CS1A470M-CRC54 产品概述
一、产品简介
CS1A470M-CRC54 是 ROQANG（容强）推出的贴片型铝电解电容器，额定电容 47µF，额定电压 10V，容差 ±20%。器件为 SMD 封装，电容体尺寸 D4 × L5.4mm，适用于空间受限的表贴电路板，用于电源滤波、去耦与缓冲等场合。
二、主要参数
- 容值：47µF（±20%）
- 额定电压：10V
- 纹波电流：25mA @ 120Hz
- 外形尺寸：直径 4mm，长度 5.4mm（D4 × L5.4mm）
- 工作温度：-40℃ ～ +105℃
- 使用寿命：1000 小时 @ 105℃
- 封装：SMD（贴片型）
- 品牌：ROQANG（容强）
三、封装与极性提示
本系列为贴片铝电解，产品带极性标识（请严格区分正负极）。D4×L5.4mm 的紧凑体积适合高密度 PCB 布局。焊接时应遵循厂方的推荐回流曲线与焊盘布置，以保证焊点可靠性与电容性能稳定。
四、电气性能与适用场景
纹波电流规格为 25mA@120Hz，属于低至中等纹波能力，适用于滤除低频整流纹波、局部去耦与稳压器输出的辅助滤波。由于额定电压仅 10V，应优先用于低压电源轨（如 3.3V、5V 等）与便携设备的电源滤波场合。对需承受大纹波或高瞬态电流的电源回路，建议选用纹波能力更高的电容或并联多个器件分担电流。
五、可靠性与寿命管理
标准寿命为 1000 小时 @105℃，在低于额定温度的实际应用中寿命会显著延长。设计时建议对使用温度、直流偏压与纹波应力进行适当降额（derating），常见做法是额定电压取 60%~80%、工作温度尽量低于最高值并留有余量，以提升可靠性和寿命。
六、选型与使用建议
- 极性必须正确连接，反向电压会导致失效或爆裂。
- 对于有较高纹波或脉冲电流的场合，优先考虑纹波电流更高或使用固态/钽电容搭配。
- 焊接按推荐回流曲线进行，避免长时高温或重复热循环。必要时，贴片前进行烘烤以去除吸湿。
- 在机械振动或冲击较大的环境，关注焊点与封装应力，必要时采取固定或缓冲措施。
七、典型应用
便携设备电源滤波、微控制器与模拟电路的去耦、背光/显示驱动辅助电源、板载储能与旁路等低压低功耗电子产品。
八、包装与采购
CS1A470M-CRC54 常见为贴片盘带（Tape & Reel）供货，具体包装规格与最小订购量请联系 ROQANG 或授权分销商确认。订购时请注明型号全称与生产批号以便获得一致性的质量保证。
总结：CS1A470M-CRC54 以小体积、适中的电容值和工作温度特性，适合低压、空间受限的电源滤波与去耦场合。选型时应重点考虑纹波电流与工作温度对寿命的影响，必要时通过并联或更高规格器件来满足更苛刻的电流与寿命要求。

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.
