TAXM8M4QLDCDT2T无源贴片晶振产品概述

一、产品基本信息

TAXM8M4QLDCDT2T是雅晶鑫(YJX)品牌推出的无源贴片晶振,属于小型化晶体谐振器范畴。该产品采用SMD5032-4P封装,无需外部供电即可通过外接匹配电容实现稳定振荡,核心定位为各类电子设备的基础时钟参考源。

二、核心电气参数解析

该晶振的参数直接决定其性能边界与适用场景,关键参数如下:

  • 频率规格:固定振荡频率为8MHz,是电子设备中最常用的基础时钟频率(适配微控制器、通信模块等主流芯片的时钟输入);
  • 常温频差:±20ppm(百万分之一),常温下(25℃左右)频率偏差仅±160Hz(计算方式:8MHz×20×10⁻⁶),满足多数消费电子、工业设备的精度要求;
  • 负载电容:推荐20pF,无源晶振需外接等效20pF的电容(通常PCB并联两个10pF电容),以保证振荡频率与标称值一致;
  • 等效串联电阻(ESR):100Ω,属于无源晶振的低阻范围,低ESR可降低振荡电路功耗,提升抗干扰能力与稳定性;
  • 频率稳定度:±30ppm,包含温度变化、电源波动等因素的总偏差,结合-40℃~+85℃的工作温度,覆盖宽温环境下的稳定工作;
  • 工作温度范围:-40℃至+85℃,符合工业级与车载级环境要求,适应高低温复杂场景。

三、封装与物理特性

TAXM8M4QLDCDT2T采用SMD5032-4P封装,其中“5032”代表封装尺寸(近似5.0mm×3.2mm,具体高度参考厂商 datasheet),“4P”为4引脚贴片结构,具备以下优势:

  1. 体积紧凑:适配智能手环、蓝牙耳机等小型化设备的PCB布局,节省空间;
  2. 自动化适配:贴片式设计支持SMT自动化焊接,提升生产效率;
  3. 抗扰性强:SMD封装焊接牢固,抗振动、抗冲击性能优于插件晶振,适合移动或工业振动环境。

四、典型应用场景

结合参数特性,该晶振的典型应用覆盖:

  • 消费电子:智能手表、便携式游戏机、蓝牙耳机的时钟源(利用小体积与宽温特性);
  • 工业控制:PLC、传感器模块、工业机器人的定时电路(依赖宽温与稳定度);
  • 通信设备:路由器、蓝牙/WiFi模块的参考时钟(8MHz为通信芯片常见基准);
  • 车载电子:车载导航、行车记录仪、汽车传感器的时钟电路(符合-40~+85℃宽温要求);
  • 物联网设备:智能家居终端、无线传感器节点的时钟同步(低功耗、小体积适配物联网场景)。

五、性能特点总结

该晶振的核心优势可归纳为:

  1. 宽温稳定:-40℃~+85℃覆盖绝大多数使用环境,无需额外温控;
  2. 精度可靠:常温±20ppm、总稳定度±30ppm,满足多数场景时钟需求;
  3. 低阻高效:100Ω ESR降低电路功耗,提升振荡稳定性;
  4. 小型化设计:SMD5032-4P封装适配各类微型设备;
  5. 无源易集成:无需外部电源,仅需外接匹配电容即可工作,简化电路设计。

六、使用注意事项

  1. 负载电容匹配:必须外接等效20pF的电容(如两个10pF并联),避免频率偏差;
  2. PCB布局:晶振附近远离高频干扰源,电容需靠近引脚焊接,减少寄生电容;
  3. 焊接温度:控制焊接温度≤260℃,时间≤10秒,避免损坏内部晶体结构。

该产品凭借稳定的性能与小型化设计,成为中低端电子设备时钟源的高性价比选择。

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
