Y6OGC-STU-32.768K 产品概述

一、产品简介

Y6OGC-STU-32.768K 是 YXC(扬兴科技)出品的一款无源直插晶振,工作频率为 32.768 kHz,专为实时时钟(RTC)与低功耗计时应用设计。该器件采用 DT-26 直插封装,易于通孔安装与替换,适合需要稳定、低功耗时间基准的工业与消费类电子产品。

主要参数一览:

  • 标称频率:32.768 kHz
  • 常温频差:±10 ppm(室温校准/初始公差)
  • 频率稳定度:±30 ppm(在工作温度范围内)
  • 工作温度:-20 ℃ ~ +70 ℃
  • 负载电容:12.5 pF
  • 类型:无源晶振(直插/DT-26)
  • 品牌:YXC 扬兴科技

二、性能与特性

Y6OGC-STU-32.768K 作为标准的 32.768 kHz 石英晶体,具有以下明显特性:

  • 高频率稳定性:在指定工作温度范围内频率稳定度为 ±30 ppm,适合对时间精度有中高要求的 RTC 场景。
  • 低初始偏差:常温频差仅 ±10 ppm,便于出厂校准与系统级时间精度控制。
  • 低功耗适配:作为无源晶振,与微控制器内部振荡电路结合时可实现微瓦级的低功耗运行,适配电池供电设备。
  • 直插 DT-26 封装:便于手工焊接、波峰焊或插件式生产工艺,维护更换方便。

三、典型应用

  • 实时时钟(RTC)模块与计时器
  • 低功耗物联网终端、传感节点
  • 智能表计、抄表设备和数据记录仪
  • 消费电子:手持设备、遥控器等需精确计时的场景
  • 工业控制、仪器仪表中需要稳定时间基准的系统

四、设计与使用建议

  • Q:负载电容如何选择?
    A:晶体规格标注的等效负载电容 CL = 12.5 pF,系统上两侧的电容 C1、C2 与电路板走线电容(Cstray)共同决定实际负载。常用计算关系为: CL = (C1 × C2) / (C1 + C2) + Cstray 若取 C1 = C2,则近似有 C1 ≈ 2 × (CL − Cstray)。
    经验值:若板上寄生电容 Cstray ≈ 2–5 pF,建议两侧电容取 22 pF(或 18–22 pF 工艺上微调),以便达到 12.5 pF 的等效负载。

  • 布局建议:

    • 晶体与 MCU 的 XIN/XOUT 引脚之间走线应尽可能短且直接,避免旁路信号或高频信号并行。
    • 在晶体与微控制器之间的接地应尽量形成连续低阻抗地层,避免在晶体附近放置数字地分割或高速器件。
    • 两侧负载电容应尽量靠近 MCU 芯片引脚放置,减少走线长度与寄生电容不确定性。
  • 驱动与电平:
    无源晶体应搭配 MCU 内部的晶体振荡电路使用,推荐采用低驱动电平以延长晶体寿命并降低频率漂移。参考 MCU 厂家关于晶体驱动级别的建议进行配置。

五、安装与可靠性注意事项

  • 焊接工艺:DT-26 直插封装适合手工焊接或波峰焊装配。建议遵循厂家的焊接温度与时间规范,避免长时间高温暴露导致晶体性能退化。
  • 机械应力:避免在焊接或后续处理过程中对晶体本体施加弯曲或拉伸应力,焊接时应避免热冲击与过重的机械力。
  • 清洗与环境:若进行清洗作业,选择对石英晶体无腐蚀、无残留的清洗剂,避免高温烘烤或化学侵蚀。存储与使用环境应避免强烈振动和冲击。
  • 老化与漂移:长期使用中晶体会有微量老化引起的频率漂移,建议在设计时预留必要的频率裕度或通过软件定期校准 RTC。

六、选型与订购信息

  • 型号:Y6OGC-STU-32.768K
  • 封装:DT-26 直插封装(通孔)
  • 品牌:YXC 扬兴科技
  • 在选型时,请确认目标系统的温度范围与频率精度要求,若需更宽温度范围或更高稳定度,可与供应商沟通定制或筛选更高等级规格的石英。

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
