X49SD25MSD2SI 是 YXC(扬兴科技)生产的一款无源直插式晶振,基准频率为 25.000 MHz,采用经典 HC-49S 直插封装。该器件为基础频率(fundamental)工作模式的无源晶体,适用于需要高稳定频率参考的数码通信、微控制器时钟、射频前端参考以及各种测试测量设备。器件以良好的频率稳定性和传统封装的机械可靠性著称,便于手工装配与波峰/浸锡焊接工艺。
注:上述频差与稳定度为典型出厂标准,具体批次详细出厂检验数据请参考合格证或向供应商索取检验报告。
X49SD25MSD2SI 采用工业常见的 HC-49S 直插封装,体积小,机械强度高,适合手工装配和通过传统波峰或选择性焊接方式安装。直插脚便于穿板固定,适用于需要较强机械支撑或后期手工更换的场合。封装标识上通常印有型号与频率信息,出厂时会有包装盘或复合防潮包装以保证运输与存储稳定性。
注意:作为无源晶体,X49SD25MSD2SI 必须配合外部晶振电路(如常见的 Pierce 振荡器或专用晶体振荡器 IC)使用。
X49SD25MSD2SI 设计工作温度为 -40 ℃ 到 +85 ℃,满足工业级温度范围要求。出厂经过基本振动、冲击和温度测试以保证机械与频率稳定性。对于长期稳定性(老化)和在极端温度下的频率漂移,请参考出厂的检验报告或向供应商咨询进一步的可靠性数据。
在订购时请确认型号、频率、负载电容与稳定度等关键参数,并向供应商索取出厂检验报告与包装样式。YXC 扬兴科技提供标准出货批次与可追溯的质检记录,适合量产与工程样机验证。
如需更详细的电气测试数据、老化曲线或针对特定振荡器的匹配建议,可提供电路原理图与应用场景,我可进一步给出优化与调试建议。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
