X49SD8MSB2SC 产品概述
一、产品简介
X49SD8MSB2SC 是 YXC（扬兴科技）出品的一款无源直插晶振，工作频率为 8.000 MHz，封装为常见的 HC-49S 直插金属封装。该器件为被动晶体谐振器，需要与外部振荡电路（如反相器或 MCU 内部放大器）配合使用，适合对尺寸、成本和频率精度有要求的通用电子设备。
二、主要特性
- 频率：8 MHz（基础频率）
- 常温频差：±10 ppm（典型室温校准误差）
- 频率稳定度（-20℃~+70℃）：±30 ppm
- 负载电容：20 pF（推荐设计值）
- 封装：HC-49S 直插封装，适配通孔 PCB
- 无源器件，低功耗，长期稳定性良好
三、电气与环境参数
- 工作温度范围：-20 ℃ 到 +70 ℃
- 工作模式：无源晶振，需外部振荡器电路驱动
- 频率精度指标以常温频差±10 ppm 与温度范围内的整体稳定度±30 ppm 为准，满足精密计时和通信等应用的中高精度要求。
四、使用与电路建议
- 负载电容选择：满足晶振标称 CL=20 pF。并联两侧电容 C1、C2 满足公式 CL ≈ (C1*C2)/(C1+C2) + Cstray。若 C1=C2，则 C1 ≈ 2×(CL − Cstray)。考虑 PCB 引线与器件寄生电容（Cstray 约 25 pF），建议 C1=C2 取 3036 pF 范围。
- 驱动电路：搭配晶体振荡器反相器（如 74HC04、专用晶体管驱动器或 MCU 内建振荡器），并根据驱动器 datasheet 调整负载与偏置。
- 布局注意：尽量缩短晶体与输入管脚间的走线，避免靠近高速信号或噪声源，减小寄生电容与干扰。
五、典型应用场景
- 单片机与嵌入式系统时钟源
- 工业控制、家电、消费电子定时与通信模块
- 仪表、测量设备与低速数据采集系统
六、装配与可靠性注意事项
- 直插 HC-49S 封装适用于手工焊接或波峰焊，焊接时避免长时间高温加热以防性能漂移。
- 存放与运输应防潮、防强电磁干扰，避免机械冲击；使用前按厂商推荐条件存储。
- ESD 敏感器件，装配和测试时注意静电防护。

Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
