RVE1C470M0505 产品概述
一、产品简介
RVE1C470M0505 为 ROQANG（容强）生产的一款贴片铝电解电容，额定电容值 47µF ±20%，额定电压 16V，紧凑 SMD 封装（D5×L5.4mm）。该器件针对空间受限的移动、电源与消费电子应用开发，兼顾小体积与中等纹波承受能力，适合做滤波、去耦和储能用途。
二、主要技术参数
- 容值：47µF ±20%
- 额定电压：16V
- 纹波电流：110mA @ 120Hz
- 等效串联电阻（ESR）：1.5Ω
- 机械尺寸：直径 5.0mm，长度 5.4mm（D5×L5.4mm）
- 封装：SMD（贴片）
- 工作温度：-55℃ ~ +105℃
- 工作寿命：2000 hrs @ 105℃
三、电气性能与使用建议
该电容 ESR 较高（1.5Ω），适用于低频滤波及一般去耦场合；在高纹波或高频旁路应用中需注意温升与寿命下降。设计时建议：
- 考虑电压与温度降额（常用经验值为额定电压的50%–80%），以延长寿命；
- 确认实际工作纹波不超过标称 110mA（120Hz），并预留裕量；
- 对于对 ESR 敏感的电路，可并联低 ESR 电容以改善瞬态性能。
四、机械与封装说明
小尺寸圆柱形电容，适合自动贴装。封装型号标识为 D5×L5.4mm，安装时请预留足够环氧与焊盘面积以保障焊点可靠性；注意元件顶部安全阀方向及极性标识，避免反向焊接。
五、可靠性与寿命
额定寿命为 2000 小时（105℃），在较低温度下寿命会显著延长。长期可靠性与实际寿命受工作温度、纹波电流及电压应力影响较大，建议参考厂商寿命曲线并在设计中实施降额策略。
六、典型应用场景
适用于电源滤波、整流后滤波、低频去耦、模拟电路耦合/旁路、小型 DC-DC 输出端滤波等对体积有要求且纹波不高的场合。
七、焊接与存储注意事项
- 推荐遵循 J-STD-020 回流曲线，峰值温度≤260℃，液相时间尽量短于 10s；
- 储存避免潮湿、高温及机械应力，贴片后应及时回流以减少氧化；
- 安装时确认极性，避免反向电压造成可靠性问题。
总结：RVE1C470M0505 以小体积、标准电气特性和适中的纹波能力，适合空间受限且对高频低 ESR 要求不是很苛刻的滤波和去耦应用。设计时应重视电压/温度降额与纹波限制，以确保长期可靠性。

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.
