EEFGX0E471R 产品概述
一、产品简介
EEFGX0E471R 是松下（PANASONIC）推出的一款高性能聚合物固态电容，额定电压为 2.5V，标称电容值 470µF，容差 ±20%。该器件为 SMD 封装，体积小（7.3 × 4.3 mm），专为高频、大电流纹波抑制和严格空间约束的电源滤波场合设计。
二、主要性能特点
- 聚合物固态结构，提供稳定的温度和频率特性；
- 纹波电流能力高：10.2 A @ 100 kHz，适合大电流高速开关环境；
- 低等效串联电阻（ESR）：3 mΩ @ 100 kHz，有利于降低功率损耗与发热；
- 宽工作温度范围：-55 ℃ ～ +105 ℃，在高温条件下仍可可靠工作；
- 工作寿命：2000 小时 @ 105 ℃，适合长期运行的电源模块。
三、典型应用场景
适用于各类需要高频滤波和大纹波承受能力的场合，例如：
- DC-DC 降压/升压转换器的输出侧滤波与去耦；
- 电源管理模块（VRM、PMIC）和负载旁滤波；
- 通信设备、电源模块、便携式终端与工业电子中对体积及性能有较高要求的电路。
四、关键技术规格（摘要）
- 容量：470 µF ±20%
- 额定电压：2.5 V
- 纹波电流：10.2 A @ 100 kHz
- ESR：3 mΩ @ 100 kHz
- 类型：聚合物固态电容（固态电解质）
- 封装尺寸：SMD，外形 7.3 mm × 4.3 mm
- 工作温度：-55 ℃ ～ +105 ℃
- 工作寿命：2000 小时 @ 105 ℃
五、封装与机械特性
器件为表面贴装封装，体积紧凑，适合高密度 PCB 布局。7.3×4.3mm 的外形在空间受限的电源模块或模块化电源设计中具有明显优势。建议按照厂商推荐的焊接与贴装工艺进行装配，以确保焊点可靠性与电容性能。
六、选型与使用建议
- 电压及温度裕量：尽量在额定电压及温度下留有裕量，避免长期满额定条件运行可延长寿命；关注工作温度对电容容量和 ESR 的影响；
- 并联与热分散：在需更低 ESR 或更高纹波能力时，可考虑并联多只电容；并联布局应注意热管理与等效电流分配；
- 布局注意：靠近受扰电路或功率器件布置以优化去耦效果，缩短引线长度以降低寄生电感；
- 测试与验证：在目标应用中进行热仿真与长期寿命验证，确认在实际工况下的可靠性。
七、注意事项
- 切勿超过额定电压与最大工作温度以避免性能退化或寿命缩短；
- 遵循制造商的焊接曲线与储存规范，防止因回流焊、潮湿或机械应力导致故障；
- 如需在特殊环境（如高湿、高振动或汽车级）使用，请与供应商确认额外可靠性与认证要求。
该产品以其高纹波承受、超低 ESR 和小型封装，适合对电源性能与体积均有较高要求的现代电子设备电源设计。若需更详细的电气曲线、回流焊工艺或可靠性认证资料，建议参考松下官方规格书或联系供应商获取原厂文件。

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.
