TAXM40M4ZCBCDT2T无源贴片晶振产品概述

一、产品基本信息

TAXM40M4ZCBCDT2T是雅晶鑫(YJX)推出的无源石英贴片晶振,属于工业级宽温型时钟源器件。作为无源晶振,该产品无内置振荡电路,需外接匹配电容与MCU/ASIC等芯片的振荡模块配合,实现精准时钟信号输出。封装采用SMD2016-4P(2.0mm×1.6mm尺寸、4引脚贴片封装),体积紧凑,适配高密度PCB设计,支持自动化SMT贴装,生产效率高。

二、核心性能参数解析

该晶振的关键参数针对中高频时钟需求优化,具体特性如下:

  1. 标称频率:40MHz,覆盖主流MCU、通信模块的时钟区间,无需额外分频即可直接驱动多数低功耗系统(如BLE、WiFi子模块);
  2. 常温频差:±20ppm,即25℃下实际频率与40MHz的偏差为±800Hz(计算:40×10⁶Hz ×20×10⁻⁶=800Hz),精度满足工业、消费电子的常规时钟要求;
  3. 负载电容:9pF,为外接匹配电容的推荐值(通常需在晶振引脚与地之间并联两个9pF电容),与多数MCU内部负载电容匹配,可优化振荡稳定性;
  4. 频率稳定度:±20ppm,指温度变化(-40℃~+85℃)、电源波动下的频率漂移范围,与常温频差一致,说明温度系数优异,宽温场景下频率偏差极小;
  5. 等效串联电阻(ESR):40Ω,属于无源晶振的合理范围,ESR越低振荡裕量越大,40Ω可确保宽温、负载变化时仍能稳定起振。

三、封装与引脚配置

采用SMD2016-4P贴片封装,尺寸仅2.0mm(长)×1.6mm(宽)×0.6mm(厚,典型值),比传统DIP封装体积缩小60%以上,适合小型化设备(如可穿戴、智能传感器)。4引脚配置为标准无源晶振封装,其中2个引脚为振荡信号输入/输出端,另外2个引脚可作为接地端或空脚(具体需参考雅晶鑫官方 datasheet),适配主流PCB布线,支持自动化贴装。

四、环境适应性与可靠性

  1. 工作温度范围:-40℃~+85℃,覆盖工业级温度区间,可稳定工作于户外、车载、车间等极端温度场景(如冬季低温、夏季高温);
  2. 可靠性验证:产品经过高低温循环(-40℃+85℃循环100次)、湿度测试(85℃/85%RH 1000小时)、振动测试(102000Hz,1.5g加速度)等严苛验证,符合GB/T 14864-2017石英晶振标准;
  3. 环保合规:满足RoHS 2.0与REACH法规要求,无铅、汞、镉等有害物质,适配全球市场环保需求。

五、典型应用场景

TAXM40M4ZCBCDT2T的参数特性使其适用于以下场景:

  1. 工业控制设备:PLC模块、工业传感器、电机控制器,宽温与稳定频率确保恶劣工况下精准运行;
  2. 车载电子:仪表盘、ADAS辅助系统、车载通信模块,满足车载环境的温度与振动要求;
  3. 消费电子:智能手环、蓝牙耳机、小型智能家居设备,小体积与低功耗适配便携需求;
  4. 通信模块:低功耗蓝牙(BLE)、WiFi 4/5子模块,40MHz频率直接驱动射频芯片时钟;
  5. 医疗电子:小型监护仪、血糖监测仪,稳定频率确保医疗数据采集准确性。

六、品牌与优势总结

雅晶鑫(YJX)作为国内石英晶振专业厂商,TAXM40M4ZCBCDT2T继承了品牌“高稳定性、宽温适应性、小体积”的核心优势:无源晶振无内置电路,寿命长达10万小时以上;40MHz频率覆盖主流应用,无需额外分频;SMD2016-4P封装适配高密度设计,是工业、车载、消费电子等领域的高性价比时钟源选择。

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
