X49SM5MSD2SC 产品概述

一、产品概述

X49SM5MSD2SC 是 YXC(扬兴科技)推出的一款贴片晶体谐振器,标称频率为 5.000 MHz。该器件采用 HC-49S-SMD 封装,面向需要稳定时钟源的消费电子、通信设备、微控制器与测量仪器等应用场景。器件在常温下频差(初始容差)为 ±20 ppm,温度范围内频率稳定度可达 ±30 ppm,典型负载电容为 20 pF。

二、主要特性

  • 频率:5.000 MHz(标称)
  • 初始频差(常温):±20 ppm
  • 温度稳定度:±30 ppm(工作温度范围内)
  • 工作温度:-20 ℃ ~ +70 ℃
  • 负载电容:20 pF
  • 封装形式:HC-49S-SMD(贴片晶振)
  • 品牌:YXC 扬兴科技

三、应用场景

  • 单片机与微处理器时钟源
  • 实时时钟模块(RTC)与计时类设备
  • 通信与网络设备的参考时钟
  • 工业与消费类电子产品的定时与同步电路
  • 各类测量、测试及控制系统

四、封装与安装建议

X49SM5MSD2SC 采用 HC-49S-SMD 贴片封装,适用于自动贴装与回流焊工艺。为保证最佳频率性能,建议在 PCB 设计时:

  • 为晶体提供靠近振荡芯片的布局,缩短走线,减少寄生电容与噪声耦合;
  • 使用对称走线并做好接地处理,避免信号干扰;
  • 参考实测负载电容值调整外围电容,以匹配 20 pF 的额定负载;
  • 遵循厂商推荐的回流焊温度曲线与湿敏等级要求,避免过热导致性能退化。

五、使用与注意事项

  • 在设计振荡电路时,应匹配合适的放大器/反相器及反馈网络,防止起振困难或谐振点偏移;
  • 避免长时间在极端温度或高湿环境中工作,超出规定温度会影响频率与寿命;
  • 注意防静电与机械冲击,搬运与贴装时使用防护措施;
  • 对关键时间基准应用,建议在系统级进行频率校准与温漂补偿。

六、采购与质量保证

YXC 扬兴科技为该型号提供批量生产与质量管控,出货通常附带频率检验报告与出厂测试数据。采购时请确认型号 X49SM5MSD2SC、封装 HC-49S-SMD 与所需频差等级,必要时索取样品进行电路兼容性验证。若用于关键或高可靠性场合,可与厂商沟通更严格的筛选或定制规格。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
