X3225192MOB4SI 产品概述
一、产品简介
X3225192MOB4SI 是一款无源贴片晶振（SMD3225-4P 封装），标称频率 19.2MHz，负载电容 12pF，常温频差 ±10ppm，频率稳定度 ±20ppm，工作温度范围 -40℃ 至 +85℃。该器件由 YXC 扬兴科技生产，适用于对中等精度时钟源有工业级温度要求的各类电子产品。
二、主要特性
- 无源晶体，需配合外部振荡器电路（如 Pierce 或 CMOS 反相器）使用；
- 频率：19.2MHz，常温频差 ±10ppm；
- 负载电容：12pF，推荐在电路中匹配对称负载电容；
- 频率稳定度（含温度与老化等）：±20ppm；
- 工作温度：-40℃ ~ +85℃（工业级）；
- 小型 SMD3225（3.2 × 2.5 mm）封装，适合高密度贴片工艺。
三、典型应用
- 嵌入式微控制器时钟源与通信接口基准（串口、以太网 PHY 等）；
- 网络与通信设备、路由器、交换机参考时钟；
- 工业控制、测量仪器与自动化设备；
- 消费电子与物联网终端等需要稳定时基的场合。
四、使用与设计注意事项
- 无源晶振需外接振荡电路工作，常用拓扑为 Pierce 振荡器或专用晶体振荡器芯片；
- 负载电容匹配：推荐采用对称电容 C1 = C2，根据公式 CL = (C1·C2)/(C1+C2) + Cstray 计算。若假定 PCB 寄生电容 Cstray ≈ 2–3pF，则可选 C1=C2≈18–22pF；
- 布局建议：晶振紧靠振荡器输入脚放置，引线最短，避免穿越敏感信号线；在晶振附近保留连续的接地平面，并使用过孔进行接地回流；
- 针对电磁干扰，要避免将高速信号或大电流回路布置在晶振附近。
五、可靠性与封装及焊接
- 封装：SMD3225-4P（3.2×2.5 mm），适配自动贴片生产线；
- 焊接：支持标准无铅回流焊工艺，请参照 JEDEC/J-STD 标准回流温度曲线，避免超过器件最高耐温时间积分；
- 建议做好静电防护与储存管理，保持湿敏等级（MSL）要求，防止受潮回流焊时产生缺陷。
六、采购与质量保证
- 品牌：YXC 扬兴科技，具有量产稳定性与可追溯的品质控制；
- 包装形式：常见卷盘包装（Tape & Reel），便于 SMT 线自动贴装；
- 若用于关键系统或大批量应用，建议与供应商确认批次样品进行长期漂移、温度循环和寿命验证。
如需更详细的电气等效参数（等效电阻、负载曲线、老化率及回流焊具体曲线）或样品测试数据，可提供产品数据手册或联系供应商技术支持以获得完整规范。

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.
