TX49M13.52127M2DDBE2T 产品概述
一、产品概述
YJX（雅晶鑫）TX49M13.52127M2DDBE2T 为贴片式谐振晶体（HC-49S-SMD 封装），标称频率 13.52127 MHz，适用于对频率稳定性与体积有要求的高频时钟与射频前端电路。产品以工艺稳定、频率一致性好为特点，适合批量化装配与回流焊流程。
二、主要参数
- 晶振类型：贴片晶振（HC-49S-SMD）
- 频率：13.52127 MHz
- 常温频差：±20 ppm（出厂初始容差）
- 频率稳定度（含温度、老化等）：±30 ppm
- 负载电容：10 pF
- 等效串联电阻（ESR）：40 Ω
- 工作温度：-20 ℃ ~ +70 ℃
- 品牌：YJX（雅晶鑫）
三、主要特点
- 高频稳定：专为13.52 MHz 附近应用优化，频率一致性高。
- 小型贴片封装：HC-49S-SMD 便于自动化贴装与回流焊接。
- 低至中等 ESR：40 Ω 满足常见微控制器和射频振荡器的驱动要求。
- 宽温区间：-20~+70℃ 满足大多数商用和工业环境。
四、典型应用
- HF 射频/NFC 与近场通信设备（须验证系统对频率偏差的容忍度）
- 射频读写器、RFID 前端模块
- MCU/数字系统时钟源与精密振荡参考
- 测试与测量设备的高频基频参考
五、设计与使用建议
- 负载电容匹配：晶体标称 CL=10 pF。按公式 CL = (C1*C2)/(C1+C2)+Cstray 计算，常见板上寄生电容 2–5 pF 时，建议 C1=C2 取 16–22 pF（常用 18 pF）。最终值请在目标电路中验证频率偏差。
- 驱动电平：按系统振荡器内部驱动能力选型，避免过驱动导致老化加速。
- 焊接工艺：推荐按厂家回流焊温度曲线；避免长时间高温暴露以降低频率漂移。
- 布局：晶体附近避免大电流回路与强噪声源，参考厂商推荐焊盘尺寸与地线处理。
- 静电防护与储存：存储与装配过程中注意ESD 防护，避免潮湿环境长时间存放。
六、品质与订购
YJX 对出厂产品通常进行频率、ESR 与负载匹配测试，批次可提供检验报告与样品验证。订购时请注明型号全称、首选频差与数量，批量采购可咨询交期与可追溯测试数据。若用于对频率要求极高的系统，建议索取样品并进行老化与温漂验证。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
