T322532768MLBDE2X 产品概述

一、产品简介

T322532768MLBDE2X 是雅晶鑫(YJX)推出的一款全国产 SMD 贴片晶振,标准频率为 32.768MHz,采用 SMD3225-4P 封装设计,面向对频率精度和稳定性有较高要求的嵌入式电子系统。器件体积小、可靠性高,适合自动化贴装与回流焊工艺,满足消费类、工业类及通信类产品的时钟源需求。

二、主要技术参数

  • 频率:32.768MHz
  • 常温频差(初始容差):±10ppm
  • 频率稳定度(含温度与老化):±30ppm
  • 负载电容:20pF
  • 等效串联电阻(ESR):30Ω
  • 工作温度范围:-30℃~+85℃
  • 封装:SMD3225-4P(贴片)
  • 品牌:YJX(雅晶鑫)
  • 制造:全国产

三、关键特性与优势

  • 高精度:±10ppm 的常温频差可满足高精度时钟源需求,有利于降低系统累积时间误差。
  • 稳定可靠:±30ppm 的频率稳定度在常温及长期使用中表现良好,适用于对时间基准有长期稳定性要求的应用。
  • 适配性强:20pF 负载电容为常见值,与多数 MCU/振荡器输入电路兼容性良好。
  • 良好启动性能:30Ω 的 ESR 在多数晶体振荡器电路中能保证可靠起振与稳定振荡。
  • 工业温度范围:-30℃至+85℃,能够满足一般工业与户外环境下工作要求。
  • 贴片封装:SMD3225-4P 体积小,利于高密度 PCB 布局与自动化装配。

四、典型应用

  • 单片机/微控制器外部时钟源,用于系统主频或定时参考。
  • 通信设备本振(VCO 参考或本地振荡器)。
  • 精密测量、数据采集系统的时间基准。
  • 工业控制、仪器仪表及可穿戴设备等对体积与稳定性有要求的终端。

五、封装与焊接建议

  • 封装尺寸:SMD3225,适合 3225 焊盘设计。为确保焊接可靠性,建议遵循标准的回流焊温度曲线(无铅回流峰值温度通常为 245–260℃,但请参考具体晶振厂商工艺参数)。
  • PCB 布局:晶振器件应放置在 MCU 振荡引脚附近,焊盘与引线尽量短、直接。周围避免高频、高电流走线,靠近地平面以降低电磁干扰。
  • 负载电容:建议在晶振两端各并联一只贴片电容,实际电容值应根据 PCB 寄生电容(通常 2–5pF)和目标 CL=20pF 计算,推荐每侧电容约 18–22pF 的常见值并做实测微调。
  • 防护与存储:避免潮湿环境存放,建议防潮包装并在推荐的烘烤条件下进行贴装前处理(若需)。

六、使用注意事项

  • 校核兼容性:在设计前请确认目标振荡器电路能驱动 ESR=30Ω 的晶体,部分低功耗振荡器对 ESR 有严格要求。
  • 寿命与老化:晶体有微小老化效应,长期使用频率可能随时间缓慢漂移,设计时应留有足够裕量。
  • 温度影响:尽管在 -30~+85℃ 范围内工作,但温度极限附近频率可能出现偏移,关键应用请做温度补偿或筛选。
  • 防振动、防冲击:在高振动或冲击环境下,建议在结构上做加固与防护。

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
