CS1E471M-CRG10 产品概述
一、产品简介
CS1E471M-CRG10 是 ROQANG（容强）推出的一款贴片型铝电解电容，额定容量 470µF，额定电压 25V，适用于对体积、容量和耐热性有要求的 SMD 电源旁路与滤波场合。电容体尺寸为直径 D10mm × 长度 L10.5mm，便于在中小型电源模块和功率板上布局。
二、主要参数
- 容值：470µF
- 容差：±20%
- 额定电压：25V
- 纹波电流：270mA @ 120Hz
- 尺寸（电容体）：D10 × L10.5 mm（SMD）
- 工作温度：-40℃ ～ +105℃
- 工作寿命：2000 小时 @ 105℃
- 品牌：ROQANG（容强）
- 型号：CS1E471M-CRG10
三、关键特性与优势
- 大容量/紧凑体积：470µF 在 D10×L10.5 的小封装内实现，适合空间受限却需较高滤波能力的设计。
- 高频纹波承受能力：标称 270mA@120Hz 纹波电流，适用于中等负载纹波抑制。
- 高温耐久：2000 小时 @105℃ 的寿命指标，适合较苛刻的工业级或车规邻近温度环境（需按系统热设计评估）。
- 容差 ±20%，在电源滤波与功率缓冲应用中具有成本效益。
四、典型应用场景
- 开关电源输出滤波与退耦
- DC-DC 转换器输入/输出滤波
- 工业控制、电源模块与通信设备的电容储能与纹波抑制
- 对空间和焊装工艺有要求的表面贴装设计
五、选型与使用建议
- 额定电压选型上建议留有裕度，常见做法是按实际工作电压选择额定电压的 1.2～2 倍余量以提高可靠性。
- 纹波电流：应将实际电路中的纹波电流与本件额定值比较，必要时并联同型号或提高尺寸以满足散热与寿命要求。
- 使用温度与寿命：在低于 105℃ 的实际工作环境中寿命可显著延长，设计时请参考厂方寿命曲线。
- 若需更低等效串联电阻（ESR）或更高纹波处理能力，请参考厂家完整技术手册或选择专用低 ESR 系列。
六、封装与可靠性
- 封装为 SMD（贴片）形式，电容体尺寸 D10×L10.5mm，适用于回流焊工艺；具体回流曲线与焊接参数请遵循厂家推荐以避免性能退化。
- 极性器件，安装时注意正负极标识，反向连接会导致性能损坏甚至爆裂。
七、注意事项与维护
- 存储时避免潮湿、高温和强酸碱环境，焊接前若包装打开请按吸湿规定处理。
- 若需替换或并联使用，请保持相同或兼容的额定电压与温度等级，并尽量匹配容量与 ESR 性能。
- 详细电气特性（如 ESR/ESL 随频率变化曲线、耐压测试、漏电流等）建议参阅 ROQANG 官方数据手册或向销售工程师索取完整样本页。

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.
