TAXD7.3728M2GLDBET2S 直插石英晶振产品概述

一、产品基本信息

TAXD7.3728M2GLDBET2S是雅晶鑫(YJX)推出的HC-49S封装直插石英晶体谐振器,属于通用型频率基准器件。该产品以7.3728MHz稳定输出为核心,适配多种电子设备的时钟同步、波特率生成等需求,具备成本可控、可靠性高的特点,广泛应用于消费类电子、工业控制、微控制器系统等领域。

二、核心电气参数详解

产品关键参数决定了适用场景与性能表现,具体如下:

  1. 基准频率:7.3728MHz
    该频率是串口通信(UART)的经典适配频率,可通过简单分频直接生成1200bps、9600bps、19200bps等标准波特率,无需额外校准电路,简化设计流程。
  2. 常温频差:±20ppm
    指25℃常温下的频率偏差(换算为Hz约±147Hz),满足多数通用应用对频率精度的要求(如普通MCU时钟、简易仪表显示)。
  3. 负载电容:20pF
    晶振工作需外接匹配电容(通常2个10pF并联),保证振荡稳定起振与频率准确,HC-49S封装默认推荐该值。
  4. 频率稳定度:±30ppm
    包含温度变化、电源波动等综合偏差,覆盖-20℃~+70℃工作范围,确保不同环境下频率一致性。
  5. 等效串联电阻(ESR):80Ω
    属于HC-49S封装的典型合理范围,既保证振荡幅度足够(驱动电路易起振),又避免电阻过大导致的功耗增加或稳定性下降。

三、封装与物理特性

  • 封装类型:HC-49S(直插式DIP)
  • 引脚数量:2引脚(石英晶振标准配置)
  • 尺寸规格:符合行业标准(长≈11mm,宽≈4.5mm,高≈3.5mm,引脚间距2.54mm),适配常规PCB插件设计,手工焊接与自动化生产均兼容。
  • 外壳材质:金属屏蔽外壳,有效隔离外界电磁干扰(EMI),保护内部石英晶片免受机械损伤与环境影响,提升频率稳定性。

四、典型应用场景

结合参数与封装特性,该产品适用于:

  1. 微控制器(MCU)时钟源:如STC89系列、ATmega328P等8位MCU的外部晶振,替代内部RC振荡器,提升时钟精度。
  2. 串口通信模块:蓝牙、WiFi模块的UART接口时钟,保证波特率准确,减少数据误码率。
  3. 消费类电子:小家电控制板(电饭煲、电磁炉)、遥控器、电子钟的频率基准,满足低成本高可靠需求。
  4. 工业控制模块:PLC辅助时钟、传感器采集电路的频率源,适配-20℃~+70℃工作温度。

五、性能优势总结

  1. 频率适配性强:7.3728MHz精准匹配串口波特率,无需额外校准,降低设计成本。
  2. 稳定性可靠:±20ppm常温频差、±30ppm温度稳定度,覆盖多数应用精度需求。
  3. 封装兼容性好:HC-49S直插封装为行业标准,替换方便,适配新旧设备升级。
  4. 抗干扰性优异:金属外壳屏蔽电磁干扰,适合复杂电磁环境。
  5. 成本效益高:通用型晶振性价比突出,适合批量生产应用。

六、环境适应性说明

  • 工作温度:-20℃~+70℃,覆盖家庭、办公室、普通工业现场温度变化。
  • 储存温度:参考行业标准(-40℃~+85℃),保证运输存储可靠性。
  • 湿度适应性:10%~90%RH(无凝露),满足多数场景湿度要求。

该产品通过稳定的频率输出与可靠的环境适应性,成为通用电子设备频率基准的优选方案。

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
