X1E0000210139 产品概述

一、产品简介

X1E0000210139 为 EPSON(爱普生)品牌的无源贴片晶振,封装为 SMD3225-4P(尺寸约 3.2 × 2.5 mm)。工作频率 25.000 MHz,常温频差 ±10 ppm,负载电容 12 pF,等效串联电阻(ESR)40 Ω,工作温度范围 -40 ℃ 至 +85 ℃。该器件为典型的表面贴装石英晶体,适用于对时钟精度要求中等偏高的数字系统时钟与高频参考。

二、主要技术参数

  • 类型:无源晶振(贴片,SMD3225-4P)
  • 频率:25.000 MHz
  • 常温频差:±10 ppm(室温标称)
  • 负载电容:12 pF
  • 等效串联电阻(ESR):40 Ω
  • 工作温度:-40 ℃ ~ +85 ℃
  • 品牌:EPSON(爱普生)

三、产品特点与优势

  • 封装紧凑,适配高密度 PCB 布局,体积小、重量轻;
  • 稳定性良好,常温频差 ±10 ppm 满足多数通信与处理器时钟需求;
  • 低至 40 Ω 的 ESR 有利于启动和稳定振荡,兼容多数 MCU/PLL 输入级;
  • 宽温范围适合工业级应用,可靠性和一致性高。

四、典型应用

  • MCU/MPU 时钟源(单片机实时时钟、主频参考);
  • 通信设备(PHY、收发器、模块参考时钟);
  • 消费类与工业电子(计量、测试设备、数据采集);
  • 网络与存储设备的本地振荡参考。

五、选型与电路注意事项

  • 负载电容选择:晶体标称 CL = 12 pF。实际需考虑电路板寄生电容(Cstray,通常 2–3 pF)并按公式 CL ≈ C/2 + Cstray 求对称电容 C。举例:若 Cstray = 3 pF,则 C ≈ 2×(12−3) = 18 pF,常采用 18 pF ~ 22 pF 的对称电容。
  • 驱动级匹配:确认 MCU/振荡器内部驱动能力与晶体 ESR 的匹配,ESR 偏大可能导致启动困难或振荡不稳定。
  • 无极性:晶体两端无极性,焊接时无需方向区分,但需按推荐焊盘布局安装。

六、PCB 布局与焊接建议

  • 将晶体与其负载电容尽量靠近 MCU 晶振输入脚放置,走短、对称的走线以减小寄生电感/电容;
  • 负载电容侧接地点要靠近电容脚做单点接地,避免地回路干扰;
  • 焊接采用回流工艺,遵循制造商推荐的回流温度曲线;通常请勿超过 260 ℃ 峰值温度并缩短高温停留时间以保证器件可靠性;
  • 气氛与再流次数按晶体制造规范控制,避免过多热循环。

七、储存与检验

  • 储存时避免潮湿、高温、强振动环境,未贴装器件建议保存在干燥箱中;
  • 来料检验可做外观、阻抗、启动测试与频率测试,确认常温频差与 ESR 满足规格要求。

八、订购与替代建议

  • 型号:X1E0000210139,品牌 EPSON,封装 SMD3225-4P。具体包装(卷带、数量)与交期请咨询供应商或经销商确认;
  • 替代选择时注意匹配频率、负载电容、ESR 与温度范围,若需更高精度可选择更严格频差或温度补偿晶体/谐振器。

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.

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
