X49SS2-25.000-F18LJDT 贴片晶振产品概述

一、产品基本信息

X49SS2-25.000-F18LJDT是杭晶电子(HCI) 推出的一款HC-49S-SMD封装贴片石英晶体谐振器,专为需要稳定时钟信号的电子设备设计。型号命名清晰映射核心参数:

  • “25.000”对应工作频率25MHz;
  • “F18”匹配负载电容18pF;
  • 后缀“L”关联工作温度范围-40℃~+85℃;
  • “JDT”为HCI内部品质等级标识,保障参数一致性。

作为贴片式晶振,该产品无需手工焊接,可通过SMT自动化贴装,适配高密度PCB布局,适合小型化、批量化生产场景。

二、核心性能参数详解

该晶振针对中高精度时钟需求优化,关键指标满足多领域应用:

1. 频率精度与稳定度

  • 常温频差:±20ppm(25℃环境下,频率偏差≤500Hz),可满足消费电子、通信设备的时钟同步要求;
  • 全温区频率稳定度:±30ppm(覆盖-40℃~+85℃),温度波动时频率漂移小,适合户外、工业现场等极端环境。

2. 负载与阻抗特性

  • 负载电容:18pF,需匹配电路端电容网络,保证晶振工作在谐振频率点,避免频率偏移;
  • 等效串联电阻(ESR):30Ω(中低水平),低ESR可减少功耗、降低电路噪声,延长产品使用寿命。

3. 环境适应性

工作温度范围-40℃~+85℃,覆盖工业级温度需求,可在南北极温差、工业车间高低温循环下稳定运行。

三、封装与典型应用场景

1. 封装特点

HC-49S-SMD为小型化贴片封装,尺寸约6.2×4.5×1.8mm,重量轻、抗干扰性强,适合:

  • 小型化设备(智能手表、无线耳机);
  • 高密度PCB设计(路由器、交换机)。

2. 典型应用

  • 通信设备:路由器、无线AP的时钟同步,保障数据传输准确性;
  • 工业控制:PLC、传感器节点的定时控制,适配工业现场温度波动;
  • 消费电子:智能手机、平板的音频处理、触控屏驱动;
  • 物联网设备:智能家居节点、穿戴设备的低功耗时钟;
  • 汽车电子:车载导航、行车记录仪的辅助时钟(非安全关键件)。

四、可靠性与品质保障

HCI针对该型号做了多项可靠性设计:

  • 机械可靠性:符合IEC 60068-2-6(振动)、IEC 60068-2-27(冲击)标准,可承受运输、安装中的机械应力;
  • 耐环境性:防潮、防腐蚀封装,符合RoHS 2.0无铅环保标准;
  • 长寿命:ESR控制在30Ω以下,内部损耗小,预期使用寿命≥10年(典型场景);
  • 出厂检测:每批次全参数检测,合格率≥99.9%。

五、品牌优势

杭晶电子(HCI)是国内石英晶振领域主流厂商,拥有20余年生产经验,产品覆盖消费电子、工业、汽车等领域。X49SS2-25.000-F18LJDT采用自主研发的高精度晶体切割工艺,可针对批量客户提供定制化参数(如更高稳定度、更低ESR)服务,售后支持完善。

该产品以稳定的性能、紧凑的封装和宽温适应性,成为中低端电子设备时钟信号的高性价比选择。

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.

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.

Replenishment inquiry Typical RFQ workflow
