TX322540M4FBCE2T 贴片晶振产品概述

一、产品基本定位与品牌背景

雅晶鑫(YJX)推出的TX322540M4FBCE2T属于工业级贴片石英晶振,针对对时钟稳定性、小尺寸有明确需求的电子设备设计,核心频率40MHz,适配消费电子、工业控制、通信设备等多类场景,是一款兼顾性能与成本的成熟产品。

二、关键性能参数详解

1. 频率精度与稳定度

  • 常温频差:±10ppm(25℃环境下),满足大多数电子设备对时钟同步的基础要求(如蓝牙通信的时序精度、单片机指令周期的稳定性);
  • 全温稳定度:±30ppm(覆盖-40℃~+85℃),可有效抑制极端温度下的频率漂移,适配北方冬季户外终端、南方高温车间设备等场景。

2. 负载电容与ESR

  • 负载电容:12pF,为行业主流设计值,可直接匹配单片机(如STM32)、通信模块的内置电容,或外接12pF陶瓷电容,降低电路调试难度;
  • 等效串联电阻(ESR):30Ω,低ESR设计可提升振荡启动速度(典型启动时间<1ms),减少信号损耗,增强抗电磁干扰能力(EMI)。

3. 工作温度范围

  • -40℃~+85℃,达到工业级温度标准,可稳定运行于户外、车间、车载辅助设备(非严苛车载级,适配一般车内环境)等场景。

三、封装与物理特性

采用SMD3225-4P贴片封装,具体尺寸为:

  • 平面尺寸:3.2mm×2.5mm(符合“3225”封装代号定义);
  • 高度:0.8mm(典型值);
  • 引脚:4脚(两侧各2脚),焊接稳定性强,适配自动化SMT贴装,可有效节省PCB布局空间,满足智能手表、蓝牙耳机等小型化产品的设计需求。

四、典型应用场景

  1. 消费电子:智能穿戴(智能手表、手环的时钟模块)、蓝牙耳机(蓝牙5.0/5.1通信时序控制)、智能家居(智能音箱、网关的网络同步);
  2. 工业控制:PLC模块、传感器节点(温湿度传感器、工业摄像头)、工业物联网终端(数据采集设备的时钟同步);
  3. 通信设备:小型WiFi路由器、蓝牙模块、低功耗LoRa终端(40MHz频率可满足通信协议的时钟需求);
  4. 车载辅助:车载USB充电器(时钟控制)、车载蓝牙适配器(适配-20℃~+70℃的车内环境)。

五、产品优势总结

  1. 宽温稳定:-40℃~+85℃的温度范围,解决极端环境下的时钟漂移问题,无需额外温补电路;
  2. 小尺寸适配:SMD3225封装,贴合当下电子设备“轻薄化”趋势,节省PCB空间;
  3. 低ESR高可靠:30Ω低电阻减少信号损耗,提升振荡稳定性,延长产品使用寿命;
  4. 易匹配设计:12pF负载电容适配主流电路,降低研发调试成本;
  5. 品牌保障:雅晶鑫作为国内晶振厂商,产品经过市场验证,批量供应稳定性有保障。

六、应用电路注意事项

  • 负载电容匹配:需在晶振两端外接12pF陶瓷电容(或与电路内置电容匹配后总电容为12pF),避免频率偏差;
  • 振荡电阻选择:可串联10Ω~33Ω匹配电阻(根据单片机型号调整),防止振荡过强;
  • PCB布局:晶振尽量靠近单片机时钟引脚,减少走线长度(<10mm),避免电磁干扰。

TX322540M4FBCE2T凭借宽温稳定、小尺寸、高精度等特点,可广泛应用于多类电子设备,是研发人员在时钟模块设计中的可靠选择。

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
