T49S12MLDBE2X 直插石英晶振产品概述

一、产品定位与核心功能

T49S12MLDBE2X是YJX(雅晶鑫)旗下一款通用型直插石英晶振,核心定位为各类电子电路提供稳定可靠的12MHz基准时钟信号。其适配场景覆盖消费电子、工业控制、小型通信、仪器仪表等多个领域,是8位/16位MCU、传感器模块、小型通信设备的经典时钟源选择。

二、核心参数详解

该型号的参数设计兼顾通用性与实用性,关键指标如下:

  • 频率:12MHz(市场普及度最高的时钟频率之一,兼容主流MCU内置振荡器);
  • 常温频差:±20ppm(满足多数普通电子设备的时钟精度要求,避免时序紊乱);
  • 负载电容:20pF(行业通用匹配值,与多数MCU振荡器电路内置电容兼容,简化设计);
  • 等效串联电阻(ESR):40Ω(处于HC-49S封装晶振的合理区间,提升谐振效率、降低功耗);
  • 频率稳定度:±30ppm(全温范围覆盖,适应温度变化下的时钟稳定性);
  • 工作温度:-20℃~+70℃(覆盖室内常温及轻度户外环境);
  • 封装:HC-49S(金属直插封装,抗干扰性强,焊接便捷)。

三、封装与引脚配置

采用HC-49S金属直插封装,是石英晶振的经典结构:

  • 尺寸:约11.5mm(长)×4.5mm(宽)×3.5mm(高),引脚间距2.54mm,兼容标准面包板与PCB直插焊盘;
  • 引脚特性:无极性设计(两个引脚可直接焊接,无需区分正负极),降低电路设计与焊接复杂度;
  • 屏蔽优势:金属外壳具备基础电磁屏蔽能力,减少外部干扰对时钟信号的影响。

四、典型应用场景

该型号因通用性强,广泛应用于以下场景:

  1. 单片机/MCU系统:51系列、STM32F1部分型号的主时钟源,实现1μs指令周期,满足小型控制任务需求;
  2. 工业控制:PLC辅助模块、传感器信号处理电路的时钟,保证数据采集与传输同步;
  3. 消费电子:智能插座、加湿器、早教机等小型家电的核心控制电路;
  4. 小型通信:低速率蓝牙(BLE 4.0)、WiFi辅助时钟,或简易无线模块的基准频率;
  5. 仪器仪表:手持测量仪、小型示波器的辅助时钟,提升数据显示稳定性。

五、性能优势分析

  1. 通用频率适配性:12MHz是超过60%主流MCU的默认兼容频率,无需额外频率转换,降低电路升级成本;
  2. 匹配设计简化:20pF负载电容与多数MCU内置振荡器匹配,避免因电容不匹配导致的频率偏移,减少调试时间;
  3. 低功耗与高稳定性:40Ω低ESR保证谐振效率,同时降低晶振功耗,延长电池供电设备续航;
  4. 抗干扰与抗振动:HC-49S金属封装抗电磁干扰能力优于贴片,抗振动性能适合轻微振动场景(如小型打印机)。

六、环境适应性与可靠性

  • 温度适应性:工作温度-20℃+70℃,存储温度-40℃+85℃(满足长期库存与运输要求);
  • 长寿命设计:石英晶振固有特性决定使用寿命长,YJX批量测试保证一致性;
  • 环保合规:符合RoHS标准,采用无铅焊接工艺,兼容现代电子设备环保要求。

七、品牌与品质保障

YJX(雅晶鑫)是国内专注石英晶振研发的成熟品牌,T49S12MLDBE2X经过出厂全检(频率精度、温度循环、振动测试等),具备批量供应能力,适合量产项目采购。其产品广泛应用于家电、工业控制等领域,口碑稳定。

该型号以“通用、稳定、易集成”为核心特点,是多数电子电路时钟源的高性价比选择。

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
