T32251352127MDBDE2X 产品概述

一、产品简介

T32251352127MDBDE2X 是雅晶鑫(YJX)出品的一款贴片晶振,封装为 SMD 3225-4P,设计用于对频率精度和稳定性有较高要求的电子产品。标称频率为 13.52127 MHz,适配 10 pF 负载电容,常温(室温)频差为 ±10 ppm,总体频率稳定度可达 ±30 ppm,工作温度范围为 -30 ℃ 至 +85 ℃,等效串联电阻(ESR)为 60 Ω。该器件为国产化产品,适合批量贴装与自动化生产。

二、主要技术参数

  • 型号:T32251352127MDBDE2X
  • 品牌:YJX(雅晶鑫)
  • 晶振类型:贴片晶振(SMD)
  • 封装:3225-4P(3.2 mm × 2.5 mm)
  • 频率:13.52127 MHz
  • 负载电容(CL):10 pF
  • 常温频差:±10 ppm(25 ℃)
  • 频率稳定度(含温度影响):±30 ppm
  • 等效串联电阻(ESR):60 Ω
  • 工作温度:-30 ℃ ~ +85 ℃
  • 包装形式:适用于 SMT 贴片机的带卷(Tape & Reel,具体请咨询供应商)

三、典型特性与优势

  • 高频点稳定:13.52127 MHz 为靠近 13.56 MHz 的精确频率,适合对频率精度要求高的近场通信与感应类应用。
  • 高精度起振:常温频差 ±10 ppm,适配要求严格的时钟与通信系统。
  • 宽温度范围:-30 ℃ 至 +85 ℃ 的工作温度覆盖大多数工业与消费应用环境。
  • 封装小巧:3225 小型 SMD 封装,适合空间受限的 PCB 布局并支持高速贴装生产线。
  • 良好兼容性:标准负载电容 10 pF,便于与主流 MCU/ASIC 的晶振电路搭配。

四、典型应用场景

  • NFC / RFID 近场通信设备(读卡器、智能卡模块)
  • 无线感应、短距通信模块和智能家居终端
  • 工业和消费类电子中的时钟源、振荡器参考频率
  • 微控制器(MCU)、数字信号处理器(DSP)或专用集成电路的外部晶体振荡器
  • POS 终端、门禁系统、智能表计等对频率稳定性有要求的设备

五、封装与 PCB 设计建议

  • 封装尺寸:3225(3.2 × 2.5 mm),建议参考制造商的封装图与焊盘推荐尺寸以确保可靠贴装与回流焊接。
  • 焊盘与接地:晶振本体对地板并无直接电极连接要求,但周围信号走线应保持清洁,尽量靠近 MCU 的晶振输入引脚放置以减少走线寄生电容和干扰。
  • 晶振负载电容配置:晶体通常需要两侧各接一只负载电容(对地)。理论上当两侧电容相等时,CL ≈ C/2 + Cs(Cs 为电路寄生电容,典型 2–5 pF)。若以 Cs ≈ 2.5 pF 估算,建议每侧使用约 15 pF(C ≈ 2 × (CL - Cs) ≈ 15 pF)。实际选型请根据 PCB 寄生电容与电路调试结果微调。
  • 对 EMI 的注意:晶振附近应避免强电流回路和高速信号线。必要时在晶振与 MCU 之间加入小屏蔽或地线隔离。

六、安装与使用建议

  • 回流焊:建议参照供应商的焊接曲线与说明进行回流,避免超过推荐温度与时间以确保性能与可靠性。
  • 储存与防潮:未说明具体等级时,建议按一般 SMD 元件防潮措施处理,长期存放可密封防潮并在贴片前进行防潮烘烤(参考元件出厂建议)。
  • 启动与驱动:晶体启动性能受 ESR、外围电路驱动能力影响。ESR 为 60 Ω 时,确保所用振荡器电路能在该 ESR 下可靠起振;若出现起振缓慢或不稳定,请检查外围负载电容、供电滤波和布线。
  • 调试:在系统调试时优先监测实际振荡频率和启动时间,并根据需要微调负载电容或软件时钟校准以满足精度需求。

七、选型与注意事项

  • 若系统对频率精度和温度漂移有更高要求,可向供应商索取更高稳定度等级或温度补偿方案(TCXO)比较。
  • 确认 ES R 与目标振荡器前端的匹配,避免因 ESR 过高导致无法起振。
  • 在高振幅或强电磁环境下,请评估晶振长期可靠性与相位噪声要求,必要时选用具有更好相位噪声特性的件。

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
