TAXM27.1412M4RHBDDT2T 无源贴片晶振产品概述

一、产品基本信息

TAXM27.1412M4RHBDDT2T是雅晶鑫(YJX)推出的无源贴片晶体谐振器,无内置振荡电路,需外接匹配电容与振荡电路协同工作。产品采用SMD3225-4P封装(3.2mm×2.5mm贴片式4引脚),型号中“27.1412M”明确核心频率为27.1412MHz,是针对特定通信、时钟场景优化的标准化频率器件。

二、核心性能参数解析

该晶振的关键参数直接决定适用场景,具体如下:

  1. 频率特性:标称频率27.1412MHz,常温(25℃左右)频差±10ppm(即频率偏差范围为27.1412MHz±271.412Hz),精度满足多数中低端通信、时钟同步需求;
  2. 负载电容:15pF,为晶振工作时需匹配的外部电容值,电路设计需保证两端并联电容总容量为15pF,避免频率偏移;
  3. 等效串联电阻(ESR):30Ω,ESR越低则信号损耗越小、振荡稳定性越高,30Ω在同封装无源晶振中属于中上游水平;
  4. 温度特性:工作温度范围-30℃~+85℃,频率稳定度±20ppm(温度变化时最大频率偏差±542.824Hz),可适应室内外环境波动;
  5. 无源设计:无需额外供电,电路集成度高,可靠性强,成本低于有源晶振。

三、封装与引脚说明

产品采用SMD3225-4P封装,尺寸为3.2mm(长)×2.5mm(宽)×0.8mm(厚,典型值),属于小型化贴片封装,适配自动化贴装生产线,可节省PCB空间,适合便携设备。

4引脚设计中,2个引脚为晶体有效电极(外接振荡电路),另外2个为机械支撑或dummy引脚(部分型号含接地设计),实际应用需参考雅晶鑫官方 datasheet 确认引脚定义。

四、产品优势与适用场景

4.1 核心优势

  • 小型化便携:3225封装体积小,适配智能穿戴、蓝牙耳机等便携终端;
  • 稳定可靠:低ESR(30Ω)+ 宽温范围(-30℃~+85℃),减少环境对频率的影响;
  • 成本可控:无源设计无需内置振荡电路,性价比高,适合量产;
  • 兼容性强:15pF负载电容为常用值,多数振荡电路可直接匹配,无需额外优化。

4.2 典型应用场景

  • 短距离无线通信:27MHz频段遥控器(玩具、智能家居)、无线音频模块;
  • 音视频终端:机顶盒、DVD播放器、智能电视的时钟参考源;
  • 工业控制:小型PLC、传感器节点等轻量工业设备(宽温适配现场环境);
  • 便携电子:智能手表、运动手环的辅助时钟模块;
  • 车载辅助设备:车载蓝牙适配器、倒车雷达控制器(温度范围满足车载基本需求)。

五、注意事项

  1. 负载电容匹配:外接电容总容量需为15pF,避免频率偏差过大;
  2. 贴装工艺:采用合适回流焊温度曲线,避免过热损坏晶体;
  3. 静电防护:生产过程需注意ESD防护,避免晶体损坏;
  4. 存储条件:存储于常温干燥环境(0℃~+40℃,湿度≤60%RH),避免高湿、高盐雾环境。

该产品凭借小型化、稳定可靠的特性,可满足多数消费电子、轻量工业场景的频率需求,是低成本时钟/通信应用的优选器件。

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
