TX206D32768K2GAAZ2S 产品概述
一、产品简介
TX206D32768K2GAAZ2S 为 YJX（雅晶鑫）生产的直插式32.768kHz石英晶体，采用圆柱形直插封装（DT-26），引脚间距标注为2*6。此系列专为低功耗实时时钟（RTC）、便携式设备和计时应用设计，在典型环境下提供高精度、长时间稳定的时基参考。
二、主要特性
- 标称频率：32.768 kHz，便于二进制分频为1Hz时钟信号。
- 常温频差（25°C）：±5 ppm，适合对初始频率精度要求较高的场景。
- 频率稳定度（含温度、老化等）：±10 ppm，保证整机长期计时误差受控。
- 负载电容：12.5 pF（标称），便于与典型MCU内部振荡驱动匹配。
- 等效串联电阻（ESR）：40 kΩ，适配低驱动电流的RTC振荡电路。
- 工作温度范围：-10°C ～ +60°C，覆盖多数室内与消费类产品应用场景。
- 封装：DT-26 圆柱直插，便于穿孔安装和波峰/手工焊接。
三、技术参数（摘要）
- 频率：32.768 kHz
- 常温频差：±5 ppm
- 频率稳定度：±10 ppm（工作温度范围内）
- 负载电容：12.5 pF
- ESR：40 kΩ
- 工作温度：-10°C ～ +60°C
- 封装：DT-26，圆柱直插，2*6 引脚布局
- 品牌：YJX（雅晶鑫）
四、典型应用
- 单片机/微控制器的RTC振荡器（手表、计时器、数据记录器）
- 低功耗便携设备（医疗监测、遥控器、物联网终端）
- 消费电子的时钟与闹钟模块
- 需要长期稳定计时的工业控制系统（在指定温度范围内）
五、封装与安装建议
- 该产品为直插（Through-Hole）圆柱封装，适合穿孔板或波峰/手工焊接安装。
- 与微控制器形成振荡回路时，应在晶体两端接入两只负载电容以形成所需负载电容值。计算每只电容参考公式：C_each ≈ 2×CL − Cstray（CL 为标称负载电容，Cstray 为电路板与芯片输入电容），以保证实际并联负载接近12.5 pF。
- 由于较高的ESR，选择驱动能力匹配的MCU振荡器，确保启动可靠且驱动电流在晶体允许范围内。
六、使用注意事项与选型建议
- 温度范围为-10°C ～ +60°C，若应用在更严苛环境（低温或高温），建议选用更宽温度等级的晶体。
- 常温频差±5 ppm 与整体频率稳定度±10 ppm 是分别描述初始误差与工作范围内变化，设计时间基准时应同时考虑。
- 装配时注意避免机械应力直接作用于晶体体壳和引脚，防止频率漂移或损伤。
- 对焊接工艺敏感时，建议参考厂商焊接温度曲线与预热要求，以保证长期可靠性。
总结：TX206D32768K2GAAZ2S 提供了高精度、低功耗、易安装的32.768kHz时基解决方案，适合大多数消费与工业级RTC应用。在选型与电路设计时，重点关注负载电容匹配与振荡器驱动能力，以获得最佳启动性能与长期计时稳定性。

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.
