TXM26M0004322CBCDO00T 贴片石英晶体谐振器产品概述

一、产品身份与基础定位

TXM26M0004322CBCDO00T是雅晶鑫(YJX) 推出的SMD3225封装4引脚贴片石英晶体谐振器,核心频率为26MHz,属于工业级通用型时钟基准器件。型号中“TXM”为雅晶鑫晶振系列标识,“26M”明确主频率,“3225”对应封装尺寸(3.2×2.5mm),后续字符则匹配负载电容、频差等参数组合,是针对中高精度时钟需求设计的成熟量产产品。

二、关键性能参数深度解析

该晶振的核心参数围绕“稳定性、精度、环境适应性”三个维度优化,具体如下:

  1. 频率精度与稳定度:常温(25℃)频差±10ppm,即频率偏差不超过26MHz×10×10⁻⁶=±260Hz;全工作温度范围内频率稳定度±20ppm,能有效抵消温度变化带来的漂移,满足工业场景下的时钟一致性要求。
  2. 负载电容与ESR:匹配负载电容为9pF(电路设计需以该值为基准),等效串联电阻(ESR)≤30Ω——低ESR可降低振荡电路功耗,同时提升振荡幅度稳定性,减少噪声干扰概率。
  3. 工作环境范围:温度适应区间为-40℃+85℃,湿度范围5%95%(非凝结),覆盖工业级设备典型场景(如户外物联网节点、车间控制模块)。

三、封装与物理特性

采用SMD3225-4P贴片封装,尺寸仅3.2mm×2.5mm×0.8mm(典型厚度),4引脚设计支持表面贴装工艺(SMT),适合高密度PCB布局(如智能穿戴、小型通信模块的窄空间设计)。封装材料为耐高温陶瓷,可承受回流焊等常规焊接工艺,焊接后无引脚变形、开裂风险。

四、典型应用场景

26MHz是通信、消费电子领域的主流基准频率,该晶振的应用场景覆盖:

  1. 通信与物联网:WiFi 6/蓝牙5.0模块、LoRa网关、NB-IoT节点(多数无线芯片的时钟基准为26MHz);
  2. 消费电子:智能手表、平板电脑、机顶盒、便携式音频设备(需精准时钟同步多媒体信号);
  3. 工业控制:PLC(可编程逻辑控制器)、传感器模块、工业机器人控制器(宽温设计适配车间温差);
  4. 车载电子:部分车型的信息娱乐系统时钟模块(需注意:该型号为工业级,若需车规需确认雅晶鑫车规系列)。

五、产品核心优势

相比同频率、同封装竞品,该晶振具备以下实用价值:

  1. 宽温稳定性突出:-40℃+85℃的温度范围,比普通商业级(0℃70℃)覆盖更广,适合户外或温差变化大的场景;
  2. 精度与成本平衡:常温±10ppm的频差满足大多数中高精度需求(如WiFi芯片时钟同步精度通常≤20ppm),低ESR设计提升可靠性;
  3. 小体积高密度适配:3225封装是小型化设备主流选择,可直接替换同尺寸竞品,无需调整PCB布局;
  4. 供货与品质保障:雅晶鑫具备稳定产能与质量管控,常规订单供货周期1-2周,常备库存支持小批量(1000片起订)需求。

六、选型与使用注意事项

为确保性能发挥,需注意以下细节:

  1. 负载电容匹配:电路设计中需保证晶振两端等效负载电容为9pF(若不符,可通过外接电容调整),否则导致频率偏移;
  2. 焊接工艺控制:回流焊温度≤260℃,焊接时间≤10秒(过温会导致晶振老化、频率漂移);
  3. 抗干扰布局:晶振应靠近时钟芯片输入端,远离高频噪声源(如电源模块、射频天线);
  4. 存储条件:未焊接晶振需存储在25℃±5℃、湿度40%~60%环境中,避免潮湿/高温暴露。

该产品是26MHz频率段中兼顾精度、稳定性与成本的高性价比选择,适用于多数需要工业级时钟基准的电子设备。

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
