TAXD25M2GLFBET2T 直插石英晶振产品概述

一、产品定位与核心身份

TAXD25M2GLFBET2T是雅晶鑫(YJX)推出的HC-49S封装直插石英晶体谐振器,属于通用型高频时钟基准器件。其核心功能是为电子设备提供稳定的25MHz正弦波时钟信号,适用于对精度、成本平衡要求较高的消费电子、工业控制、通信等领域,是替代传统温补/压控晶振的高性价比选择。

二、核心性能参数详解

该产品的关键参数围绕“稳定、高效、适配通用场景”设计,具体如下:

1. 基准频率与精度

  • 标称频率:25MHz(通信、消费电子领域主流通用频率,兼容多数MCU、射频芯片的时钟输入范围);
  • 常温频差:±30ppm(即25MHz×30×10⁻⁶=±750Hz),该精度可满足路由器、机顶盒等设备的时钟需求,无需额外校准;
  • 频率稳定度:±30ppm(涵盖工作温度范围-20℃~+70℃内的总偏差),结合常温频差,确保设备在不同环境温度下的时序稳定性。

2. 谐振特性与匹配

  • 负载电容:20pF(谐振器的最佳匹配负载),电路设计需保证外部负载电容(含PCB寄生电容)总和为20pF,以实现最优频率精度和起振性能;
  • 等效串联电阻(ESR):30Ω(低损耗设计),减少谐振时的能量损耗,提升信号幅度稳定性,降低电路起振难度,适合射频类应用。

三、封装形式与物理特性

TAXD25M2GLFBET2T采用HC-49S直插封装(DIP),具有以下特点:

  • 引脚间距符合行业标准(2.54mm),兼容传统通孔焊接工艺,便于PCB布局和批量组装;
  • 封装尺寸小巧(约11.5×4.5×3.8mm),节省设备内部空间;
  • 塑料封装防护性好,可抵抗轻度湿度、灰尘干扰,适合工业、车载等场景的长期使用。

四、典型应用场景

该产品的参数特性使其适配多种主流电子设备:

  1. 消费电子:路由器(主时钟驱动CPU/无线模块)、机顶盒(视频解码时序)、智能音箱(音频处理基准);
  2. 工业控制:PLC(传感器数据采集定时)、小型工业传感器(信号处理时钟);
  3. 通信设备:无线收发模块(2.4G/5G频段辅助时钟)、小型基站(本地时序参考);
  4. 车载电子:车载导航(-20℃~+70℃宽温适配)、辅助驾驶系统(辅助控制时序);
  5. 小型医疗设备:便携式监护仪(生理信号采集时钟)。

五、性能优势总结

  1. 成本与精度平衡:±30ppm的精度满足80%以上通用场景,无需温补/压控设计,降低系统BOM成本;
  2. 低损耗高可靠性:30Ω低ESR确保信号质量,HC-49S封装引脚焊接可靠性强,长期使用无接触不良风险;
  3. 宽温适配性:-20℃~+70℃工作范围,覆盖室内外、车载等多数应用环境;
  4. 品牌一致性:雅晶鑫(YJX)采用成熟石英晶体加工工艺,批量产品一致性好,供货稳定。

六、环境适应性与合规性

  • 工作温度:-20℃~+70℃(符合GB/T 14861-2019《石英晶体谐振器通用规范》);
  • 无铅环保:符合RoHS 2.0标准,满足出口及国内环保要求;
  • 长期可靠性:石英晶体固有老化率低(典型值<±5ppm/年),确保设备5年以上稳定运行。

综上,TAXD25M2GLFBET2T是一款“高性价比、通用适配、稳定可靠”的直插晶振,可作为多数电子设备的核心时钟基准,降低系统设计难度与成本。

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
