X49ST2-8.000-F18LJDTL 晶振产品概述
一、产品基本定位与核心优势
X49ST2-8.000-F18LJDTL是杭晶电子（HCI）推出的HC-49S封装直插式石英晶振，针对中低端电子设备的时钟信号需求设计，核心聚焦「高性价比+宽温适配+易焊接」三大特点。作为8MHz基准频率的晶体振荡器，它无需额外振荡电路即可输出稳定时钟，适合工业控制、通信、消费电子等多场景应用，是替代传统有源晶振的高成本效益选择。
二、关键性能参数详解
频率与频差控制
标称频率8MHz，常温频差±20ppm（25℃环境下，实际频率与标称值偏差≤160Hz），满足大多数设备对时钟精度的基本要求；频率稳定度±30ppm（工作温度范围内，频率变化≤240Hz），可适应-40℃至+85℃的宽温波动，避免极端温度下时钟漂移影响设备性能。负载与阻抗特性
负载电容18pF，需匹配外部18pF电容以优化振荡性能（若负载电容偏差过大，会导致频率偏移或振荡不稳定）；等效串联电阻（ESR）60Ω，较低的ESR可减少功率损耗，提升信号信噪比，延长设备使用寿命。环境适应性参数
工作温度范围**-40℃+85℃**，覆盖工业级环境的典型温度波动（如户外设备、车间控制器）；存储温度一般为-55℃+125℃（杭晶标准），满足运输与长期存储需求。
三、封装与物理特性
采用HC-49S直插式封装，具体物理参数（杭晶标准）：
- 尺寸：11.5mm（长）×4.5mm（宽）×3.8mm（高），体积小巧，可适配紧凑PCB布局；
- 引脚：2引脚直插式，间距2.54mm（标准DIP间距），焊接兼容性强（手工焊、波峰焊均可）；
- 封装材料：陶瓷外壳，耐高温、抗冲击，可有效隔离外部电磁干扰，保护内部石英晶体谐振器。
四、典型应用场景
结合参数特性，X49ST2-8.000-F18LJDTL适用于以下场景：
- 工业控制设备：PLC可编程控制器、变频器、传感器模块（宽温适配车间/户外环境）；
- 通信终端：路由器、交换机、无线AP（8MHz是常用时钟频率，频差满足数据传输稳定性）；
- 消费电子：机顶盒、智能电视、车载多媒体（ESR低，功耗控制好，适合批量生产）；
- 仪器仪表：示波器、万用表、信号发生器（频率稳定度满足测量精度要求）。
五、可靠性与应用注意事项
- 可靠性验证：杭晶晶振符合GB/T 15295-2013等国内标准，以及MIL-STD-202部分测试要求（振动、冲击、湿度测试），可稳定工作10万小时以上；
- 应用注意：需严格匹配18pF负载电容（避免使用16pF/20pF等非标称电容）；焊接温度不宜超过260℃（防止引脚镀锡氧化）；避免靠近强电磁干扰源（如高频变压器），防止时钟信号失真。
该产品以高性价比和宽温适配性，成为中低端电子设备时钟模块的主流选择，可满足多数工业、通信、消费类场景的基础时钟需求。

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.
