CS1C470M-CRD54 产品概述

一、产品概述

CS1C470M-CRD54 是 ROQANG(容强)出品的一款贴片型铝电解电容,额定容量 47 µF,公差 ±20%,额定电压 16 V。该器件采用 SMD 封装,电容体直径 D=5 mm,长度 L=5.4 mm(标识为 D5×L5.4mm),适用于对体积要求严格的表贴 PCB 设计。纹波电流规格为 31 mA @ 120 Hz,工作温度范围 -40 ℃ 至 +105 ℃,在 105 ℃ 环境下寿命为 1000 小时,适用于一般电子设备中要求中低纹波、低容量的去耦与滤波场合。

二、主要参数

  • 品牌:ROQANG(容强)
  • 型号:CS1C470M-CRD54
  • 容量:47 µF
  • 容差:±20%
  • 额定电压:16 V DC
  • 纹波电流:31 mA @ 120 Hz
  • 工作温度:-40 ℃ ~ +105 ℃
  • 工作寿命:1000 小时 @ 105 ℃
  • 封装:SMD,D5×L5.4 mm
  • 典型应用:电源去耦、滤波、旁路、稳压器输入/输出补偿等

三、主要特性与优势

  • 小型化封装:D5×L5.4 mm 的贴片体积非常紧凑,便于在空间受限的移动设备、消费电子和嵌入式模块中布置。
  • 中等容量、低外形:47 µF 在小体积下提供足够的储能,适合局部去耦和滤波用途。
  • 宽温域与高温寿命:-40~+105 ℃ 的工作温度范围与 105 ℃ 下 1000 小时的寿命,保证在高温工作环境下仍有一定可靠性。
  • 标准化电气规格:16 V 额定电压适配常见 3.3 V、5 V 电源系统(也可用于更高电压采配时的旁路/分压场合)。

四、典型应用场景

  • MCU、电源管理芯片和传感器等低功耗器件的局部去耦与稳定。
  • 线性稳压器的输入/输出滤波,减小低频纹波与突发电流尖峰(但受限于纹波电流能力)。
  • 消费电子、小型通信模块、物联网终端等对体积敏感的产品。
  • 不建议用于高纹波或大电流的开关电源主滤波(如高功率 DC-DC 输出)——此类场合需选择纹波电流和 ESR 更高、寿命更长的规格件。

五、可靠性与环境适应性

  • 该型号以短期高温寿命(1000 hrs @105 ℃)标称适应工业级工况,但在设计长期可靠性的产品时,应进行适当的电压与温度降额(derating)使用。
  • 在常温(例如 40~85 ℃)工作时,寿命会明显延长;在高温或高纹波应力下,寿命会相应缩短。
  • 由于铝电解电容本身受电解液与电极老化影响,建议在关键电源节点考虑冗余或选用更高寿命等级的器件。

六、封装与安装建议

  • 作为 SMD 元件,推荐采用标准回流焊工艺进行贴装;焊接工艺应遵循制造商的具体温度曲线,以避免封装或电解液受损。
  • 贴装时注意极性标识(铝电解电容为有极性元器件),负极方向必须正确。
  • PCB 布局建议将该电容尽量靠近被去耦的引脚或电源引出处,以减少引线电感和寄生阻抗带来的影响。
  • 对于需要更好热散或机械固定的设计,可在焊盘及周边采取适当的热沉或支撑结构。

七、选型与替代建议

  • 若目标电路存在较高纹波或较大充放电电流,应选用纹波电流更高、低 ESR 的铝电解或固态铝电解、电解陶瓷组合。
  • 对长期可靠性或高温寿命要求更高的场合,建议选用寿命更长(例如 2000h/3000h @105 ℃ 或 10000h @85 ℃)的型号。
  • 若空间允许,可通过并联多个更小阻抗的电容或与陶瓷电容并联来改善瞬态响应与等效串联电阻(ESR)特性。

八、储存、使用与注意事项

  • 存储应避免高温、高湿和阳光直射,并避免长时间在极端环境下储放。
  • 贴装与回流后应尽快投入使用以减少电解液挥发带来的性能下降。
  • 使用时注意电压极性、冲击电压限制与允许纹波电流范围,避免在超过规格条件下长期运行。

九、订购信息与备注

  • 型号:CS1C470M-CRD54(ROQANG / 容强)
  • 封装:SMD,D5×L5.4 mm;规格说明书与回流曲线建议向品牌技术支持或销售索取以确保生产工艺匹配。
  • 选型时请根据具体应用的纹波电流、寿命需求与工作温度进行评估,如有需要可联系供应商获取更详细的电气特性曲线(例如 ESR、耐压测试、容值随温度/频率的特性曲线)以保证设计可靠性。

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
