TAXM24M4RLBCCT2T 无源贴片晶振产品概述

一、产品基本属性

TAXM24M4RLBCCT2T是雅晶鑫(YJX)品牌推出的一款无源贴片晶振,采用SMD3225-4P封装(3.2mm×2.5mm尺寸,4引脚表面贴装),属于工业级通用时钟源器件。无源晶振的核心特点是无需内置有源振荡电路,需配合外部振荡电路(如MCU内置OSC模块或专用振荡芯片)实现稳定振荡,具备结构简单、可靠性高、寿命长的优势,适合对成本敏感且长期稳定工作的电子设备。

二、核心性能参数详解

该型号晶振的关键性能参数可满足多数中低端到中端电子设备的时钟需求,具体参数及意义如下:

  1. 标称频率:24MHz
    是晶振的基准振荡频率,广泛应用于微控制器(MCU)、通信模块等设备的时钟基准,24MHz为常见通用频率,兼容性强。
  2. 常温频差:±10ppm
    指25℃常温下,实际振荡频率与标称频率的偏差范围(1ppm=1×10⁻⁶)。±10ppm意味着24MHz的实际频率偏差为±240Hz,精度满足普通消费电子、工业控制的基本频率要求。
  3. 负载电容:20pF
    是晶振振荡电路需匹配的外部电容值(通常为两个并联电容的总和),若负载电容匹配偏差过大,会导致实际振荡频率偏离标称值,需在PCB设计中严格按照20pF要求配置匹配电容。
  4. 频率稳定度:±50ppm
    指全工作温度范围内(-40℃~+85℃),频率相对于常温(25℃)的最大变化量。±50ppm即24MHz的频率变化为±1200Hz,可适应工业环境的温度波动,保证设备在宽温下的时钟稳定性。
  5. 等效串联电阻(ESR):80Ω
    是晶振等效为串联电路时的电阻值,ESR直接影响振荡幅度和电路稳定性:ESR越低,振荡越稳定,但成本越高;该型号80Ω的ESR属于无源晶振的典型值,可满足一般振荡电路的启动和稳定要求。
  6. 工作温度范围:-40℃~+85℃
    覆盖工业级温度区间,可在户外、车间等恶劣环境下长期工作,避免因温度过高或过低导致频率漂移甚至停振。

三、封装与物理特性

采用SMD3225-4P封装,具有以下特点:

  • 小型化:3.2mm×2.5mm的尺寸适合高密度PCB布局,可用于可穿戴设备、小型物联网模块等对体积敏感的产品;
  • 贴片式设计:4引脚表面贴装,兼容自动化贴片生产线,焊接效率高,降低生产工艺难度;
  • 无引脚氧化风险:贴片封装避免了插针式晶振的引脚氧化问题,提高长期可靠性。

四、环境适应性与可靠性

  1. 宽温稳定性:-40℃~+85℃的工作温度范围,满足工业控制、户外通信设备等场景的温度要求;
  2. 无源结构优势:无内置有源器件(如晶体管),故障率低,寿命可达数万小时,适合长期连续工作的设备;
  3. 抗干扰性:无源晶振的振荡电路依赖外部匹配,可通过电路设计优化抗电磁干扰(EMI)能力,适合复杂电磁环境。

五、典型应用领域

TAXM24M4RLBCCT2T因性能均衡、成本适中,广泛应用于以下场景:

  1. 物联网(IoT)模块:蓝牙5.0模块、WiFi模块、LoRa模块的时钟源,为数据传输和MCU运行提供稳定基准;
  2. 消费电子:智能手环、智能手表、便携式音箱等可穿戴/小型电子设备的MCU时钟;
  3. 工业控制:PLC模块、工业传感器(如温度、压力传感器)的数据采集模块时钟,适应车间宽温环境;
  4. 小型通信设备:家用路由器、小型基站(小站)的辅助时钟,保证数据传输的时序准确性;
  5. 车载辅助设备:车载USB充电器、车载蓝牙适配器等非核心车载电子的时钟源(需确认具体车载标准,该型号工业级温度可满足部分车载场景)。

六、产品优势总结

该型号晶振兼顾了小型化、宽温适应性、成本控制三大核心优势,适合对时钟精度要求中等、体积敏感且需长期稳定工作的电子设备,是工业控制、物联网、消费电子领域的高性价比无源时钟源选择。

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
