TAXM26M4RCBCCT2T无源贴片晶振产品概述

一、产品基本属性

TAXM26M4RCBCCT2T是雅晶鑫(YJX)推出的无源贴片晶振,采用SMD3225-4P封装,标称频率26MHz,属于工业级宽温应用的时钟基准器件。作为无源晶振,其无需内置振荡电路,依赖外部MCU、ASIC等芯片的振荡模块驱动,具备成本可控、适配性强的特点,广泛用于中低端电子设备的时钟同步与频率基准场景。

二、核心电气性能参数

该型号的关键电气参数决定了其应用范围与性能表现,具体如下:

  1. 标称频率:26MHz(主流通用频率,适配多数通信、消费电子模块的时钟需求);
  2. 常温频差:±10ppm(25℃环境下,实际频率与标称值的偏差≤260Hz,满足常规设备的精度要求);
  3. 负载电容:9pF(无源晶振需外接总负载电容匹配,通常在晶振两端各并联4.5pF电容,确保振荡频率稳定);
  4. 频率稳定度:±50ppm(-40℃~+85℃工作温度范围内,频率变化量≤1.3kHz,覆盖工业级环境的温度波动);
  5. 等效串联电阻(ESR):80Ω(ESR越小,振荡电路功耗越低、稳定性越强,80Ω属于26MHz贴片晶振的常规偏优水平);
  6. 工作温度范围:-40℃~+85℃(工业级宽温,可适应户外、车间等温差较大的场景)。

三、封装与物理特性

采用SMD3225-4P封装,物理尺寸为3.2mm×2.5mm×0.8mm(长×宽×高),4引脚贴片结构,适配SMT自动化生产流程,可直接贴装于PCB板,无需额外插件工序。该封装体积小巧,能有效节省设备内部空间,适合智能穿戴、物联网模块等小型化产品设计。

四、典型应用场景

TAXM26M4RCBCCT2T因性能适配性强,广泛应用于以下领域:

  1. 通信设备:蓝牙4.0/5.0模块、WiFi 2.4G模块的时钟基准(26MHz是此类模块的标准参考频率);
  2. 消费电子:智能手表、蓝牙耳机、智能家居网关的核心时钟源;
  3. 工业控制:PLC模块、传感器节点、小型工业仪器的频率基准(宽温特性适配车间环境);
  4. 物联网设备:低功耗LoRa模块、NB-IoT终端的时钟同步(无源设计降低模块功耗);
  5. 车载辅助系统:部分车载胎压监测、倒车雷达模块的时钟参考(满足车载级温度要求)。

五、性能优势与可靠性

  1. 宽温稳定性:-40℃~+85℃的工作范围覆盖工业级应用场景,避免极端温度下频率漂移导致的设备故障;
  2. 成本可控:无源设计无需内置振荡电路,相比有源晶振成本降低30%~50%,适合批量生产;
  3. 小封装适配:SMD3225封装体积仅为传统插件晶振的1/5,满足小型化设备的空间需求;
  4. 振荡稳定性:80Ω的低ESR确保振荡电路功耗低、抗干扰能力强,减少信号抖动;
  5. 易集成性:4引脚贴片结构适配主流SMT生产线,无需特殊焊接工艺,集成难度低。

六、使用注意事项

为确保产品性能稳定,需注意以下要点:

  1. 负载电容匹配:必须外接总负载电容9pF,建议在晶振XTAL1、XTAL2引脚各并联4.5pF陶瓷电容(误差≤±5%),避免频率偏差超出规格;
  2. 振荡电路驱动:需匹配外部MCU/ASIC的振荡模块,确保驱动能力(通常要求驱动电流≥1mA)与ESR匹配;
  3. PCB布局规范:晶振附近避免高频干扰源(如射频电路),走线长度≤5mm,接地良好,减少寄生电容影响;
  4. 焊接工艺:SMT焊接温度需控制在260℃以内(峰值温度≤260℃,持续时间≤10s),避免热应力导致晶振参数漂移;
  5. 存储条件:常温干燥环境(温度25℃±5℃,湿度≤60%)存储,避免静电损伤(无源晶振抗静电能力≤2kV,需做好ESD防护)。

该型号综合性能均衡,可满足多数常规电子设备的时钟基准需求,是小批量定制与批量生产的高性价比选择。

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
