X49ST2-8.000-F20JGDT 石英晶体振荡器产品概述
一、产品基本信息
X49ST2-8.000-F20JGDT是杭晶电子（HCI） 推出的工业级直插石英晶体谐振器（无源晶振），采用经典HC-49S封装。型号命名中，“8.000”对应标称频率8MHz，“F20”明确负载电容20pF，“JGDT”为杭晶针对宽温应用的定制标识，整体定位为中高频、高稳定性的通用时钟参考源。
二、核心性能参数解析
该晶振的关键参数完全满足工业级应用需求，具体如下：
- 标称频率：8MHz，为工业控制、通信设备等领域的主流时钟频率，兼容性强；
- 常温频差：±30ppm，即常温（25℃）下实际频率与8MHz偏差≤±240Hz，满足多数数字电路的时序精度要求；
- 负载电容：20pF，需匹配电路中20pF电容以实现最佳谐振，避免频率偏移；
- 频率稳定度：±50ppm，指工作温度范围内频率变化≤±400Hz，确保极端环境下时钟稳定性；
- 等效串联电阻（ESR）：60Ω，低于同类型晶振典型值（≤100Ω），可降低电路功耗、提升谐振效率；
- 工作温度范围：-40℃~+85℃，覆盖工业级环境的高低温波动，适配户外设备、车载系统等场景。
三、封装与可靠性设计
采用HC-49S直插封装，具备以下可靠性优势：
- 结构抗扰：金属外壳+陶瓷基座设计，抗振动（10g~20g）、耐冲击（1000g），可应对工业现场机械应力；
- 安装便捷：2引脚直插式，适配传统PCB通孔焊接，降低生产难度；
- 防护性强：密封封装隔绝灰尘、湿度，MTBF（平均无故障时间）达10^6小时以上，长期可靠性高。
四、典型应用场景
凭借宽温、高稳定、低ESR特点，该晶振广泛应用于：
- 工业控制：PLC、变频器、伺服驱动器的时钟参考，保证控制信号时序精度；
- 通信终端：微基站、路由器、交换机的本地时钟源，满足数据传输同步需求；
- 消费电子：机顶盒、智能网关、安防摄像头的系统时钟，提升设备运行稳定性；
- 仪器仪表：示波器、信号发生器的基准时钟，保证测量精度；
- 车载辅助：车载显示屏、倒车雷达控制器的时钟，适应车内温波动。
五、产品优势总结
相比同类型晶振，该产品核心优势突出：
- 宽温适配：-40℃+85℃覆盖工业级环境，超出商用级（0℃70℃）温度范围；
- 性能均衡：低ESR（60Ω）+ 高稳定度（±50ppm），功耗与精度平衡最优；
- 品牌保障：杭晶电子为国内晶振老牌厂商，工艺成熟、质量管控严格，产品一致性好。
综上，X49ST2-8.000-F20JGDT是高性价比工业级直插晶振，适合对温度、稳定性有较高要求的中高频时钟参考场景。

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.
