CS1E471M-CRG10 产品概述
一、产品简介
CS1E471M-CRG10 为先科（ST）推出的贴片型铝电解电容，额定电压25V，标称电容470μF，容差±20%。电容体尺寸为直径10mm、长度10.5mm，SMD封装，适用于对体积有较高要求但需较大容值的表面贴装电路。工作温度范围为-40℃至+105℃，在105℃下额定寿命为2000小时，属高温短寿命级别的铝电解产品，适合工业级电源滤波与储能用途。
二、主要参数
- 品牌：ST（先科）
- 型号：CS1E471M-CRG10
- 容值：470μF
- 容差：±20%
- 额定电压：25V
- 封装：SMD，电容体 D10 × L10.5 mm
- 工作温度：-40℃ ~ +105℃
- 额定寿命：2000 hrs @ 105℃
三、性能与优势
- 大容值与小体积：在直径10mm的贴片封装中提供470μF，便于在受限空间内实现能量储备与滤波。
- 宽工作温度：-40℃至+105℃，适应范围覆盖多数工业电子应用。
- SMD工艺兼容：便于自动化贴装与回流焊接，提高装配效率。
四、典型应用场景
- 开关电源与稳压模块的输入/输出滤波与缓冲。
- DC-DC转换器的储能与瞬态响应改善。
- 工业控制、电源模块、通信设备及消费电子中需要中大容量滤波的场合。
五、选型与使用建议
- 极性注意：铝电解电容为有极性器件，请确保正确接线，避免反向电压。
- 电压降额：为延长寿命，建议在实际工作中对额定电压进行降额使用（常见做法为不超过额定电压的80%–90%）。
- 温升与散热：高温环境或附近热源会加速老化，应改善散热与布局以降低工作温度。
- 寿命估算：经验上每降低10℃寿命约加倍，举例在85℃下的预计寿命可明显长于在105℃下的2000小时，但实际寿命受电压、纹波电流等因素影响，需按应用条件评估。
六、封装与安装注意事项
- 使用前请参照先科提供的回流焊工艺规范，避免超出推荐的温度曲线。
- PCB布局应预留合适焊盘和固定胶点，必要时在震动环境中对元件进行加固。
- 元件顶端有安全泄气结构，焊接后应保证泄气方向不受阻挡，避免在封装或覆盖物下方安装。
- 清洗与储存：遵循厂商对清洗剂和储存条件的建议，长期存放后若有必要可进行电容化成处理。
七、可靠性说明
该产品在105℃下的额定寿命为2000小时，适用于要求短期高温运行或经过热管理设计的系统。实际可靠性与寿命受工作电压、纹波电流、环境温度及热循环影响，建议在关键应用场合进行样机验证并与供应商确认详细技术条件与测试报告。
如需完整的电气特性曲线（ESR、漏电流、纹波电流等）、回流焊曲线或产品认证资料，可向先科（ST）索取数据手册与可靠性测试报告。

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.
