TAXD32768K2CRDBZT2S 石英晶体谐振器产品概述
一、产品基本定位
TAXD32768K2CRDBZT2S是雅晶鑫（YJX）推出的直插式石英晶体谐振器，核心频率为32.768kHz——该频率是全球通用的实时时钟（RTC）基准频率（因2¹⁵=32768，可通过简单分频直接得到1Hz秒信号），主打“高精度+宽温适应性+易集成”特性，适配需要精准时间计数、低功耗时钟基准的消费电子、小型工业控制等场景。
二、核心技术参数深度解析
1. 频率特性与精度
- 标准频率：32.768kHz，是RTC领域的黄金频率，既满足秒级精准计数需求，又因频率低、功耗可控，适配低功耗电路设计；
- 常温频差：±20ppm（25℃环境下），换算为频率偏差为0.65536Hz，每小时时间偏差约2.36秒，远低于大多数应用的可接受范围；
- 全温区稳定度：±30ppm（-20℃~+70℃），最大频率偏差0.98304Hz，保障设备在不同环境温度下的时钟稳定性。
2. 负载电容与ESR
- 负载电容：6pF，为谐振器工作时需外接的等效电容值，低负载设计可简化外接电路，适配小型化PCB布局；
- 等效串联电阻（ESR）：30kΩ，是谐振器内阻的关键指标，30kΩ为该频率段的典型合理值，既保证电路快速起振，又避免功耗过高。
3. 工作温度范围
支持-20℃~+70℃，覆盖室内外消费电子（如智能手环）、小型工业设备（如定时传感器）的使用环境，无需额外温控措施。
三、封装与物理特性
产品采用DT-38直插封装，具备以下优势：
- 引脚类型：2引脚直插式（DIP），符合标准规范，便于手工焊接或基础自动化焊接，无需复杂贴片工艺；
- 尺寸紧凑：属于小型化直插封装，适配PCB板紧凑布局，适合小型化产品设计；
- 封装材料：耐温抗振动塑料封装，可承受260℃焊接温度，同时具备一定抗环境干扰能力。
四、典型应用场景
- 实时时钟（RTC）模块：智能手表、家用电子钟、智能门锁的时间基准，保障时间精准显示；
- 低功耗消费电子：智能手环、运动手表、计算器的时钟电路，适配设备低功耗需求；
- 小型工业控制：定时浇水控制器、无线传感器节点的时钟同步，保障数据时间戳精准；
- 通信辅助电路：LoRa节点、蓝牙低功耗设备的辅助时钟，用于待机时的时间同步。
五、品牌与可靠性保障
雅晶鑫（YJX）作为国内石英晶体元器件专业品牌，该产品经过多项可靠性测试：
- 焊接可靠性：可承受260℃波峰焊/回流焊，无封装开裂、引脚脱落问题；
- 老化筛选：每批次经老化测试，保证参数一致性与长期稳定性；
- 环境适应性：符合常规振动、冲击标准，适应一定的环境振动场景。
产品参数标注清晰，可直接匹配电路设计，适合批量采购应用。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
