TAXM16M2GLFBET2T无源贴片晶振产品概述

TAXM16M2GLFBET2T是雅晶鑫(YJX)推出的一款通用型无源贴片晶振,采用HC-49S-SMD封装,核心频率16MHz,专为消费电子、工业控制等常规场景设计,兼具成本可控与性能稳定的特点,是中低端电子设备时钟源的优选方案。

一、产品核心定位与类型说明

该晶振属于无源石英晶振,区别于内置振荡电路的有源晶振,需外接负载电容、振荡电阻等外围元件配合电路起振。型号中“TAXM”为雅晶鑫产品系列标识,“16M2”明确核心频率16MHz(后缀“2”对应20pF负载电容),“GLFBET2T”为封装及工艺代码,整体定位为中低精度、高性价比的通用时钟源,适配多数常规电子设备的计时/通信需求。

二、关键性能参数解析

  1. 频率与精度:核心频率16MHz,是MCU(如STM32F1系列)、低速率无线模块(如CC1101)的常用时钟频率;常温频差±30ppm(即频率偏移≤480Hz),满足大多数消费电子、工业控制的计时精度要求;
  2. 负载电容:额定负载电容20pF,无源晶振需外接匹配电容(通常为晶振两端各接10pF左右,需扣除线路寄生电容),否则会导致频率偏移或无法起振;
  3. 频率稳定度:±30ppm(温度范围内),当环境温度在-20℃~+70℃变化时,频率偏移不超过480Hz,适配常规室内/户外常温场景;
  4. 等效串联电阻(ESR):50Ω(典型值),ESR越低越易起振,该参数确保与主流MCU内部振荡器的兼容性,减少外围电路调试难度;
  5. 工作温度范围:-20℃~+70℃,覆盖家庭、办公、常规工业环境,不适合极端高温(如汽车发动机舱)或低温(如-40℃以下户外)场景。

三、封装形式与典型应用场景

1. 封装特点

采用HC-49S-SMD贴片封装,尺寸紧凑(约10.5×4.5×3.8mm),适配自动化SMT生产线,贴装效率高;相比直插HC-49S,更适合小型化电子设备(如智能手环、小型传感器模块),兼顾空间利用率与加工便捷性。

2. 典型应用

  • 消费电子:智能家居控制器(如WiFi模块时钟)、智能穿戴(如智能手环心率传感器时钟)、小型音频设备(如蓝牙音箱);
  • 工业控制:小型PLC(可编程逻辑控制器)、传感器节点(如温湿度传感器)、电机驱动模块;
  • 通信设备:低速率无线模块(如433MHz无线收发器)、简易路由器时钟源;
  • 汽车电子:非车载高温场景的辅助模块(如车载充电器控制电路)。

四、品牌与可靠性保障

雅晶鑫(YJX)是国内专注石英晶振研发生产的厂商,产品覆盖无源/有源晶振、温补晶振等系列,TAXM16M2GLFBET2T依托其成熟的石英晶体加工工艺,具备以下可靠性优势:

  • 无源晶振无有源器件老化问题,使用寿命可达10年以上;
  • ESR控制在50Ω内,减少起振失败概率,降低电路调试成本;
  • 出厂前经过高低温循环测试,确保参数一致性,适配批量生产需求。

五、选型与使用注意事项

  1. 负载电容匹配:必须使用20pF额定负载电容,实际外接电容需计算(公式:C外接=(20pF - 线路寄生电容)/2,线路寄生电容通常为25pF,故选810pF电容即可);
  2. 起振电路设计:配合MCU内部振荡器时,需确认MCU的晶振驱动能力(如STM32F1系列支持1~20MHz晶振,ESR≤100Ω即可);
  3. 贴装工艺:SMT回流焊温度需控制在260℃以内(峰值),避免过热导致晶体开裂;
  4. 环境适配:若应用场景温度超出-20~+70℃,需选择温补晶振(TCXO)或恒温晶振(OCXO)替代。

该晶振以高性价比和稳定性能,成为常规电子设备时钟源的优选方案,适配多数中低端产品的功能需求,可有效降低产品研发与生产成本。

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
