T20632768KGBBZ2X 产品概述

一、产品简介

T20632768KGBBZ2X 是雅晶鑫(YJX)推出的一款标准32.768 kHz 圆柱直插石英晶体,封装为 DT-26(圆柱直插 2*6 规格),专为低频时钟与实时时钟(RTC)电路设计。该器件以稳定的频率特性、适配常见负载电容值及宽工作温度范围,适合消费电子、工业监控与物联网等需要精确计时与低功耗的应用场景。

二、主要参数

  • 芯片型号:T20632768KGBBZ2X
  • 品牌:YJX(雅晶鑫)
  • 频率:32.768 kHz
  • 常温频差(25℃):±10 ppm
  • 频率稳定度(含温度、老化等):±20 ppm
  • 负载电容:12.5 pF
  • 等效串联电阻(ESR):40 kΩ
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装形式:DT-26 圆柱直插(2*6 规格)

三、产品优势

  • 高精度:常温频差 ±10 ppm,适合对时间计量要求较高的 RTC 与计时器应用。
  • 宽温适应:-40℃ 到 +85℃ 的工作范围,能满足工业级环境与户外设备的使用要求。
  • 低功耗配套:32.768 kHz 为典型低频时钟频率,配合低功耗微控制器可实现长时间待机。
  • 良好驱动适配性:40 kΩ 的等效串联电阻(ESR)适配多数低频振荡电路,兼容常见的 MCU 内部振荡器驱动能力。
  • 直插封装便于手工焊接、快速原型验证与批量生产装配。

四、典型应用

  • 实时时钟(RTC)模块与时钟基准
  • 可穿戴设备、电子表与便携式终端
  • 工业控制与数据记录仪器
  • 智能表计、远程传感器节点与物联网终端
  • 低功耗微控制器的外部时钟源

五、使用建议与注意事项

  • 振荡电路匹配:采用两端对称负载电容时,建议选取 C1 = C2 ≈ 18–22 pF(考虑 PCB 寄生电容约 2–5 pF),以实现器件标称负载 12.5 pF。实际电容值应结合板上寄生容抗与 MCU 振荡器要求微调。
  • 布线建议:晶体应尽量靠近 MCU 的 XTAL/RTC 引脚放置,两引脚到晶体的走线尽量短且对称,避免穿越高频或开关型信号线;若条件允许,晶体周围布置接地平面以降低干扰。
  • 驱动与启动:确认目标 MCU 或振荡器电路的驱动能力适配本晶体的 ESR 与启动要求;若使用内部自带振荡器,请参考 MCU 数据手册对外部晶体的要求。
  • 焊接与机械应力:DT-26 直插封装适合波峰或手工焊接,但应避免长时间高温加热及对晶体主体施加机械应力。手工焊接时建议快速焊接,焊点冷却后避免弯折引脚。
  • 存储与安装:避免长期潮湿、高温或强振动环境;在装配过程中避免与腐蚀性气体接触。

六、订购信息与包装

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
