CS1C470M-CRE54 产品概述

CS1C470M-CRE54 是先科(ST)系列的贴片型铝电解电容器,额定容量 47µF,额定电压 16V,容值允许偏差 ±20%。该器件采用小尺寸 SMD 封装(直径 D 6.3mm × 长度 L 5.4mm),额定工作温度范围宽(-40℃ 至 +105℃),并具有 1000 小时 @ 105℃ 的额定寿命,适用于空间受限但对性能与可靠性有要求的电源滤波、去耦与储能场景。

一、主要参数一览

  • 型号:CS1C470M-CRE54
  • 品牌:ST(先科)
  • 电容值:47 µF
  • 容差:±20%
  • 额定电压:16 V
  • 温度范围:-40℃ ~ +105℃
  • 额定寿命:1000 hrs @ 105℃
  • 封装形式:SMD(贴片)
  • 尺寸:直径 6.3 mm × 长度 5.4 mm

二、关键特性

  • 小体积高密度:D6.3×L5.4 的紧凑封装适合高密度贴装的移动设备和便携式电子产品,节省 PCB 面积。
  • 高工作温度:最高工作温度可达 +105℃,并在该温度下具有 1000 小时的寿命等级,适合轻工业级及要求中高温可靠性的应用。
  • 宽温度范围:-40℃ 至 +105℃ 的工作温度覆盖了多数消费电子与部分工业应用场景。
  • SMD 安装:贴片结构利于自动化贴装与回流焊工艺,提高生产效率和一致性。
  • 电气适用性:47µF/16V 的规格对各类 5V/12V 系统的去耦、纹波抑制与局部储能均具备良好适配性。

三、性能与可靠性说明

  • 寿命等级:额定寿命为 1000 小时 @105℃,在此条件下电容器应维持其基本电性能。实际寿命会随工作温度、电压和纹波电流的不同而变化。
  • 耐热耐候:器件设计用于较高温度工作环境,适合热量集中的电源模块或靠近热源的电路区域。
  • 漏电与失效模式:铝电解电容在高温或过压下可能出现容量衰减与漏电流上升,建议依据使用环境进行适当的电压与温度管理。
  • 建议降额使用:为延长使用寿命并提高系统可靠性,建议在长期运行情况下对工作电压进行适当降额(例如低于额定电压)并控制结温。

四、典型应用场景

  • 开关电源输出滤波与输入缓冲
  • DC-DC 转换器的输入/输出去耦
  • 音频放大电路的电源旁路与耦合(需按电路要求匹配)
  • 手机、便携式设备、机顶盒与家庭网关等消费电子产品
  • 工业控制模块中靠近电源的滤波与能量储存

五、封装与焊接建议

  • 裸片尺寸:D6.3×L5.4mm,适配常见 SMD 自动贴装设备。
  • 回流焊:建议遵循厂商给出的回流焊曲线与预热/峰值温度限制,避免反复多次高温回流。若生产流程中存在多次返修回流,应与供应商确认可靠性影响并考虑局部保护措施。
  • 存储与预处理:若元件在潮湿环境中长期存放,组件可能需要烘烤以去除吸潮,避免焊接过程中产生内部气泡或电性能异常。具体烘烤条件请参照供应商说明。
  • PCB 布局:安放位置应兼顾热源分布与电源路径最短原则,尽量缩短关键去耦电容与电源芯片之间的走线,以降低寄生电感与噪声。

六、选型与使用注意事项

  • 环境匹配:若设备在高温连续工作或高纹波电流下使用,应评估是否需要更高寿命等级(如 2000~5000 小时 @105℃)或选用更大容量/更高电压余量的型号。
  • 容差与容量裕度:±20% 的容差在大多数电源去耦场合是可接受的,但在对容量精度敏感的滤波场合,请考虑并联/串联或选择更高精度器件。
  • 替代与兼容:在需替换或改型时,注意与原器件在尺寸、引脚布局、寿命等级、电气参数(容量、耐压、ESR/ESL)方面的一致性。若需严格的低 ESR 或高频特性,请参考供应商提供的相关电气参数或选择专用低 ESR 器件。

七、采购与支持

  • 型号:CS1C470M-CRE54,品牌先科(ST)。
  • 若需批量采购、样品测试或获取更详细的电气特性(如 ESR、容抗、额定纹波电流、等效电路模型及回流焊曲线),建议联系先科或其授权分销商索取完整规格书与可靠性测试报告,以确保在目标应用中的表现符合预期。

如需我帮您整理此型号的典型 PCB 封装建议、推荐替代型号对比(含更高寿命或更低 ESR 的选项),或依据具体电路计算建议使用数量与布局,请提供电路工作电压、峰值纹波与空间限制等信息。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
