TXM12.288M0004322FBCDO00T 无源贴片晶振产品概述

一、产品基础属性

该型号为雅晶鑫(YJX) 旗下无源贴片晶振,核心标识如下:

  • 封装规格:SMD3225-4P(3.2×2.5mm超小贴片封装,4引脚设计)
  • 产品类型:无源石英晶振(依赖外部振荡电路起振)
  • 型号编码:TXM为品牌系列前缀,12.288M为标称频率,后续字符为参数编码与批次标识

二、核心电气参数详解

1. 频率特性

  • 标称频率:12.288MHz(工业与消费电子领域常用标准频率,适配UART、SPI等串口通信时钟)
  • 常温频差:±10ppm(25℃环境下频率偏差≤0.00012%,满足多数设备对时钟精度的基础要求)
  • 频率稳定度:±20ppm(覆盖工作温度范围时,总频率偏差控制在±20ppm内,温漂性能优异)

2. 阻抗与负载特性

  • 等效串联电阻(ESR):60Ω(中等阻抗水平,适配主流MCU、FPGA的内置振荡电路,无需额外匹配电阻)
  • 负载电容:12pF(需电路端焊接12pF匹配电容,建议选用NP0/C0G材质以降低温度系数影响)

3. 环境适应性

  • 工作温度范围:-40℃~+85℃(工业级宽温设计,可适应户外、车载、车间等恶劣环境)
  • 存储温度范围:-55℃~+125℃(满足长期仓储的温度稳定性要求)

三、典型应用场景

该型号因小封装、宽温稳定、通用频率的特点,广泛应用于以下领域:

1. 工业控制与物联网

  • PLC可编程逻辑控制器、工业传感器、电机驱动模块的时钟基准
  • 低功耗蓝牙(BLE)、ZigBee节点的时钟源(12.288MHz适配115200bps等常用波特率)

2. 车载与消费电子

  • 车载中控、行车记录仪的辅助时钟(满足-40~85℃车载环境)
  • 智能穿戴设备(手表、手环)的低功耗时钟基准

3. 嵌入式系统

  • STM32、ATmega等MCU的外部振荡源(SMD3225封装适配高密度PCB设计)
  • FPGA的辅助时钟(补充主时钟精度,提升系统稳定性)

四、产品核心优势

  1. 小封装高密度:3.2×2.5mm封装比传统DIP封装节省约70%空间,适配小型化设备(如无线模块、智能传感器)
  2. 宽温可靠稳定:工业级温度范围+±20ppm频率稳定度,避免极端温度下时钟偏移导致设备故障
  3. 通用兼容性强:12.288MHz为行业标准频率,12pF负载电容适配多数主流芯片,无需特殊电路设计
  4. 成本效益优异:雅晶鑫成熟量产型号,性价比高,适合中低端到中端设备的批量应用

五、应用注意事项

  1. 负载电容匹配:必须焊接12pF匹配电容(NP0/C0G材质),若负载电容偏差超过±2pF,可能导致频率偏移≥5ppm
  2. PCB布局要求:晶振引脚需靠近MCU振荡引脚(走线≤10mm),避免靠近高频信号线(如WiFi天线),防止电磁干扰
  3. 焊接工艺控制:回流焊峰值温度≤245℃(时间≤10秒),手工焊接温度≤350℃(时间≤3秒),避免高温损坏晶振
  4. 静电防护:无源晶振对静电敏感(阈值≤2kV),生产过程需佩戴静电手环,使用防静电包装与工具

六、选型参考对比

与同频率SMD3225封装竞品相比:

  • 常温频差:本型号±10ppm(竞品多为±20ppm),精度更高
  • 温度范围:本型号-4085℃(竞品多为070℃商业级),适用场景更广
  • ESR:60Ω处于同类型产品中等水平,平衡了振荡稳定性与功耗

该型号是一款高性价比工业级无源晶振,可满足多数中精度时钟需求,尤其适合对空间、温度适应性要求较高的设备设计。

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
