TAXD26M2GJDAET2S 产品概述

一、产品简介

TAXD26M2GJDAET2S 是雅晶鑫(YJX)出品的一款直插式晶体谐振器,封装为传统 HC-49S(49S)直插型。标称工作频率 26.000 MHz,适用于需要稳定基准时钟的各类电子设备和通信终端,兼顾可靠性与通用性,适合波峰焊/插件工艺的混合装配环境。

二、主要参数

  • 频率:26 MHz
  • 常温频差(室温标称):±20 ppm
  • 频率稳定度(全温带):±30 ppm
  • 负载电容:16 pF
  • 等效串联电阻(ESR):30 Ω
  • 工作温度范围:−10 ℃ ~ +60 ℃
  • 封装:HC-49S(直插)
  • 品牌:YJX(雅晶鑫)
  • 描述标签:49S,26MHz,16pF,+/-20ppm,-10℃~+60℃,30Ω

三、特性与优势

  • 稳定度高:常温±20 ppm、全温带±30 ppm 能满足多数微处理器和通信设备对时钟精度的要求。
  • 适配性强:16 pF 负载电容为常见值,便于与多数晶振电路(特别是管脚型晶振或集成振荡器)匹配。
  • 机械可靠:HC-49S 金属/玻璃封装对机械冲击和环境振动具有良好耐受性,适合通过孔安装与现场维修。
  • 可维护性好:直插式设计便于手工替换和调试,适用于样机验证及小批量生产。

四、典型应用场景

  • 嵌入式系统主时钟与外设时钟源
  • 通信设备与网络终端的参考频率
  • 测试与测量仪器、示波器、频率合成模块
  • 工业控制、安防设备、消费电子中的时钟发生器

五、封装与电气配合建议

  • 建议电路中两侧并联电容按经验值计算:若目标负载电容为 CL=16 pF,考虑 PCB 与输入管脚的寄生电容(约 2–5 pF),每侧并联电容可选在 22–33 pF 范围,最终值以实际电路和启动时间为准。
  • ESR 为 30 Ω,说明驱动级必须能提供足够增益以保证启动。用于驱动能力较弱的振荡器输入时,应评估启动时间与稳定性。
  • 放置位置尽量靠近 MCU/振荡器输入端,减少走线和寄生电容变化,避免强干扰源(开关电源、射频发射器)邻近。

六、选型与使用注意

  • 工作温度仅覆盖 −10 ~ +60 ℃,用于工业或严格温度环境时需谨慎选择更宽温带产品。
  • 若系统对长期频率漂移或温度漂移有更高要求,应选用温补或更高稳定度等级产品。
  • 在高振动或冲击环境下,建议进行机械可靠性验证或选择防振动等级更高的封装。

七、质量与可靠性

雅晶鑫(YJX)为该系列提供标准出厂测试与筛选,HC-49S 结构成熟、生产工艺稳定。在生产与采购时建议索取检验报告(频率分布、老化测试、ESR 测试等)以便于批次一致性管理。

总结:TAXD26M2GJDAET2S(49S,26MHz,16pF,±20ppm/±30ppm,ESR 30Ω,−10~+60℃)是一款面向通用电子与通信应用的可靠直插晶振,适合需要易维护、稳定时钟源的场合。选择和应用时请关注负载匹配、驱动能力与工作温度范围,以保证系统性能。

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
