CS1A471M-CRE77 产品概述
一、产品简介
CS1A471M-CRE77 是 ROQANG（容强）推出的一款贴片型铝电解电容，标称容量 470µF，额定电压 10V，容差 ±20%。电容体尺寸为 D6.3 × L7.7mm，适用于对体积和容量有严格限制的表面贴装电路。该型号为高温系列，工作温度范围为 -40℃ 至 +105℃，在 105℃ 下额定寿命为 1000 小时，能满足中高温环境下的可靠供电与旁路滤波需求。
二、主要技术参数
- 容值：470µF，精度 ±20%
- 额定电压：10V
- 纹波电流：120mA @ 120Hz
- 电容体尺寸：直径 6.3mm，长度 7.7mm（SMD 封装）
- 工作温度：-40℃ ~ +105℃
- 工作寿命：1000 hrs @ 105℃
- 品牌：ROQANG（容强）
三、产品特性与优势
- 小型化高容量：6.3×7.7mm 的紧凑外形，在体积受限的板级设计中仍能提供 470µF 的大容量储能。
- 耐高温长期可靠：105℃、1000 小时的寿命等级适用于汽车电子、工业控制等高温工况或近热源布置的场合。
- 良好滤波性能：针对低频纹波（120Hz）具有明确的纹波电流额定值，适合开关电源输出和整流后滤波。
- SMD 装配友好：贴片封装便于自动化贴装和大规模生产，提高装配一致性和产线效率。
四、典型应用场景
- 开关电源（DC-DC）输出端或输入端的旁路与储能。
- 工业控制与嵌入式系统的去耦与滤波。
- 便携式设备、通信设备中对体积与能量密度有要求的电源模块。
- 近热源或高温工作环境下的电源回路。
五、使用与设计建议
- 建议在可接受范围内进行电压去额定（如优先考虑低于额定电压运行），以延长寿命与降低漏电流增长。
- 布局时应尽量缩短电容与被滤波器件之间的连接距离，减小等效串联阻抗（ESR）对性能的影响。
- 回流焊及温度应遵循厂方推荐工艺；如无具体曲线，建议采用常规 SMD 焊接注意降低峰值温度和热暴露时间。
- 在高温或高纹波工况下，需考虑并联多个电容或选择更高纹波容限的型号以满足可靠性要求。
六、可靠性与包装提示
CS1A471M-CRE77 具有明确的高温寿命等级，适合长期稳定运行的工业应用。为保证性能，建议在干燥、常温环境中存放，并按厂方建议的出厂寿命和回流焊工艺使用。具体电气参数（如 ESR、泄漏电流、回流曲线、推荐焊盘等）请参考产品详细数据表或联系厂方技术支持获取完整资料。

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.
