049ST2-8.000F16HPNLL 直插石英晶振产品概述

一、产品基本定位与典型应用

049ST2-8.000F16HPNLL是杭晶(HCI)推出的HC-49S封装直插石英晶振,核心频率8MHz,属于中精度通用型晶振,主要适配对成本敏感、精度要求适中的电子设备:

  • 工业端:PLC可编程逻辑控制器、小型变频器、传感器数据采集模块的时钟同步(需稳定频率保证控制逻辑一致性);
  • 消费端:智能家电(洗衣机、空调控制板)、小型路由器的信号处理时钟(满足日常使用的频率稳定性);
  • 通信端:低速率无线模块(蓝牙2.0、ZigBee早期设备)的载波频率参考(适配低速数据传输的精度需求)。
    该晶振以成熟工艺和高性价比,覆盖了大多数民用与轻度工业场景的时钟需求。

二、核心技术参数详解

这款晶振的参数针对通用场景做了针对性优化,关键指标如下:

  1. 频率特性:标称频率8MHz,常温(25℃)频差±10ppm(即频率偏差≤80Hz),满足数字电路的基本时钟精度;工作温度范围(-20℃~+70℃)内频率稳定度±20ppm,可应对轻度温变(如室内环境的昼夜温差),避免频率漂移影响设备性能。
  2. 负载匹配:负载电容16pF(石英晶振的常用匹配值),电路设计中只需并联16pF电容(需考虑PCB寄生电容)即可实现稳定振荡,降低了硬件匹配的设计难度。
  3. 起振可靠性:等效串联电阻(ESR)60Ω,处于石英晶振的合理起振范围(一般<100Ω即可可靠起振),保证电路上电后快速起振,且在温度变化时仍能维持振荡稳定性。
  4. 环境适应性:工作温度-20℃~+70℃,覆盖大部分室内设备及常温户外场景(如小型监控摄像头),无需额外宽温设计即可满足需求。

三、封装与工艺特性

采用HC-49S金属封装(直插晶振经典形式),具备以下优势:

  • 物理尺寸:标准HC-49S尺寸(长≈11mm×宽≈4.5mm×高≈3.5mm),引脚间距符合通用PCB规范,方便焊接与布局;
  • 电磁屏蔽:金属外壳可有效隔离外界电磁干扰(EMI),适合工业现场等电磁环境复杂的场景(如电机附近的控制板);
  • 气密性:激光焊接封装工艺,气密性良好,可防止湿度、灰尘进入,延长晶振使用寿命(典型寿命≥5年);
  • 杭晶工艺:HCI作为国内老牌晶振厂商,该型号采用高精度石英晶体切片与镀电极工艺,保证批量生产的频率一致性(同批次频差可控制在±5ppm内)。

四、应用注意事项

为保证晶振性能稳定,设计与使用需注意以下要点:

  1. 负载电容匹配:电路总负载电容需严格控制在16pF(包括晶振引脚寄生电容、PCB走线电容),若匹配不当会导致频率偏差增大或无法起振;
  2. 焊接规范:直插引脚焊接温度建议≤260℃(单引脚焊接时间≤3秒),避免高温损坏晶振内部石英片;
  3. 抗振防护:晶振对机械振动敏感,安装时需远离电机、风扇等振动源,必要时可加橡胶垫减震;
  4. 存储条件:未焊接的晶振需存储在常温(15℃~35℃)、干燥(湿度≤60%)环境中,避免阳光直射与剧烈碰撞。

五、总结

049ST2-8.000F16HPNLL作为HCI的中精度HC-49S直插晶振,以8MHz核心频率、±10ppm常温频差、16pF负载电容为核心优势,适配工业控制、消费电子等通用场景。其金属封装的屏蔽性与杭晶的成熟工艺,保证了可靠性与性价比,是替代进口同类型晶振的高性价比选择。

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.
