X49SD5MSD2SC 产品概述
一. 概述
X49SD5MSD2SC 是 YXC（扬兴科技）出品的直插式石英晶体谐振器，封装为 HC-49S（直插/插脚型）。标称振荡频率为 5.000 MHz，面向需稳定时钟源的通用电子设备，兼具体积小、频率稳定、易于装配等优点，适合传统插件工艺的产品线。
二. 主要参数
- 标称频率：5 MHz
- 常温频差（初始容差）：±20 ppm
- 频率稳定度（温度范围内）：±30 ppm
- 工作温度：-20 ℃ ～ +70 ℃
- 负载电容：20 pF
- 封装形式：HC-49S（直插晶振）
- 类型：晶体 / 晶振（用于微控制器、时钟回路等）
三. 主要特性
- 稳定性好：常温初始频差 ±20 ppm，满温区稳定度 ±30 ppm，能满足中高精度时钟需求。
- 插脚封装：HC-49S 封装便于手工或波峰焊装配，适配传统插件工艺。
- 通用负载：20 pF 负载电容与多数微控制器及振荡电路兼容，便于系统整定。
- 宽温区适用：-20 ℃ 至 +70 ℃ 覆盖常见消费与工业级环境。
四. 应用场景
适用于嵌入式控制器时钟、消费电子、通讯模块、测量仪器、工业控制板及其他需稳定频率的振荡电路。尤其适合仍采用直插式元件布局或要求便于现场更换的场合。
五. 选型与使用建议
- 在设计时确认电路的实际负载电容与晶体标称 20 pF 匹配，必要时通过调整并联电容微调频率。
- 装配时应避免对封装体和引脚施加过大机械应力，弯折引脚应保留足够距离以减小应力传递。
- 焊接工艺请参照厂家推荐的加热曲线，避免长时间高温直接作用于晶体体部；若无明确资料，建议采用短时、适度温度的焊接方式并作返修限制。
- 对于需更高温区或更严格频率稳定性的场合，应选用更高等级零件或采用温补/恒温晶体方案。
六. 可靠性与检验
出厂通常经过频率、谐振阻抗和外观检查，建议入库后在常温下进行抽样频率检验以确认常温频差。储存与使用时注意防潮、防静电并避免剧烈振动与冲击，以保证长期频率稳定性。
七. 订购与服务
订货型号：X49SD5MSD2SC（品牌：YXC 扬兴科技；封装：HC-49S；频率：5 MHz；负载电容 20 pF；常温频差 ±20 ppm；温度稳定度 ±30 ppm）。订购时请注明所需频率、公差与包装方式（如条带/散装）并与供应商确认交付时间与检验要求。若需更高精度或特殊温度范围，请联系厂家提供定制化方案。

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.
