TXM25M0004252DBCEO00T 产品概述
一、产品简介
TXM25M0004252DBCEO00T 是雅晶鑫（YJX）全国产贴片晶振，标准频率 25.000MHz，封装为 SMD2520-4P（2.5×2.0mm 四脚结构）。该器件针对工业级与消费级时钟源与频率参考设计，常温频差 ±10ppm，频率稳定度（含温度影响）为 ±30ppm，工作温度范围 -40℃至 +85℃，等效串联电阻（ESR）45Ω，推荐负载电容 10pF。
二、主要技术参数
- 频率：25.000 MHz
- 常温频差：±10 ppm
- 频率稳定度：±30 ppm（工作温度范围内）
- 负载电容：10 pF
- 等效串联电阻（ESR）：45 Ω
- 工作温度：-40℃ ~ +85℃
- 封装：SMD2520-4P（四脚）
- 品牌：YJX（雅晶鑫），国产制造
三、产品特点与优势
- 高频率精度高：常温 ±10ppm，适合对时钟精度有较高要求的系统。
- 宽温度范围：-40℃至+85℃，满足工业级环境使用。
- 贴片封装：SMD2520 小尺寸，便于高密度 PCB 布局与自动贴片生产。
- 低 ESR：45Ω 有利于振荡启动与稳定性控制，适配常见 MCU/PLL 输入级。
四、典型应用
适用于单片机/微控制器的主时钟、通信设备（以太网、无线模块）、时钟发生器、FPGA/ASIC 的参考时钟、消费电子与工业控制等需要 25MHz 基准频率的场景。
五、布局与外部电路建议
- 负载电容选择：对于对称电容 C1=C2，负载电容 CL 与封装寄生电容 Cstray 的关系为 CL ≈ C/2 + Cstray，故推荐外接电容 C ≈ 2×(CL − Cstray)。若 PCB 寄生电容约 2–5pF，则每侧电容建议约 10–16pF，常见取值为 12–16pF。
- 布局要点：晶振和两侧电容靠近振荡器管脚放置，减小走线长度；避免在晶振附近布置高速信号线和大电流回流；将地平面完整铺铜并在晶振附近做好地回流。
- 启动与驱动：驱动电平和负载需按目标振荡器（MCU/IC）推荐值配置，保证稳定启动；如遇启动困难，可在电容和布线上优化以降低寄生影响。
六、存储与注意事项
- 注意防静电保护（ESD），避免直接碰撞或压迫晶体体。
- 建议按回流焊温度曲线进行焊接，避免超温或长时间加热（参照客户焊接工艺）。
- 长期存放请保持干燥，避免潮湿环境。
七、订购信息

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.
