X49SD12MSD2SI 产品概述
一、产品简介
X49SD12MSD2SI 是 YXC（扬兴科技）出品的一款无源直插晶振，工作频率为 12.000 MHz，采用传统 HC-49S 金属罐直插封装。该器件为无源晶体谐振器，需要配合外部振荡电路（如微控制器内部振荡器或专用晶振振荡器）使用，广泛适用于对稳频有要求的通用电子设备和工业控制系统。
二、主要参数
- 类型：无源晶振（直插/HC-49S）
- 频率：12.000 MHz
- 常温频差（初始频差）：±20 ppm
- 工作温度范围：-40 ℃ ～ +85 ℃
- 频率稳定度（含温度影响）：±30 ppm
- 负载电容：20 pF
- 封装：HC-49S（直插）
三、产品特点
- 稳定性高：常温初始频差±20 ppm，温度工作范围内频率稳定度可控在±30 ppm，满足多数精密定时与频率参考需求。
- 可靠性好：HC-49S 金属封装对机械振动和湿度有较好防护，适合长期工作环境。
- 易于安装：直插式引脚便于通孔焊接和手工/波峰焊加工，适配传统装配工艺。
- 兼容性强：无源设计可与各种振荡器电路配合，便于系统级调试与优化。
四、典型应用
- 单片机/微控制器的系统时钟源
- 串行通信、调制解调器与基带电路时钟
- 时钟同步、计时与测量仪器
- 工业控制、仪表与消费电子等需要中等精度频率参考的场景
五、封装与机械适配
X49SD12MSD2SI 采用标准 HC-49S 金属罐直插封装，适配通孔 PCB 布局与常规插装工艺。为保证最佳性能，建议在 PCB 设计时合理布局振荡器周边元件，尽可能缩短晶体到振荡器引脚之间的走线，避免与高频、高噪声信号线并行布线。
六、使用与注意事项
- 本器件为无源晶振，必须配合振荡器电路（如反相器或 MCU 内部振荡器）及两只负载电容（典型值与器件负载电容匹配，参考 20 pF）使用。
- 在布局时应将负载电容接地尽量靠近振荡器输入脚，以减少寄生电容与干扰。
- 避免对金属罐施加机械应力或强烈冲击，防止影响谐振频率或损伤晶体。
- 焊接时注意避免长时间高温暴露，遵循厂商的焊接工艺建议以保证可靠性与频率稳定性。
- 推荐在产品开发阶段进行充分的温漂及相位噪声验证，以确定最终电路参数与匹配元件值。

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.
