CS1H470M-CRE77 产品概述

一、产品简介

CS1H470M-CRE77 是 ROQANG(容强)推出的一款贴片型铝电解电容器,额定容量 47µF,额定电压 50V,容差 ±20%。本元器件采用 SMD 封装,电容体直径 φ6.3mm,长度 7.7mm,设计用于要求高密度贴装与中高电压滤波的电子电路,适合工业、通信、电源模块等多种场景。

二、主要参数

  • 容值:47µF ±20%
  • 额定电压:50V
  • 纹波电流:63mA @ 120Hz
  • 电容体尺寸:D6.3 × L7.7 mm(SMD)
  • 工作温度:-40℃ ~ +105℃
  • 工作寿命:1000 小时 @ 105℃
  • 封装与品牌:SMD,ROQANG(容强)

三、产品特点

  • 小体积高电压:D6.3×L7.7mm 的紧凑封装,在 50V 电压等级下实现 47µF 的电容量,有利于电路板空间受限时的电源去耦与滤波设计。
  • 可靠性与耐热性:额定寿命 1000 小时(105℃),适合中等温度与中短期高应力环境。
  • 标准化 SMD 安装:适配自动贴装和回流焊工艺,提升生产效率与可靠性。
  • 可满足低频纹波滤波:63mA@120Hz 的纹波电流性能,适用于线性电源输出及低频整流滤波场合。

四、典型应用场景

  • 开关电源辅助滤波与输出电解滤波
  • 工业控制电源、单板供电去耦
  • 通信设备的中低频滤波与旁路
  • 仪器仪表、电池管理系统等需中高压容量的场合

五、使用与设计注意事项

  • 电压与温度降额:为延长寿命与提高可靠性,建议在高温或长寿命要求下对额定电压与工作温度进行降额设计,并为纹波电流留有裕量。
  • 散热与布局:纹波損耗会转化为热量,应在 PCB 布局上考虑散热路径,避免元件周围热源集中。必要时增大铜箔面积或增加热沉。
  • 回流焊工艺:采用标准回流焊流程并遵循厂方推荐的焊接曲线(符合 IPC/JEDEC 标准),以防止焊接热应力损伤电容。
  • 极性与旁路:铝电解电容为极性器件,安装时注意极性标识;用于高频旁路时宜与陶瓷电容并联以改善高频性能。

六、可靠性与寿命管理

  • 额定寿命为 1000 小时 @ 105℃,在实际应用中寿命会随温度、纹波电流和工作电压的变化而显著变化。降额运行与良好散热可显著延长使用寿命。
  • 长期运行中容量衰减、等效串联电阻(ESR)上升和泄漏电流增加是主要老化表现,应在系统设计中预留裕度并制定相应的维护或更换周期。

七、封装与安装建议

  • 封装:SMD(φ6.3×L7.7mm),适用于自动贴装机与回流焊流程。
  • 焊盘设计:参考制造商推荐的焊盘尺寸与阻焊开口,保证焊点可靠性与散热效果。
  • 存储与搬运:避免高温、高湿与强振动环境,防止机械挤压或跌落导致密封件损伤。

八、选型与替代建议

CS1H470M-CRE77 适用于需在有限空间内实现 50V 等级滤波的场合。选型时应综合考虑容量、纹波电流、工作温度与寿命要求;如需更高纹波承载或更长寿命,可选用额定纹波更高或寿命更长(如 2000~5000 小时)系列的铝电解电容,或在并联多只器件以分担纹波与降低 ESR。

如需详细电气特性图、电容随温度/频率特性、推荐焊盘或回流曲线,请提供进一步需求或联系 ROQANG 官方数据资料,以获得完整的工艺和应用规范。

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.

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
