TXM25M0004503LDCDO00T 无源贴片晶振产品概述

一、产品基本概况

TXM25M0004503LDCDO00T是雅晶鑫(YJX)推出的一款无源贴片晶振,专为工业级及消费电子领域的基础时钟需求设计。该型号采用SMD5032-4P封装,核心频率为25MHz,具备小型化、高可靠性的特点,可适配多数单片机、MCU及低功耗电子设备的振荡电路,是平衡成本与性能的通用型时钟源。

二、核心性能参数详解

1. 频率精度与稳定度

  • 常温频差:±20ppm(对应频率偏差为500Hz),满足一般电子设备对基础时钟精度的要求,可覆盖消费电子、工业控制等场景的常规应用;
  • 工作温度范围:-40℃~+85℃(工业级温度范围),在此区间内频率稳定度为±20ppm,即温度变化导致的最大频率偏差仍控制在500Hz以内,可稳定适配户外设备、车载周边等温度波动场景。

2. 电气特性

  • 负载电容:20pF(无源晶振的关键匹配参数),电路设计需配置总负载电容为20pF的电容(通常采用两个10pF陶瓷电容并联于晶振两端),以保证振荡频率的准确性;
  • 等效串联电阻(ESR):30Ω,ESR是衡量晶振起振难度的核心指标,30Ω属于中等偏优水平,可适配多数MCU的晶振输入引脚驱动能力,降低振荡电路设计复杂度。

三、封装与工艺特点

TXM25M0004503LDCDO00T采用SMD5032-4P封装:

  • 尺寸:5.0mm×3.2mm×1.2mm(常规5032封装),小型化设计节省PCB空间,适合高密度布局的电子设备;
  • 4引脚结构:除2个功能振荡引脚外,额外2个引脚可用于接地或增强机械稳定性,提升抗干扰能力;
  • 贴片式设计:适配自动化回流焊工艺,降低生产人工成本,提高批量生产一致性。

四、典型应用领域

该晶振因性能均衡、成本可控,广泛应用于以下场景:

  1. 消费电子:智能穿戴(手表、手环)、智能家居传感器(温湿度、人体感应)、小型家电控制板;
  2. 工业控制:PLC模块、传感器采集单元、小型工业控制器;
  3. 通信周边:低速率无线模块(蓝牙5.0、ZigBee)、WiFi模块的辅助时钟;
  4. 车载电子:车载音响、仪表盘辅助电路、非高温核心区域的传感器(如胎压监测辅助);
  5. 物联网设备:低功耗物联网节点、智能网关的基础时钟源。

五、选型与使用注意事项

  1. 负载电容匹配:必须使用总负载电容为20pF的电容,建议选用NP0材质陶瓷电容(温度系数稳定),避免电容漂移影响频率;
  2. 焊接工艺:采用回流焊(峰值温度≤260℃,时间≤10秒),禁止手工焊接时温度过高损坏晶振;
  3. 抗干扰设计:晶振附近避免布高频信号线,可在周围加接地屏蔽,减少电磁干扰;
  4. 温度适配:若应用场景温度超出-40℃+85℃,需更换宽温/超宽温晶振(如-55℃+125℃)。

六、产品优势总结

  • 工业级温度范围,满足多数户外/工业场景需求;
  • 30Ω低ESR,易起振、稳定性好;
  • 小型化SMD5032封装,适配高密度PCB;
  • 成本可控,适合批量应用。

该型号可作为多数电子设备的通用时钟源,为系统提供稳定可靠的25MHz基础振荡信号。

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
