TXM27.12M0004322DBBDO00T 无源贴片晶振产品概述

一、产品基本信息

TXM27.12M0004322DBBDO00T是雅晶鑫(YJX)推出的无源贴片晶振,型号编码中通过前缀“TXM”明确品牌属性,“27.12M”标注核心标称频率,“3225”对应封装尺寸,后缀则包含生产批次及性能标识。该产品采用表面贴装工艺,无需额外电源驱动,依赖外接振荡电路实现时钟信号输出,是电子设备中高精度时钟基准的常用元件。

二、核心电气参数解析

该晶振的电气性能经严格测试,关键指标适配多场景需求:

  1. 标称频率:27.12MHz,属于射频通信领域的常用时钟频率,可覆盖蓝牙、2.4G无线等模块的时钟需求;
  2. 常温频差:±10ppm,即常温(25℃)下频率偏差不超过271.2Hz,精度满足中高端电子设备的时钟同步要求;
  3. 负载电容:10pF,无源晶振需外接匹配的负载电容(通常为两个10pF电容并联),该参数直接影响振荡频率准确性,设计时需严格遵循;
  4. 频率稳定度:±20ppm,指工作温度范围内(-40℃~+85℃)的频率变化量,最大偏差为542.4Hz,符合工业级环境的稳定性要求;
  5. 等效串联电阻(ESR):30Ω,较低的ESR可提升振荡电路起振速度,减少信号衰减,保证输出信号稳定性;
  6. 工作温度范围:-40℃~+85℃,覆盖工业场景的高低温变化,可适应户外、车载等复杂环境。

三、封装与机械特性

该晶振采用SMD3225-4P封装,具体特性如下:

  • 尺寸规格:3.2mm(长)×2.5mm(宽)×0.8mm(厚),属于小型化贴片封装,适配高密度PCB设计;
  • 引脚配置:4引脚设计,部分引脚可用于接地屏蔽,降低电磁干扰(EMI),提升信号抗干扰能力;
  • 焊接兼容性:支持回流焊、波峰焊等常规贴片焊接工艺,回流焊温度需控制在260℃±5℃以内,焊接时间不超过10秒;
  • 可靠性:封装采用陶瓷材料,抗冲击、抗振动性能良好,可满足电子设备的长期稳定运行需求。

四、典型应用场景

结合频率、温度范围及封装特性,该晶振广泛应用于以下领域:

  1. 无线通信设备:蓝牙模块、Wi-Fi模块、2.4G无线耳机、智能家居网关等,为射频电路提供稳定时钟基准;
  2. 消费电子:智能手环、智能手表、蓝牙耳机等可穿戴设备,小型化封装适配设备紧凑设计;
  3. 工业控制:PLC可编程控制器、传感器模块、工业物联网节点等,工业级温度范围满足现场环境要求;
  4. 汽车电子:车载蓝牙、胎压监测传感器等,-40℃~+85℃的温度范围可适应车载环境变化;
  5. 物联网设备:低功耗无线节点、智能电表、智能门锁等,无源设计降低设备功耗与成本。

五、选型对比优势

相较于同类无源晶振,该产品具有以下优势:

  • 精度与稳定性平衡:常温±10ppm频差结合±20ppm温度稳定度,兼顾精度与宽温适应性;
  • 小型化设计:3225封装体积小,适配当前电子设备轻薄化趋势;
  • 低ESR提升性能:30Ω ESR确保振荡电路起振快、信号稳定,减少误码率;
  • 无源设计成本低:无需额外电源驱动,电路设计简单,降低整体方案成本;
  • 工业级可靠性:陶瓷封装及宽温度范围,适合 harsh 环境下长期使用。

该产品凭借稳定的电气性能、小型化封装及工业级可靠性,成为通信、消费电子、工业控制等领域的理想时钟基准元件。

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
