EEEFP1E471AP 产品概述
一、产品简介
EEEFP1E471AP 是松下（PANASONIC）生产的一款贴片型铝电解电容，额定电容为 470µF，公差 ±20%，额定电压 25V。外形为 SMD 圆柱体，电容体直径 10mm，长度 10.2mm（D10×L10.2mm），适用于体积受限的高密度应用场合。
二、主要电气参数
- 容值：470µF ±20%
- 额定电压：25V
- 纹波电流：1.19A（@100kHz）
- 等效串联电阻（ESR）：60mΩ（@100kHz）
- 工作温度范围：-55℃ ~ +105℃
- 额定寿命：2000 小时（@105℃）
以上参数表明该器件在高频开关电源和稳压滤波等场合具有良好的纹波抑制能力与中等 ESR 表现。
三、结构与性能特点
该型号为铝电解工艺，具有高容值体积比优势，ESR 在 100kHz 时为 60mΩ，配合 1.19A 的纹波电流能力，适合用于中等功率密度的电源滤波与去耦。工作温度上限 105℃ 与 2000 小时寿命规格，表明其在高温应用下仍能保持稳定性能（但需遵循寿命衰减规律与降额使用）。
四、典型应用场景
- 开关电源输入/输出滤波与能量储存
- DC-DC 转换器旁路与去耦
- 工业电源、通信设备及部分车规电子（视系统环境与认证要求）
- 对体积敏感的消费类电子设备电源模组
五、选型与使用建议
- 工作电压建议留有裕量，尽量以额定电压的 60%~80% 作为长期工作电压以延长寿命。
- 注意纹波电流与 ESR 导致的自热，确保实际工作情况下温升不会超过器件额定温度。
- 极性敏感，贴片安装时保证正负极方向正确并避免反向电压。
- 在高振幅交流或大纹波环境中考虑并联低 ESR 电容或增加散热措施。
六、焊接、储存与可靠性注意事项
- 按照厂家推荐的回流焊温度曲线进行贴装，避免过高的峰值温度及长时间高温暴露以减少电解质老化。
- 存储时避免潮湿、高温和强振动；长时间存放建议进行预老化或电压恢复测试。
- 2000 小时@105℃是加速寿命参考值，实际使用寿命将随温度、纹波、电压应力和环境条件变化，应据具体应用进行可靠性评估。
七、小结
EEEFP1E471AP 以 470µF/25V 的容量、较低 ESR 与良好的纹波电流能力，在小体积 SMD 电源滤波与去耦应用中具有竞争力。设计时应重视降额使用和热管理，以确保长期可靠性与稳定性能。若需更高寿命或更低 ESR 的替代方案，可考虑固体电解或聚合物电容，根据系统需求权衡选型。

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.
