X49SS2-8.000-F20JJHP贴片晶振产品概述
一、产品核心定位
X49SS2-8.000-F20JJHP是杭晶电子（HCI）推出的HC-49S-SMD封装贴片石英晶振，以8MHz为基础频率，针对常规工业控制、消费电子及小型通信设备的时钟信号需求设计，兼顾稳定性与成本优势，适配自动化贴装产线，是替代传统直插晶振的高性价比选择。
二、关键性能参数解析
（一）频率与精度指标
- 基础频率：8.000MHz，属于电子设备中常用的中低频时钟基准，广泛适配单片机（如ATmega系列、STM32入门级）、蓝牙低功耗（BLE）模块等；
- 常温频差：±30ppm（百万分之三十），换算为频率偏移约±240Hz，可满足多数场景对时钟精度的要求（例如：蓝牙模块要求频差≤±50ppm，单片机时序要求通常≤±50ppm）；
- 频率稳定度：±30ppm（覆盖工作温度范围），即温度从-20℃变化至+70℃时，频率偏移仍控制在±30ppm内，避免温变导致的时序误差。
（二）电路匹配参数
- 负载电容：20pF，需在电路设计中匹配等效负载电容为20pF（包括晶振引脚寄生电容），确保晶振工作在谐振状态；
- 等效串联电阻（ESR）：60Ω，属于HC-49S-SMD封装8MHz晶振的常规合理范围，低ESR可减少信号损耗，保证振荡电路的启动可靠性与稳定性。
三、封装与物理特性
X49SS2-8.000-F20JJHP采用HC-49S-SMD贴片封装，对比传统直插HC-49S封装，具备以下优势：
- 适配SMT自动化贴装，提升生产效率，降低人工成本；
- 节省PCB空间，符合现代电子设备小型化、轻薄化趋势；
- 引脚设计简洁，减少焊接缺陷风险，提升产品一致性。
四、典型应用场景
结合参数与封装特性，该晶振适用于以下场景：
- 工业控制单元：PLC（可编程逻辑控制器）子模块、传感器数据采集卡的时钟基准，工作温度范围匹配室内工业环境；
- 消费电子设备：智能家居网关、智能插座、小型蓝牙音箱的BLE模块时钟源；
- 单片机系统：8位/32位MCU的外部时钟（替代内部RC振荡器，提升时序精度）；
- 小型仪表：温湿度传感器、计数器、小型电子钟的定时基准。
五、品质与可靠性保障
杭晶电子（HCI）作为国内石英晶振领域的成熟供应商，该产品具备以下品质保障：
- 环保合规：采用无铅工艺，符合RoHS 2.0标准，适配全球电子市场准入要求；
- 温区覆盖：工作温度范围-20℃~+70℃，满足大部分常规应用场景（非极端低温/高温环境）；
- 一致性稳定：批量生产中参数波动小，ESR、频差等指标符合规格书要求，降低终端产品故障风险。
该产品通过了基础可靠性测试（如振动、冲击测试），可满足多数中低端电子设备的长期稳定运行需求，是性价比突出的常规时钟基准器件。

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.
