足现场需求;
  2. 消费电子与物联网:智能穿戴(手表、手环)、蓝牙耳机、智能家居网关、低功耗物联网模块(LoRa、蓝牙5.0),小型化封装适配设备轻薄化设计;
  3. 通信辅助时钟:24MHz可分频为12MHz/6MHz,用于WiFi 2.4G模块、4G/5G终端的基带辅助时钟;
  4. 车载电子:部分车载辅助系统(仪表盘背光控制、车载音响时钟),-40℃~+85℃覆盖车载极端温度。

总结

TXM24M0004252FBCEO00T以24MHz核心频率、工业级温度范围、小型化贴片封装为核心优势,兼顾成本与性能,是工业控制、消费电子、物联网等领域的高性价比时钟源选择。

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
