TAXM147456M2QLDBET1T 产品概述
一、产品简介
TAXM147456M2QLDBET1T 是雅晶鑫（YJX）出品的一款贴片晶振，封装为 SMD5032-2P（5.0 × 3.2 mm），标称频率 14.7456 MHz。该器件适用于对串口波特率和定时精度有较高要求的微控制器、通信模块及消费类电子产品，提供稳定的频率源和良好的可焊性，便于表面贴装生产工艺集成。
二、主要规格
- 频率：14.7456 MHz
- 常温频差（初始容差）：±20 ppm
- 频率稳定度：±30 ppm
- 负载电容：20 pF
- 等效串联电阻（ESR）：60 Ω（典型/上限）
- 工作温度范围：-20 ℃ ～ +70 ℃
- 封装：SMD5032-2P（贴片）
- 品牌：YJX（雅晶鑫）
三、典型特性与优势
- 精确频率：14.7456 MHz 是常用于 UART/串口分频以获得标准波特率（例如 115200、57600 等）的频率，便于系统时钟设计与兼容。
- 高可靠性：表面贴装封装便于自动化焊接和批量生产，稳定性满足多数商业与工业级应用需求。
- 容差与稳定度匹配设计：常温±20 ppm 与全温±30 ppm 的组合，在多数控制与通信场景下能保证良好的时序精度。
- 封装小巧：SMD5032 体积小，便于在 PCB 布局中节省空间。
四、推荐使用与电路注意事项
- 负载电容匹配：若晶体标称 CL = 20 pF，按等效电容公式考虑 PCB 与引脚寄生电容（典型 2–5 pF），建议外加两侧耦合电容各约 30–36 pF（具体值请根据所用晶体管/振荡器电路与板上寄生实际测量调整）。
- 焊接工艺：支持常规 SMD 回流焊工艺，请参考厂方回流曲线与湿热/温度循环可靠性规范。
- 安装与布局：晶体应尽量靠近 MCU 或振荡器输入端，走线短且对称，避免紧邻大电流或高频干扰源。
- ESD 与静电防护：储存与贴装过程中注意防静电，避免因静电或过驱导致性能退化。
五、典型应用
- MCU 时钟与串口通信（UART）源
- 工业控制与嵌入式系统定时
- 网络通信模块、调制解调器、消费电子与物联网终端
（注：器件工作温度为 -20 ℃ ～ +70 ℃，适合商用与一般工业环境；若用于极端温度环境请咨询厂方或选用高温等级产品。）
六、包装与订购建议
- 常见提供卷带盒（Tape & Reel）适配 SMT 贴片机，如需散装或特殊包装请与供应商确认。
- 订购时请注明型号全称 TAXM147456M2QLDBET1T、所需数量与包装形式，并确认交期与质量认证要求。
本产品在成本、体积与时序精度之间具有良好平衡，适合对串口波特率和常温频率精度有明确要求的批量生产应用。若需更严格温度范围、老化或驱动等级等参数，请提供具体应用环境以便推荐更适合的型号或提供技术支持。

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.
