X49SM24MSD2SC 产品概述
一、产品简介
X49SM24MSD2SC 是 YXC（扬兴科技）出品的一款无源贴片晶振，标称频率 24.000 MHz，封装为 HC-49S-SMD，适用于各类精确时钟源需求的嵌入式控制与通信设备。产品经工厂筛选，常温标称频差 ±20 ppm，综合频率稳定度在工作温度范围内为 ±30 ppm，工作温度 -20℃～+70℃。
二、主要特点
- 无源（被动）设计，需外接倒相器或振荡器电路驱动，兼容多种 MCU/ASIC 晶体振荡输入。
- 频率稳定、初始频差小（±20 ppm），适合对频率精度有较高要求的系统。
- 设计用于 SMD 贴装，便于自动化生产，封装为 HC-49S-SMD，机械强度与焊接可靠性良好。
- 指定负载电容 20 pF，便于与常见晶体振荡器电路匹配。
三、电气参数与规格
- 类型：无源贴片晶振（SMD）
- 频率：24.000 MHz
- 常温频差：±20 ppm（25℃ 基准）
- 负载电容（CL）：20 pF
- 频率稳定度（工作温度范围）：±30 ppm
- 工作温度：-20℃ ～ +70℃
- 封装：HC-49S-SMD
- 品牌/型号：YXC 扬兴科技 / X49SM24MSD2SC
四、应用与电路建议
- 典型应用：微控制器系统时钟、数字信号处理、通信模块、消费电子与工业控制等。
- 晶体为无源器件，需与外部放大器/倒相器（如 MCU 内置振荡器或专用晶体振荡器 IC）配合使用。
- 负载电容匹配：满足 CL = (C1·C2)/(C1+C2) + Cstray。若取 C1 = C2 = C，则 C ≈ 2×(CL − Cstray)。以常见 PCB 寄生电容 Cstray ≈ 2–5 pF 为例，推荐取 C1=C2 ≈ 30–36 pF；实际可根据目标电路与器件手册微调。
- 布局要点：晶体与 MCU 引脚距离应尽量近（走线尽量短），两端接线保持对称，避免与高频、高电流信号线并行，靠近地平面铺铜并做好接地返流路径以降低噪声耦合。
五、封装与焊接建议
- HC-49S-SMD 为适配表贴工艺的封装，可采用回流焊工艺贴装。请按照厂家提供的回流温度曲线或 JEDEC 标准工艺进行焊接，以免影响晶体性能。
- 贴装过程中避免强烈机械应力和长时间高温；焊后建议进行必要的去湿处理与功能测试。
六、质量与测试
- 产品出厂通常经频率、振幅与外观检验，建议在最终应用中进行上电后频率确认与老化测试。
- 对于对频率漂移极端敏感的应用，建议进行温度循环测试和长期老化评估。
七、订购信息与注意事项
- 完整型号：X49SM24MSD2SC，品牌：YXC 扬兴科技。下单时请确认频率、CL 与封装以避免型号混淆。
- 使用前请参考目标 MCU 或振荡器 IC 的应用手册，按照推荐的负载电容与 PCB 布局进行设计，以确保最佳振荡启动性与频率精度。

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.
