X1E000021064800 产品概述
一、概述
X1E000021064800 为爱普生（EPSON）系列贴片晶体谐振器（晶振），工作频率为 25.000 MHz，属于基频（FUND）4 引脚 Mini‑CSMD 封装（T/R 卷带包装），适用于对频率精度和温度稳定性有较高要求的数模混合、通信与时钟系统。器件在工业级温度范围内工作，适合嵌入式主控、网络设备、无线模块等应用。
二、主要技术参数
- 标称频率：25.000 MHz
- 常温频差（初始容差）：±10 ppm
- 频率稳定度（温度与老化等综合）：±20 ppm
- 负载电容（CL）：18 pF
- 等效串联电阻（ESR）：40 Ω（典型/最大）
- 工作温度范围：-40 ℃ ～ +85 ℃
- 振荡模式：Fundamental（基频）
- 封装/引脚：4‑Pin Mini‑CSMD，卷带供料（T/R）
三、产品特点
- 高频率精度高：±10 ppm 初始容差，可满足对时钟精度敏感的系统要求。
- 良好温稳与长期稳定性：±20 ppm 的稳定度在工业温度范围内表现可靠。
- 小型贴片封装和卷带包装，利于自动贴装与量产。
- 适合基频振荡器设计，ESR 与负载电容配合易于达到启动与稳定工作条件。
四、典型应用
- 单片机/微控制器时钟源（MCU、DSP）
- 通信设备时钟与参考（以太网 PHY、USB、MCU 外围）
- 无线模块与射频前端本振参考（需根据相位噪声要求评估）
- 工业控制、测试测量设备时钟参考
五、使用与焊接建议
- 负载电容匹配：若采用对称电容，理论每侧电容约为 C1=C2≈2·CL−Cstray，常见实用值在 27–33 pF 范围，需根据 PCB 板上寄生电容调整。
- 布局：晶振接近振荡器输入脚，避开高速信号线与噪声源，接地应做短回流路径。
- 焊接：遵循厂家推荐回流曲线，避免过高温度/时间或重复回流。卷带包装适配自动贴装，焊膏用量与焊盘尺寸按数据手册建议。
- ESD 防护：运输和贴装过程注意静电防护，晶振对静电敏感。
六、可靠性与存储
- 推荐长期储存于干燥、防潮环境，避免高温与强震动。
- 在关键设计中建议进行上板后老化测试与温度循环验证，以确保频率稳定性满足系统要求。
七、选型与采购建议
- 在最终选型前，请索取并核对厂方数据手册以确认封装图、焊盘尺寸、回流曲线及全部电气特性。
- 若对相位噪声、启动时间或更严格温漂有更高要求，可与厂家沟通或选择相邻等级产品。
- 卷带（T/R）包装方便批量生产，下单时注意最小起订量与交货周期。

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.
