TAXD32768K2BGDAZT2T 直插石英晶振产品概述

一、产品基本定位

TAXD32768K2BGDAZT2T是雅晶鑫(YJX)推出的32.768kHz直插石英晶振,采用DT-26标准插件封装,专为需要稳定低频时钟信号的电子设备设计,核心定位是低成本、高可靠性的实时时钟(RTC)及低频振荡应用方案,适配消费电子、工业控制、物联网等多领域场景。

二、核心参数与性能解析

该晶振的关键参数经过针对性优化,精准匹配主流MCU和RTC模块的时钟需求:

  1. 频率基准:核心频率为32.768kHz(2¹⁵Hz),是RTC应用的标准频率——经15级二分频后可直接输出1Hz秒信号,无需额外复杂分频电路;
  2. 精度表现:常温(25℃左右)频差±20ppm,换算为时间误差约0.72秒/小时,满足日常时钟显示、数据时间戳的精度要求;
  3. 温度稳定性:全工作温度范围(-20℃~+70℃)内频率稳定度±30ppm,覆盖消费电子(手机、智能手表)、工业控制(PLC)及车载常温环境的温度需求;
  4. 负载电容:标准值12.5pF,与STM32、ATmega等主流MCU的RTC引脚负载电容天然匹配,减少外围电路调试成本;
  5. 启动可靠性:等效串联电阻(ESR)≤40kΩ,确保振荡电路易启动(低ESR是晶振稳定振荡的关键),长期工作无启动失败风险;
  6. 封装适配:DT-26直插封装,引脚间距符合插件工艺规范,支持手工焊接及自动化插件生产,无需特殊工装。

三、典型应用场景

32.768kHz是低频时钟的黄金频率,TAXD32768K2BGDAZT2T的参数特性使其在以下场景广泛适用:

  1. 消费电子RTC:智能手表、计算器、电子闹钟等设备的实时时钟模块,提供精准时间基准;
  2. 工业控制设备:PLC(可编程逻辑控制器)、工业传感器节点的时钟同步,确保数据采集时间戳准确;
  3. 通信辅助时钟:基站、路由器等通信设备的辅助时钟(配合高频晶振实现同步),降低系统整体功耗;
  4. 车载时钟:车载中控屏、仪表盘的时间显示,工作温度范围(-20~+70℃)满足车载舱内常温环境;
  5. 物联网终端:智能家居传感器(温湿度、门窗传感器)、智能门锁的低功耗时钟,延长设备续航时间。

四、使用注意事项

为确保晶振性能稳定,使用时需注意以下细节:

  1. 外围电容匹配:需在晶振引脚与地之间并联两个电容(总负载电容为12.5pF,通常采用两个22pF或18pF电容,具体需参考MCU datasheet调整);
  2. 焊接工艺:直插封装焊接温度建议控制在260℃以内(单引脚焊接时间≤3秒),避免高温损坏晶体内部结构;
  3. 环境防护:远离强电磁干扰源(如高频变压器、电机),防止频率偏移;存储时置于干燥环境(湿度≤60%),避免机械振动;
  4. 低功耗适配:若用于STM32L等低功耗MCU的RTC,需确认晶振启动电流(≤1mA)符合系统低功耗要求。

五、产品优势总结

相较于同类陶瓷谐振器,TAXD32768K2BGDAZT2T的核心优势在于:

  • 频率稳定性更高:石英晶体材质的长期漂移量远低于陶瓷谐振器,适合对时间精度要求较高的场景;
  • 封装兼容性好:DT-26直插封装适配多数传统电子设备的插件工艺,无需更换PCB设计即可替换升级;
  • 成本可控:作为雅晶鑫主流型号,供货稳定且价格亲民,适合批量生产;
  • 温度适应性强:-20~+70℃的工作范围覆盖多数民用及工业场景,无需额外加温控成本。

该晶振凭借精准的低频时钟输出、可靠的稳定性及广泛的适配性,成为电子设备RTC模块的高性价比选择。

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
