TAXM38.4M4ZCBDDT2T 贴片晶振产品概述

一、产品定位与核心属性

TAXM38.4M4ZCBDDT2T是雅晶鑫(YJX)推出的工业级通用贴片晶振,主打「小体积、中精度、高适配性」,聚焦消费电子、工业控制、通信等领域的时钟基准需求。其核心属性可简化为:38.4MHz标称频率、SMD2016-4P超小封装、±10ppm常温频差,属于工业场景下的性价比时钟方案。

二、关键性能参数详解

1. 频率精度与稳定性

  • 标称频率:38.4MHz——常用的「分频友好型」中间频率,可轻松分频为19.2MHz、9.6MHz等下游设备常用频率,减少额外分频电路成本;
  • 常温频差:±10ppm(25℃环境)——实际输出频率与38.4MHz的偏差≤±384Hz(计算方式:38.4MHz×10ppm=384Hz),满足大多数设备对时钟同步的基本要求;
  • 温度频率稳定度:±20ppm(-30℃+85℃)——工作温度范围内,频率漂移不超过±768Hz,覆盖工业级温度区间(优于商业级0℃70℃),适配户外、车间等复杂环境。

2. 电路匹配参数

  • 负载电容:9pF——需注意为谐振电路负载电容(非串联电容),设计时需匹配该值以保证晶振稳定振荡(若电容偏差过大,可能导致频率偏移或停振);
  • 等效串联电阻(ESR):40Ω——常规贴片晶振的中低水平ESR,有助于提升谐振电路Q值(品质因数),减少功耗并降低频率抖动。

3. 环境与可靠性参数

  • 工作温度:-30℃~+85℃——工业级温度范围,可适应低温户外(如北方冬季)、高温车间(如注塑机旁)等场景;
  • 存储温度:-40℃~+125℃(雅晶鑫常规标准)——保障运输、仓储过程中晶振性能不受损。

三、封装与应用场景

1. 封装特点

SMD2016-4P封装尺寸为2.0mm×1.6mm×0.8mm(典型值),4脚贴片结构,支持自动化SMT贴装,能有效节省PCB空间(比常规2520封装小30%左右),适配智能手环、传感器节点等小型化设备。

2. 典型应用场景

  • 消费电子:智能穿戴(手环/手表的蓝牙模块时钟)、便携式音频(耳机解码时钟)、智能家居(智能插座控制时钟);
  • 工业控制:小型PLC、温湿度/压力传感器节点、工业LoRa网关;
  • 通信设备:NB-IoT终端、低功耗路由器(WiFi同步时钟)、4G模块辅助时钟;
  • 车载电子:非严苛车载子系统(如车载充电器控制时钟、后装导航辅助时钟)。

四、品牌与品质保障

雅晶鑫(YJX)作为国内石英晶振领域的成熟厂商,TAXM38.4M4ZCBDDT2T经过多项可靠性测试:

  • 高低温循环测试(-40℃~+85℃,100次循环);
  • 振动测试(10~2000Hz,加速度1g);
  • 冲击测试(1000g,1ms半正弦波);
  • 符合RoHS 2.0环保标准,无铅焊接兼容。

产品定位国内中低端市场,在保证基本精度与可靠性的前提下,降低设备时钟方案的BOM成本。

五、设计注意事项

  1. 电路需匹配9pF负载电容(建议使用0402封装陶瓷电容,误差≤5%);
  2. 晶振附近应远离射频电路、开关电源等高频干扰源,避免频率偏移;
  3. 焊接采用回流焊工艺,峰值温度≤245℃,过温时间≤10s(避免损坏晶振内部石英片)。

该产品通过平衡「精度、体积、成本」,成为工业与消费电子领域的通用时钟基准优选方案。

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
