T3225374MDBDE2X 产品概述
一、产品简介
T3225374MDBDE2X 是雅晶鑫（YJX）出品的一款贴片晶振，标准 SMD3225-4P 封装，标称频率 37.4 MHz。该器件为通用石英晶体元件，面向各类需要高精度时钟参考的电子系统，兼顾小型化与良好的频率稳定性，适合表贴自动化装配。
二、主要特性
- 晶振类型：贴片晶振（SMD）
- 频率：37.4 MHz
- 常温频差（25℃）：±10 ppm
- 频率稳定度（含温度漂移等）：±30 ppm
- 负载电容：10 pF（标称）
- 等效串联电阻（ESR）：30 Ω（典型/上限）
- 工作温度范围：-30 ℃ 至 +85 ℃
- 封装型号：SMD3225-4P（尺寸 3.2 × 2.5 mm）
这些特性使该晶振在中高频应用中具有良好的频率精度与抗干扰能力。
三、典型应用场景
- 无线通信模块、RF 前端本振参考
- 微控制器与数字系统的时钟源
- 精密测量、数据采集系统的定时参考
- 报警、遥测与工业控制设备
- 需要小体积及稳定时钟源的便携式电子产品
四、电气与匹配建议
- 负载电容要求为 10 pF，实际电路中通常在晶体两端各并联一只电容到地；考虑 PCB 板间寄生电容（2–5 pF），每侧电容可选在 15 pF 左右以获得接近标称负载。
- ESR 较大时会影响起振能力与驱动电平，建议在原理图设计阶段验证所用振荡器（或 MCU 内置振荡器）对该 ESR 的驱动能力，必要时选择驱动能力更强的振荡电路或外部放大器。
- 建议在晶体周围保持良好接地与屏蔽措施，避免靠近噪声源（高速数字线、开关电源等）。
五、封装与焊接注意事项
- SMD3225-4P 小体积适合回流焊流程，推荐按照制造商提供的焊接温度曲线（回流峰值温度与时长）进行焊接以保证可靠性。
- 贴片区应保证平整、焊盘尺寸与焊膏量合适，避免过多应力传递至晶体元件；回流后建议进行目视或 X 射线检查。
- 储存与搬运应避免机械冲击与静电放电，对环境湿度敏感时按照防潮湿包装要求处理。
六、质量与采购信息
- 品牌：YJX（雅晶鑫），国产供应，适合追求性价比且对频率精度有一定要求的项目。
- 在批量采购前建议索取样品并在目标电路中做上电、温漂与相位噪声等验证测试；如需更严格的频率稳定度或特殊温度区间，请咨询供应商定制或选择更高等级型号。
- 常见出货形态为带卷盘（Tape & Reel），便于贴片机直接贴装。
如需器件详细数据手册（包括封装尺寸图、焊接曲线、温度曲线与典型等效电路示意），可向雅晶鑫（YJX）索取完整技术资料以完成最终设计确认。

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.
