TAXD13.56M2GLDAET2S无源晶振产品概述

TAXD13.56M2GLDAET2S 是雅晶鑫(YJX)推出的一款直插式无源石英晶体谐振器,采用经典HC-49S封装,核心频率为13.56MHz,广泛适配RFID、NFC、门禁等通用电子设备的频率需求,兼具成本优势与稳定性能。

一、基本信息与定位

该晶振属于无源谐振器(需外接振荡电路起振),品牌为国内晶振领域知名厂商雅晶鑫(YJX),型号全称TAXD13.56M2GLDAET2S,封装类型为HC-49S(直插2引脚)。其定位为通用型中精度晶振,适用于对频率稳定性要求适中、无需极端温宽的消费电子及小型工业场景。

二、核心参数详解

1. 频率特性

  • 标称频率:13.56MHz(国际通用ISM频段,免许可使用,是RFID、NFC等无线通信的核心工作频率);
  • 常温频差:±20ppm(实际频率与标称值的偏差≤13.56×20=271.2Hz,满足大多数通用设备的频率精度需求);
  • 频率稳定度:±30ppm(工作温度范围内的最大频率漂移,包含温度、电压波动等因素影响,确保-10℃~+60℃环境下性能稳定)。

2. 电气与机械参数

  • 负载电容:20pF(无源晶振需外接匹配电容,需选用20pF±5%的NPO陶瓷电容,避免频率偏移);
  • 等效串联电阻(ESR):60Ω(谐振时的等效电阻,越小越易起振且稳定性越好,60Ω在HC-49S封装中属于常规偏优水平);
  • 工作温度范围:-10℃~+60℃(适用于室内常温环境及一般户外轻度温差场景,不推荐极端低温/高温环境);
  • 封装尺寸:HC-49S标准尺寸(约11.5mm×4.5mm×3.5mm),直插2引脚设计,焊接兼容性强。

三、封装与应用场景

1. HC-49S封装优势

HC-49S是晶振领域的经典直插封装,具有以下特点:

  • 焊接方便:无需贴片设备,手工焊接或波峰焊均可实现,适合小批量试制及批量生产;
  • 抗干扰性:引脚短、封装结构紧凑,相比部分贴片封装,抗电磁干扰能力略强;
  • 成本可控:封装工艺成熟,物料成本低于小型化贴片晶振,适合中低端产品批量应用。

2. 典型应用场景

因13.56MHz为RFID/NFC的核心工作频率,该晶振主要应用于:

  • RFID设备:小区门禁读卡器、公交卡读写器、物流标签阅读器;
  • NFC模块:智能门锁、手机无线支付模块、蓝牙音箱的NFC配对功能;
  • 小型通信设备:低功率无线收发器、工业传感器节点;
  • 消费电子:电子秤、玩具遥控器、智能家居控制器(如温度传感器节点)。

四、选型与使用注意事项

  1. 负载电容匹配:必须使用20pF±5%的NPO陶瓷电容(温度系数≤±30ppm/℃),若电容偏差过大,会导致实际频率偏离标称值,影响设备正常工作;
  2. 焊接规范:烙铁头温度不超过350℃,单引脚焊接时间≤3秒,避免高温损坏晶振内部石英晶体;
  3. 环境限制:不得在-10℃以下或+60℃以上环境长期工作,否则频率漂移会超出规格范围;
  4. 机械应力避免:安装时不要过度弯曲引脚,避免挤压晶振外壳,防止石英晶体破裂或频率漂移。

五、性能优势总结

TAXD13.56M2GLDAET2S在通用场景下具有明显优势:

  • 频率精准:常温频差±20ppm满足90%以上消费电子/小型工业设备的精度需求;
  • 稳定性可靠:温度范围内稳定度±30ppm,避免因环境温度变化导致设备通信异常;
  • 性价比高:HC-49S封装成本低,适合批量采购;
  • 兼容性强:直插封装适配多种PCB设计,无需特殊工艺即可实现焊接。

该晶振是13.56MHz频率需求场景下的高性价比选型,尤其适合对成本敏感、无需极端温宽的通用电子设备。

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
