X49ST2-12.000-F20JGDT 产品概述
一、产品概述
X49ST2-12.000-F20JGDT 为全国产化直插晶体元件，型号封装为 HC-49S-2P（直插式 HC-49S 直立封装）。标称振荡频率 12.000 MHz，常温频差 ±30 ppm，长期频率稳定度 ±50 ppm，等效串联电阻（ESR）约 50 Ω，推荐负载电容 20 pF，工作温度范围 -40 ℃ ～ +85 ℃。品牌：HCI（杭晶）。该器件适用于需要高稳定性、低成本的通用振荡源场合。
二、主要特性
- 频率：12.000 MHz，常温频差 ±30 ppm，频率长期稳定 ±50 ppm。
- 负载电容：20 pF，适配常见晶体振荡电路（请按电路实际寄生电容和 PCB 布局调整）。
- 等效串联电阻（ESR）：约 50 Ω，便于在中低负载驱动条件下实现稳定启动。
- 工作温度：-40 ℃ ～ +85 ℃，适合工业级应用环境。
- 封装：HC-49S-2P 直插（2 引脚），便于手工焊接和传统波峰/混合装配工艺。
- 全国产化，供应链可控，适合国产化替代与量产需求。
三、典型应用
- MCU 时钟源、微控制器与单片机系统
- 通信设备、无线模块本振参考
- 工业控制、仪器仪表时基
- 消费类电子、数字电路与测量系统的参考频率
四、封装与安装建议
HC-49S-2P 为传统直插封装，安装时注意：引脚弯折应在离封装体适当距离进行，避免应力传递到封装体；焊接时建议采用常规手工或波峰焊工艺，控制焊接温度与时间以免长期高温影响频率稳定性；在电路板布线时，晶体附近走线应避免大电流回路，减少干扰并尽量靠近振荡器输入端放置负载电容与反馈元件，以获得最佳启动与相位噪声性能。
五、可靠性与测试建议
出厂通常经过筛选与老化测试以保证标称频差与稳定度。用户在设计验证阶段应进行：
- 实温度循环测试确认在目标温区内的频率漂移；
- 加载匹配测试，验证在所选电路负载电容下的振荡启动与稳态性能；
- 老化观察以评估长期频率漂移。
六、采购与替代注意
选型时请核对频差、负载电容与工作温度要求，若电路对启动时间或相位噪声有更高要求，可与厂方沟通更严格规格或筛选等级。HC-49S-2P 直插封装便于替换与调试，适合样机验证与小批量生产。
如需更详细的电气等效电路参数、老化曲线或订购信息，建议联系 HCI（杭晶）或其授权分销商获取完整数据手册与测试报告。

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.
