TX322512.288M4FBDD2T 贴片晶振产品概述

一、产品核心身份与应用定位

TX322512.288M4FBDD2T是雅晶鑫(YJX)推出的SMD3225封装石英贴片晶振,核心频率为12.288MHz,属于中高精度时钟基准器件。该型号针对工业控制、物联网终端、通信模块(蓝牙/WiFi/LoRa)、消费电子(智能穿戴、机顶盒、智能家居) 等场景优化,12.288MHz频率因与串口通信(UART)、音频采样(48kHz倍频)等常用功能的兼容性,成为众多电路设计的首选基准源。

二、关键电气性能参数详解

(一)频率与精度

  • 标称频率:12.288MHz——标准串口通信波特率(如115200bps、9600bps)的核心分频基准(12.288M÷128=96000Hz,再分频可匹配常用波特率),同时适配48kHz音频采样的倍频需求(12.288M=48kHz×256);
  • 常温频差:±10ppm——常温(25℃)下频率偏差≤±122.88Hz,满足工业级通信不丢包、音频采样无失真的精度要求;
  • 频率稳定度:±20ppm——工作温度范围内(-30℃~+85℃)频率变化≤±245.76Hz,覆盖宽温场景(如户外传感器、车载设备)的稳定性需求。

(二)负载与阻抗

  • 负载电容:12pF——SMD3225封装的主流匹配值,兼容多数MCU、通信芯片的晶振负载设计,无需额外复杂匹配电路;
  • 等效串联电阻(ESR):50Ω——内阻处于中等偏低水平,启动速度快(<10ms)、工作功耗低(典型值<1mW),适合低功耗物联网节点、电池供电设备。

三、封装与物理特性

该晶振采用SMD3225-4P封装,物理尺寸为3.2mm×2.5mm×0.8mm(长×宽×高),4引脚贴片式设计,支持自动化SMT贴装,可直接焊接于PCB表面。小体积特性使其适配小型化设备(如智能手环、微型传感器),有效节省PCB空间,同时避免插针晶振的体积占用与焊接复杂度。

四、环境适应性与可靠性

  • 工作温度范围:-30℃+85℃——覆盖工业级温度区间(远超消费级0℃70℃),可稳定工作于户外低温环境、车载高温环境及温差变化较大的工业现场;
  • 可靠性设计:采用全密封陶瓷封装,有效隔绝水汽、灰尘对晶振的影响,抗振动(10g~2000Hz)、抗冲击(1000g/0.1ms)性能符合工业级标准,可应对设备运输、现场安装的机械应力;
  • 环保合规:符合RoHS、REACH等环保指令,无铅焊接兼容,适配绿色制造需求。

五、品牌背景与质量保障

雅晶鑫(YJX)是国内专注石英晶振研发生产的专业厂商,拥有10余年晶振制造经验,产品线覆盖石英晶振、温补晶振(TCXO)、压控晶振(VCXO)等,产品广泛应用于通信、工业控制、汽车电子等领域。TX322512.288M4FBDD2T经过24小时老化测试、批次一致性筛选,确保每颗产品的性能参数符合规格书要求,供货周期稳定(常规1~2周,紧急订单可支持3天交付),为客户提供可靠的时钟基准解决方案。

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
