TAXM22.1184M4RLBCCT2T 贴片晶振产品概述

一、核心身份与典型应用场景

TAXM22.1184M4RLBCCT2T是雅晶鑫(YJX)推出的工业级SMD3225封装贴片晶振,核心频率为22.1184MHz——该频率是串口通信、以太网低速链路、工业PLC等领域的常用标准频率,广泛适配于对时钟精度和环境稳定性有要求的电子设备。

其典型应用场景包括:

  • 工业自动化:PLC可编程逻辑控制器、伺服驱动器、传感器模块的时钟源;
  • 通信终端:路由器、交换机、无线AP的低速数据链路时钟;
  • 消费电子:机顶盒、智能电表、车载信息娱乐系统的辅助时钟;
  • 医疗电子:小型监护仪、便携式医疗仪器的稳定时钟参考。

二、关键电气参数解析

该型号晶振的电气性能经过工业级优化,核心参数及实际意义如下:

2.1 频率精度与稳定性

  • 常温频差±10ppm:25℃环境下,实际频率与标称值(22.1184MHz)偏差≤±221Hz(计算:22.1184MHz×10ppm=221.184Hz),满足多数工业设备的时钟同步需求;
  • 频率稳定度±30ppm:覆盖-40℃~+85℃工作温度范围的频率漂移,最大偏移≤±663Hz(22.1184MHz×30ppm=663.552Hz),宽温下性能稳定。

2.2 负载与阻抗特性

  • 负载电容20pF:振荡电路需匹配总负载电容(含晶振引脚寄生电容)为20pF,是该型号标准要求,不匹配会导致频率偏移或停振;
  • ESR(等效串联电阻)40Ω:属于贴片晶振常规低阻范围,ESR越低越易起振、功耗越低,40Ω可保证电路稳定性。

三、机械与封装特性

该型号采用SMD3225-4P封装,适配现代电子设备小型化趋势:

  • 尺寸:3.2mm(长)×2.5mm(宽)×1.0mm(高),体积小巧,节省PCB空间;
  • 引脚:4引脚贴片式,兼容自动化SMT贴装,适合批量生产;
  • 材质:耐高温陶瓷封装,可承受回流焊高温(峰值240℃~250℃),抗电磁干扰(EMI)性能良好。

四、环境适应性与可靠性

TAXM22.1184M4RLBCCT2T的设计满足工业级环境需求:

  • 宽温工作:-40℃~+85℃,适应户外、工厂车间等温差场景,无需额外温度补偿;
  • 品牌可靠性:雅晶鑫作为国内专业晶振厂商,该型号经振动、冲击、老化测试,批量一致性好;
  • 抗干扰:陶瓷封装与低ESR设计,降低外界电磁干扰对时钟信号的影响。

五、选型与应用注意事项

为确保性能发挥,应用时需注意:

  1. 负载电容匹配:振荡电路总负载电容需校准至20pF,建议用示波器/频率计验证;
  2. 焊接工艺:回流焊温度曲线需符合SMD3225标准(峰值240℃~250℃,时间≤10秒),避免过热失效;
  3. 场景适配:适合中低精度需求的工业/通信场景,若需±1ppm以上精度或-55℃~+125℃宽温,需选其他型号;
  4. 采购建议:雅晶鑫该型号供货稳定,可先拿样品测试兼容性再批量下单。

该型号凭借稳定的性能、工业级宽温范围与小型化封装,成为工业控制、通信设备等领域的高性价比时钟源选择。

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
