RVE1E470M0605 产品概述
一、产品基本特性
RVE1E470M0605 是 ROQANG（容强）推出的一款贴片铝电解电容，主要参数如下：容值 47µF，公差 ±20%，额定电压 25V，纹波电流 170mA@120Hz，等效串联电阻（ESR）850mΩ。封装为 SMD，电容体直径 D=6.3mm，长度 L=5.4mm。工作温度范围 -55℃～+105℃，额定寿命 2000 小时（105℃）。
二、性能与特点
- 中等容量与中等电压等级，适合常见直流滤波与退耦应用。
- 纹波电流 170mA@120Hz，适用于中低频整流输出的滤波；需注意在高纹波环境下应评估温升与寿命影响。
- ESR 约 850mΩ，属于较高的 ESR 水平，对高频去耦或低阻抗输出可能不理想，但有利于减小回路振荡风险。
- 贴片封装（D6.3×L5.4mm）适合自动化贴装与空间受限的 PCB 布局。
三、应用场景
- 开关电源或线性电源的整流后滤波、输出端退耦与储能。
- 工业控制、仪器仪表、通信终端等需要稳定 DC 供电的场合。
- 低频耦合与旁路电路，或作为输入侧的大容量滤波元件。
注意：对要求极低 ESR 或高频纹波承受能力的电源（如高速开关电源输出端），应优先考虑低 ESR 或固态/钽电容配合使用。
四、选型与使用建议
- 极性提示：铝电解电容为极性元件，安装时必须正确识别正负极，避免反向电压导致失效或爆裂。
- 电压降额：为延长寿命与提高可靠性，建议在额定电压下留有余量（常见做法是取额定电压的 50%～80% 作为实际工作电压上限，视具体应用与温升而定）。
- 纹波与 ESR：若电路纹波电流接近或超过 170mA，应并联多只或改用额定纹波更高的型号；高频去耦应与低 ESR 的电容并联以获得更佳频率响应。
- 温度与寿命：标称寿命为 2000hrs@105℃，温度每降低一定幅度寿命显著延长。实际设计中应以目标环境温度、循环次数与允许失效率为依据进行寿命评估。
五、封装与可靠性
- 封装：SMD，电容体 D6.3×L5.4mm，适配常见的贴片工艺。
- 焊接与存放：建议遵循厂家推荐的回流焊曲线与湿敏等级要求，避免超温或长时间高温暴露。
- 可靠性测试：适用于一般工业等级产品的温度-寿命考核（2000hrs@105℃），并在合适的工作电压与环境条件下能提供稳定的滤波性能。
总结：RVE1E470M0605 是一款面向通用电源滤波与退耦的贴片铝电解电容，具有中等容量与电压等级、适合自动化贴装的紧凑封装。设计时应关注其 ESR 与纹波限制，并根据工作电压和温度做好降额与并联策略，以满足可靠性与寿命要求。若需更低 ESR 或更高纹波承受能力，建议结合其他电容类型或选用更高规格型号。

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.
