0122M4-25.000F12DWNL 产品概述
一、产品简介
0122M4-25.000F12DWNL 为杭晶（HCI）出品的全国产化贴片晶振，频率为 25.000 MHz。器件采用 SMD2520-4P 小型金属封装，结构稳固、焊接可靠，旨在为各种电子系统提供稳定、精确的时钟参考。常温频差±10 ppm，频率稳定度（全温区）±20 ppm，等效串联电阻（ESR）80 Ω，负载电容标称 12 pF，工作温度范围 -40 ℃ ~ +105 ℃，适合工业级环境下使用。
二、主要参数
- 品牌：HCI（杭晶）
- 型号：0122M4-25.000F12DWNL
- 类型：贴片晶振（晶体谐振器）
- 频率：25.000 MHz
- 常温频差（Initial）：±10 ppm
- 频率稳定度（-40~+105℃）：±20 ppm
- 负载电容：12 pF
- 等效串联电阻（ESR）：80 Ω
- 工作温度：-40 ℃ ~ +105 ℃
- 封装：SMD2520-4P（金属封装，4引脚）
三、产品特点与优势
- 国产化供应，便于生产与长期替代；品质和供货链可控。
- SMD2520 小尺寸金属封装，占板面积小，机械强度高，抗振性能好，适合自动贴装与回流焊工艺。
- 宽温工作范围及良好频率稳定性，能满足工业控制、通信和测试设备等对时间基准的严格要求。
- 标称 12 pF 负载电容，便于与主流 MCU/晶振电路配合使用；ESR 80 Ω，适配多数高增益晶体振荡器电路。
四、典型应用场景
- 通信与网络设备（包括以太网PHY等需 25 MHz 时钟的场合）
- 工业控制与自动化系统
- 测试与测量仪器、数据采集模块
- 消费电子及嵌入式系统的时钟源
五、使用与焊接建议
- 为保证标称负载电容 12 pF 的实际效果，建议在晶体两端各并接等值电容；由于 PCB 和引脚寄生电容存在，常用电容取值在 18~22 pF 范围以实现实际 CL≈12 pF。
- 电容应靠近 MCU/振荡器管脚放置，减少走线寄生和耦合噪声。
- 参考器件推荐的振荡电路（如 CMOS/CMOS-inverter 型振荡器），注意不要超驱动晶体，保证启动与稳定工作。
- 遵循一般回流焊工艺规范，避免过激的机械应力或弯折；焊接后建议进行必要的功能与频率验证。
六、可靠性与选型建议
- 在系统选型阶段，请结合目标电路的驱动能力与启动需求评估 ESR 与负载电容匹配；若对相位噪声或长期频率漂移有更高要求，可咨询厂家或选用更高等级的频率源（如温补或恒温晶振）。
- 对于需满足汽车功能安全或特定认证的项目，请与供应商确认器件是否具备相应资格与可靠性测试报告。
- 如需样品、详细封装/焊盘尺寸图或应用电路，建议联系杭晶（HCI）技术支持获取完整资料与建议。
此款晶振以小体积、国产化供应与工业级温度范围为优势，适合对 25 MHz 时钟有稳定性与长期供货要求的各类电子产品。

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.
