TXM40M0004252HBCEO00T 无源贴片晶振产品概述

一、产品基本属性

TXM40M0004252HBCEO00T是雅晶鑫(YJX)推出的无源石英贴片晶振,属于高频时钟源器件。该型号采用SMD2520-4P封装(2.5mm×2.0mm×0.8mm典型尺寸),4引脚表面贴装设计,适配自动化SMT生产流程;因无源特性无需额外驱动电路,仅需匹配负载电容即可稳定起振。产品针对工业级及消费电子的高可靠性需求优化,覆盖宽温工作范围,是中高频时钟同步场景的常用选型。

二、核心性能参数解析

关键参数直接决定适用场景,具体解析如下:

  1. 频率与频差:标称频率40MHz,常温(25℃±2℃)频差±10ppm,换算为绝对偏差仅400Hz(40MHz×10⁻⁶),属于中高精度范畴,可满足射频模块、时钟同步等对频率稳定性要求较高的场景;
  2. 负载电容:15pF(典型值),为晶振起振提供匹配阻抗,电路设计需并联15pF左右陶瓷电容,确保起振稳定性;
  3. 频率稳定度:±30ppm(-40℃~+85℃范围内),即温度变化时最大频率偏差1200Hz(40MHz×30⁻⁶),宽温覆盖能力满足工业环境及车载低温场景;
  4. 等效串联电阻(ESR):25Ω(最大值),低ESR设计降低起振功耗,减少外围电路依赖,提升电路可靠性;
  5. 工作温度:-40℃~+85℃,符合工业级器件温区要求,可在极端环境下稳定工作。

三、封装与可靠性设计

SMD2520-4P封装是该产品的核心设计亮点:

  • 小型化:2.5mm×2.0mm紧凑尺寸,适配智能手机、智能穿戴、物联网节点等小型化设备的PCB布局,有效节省板级空间;
  • 可靠性:采用陶瓷封装+真空密封工艺,内部石英晶体片经高精度光刻加工,抗振动(最大振动加速度10g)、抗冲击性能优异,可应对运输及使用中的机械应力;
  • 兼容性:4引脚贴片设计兼容主流SMT贴片机,焊接温度(260℃/10s)符合RoHS标准,无铅环保。

四、典型应用场景

基于性能与封装特点,该晶振广泛应用于以下领域:

  1. 消费电子:智能手机蓝牙/WiFi射频模块、智能手表时钟源、机顶盒/路由器时钟同步电路;
  2. 工业物联网:传感器节点、PLC控制器、工业网关高频时钟模块(宽温覆盖适合户外/车间环境);
  3. 车载电子:车载信息娱乐系统、胎压监测模块辅助时钟(满足-40℃低温启动需求);
  4. 通信设备:小型基站、无线AP频率参考源(中高精度频差满足数据传输同步要求)。

五、选型优势总结

对比同类无源晶振,该型号具备以下优势:

  1. 性能均衡:常温频差±10ppm、宽温稳定度±30ppm、低ESR25Ω,在精度与可靠性间实现平衡;
  2. 环境适应性强:-40℃~+85℃温区覆盖工业级需求,陶瓷封装抗恶劣环境;
  3. 小型化适配:SMD2520-4P封装适合高密度PCB设计,满足便携设备空间限制;
  4. 供应稳定:雅晶鑫作为国内晶振主流厂家,产能充足、交期可控,性价比优于进口同类产品。

该产品通过了RoHS、REACH等环保认证,可满足不同行业的合规性要求,是中高频时钟同步场景的高性价比选型。

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
