TAXM13.56M2ILDBET2T 贴片晶振产品概述

TAXM13.56M2ILDBET2T是雅晶鑫(YJX)针对高频通信与识别场景推出的一款13.56MHz石英贴片晶振,采用HC-49S-SMD封装,兼顾精度、可靠性与批量生产便利性,是RFID阅读器、智能门禁等设备的高性价比时钟源选择。

一、产品基本定位与核心属性

这款晶振属于普通石英谐振器(无温补/压控功能),核心定位为高频(13.56MHz)场景的稳定时钟基准。13.56MHz是国际RFID高频段(ISO 14443、ISO 15693协议)的标准频率,天然适配各类RFID相关设备;同时,贴片封装支持自动化SMT贴装,适合大规模量产,降低生产环节人工成本。

二、关键性能参数详解

性能参数直接决定晶振在实际场景中的表现,TAXM13.56M2ILDBET2T的核心参数适配高频应用需求,具体如下:

  1. 频率与常温精度
    标称频率13.56MHz,常温(25℃±2℃)频差±20ppm(百万分之一)。换算为实际偏差:13.56MHz×20×10⁻⁶=±271.2Hz,可满足RFID阅读器射频信号同步要求,避免因频率偏移导致识别失败或误判。

  2. 温度稳定性
    工作温度-20℃~+70℃,对应频率稳定度±30ppm。温度变化范围内频率最大偏差±406.8Hz,能适应室内外常规环境(如户外门禁、商场RFID盘点设备),无需额外温补电路即可保证基本稳定性。

  3. 负载电容匹配
    负载电容20pF,是晶振与振荡电路的核心匹配参数。若电路等效负载(外接电容+寄生电容)偏离较多,会导致频率偏移甚至无法起振,设计时需通过两个40pF电容串联(等效20pF)实现精准匹配。

  4. 等效串联电阻(ESR)
    ESR为60Ω,属于石英晶振较低水平。较低ESR可降低振荡电路驱动功率(减少功耗),提升启动速度与长期可靠性——ESR过高易导致振荡不稳定、功耗增加,甚至缩短寿命。

三、封装与典型应用场景

1. 封装特性

HC-49S-SMD为贴片式封装,尺寸紧凑(远小于插件式),支持标准SMT回流焊工艺,适合小型化设备(如手持RFID阅读器、智能卡读卡器)设计,同时避免插件式的人工焊接成本。

2. 典型应用场景

  • RFID高频设备:超市商品标签阅读器、图书馆图书盘点器、物流仓储扫码枪;
  • 智能门禁系统:小区/办公楼刷卡开门控制器、电梯刷卡组件;
  • 无线通信模块:蓝牙低功耗(BLE)辅助时钟、短距离无线传输模块;
  • 小型消费电子:智能手环射频识别模块、便携式POS机刷卡组件。

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,拥有10余年行业经验,产品符合RoHS、REACH环保标准,适合出口及国内环保要求。TAXM系列晶振经过高低温循环、振动测试等可靠性验证,平均无故障时间(MTBF)达数十万小时,可保证长期稳定运行。

五、选型与使用注意事项

  1. 负载电容匹配:需计算晶振引脚寄生电容(2~5pF),外接电容调整为2×(20pF-寄生电容),确保总负载接近20pF;
  2. 焊接工艺:回流焊峰值温度≤260℃,持续时间≤10秒,避免过热损坏石英片;
  3. 环境适配:若温度超出-20℃~+70℃(如工业高温),需更换温补/压控晶振;
  4. 存储要求:未焊接晶振存储在湿度<60%的干燥环境,存储周期不超过12个月,避免引脚氧化。

总结

TAXM13.56M2ILDBET2T凭借稳定的13.56MHz频率、合理精度参数、贴片封装便利性,成为高频RFID及相关通信设备的高性价比时钟源。其适配常规工作环境,支持批量自动化生产,适合对成本敏感且需要稳定时钟基准的中低端应用场景。

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
