TAXD13.52127M2GDDBET2S无源晶振产品概述

一、产品基本信息

TAXD13.52127M2GDDBET2S是雅晶鑫(YJX) 推出的一款直插式无源晶振,采用行业通用的HC-49S封装,属于低成本、高可靠性的时钟参考元件。该型号针对13.52127MHz特定频率优化,适配多种需要精准时钟信号的电子设计场景,尤其适合传统插件工艺的电路开发。

二、核心参数深度解析

晶振核心参数直接决定应用适配性,以下是该型号关键参数及实际意义:

(1)标称频率:13.52127MHz

该频率接近13.56MHz(ISM频段常用频率),广泛应用于高频RFID、蓝牙辅助时钟、小型通信模块等场景,是消费电子与工业控制中常见的时钟基准频率。

(2)常温频差:±20ppm

频差指常温(25℃左右)下实际输出频率与标称频率的偏差,ppm为“百万分之一”。计算可得:
偏差范围 = 13.52127MHz × 20×10⁻⁶ ≈ ±270Hz
该精度可满足大多数单片机、电子钟、小型传感器节点的时钟需求,无需额外温补电路。

(3)负载电容:10pF

无源晶振需外接两个负载电容(晶振两端各接一个到地),电容值需与标称负载电容匹配。若不匹配,实际输出频率会偏离标称值,设计时需严格选用10pF电容(误差≤5%即可)。

(4)频率稳定度:±30ppm

指工作温度范围内(-20℃~+70℃) 的频率最大变化量,反映晶振抗温度干扰能力。该参数下,温度变化导致的频率偏差≈±406Hz,可稳定适配室内环境、一般工业常温场景(无需宽温要求)。

(5)等效串联电阻(ESR):40Ω

ESR是晶振内部等效电阻,值越低越易起振。40Ω属于中等偏优范围,可保障晶振在大多数电路中快速起振,避免“不起振”“停振”问题。

(6)工作温度:-20℃~+70℃

覆盖工业级常温范围,适用于室内电子设备、小型工业控制器、消费电子产品等,不建议在极端低温(<-20℃)或高温(>+70℃)环境下使用。

三、封装与物理特性

该晶振采用HC-49S直插封装,具体物理特性如下:

  • 引脚数:2脚(无源晶振标准配置)
  • 标准尺寸:长11.5mm × 宽4.7mm × 高3.8mm(行业通用)
  • 焊接方式:插件焊接(适合手工焊接或传统插件生产线)

直插封装优势在于易焊接、易维护——无需SMT贴装设备,降低生产门槛;若出现故障,可直接替换,维修成本低。

四、应用场景与性能优势

(1)典型应用场景

  • 高频RFID模块:13.52127MHz接近13.56MHz(HF RFID核心频率),可作为RFID读写器/标签的时钟基准;
  • 单片机系统:适配51单片机、STM32等MCU的外部晶振(需匹配10pF负载电容);
  • 消费电子产品:电子钟、智能玩具、遥控器的时钟参考;
  • 小型工业控制:传感器节点、小型PLC的时钟源。

(2)核心性能优势

  1. 成本可控:无源晶振无主动驱动电路,价格远低于有源晶振,适合批量生产;
  2. 可靠性高:HC-49S封装防护性好,可避免灰尘、振动对晶振的影响;
  3. 起振稳定:40Ω低ESR保障电路起振可靠性,减少调试难度;
  4. 精度适配:±20ppm常温精度+±30ppm温漂,满足90%以上日常电子设计的时钟需求。

五、使用注意事项

  1. 负载电容匹配:必须外接两个10pF电容(晶振两端到地),电容误差建议≤5%;
  2. 焊接温度控制:手工焊接时,烙铁温度不宜超过350℃,焊接时间≤3秒,避免损坏石英晶体;
  3. 环境防护:避免晶振暴露在潮湿、腐蚀性气体环境中,防止引脚氧化;
  4. 抗干扰设计:晶振附近尽量远离大功率电感、开关电源等干扰源,可通过敷铜隔离提升稳定性。

综上,TAXD13.52127M2GDDBET2S是一款高性价比、易使用的直插无源晶振,适配多种需要13.52127MHz时钟的电子设计,尤其适合传统插件工艺的项目开发。

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.
