TAXD12M2GLDBET8S无源晶振产品概述

TAXD12M2GLDBET8S是雅晶鑫(YJX)推出的一款HC-49S封装直插无源石英晶体谐振器,专为需要稳定12MHz时钟信号的电子设备设计,具备精度适中、可靠性高、安装便捷等特点,广泛适配各类嵌入式系统、工业控制及消费电子领域。

一、产品基本信息

该型号为无源晶振(需外接振荡电路实现信号输出),品牌为国内晶振领域知名厂商雅晶鑫(YJX),封装采用成熟的HC-49S直插式,引脚数量为4(其中2个为有效振荡引脚,2个辅助固定),整体尺寸紧凑,适合传统插件工艺的电路设计。

二、核心电气性能参数

TAXD12M2GLDBET8S的关键电气参数可满足多数通用场景的时钟需求:

  • 标称频率:12MHz(行业通用标准频率,适配多数MCU、单片机的时钟输入);
  • 常温频差:±20ppm(即12MHz下频偏为±240Hz,精度满足日常电子设备的基本时钟要求);
  • 负载电容:20pF(与振荡电路的匹配电容需保持一致,确保晶振稳定振荡);
  • 频率稳定度:±30ppm(覆盖工作温度范围-20℃~+70℃时的最大频偏,保证温度变化下时钟信号的稳定性);
  • 等效串联电阻(ESR):40Ω(中等水平,既保证振荡电路易启动,又降低信号干扰风险)。

三、封装与物理特性

HC-49S封装是无源晶振的经典直插封装形式,具备以下物理特点:

  • 尺寸小巧(约11.5mm×4.5mm×3.5mm),节省PCB空间;
  • 金属外壳封装,抗机械振动、抗电磁干扰能力较强;
  • 直插引脚设计,适合手工焊接或自动插件设备,安装流程成熟,降低生产难度。

四、工作环境与可靠性

该晶振的工作环境参数适配商业级应用场景:

  • 工作温度范围:-20℃~+70℃(满足室内电子设备的常规温度需求,如办公室、家庭环境);
  • 存储温度范围:-40℃~+85℃(可耐受短期极端温度变化,增强存储与运输可靠性);
  • 频率稳定性:结合常温频差与温度稳定度,整体时钟偏差控制在合理范围内,避免因时钟不准导致设备功能异常。

五、典型应用场景

TAXD12M2GLDBET8S的12MHz通用频率与稳定特性,使其适用于以下场景:

  1. 嵌入式系统与单片机:如51系列、STM32等MCU的外部时钟源,替代内部RC振荡以提升时钟精度;
  2. 工业控制设备:PLC模块、传感器节点的时钟参考,保证数据采集与控制指令的同步性;
  3. 消费电子:小型家电(如智能插座、加湿器)、遥控器、电子玩具的时钟信号;
  4. 通信模块:低速率无线通信(如蓝牙1.0、ZigBee早期版本)的载波时钟;
  5. 仪器仪表:简易示波器、信号发生器的基准时钟。

六、产品优势总结

  1. 通用适配性:12MHz频率覆盖多数主流电子设备的时钟需求,无需额外频率转换;
  2. 稳定可靠:±20ppm常温精度与±30ppm温漂,满足多数场景的时钟稳定性要求;
  3. 安装便捷:HC-49S直插封装,插件工艺成熟,降低生产与维修成本;
  4. 成本效益:无源晶振无需内置振荡电路,相比有源晶振成本更低,适合批量应用;
  5. 品牌保障:雅晶鑫作为专业晶振厂商,产品经过多轮可靠性测试,品质稳定。

以上为TAXD12M2GLDBET8S无源晶振的核心概述,可根据具体应用场景进一步匹配电路设计参数(如振荡电容、反馈电阻等),确保最佳性能发挥。

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
