X49SD6MSD2SC 产品概述

一、产品简介

X49SD6MSD2SC 为 YXC(扬兴科技)出品的无源直插晶振,封装为常见的 HC-49S 直插式外形,标称频率 6.000MHz。该器件在常温下初始频差 ±20ppm,建议配合负载电容 20pF 使用,频率稳定度(含温度影响)为 ±30ppm,工作温度范围为 -20℃ ~ +70℃。作为无源晶体,需与外部振荡电路(如常用的 Pierce 振荡电路)配合使用。

二、主要技术参数

  • 型号:X49SD6MSD2SC
  • 类型:无源晶体(直插)
  • 工作频率:6.000 MHz
  • 常温频差(Initial tolerance):±20 ppm
  • 负载电容(Cl):20 pF
  • 频率稳定度(含温度):±30 ppm(-20℃ ~ +70℃)
  • 工作温度:-20℃ ~ +70℃
  • 封装:HC-49S(直插)
  • 品牌:YXC 扬兴科技

注:有关等效串联电阻(ESR)、驱动电平、老化特性等详细电参数,请参见厂方规格书或向供应商确认。

三、主要特点

  • 高精度:常温频差±20ppm,适合对时基精度有较高要求的应用。
  • 适用性强:20pF 负载电容常见于多数 MCU/外围振荡电路,便于电路匹配。
  • 通用封装:HC-49S 直插封装,适合通孔焊接、手工装配与快速替换。
  • 宽温区间:-20℃~+70℃ 满足一般消费类与部分工业类环境要求。
  • 无源设计:便于与各类晶体振荡器电路搭配,灵活性高。

四、典型应用场景

  • 单片机/微处理器时钟源(嵌入式控制板)
  • 通信设备与数传模块的本振参考
  • 仪器仪表与测量系统的频率基准
  • 消费电子与家用电器的控制时钟
  • 教学与开发板的通用时钟参考

五、使用与电路匹配建议

  • 外部电容匹配:在常见 Pierce 振荡器中,负载电容 Cl 与两端电容 C1、C2 的关系为 Cl = (C1·C2)/(C1 + C2) + Cstray。若取 C1 = C2 = C,则近似 C ≈ 2·(Cl - Cstray)。以 Cl = 20pF、印制板及管脚寄生电容 Cstray 约 2–5pF 为例,每端电容可选 ≈30–36pF,具体值建议在样机调测时微调以获得最佳频率与启动特性。
  • 驱动电平与老化:请按照目标振荡器芯片推荐的驱动电平工作,避免过高驱动导致晶体非线性或加速老化。
  • 焊接工艺:HC-49S 为直插元件,推荐遵循通用波峰/手工焊接温度曲线,避免长时间高温作用于晶体体。具体焊接温度与时间请参照厂方工艺建议或 IPC 标准。
  • 环境验证:在有严格温度或振动要求的应用,请做热循环与振动可靠性验证,并关注器件老化漂移。

六、选型与测试要点

  • 在最终设计前,获取完整数据手册,确认 ESR、驱动功率、老化速率等参数是否满足系统需求。
  • 样板调试阶段测量实际频差、起振时间、相位噪声(如有需求)与老化趋势。
  • 对于要求更宽温度或更高稳定度的场合,可考虑工业级或温补(TCXO)/恒温(OCXO)方案替代。

七、结论

X49SD6MSD2SC(YXC 扬兴科技,HC-49S,6MHz,20pF,±20ppm/±30ppm,-20℃~+70℃)适用于需要稳定 6MHz 时钟源且便于通孔安装的通用电子产品与开发应用。在实际应用中应注意负载电容匹配、驱动电平控制与焊接工艺,并在样机阶段完成频率与可靠性验证,以确保长期稳定运行。若需更详细电气特性或可靠性试验数据,请联系供应商获取完整规格书。

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
