X49SD4MSD2SC 产品概述
一、产品简介
X49SD4MSD2SC 是来自 YXC 扬兴科技的一款无源直插晶体振荡器（直插晶振），标准 HC-49S 封装，标称频率 4.000 MHz。器件为被动晶体，用于为振荡器电路、微控制器和各种时钟源提供稳定频率基准，适合传统直插安装和试验开发场景。
二、主要性能参数
- 晶振类型：无源晶振（直插）
- 频率：4 MHz
- 常温频差（初始容差）：±20 ppm（25℃）
- 频率稳定度（工作温度范围内）：±30 ppm
- 负载电容：20 pF
- 工作温度：-20 ℃ ~ +70 ℃
- 封装形式：HC-49S（直插/Through-hole）
- 品牌：YXC 扬兴科技
- 型号：X49SD4MSD2SC
三、产品特点
- 稳定性好：常温初始频差±20 ppm，满足对频率精度有较高要求的应用。
- 温度适应范围适中：在-20℃~+70℃范围内频率稳定度控制在±30 ppm，适用于商用与工业级常温环境。
- 标准直插封装：HC-49S 直插封装便于手工焊接、板级替换与原型调试。
- 负载电容匹配：20 pF 负载电容，适配常见微控制器与分立振荡电路设计。
四、典型应用
- 单片机与嵌入式系统的主时钟源
- 工业控制、仪器仪表的时间基准
- 通信设备、测量设备和消费电子（需直插封装）
- 实验开发板、样机验证及维修替换件
五、使用与安装建议
- 负载电容匹配：在振荡器电路中按晶振标称负载电容（20 pF）选择外部电容，以保证频率精度。
- 布线与接地：尽量缩短晶体到振荡器输入端的引线长度，避免大面积耦合和噪声耦合，地线要可靠。
- 驱动电平与老化：遵循振荡器电路设计规范，避免过高驱动电平引起频率漂移或老化。
- 焊接工艺：建议采用温和焊接条件，避免长期高温烙铁直触引脚以减少热应力。直插产品在焊接后可适当修整引脚长度。
六、注意事项与保管
- 贮存环境应干燥、避免强腐蚀性气体及剧烈振动。
- 避免强烈机械冲击与弯折引脚，晶体频率可能因应力改变。
- 建议按批次记录出厂频差与检验数据，便于后续品质追溯与替换匹配。

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.
