TAXM27.1412M4RLBDDT2T 无源贴片晶振产品概述

TAXM271412M4RLBDDT2T是雅晶鑫(YJX)推出的一款工业级无源石英贴片晶振,采用SMD3225-4P封装,以27.1412MHz为核心频率,兼顾高稳定性、低损耗与小体积特性,广泛适配通信、工业控制、消费电子等领域的时钟参考需求。

一、产品基本信息

  • 品牌与型号:雅晶鑫(YJX)旗下无源晶振,型号全称TAXM27.1412M4RLBDDT2T;
  • 类型:无源石英贴片晶振(无内置振荡电路,需外接匹配电容与振荡电路);
  • 封装规格:SMD3225-4P,即3.2mm×2.5mm贴片封装,4引脚设计,兼容自动化SMT贴装工艺,可有效节省PCB布局空间;
  • 核心定位:面向对频率精度、温宽有要求的中低端应用场景,平衡性能与成本。

二、核心电气参数详解

该晶振的关键参数直接决定应用适配性,具体如下:

  1. 频率特性:标称频率27.1412MHz(通信领域常用中频/时钟频率,如蓝牙1.0/2.0、部分WiFi模块参考时钟);常温(25℃)频差±10ppm,即频率偏差控制在±271.412Hz以内,满足多数电子设备时钟精度要求;
  2. 负载匹配:负载电容20pF,无源晶振需外接与标称值匹配的电容(通常为两个10pF电容并联),确保振荡频率稳定;
  3. 温漂控制:全温度范围(-30℃~+85℃)频率稳定度±20ppm,即温度变化时频率偏差最大不超过±542.824Hz,优于普通消费级晶振;
  4. 损耗特性:等效串联电阻(ESR)30Ω,属于无源晶振常规偏低水平,低ESR可减少振荡电路能量损耗,提升可靠性与起振速度;
  5. 环境适配:工作温度-30℃~+85℃,符合工业级温宽标准,适应户外、车载等复杂环境。

三、产品性能特点

  1. 高频率稳定性:常温频差±10ppm、全温稳定度±20ppm,避免因频率漂移导致通信丢包、控制时序错误;
  2. 低损耗设计:30Ω低ESR降低电路功耗,减少晶振自身发热,延长使用寿命;
  3. 宽温适应性:工业级温宽覆盖户外设备(智能电表、IoT节点)、车载电子(导航模块)等场景;
  4. 小体积易集成:SMD3225封装仅3.2×2.5mm,适合智能穿戴、小型家电等体积敏感产品;
  5. 无源设计易调试:明确20pF负载电容要求,电路设计无需复杂计算,降低研发生产难度。

四、典型应用场景

该晶振因频率、温宽与封装特性,适配以下场景:

  1. 通信设备:蓝牙模块、WiFi模块、射频收发器的时钟参考;
  2. 工业控制:PLC、传感器节点、工业网关的定时电路;
  3. 消费电子:智能手环、蓝牙耳机、智能插座的微控制器时钟;
  4. 车载电子:车载导航、车机系统、胎压监测模块的稳定时钟源;
  5. 物联网节点:低功耗IoT设备(智能门锁、环境传感器)的时钟参考。

五、选型与使用注意事项

  1. 负载电容匹配:严格按20pF设计外围电容(建议两个10pF陶瓷电容并联),电容偏差≤±5%;
  2. 焊接工艺:回流焊峰值温度≤260℃,回流时间≤10秒,避免高温损坏石英晶体;
  3. PCB布局:晶振靠近MCU时钟引脚(走线≤5mm),远离高频信号线减少干扰;
  4. 静电防护:操作时佩戴ESD手环,避免静电击穿;
  5. 存储条件:未焊接晶振存储于0℃~+40℃、湿度≤60%环境,防止受潮。

综上,TAXM27.1412M4RLBDDT2T是一款性价比突出的工业级无源贴片晶振,核心参数适配多领域应用,适合对频率精度、温宽有要求且需控制成本的电子设备设计。

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
