TAXM8.192M4QLDDDT2T贴片晶振产品概述

一、产品基本定位与核心参数

TAXM8.192M4QLDDDT2T是雅晶鑫(YJX)推出的一款工业级SMD5032-4P封装贴片晶振,专为需要稳定时钟信号的中低端电子设备设计,核心参数明确且适配性强:

  • 固定频率:8.192MHz(因$2^{13}=8192$,天然适配二进制时钟、数据存储同步等场景);
  • 精度指标:常温频差$\pm20\mathrm{ppm}$、全温频率稳定度$\pm20\mathrm{ppm}$(满足多数非超高精度需求);
  • 负载电容:20pF(与主流MCU/FPGA的晶振接口匹配度高);
  • 电气特性:等效串联电阻(ESR)$\leq80\Omega$(降低起振难度与功耗);
  • 温度范围:$-30^\circ\mathrm{C} \sim +85^\circ\mathrm{C}$(覆盖多场景环境)。

二、封装与物理特性

该晶振采用SMD5032-4P标准贴片封装(尺寸:$5.0\mathrm{mm}\times3.2\mathrm{mm}\times1.2\mathrm{mm}$),四引脚设计,符合表面贴装工艺要求:

  • 封装材质:耐高温抗干扰工程塑料,可承受回流焊高温;
  • 引脚工艺:镀锡处理,提升焊接可靠性,避免长期氧化;
  • 集成优势:体积小巧,无需额外支架,直接集成到PCB板,节省布局空间。

三、性能优势解析

  1. 精度与成本平衡:$\pm20\mathrm{ppm}$的精度无需为过高精度支付溢价,同时避免因频率漂移导致的通信延迟、计时误差(如8.192MHz漂移仅$\leq0.16384\mathrm{Hz}$);
  2. 负载电容适配性:20pF是STM32、ESP32等主流主控芯片推荐值,无需外接额外匹配电容,简化电路设计;
  3. 低ESR提升可靠性:80Ω的ESR远低于入门级晶振(通常$\geq100\Omega$),可降低振荡电路驱动电流(减少发热),且起振速度快(通电后数毫秒内稳定输出)。

四、环境适应性说明

工作温度范围$-30^\circ\mathrm{C} \sim +85^\circ\mathrm{C}$,覆盖了大部分设备的使用场景:

  • 室内设备:智能音箱、机顶盒(常温$\pm20^\circ\mathrm{C}$);
  • 户外设备:安防摄像头(冬季$-20^\circ\mathrm{C}$、夏季$+70^\circ\mathrm{C}$);
  • 工业设备:小型PLC、传感器模块(车间环境);
    全温范围内频率稳定度保持$\pm20\mathrm{ppm}$,极端温度下仍能满足基本计时与同步需求。

五、典型应用领域

因参数适配性强,该晶振广泛用于:

  • 消费电子:路由器、智能门锁的时钟同步;
  • 通信模块:蓝牙/WiFi模块的载波参考;
  • 工业控制:小型传感器节点、PLC辅助计时;
  • 汽车电子:车载USB充电器、仪表盘辅助时钟(非安全关键系统);
  • 物联网设备:低功耗环境监测仪的时钟源。

六、选型与使用注意事项

  1. 电路匹配:确认主控芯片晶振接口负载电容为20pF(若芯片内部已集成匹配电容,无需外接);
  2. 焊接规范:回流焊峰值温度$\leq260^\circ\mathrm{C}$、时间$\leq10$秒,避免高温损坏晶振;
  3. 存储条件:未使用晶振存放在湿度$\leq60%$的干燥环境,防止引脚氧化;
  4. 抗干扰设计:晶振电路远离高频信号线、电源模块,可通过接地屏蔽提升稳定性。

该晶振以“稳定可靠、成本可控”为核心优势,是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
