TAXD16M2GLDBET2S 无源晶振产品概述

一、产品基本识别信息

TAXD16M2GLDBET2S是一款无源直插晶振,由国内专业晶振厂家雅晶鑫(YJX)研发生产,采用行业经典的HC-49S封装。作为无源元件,它无需外部电源驱动,仅需匹配负载电容即可实现稳定振荡,是电子设备中最常用的时钟基准元件之一。

二、核心性能参数详解

该晶振的参数完全覆盖常规电子设备的时钟需求,关键指标如下:

  • 主频率:16MHz,是单片机、小型通信模块等设备的主流时钟基准频率;
  • 频差与稳定度:常温下频差控制在±20ppm(百万分之一),工作温度范围内频率稳定度为±30ppm。换算成实际偏差,16MHz晶振的频率波动最大不超过320Hz(16×10⁶×20×10⁻⁶),能满足大多数普通电子设备的精度要求;
  • 负载电容:20pF,无源晶振需外接两个匹配的负载电容(通常为20pF±5%)才能正常振荡,电路设计时需严格匹配此参数;
  • 等效串联电阻(ESR):40Ω,属于HC-49S晶振的优质范围——ESR越低,振荡电路起振越容易,长期工作稳定性越高;
  • 工作温度范围:-20℃~+70℃,覆盖工业环境的常规温度区间,可满足室内外非极端环境下的设备需求。

三、封装形式与安装优势

TAXD16M2GLDBET2S采用HC-49S直插封装,具备以下实用优势:

  • 体积小巧:典型尺寸约11.5mm×4.5mm×3.5mm,占用PCB空间小,适合小型电子设备;
  • 安装便捷:引脚间距为2.54mm,兼容常规面包板、PCB直插焊盘,手工焊接难度低,也可通过波峰焊实现批量生产;
  • 抗干扰性:直插封装的引脚布局比贴片更分散,一定程度上减少了电磁干扰对时钟信号的影响。

四、典型应用场景

结合16MHz的常用频率和参数特性,该晶振主要适用于以下场景:

  1. 单片机/MCU时钟源:如51系列单片机、STM32F1/F4系列低中端MCU,16MHz是这类芯片常用的外部高速时钟频率,可通过分频得到系统时钟(如72MHz);
  2. 小型电子设备:电视遥控器、智能家居控制器、小型电子钟、玩具电路等,对时钟精度要求不高但需稳定振荡的场景;
  3. 工业控制单元:小型PLC的辅助控制电路、传感器节点的时钟模块,工作温度范围覆盖工业环境的常规需求;
  4. 低速率通信模块:433MHz无线模块、蓝牙低功耗(BLE)模块的时钟基准,16MHz可分频得到常用的低速时钟(如32.768kHz)。

五、技术特性与可靠性

该晶振在技术上具备几个突出特点:

  • 无源设计优势:无需内置振荡电路,仅需外接两个20pF负载电容即可工作,电路设计简单,成本更低;
  • 稳定的频率特性:常温±20ppm的频差和温度范围±30ppm的稳定度,在温度变化时频率漂移可控,不会影响设备正常运行;
  • 可靠的ESR表现:40Ω的ESR确保振荡电路起振速度快,且长期工作中不易出现停振或频率漂移问题;
  • 品质保障:雅晶鑫作为专业晶振厂家,该产品经过常温老化、温度循环测试等常规可靠性测试,符合电子元器件的基本质量标准。

六、适用注意事项

使用TAXD16M2GLDBET2S时需注意以下细节:

  1. 负载电容匹配:必须外接两个20pF±5%的陶瓷电容(或NP0电容),电容参数不匹配会导致振荡频率偏差或无法起振;
  2. 焊接温度控制:直插封装焊接时,烙铁温度不宜超过350℃,焊接时间不超过3秒,避免高温损坏晶振内部石英晶体;
  3. 避免机械应力:安装时不要过度弯曲引脚,避免机械应力导致晶振频率漂移或损坏。

该晶振凭借稳定的性能、经典的封装和亲民的成本,成为普通电子设备时钟基准的优选元件之一。

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.
