CS1V220M-CRD54 产品概述

CS1V220M-CRD54 是 ROQANG(容强)出品的一款小型贴片铝电解电容,额定容量 22 μF,额定电压 35 V,封装为 SMD(D5×L5.4 mm)。该器件面向体积受限的电子设备电源滤波与去耦场合,结合耐高温设计与标准化封装,适合批量贴装与自动化生产。

一、主要参数一览

  • 容值:22 μF
  • 精度:±20%
  • 额定电压:35 V
  • 纹波电流:28 mA @ 120 Hz
  • 封装尺寸:直径 5.0 mm × 长度 5.4 mm(SMD)
  • 工作温度范围:-40 ℃ ~ +105 ℃
  • 工作寿命:1000 小时 @ 105 ℃
  • 形式:贴片(表面贴装)铝电解电容
  • 品牌:ROQANG(容强)

二、产品特性与优势

  • 小型化封装:D5×L5.4mm 的圆柱体封装适合对高度和占板面积有严格要求的应用,便于在多层板和紧凑型电源模块中使用。
  • 高温适应性:额定工作温度上限 105 ℃,可在高温工作环境下短期使用,且在制造和测试过程中具有更宽裕的热余量。
  • 自动化贴装友好:SMD 封装适配常见回流焊工艺与贴片机,利于自动化生产线的高速贴装与焊接。
  • 标准化电气特性:22 μF/35 V 的规格满足多数中低功率开关电源、线性稳压后端滤波和直流链路储能的需求。

三、典型应用场景

  • 开关电源输出滤波与补偿:用于 SMPS 输出端的滤波、降低纹波电压与稳定环路。
  • 稳压/线性电源的平滑电容:在线性稳压器或参考电路中用于初级纹波去除与旁路。
  • 模拟及音频前端去耦:在模拟放大器或音频电路中改善电源稳定性与抑制低频噪声(注意极性与纹波要求)。
  • 工业与通信设备的散装模块:适合体积受限的控制板、通信模块和嵌入式设备电源设计。

四、设计与使用建议

  • 极性识别与连接:作为铝电解电容,CS1V220M-CRD54 为极性器件,正负极必须按电路设计正确接入,避免反接或在电路中承受反向电压。
  • 布局与走线:为降低有效等效串联电阻(ESR)和等效串联电感(ESL),应尽量将电容放置在被去耦器件或电源输出端的近旁,走线最短、焊盘面积合理且接地回流路径宽阔。
  • 纹波电流注意:标称纹波电流为 28 mA@120 Hz,属于较小值,适用于中低纹波工作点;在高频开关电源场合,需评估电容在高频纹波下的发热与寿命影响,必要时并联低 ESR 的陶瓷电容以分担高频成分。
  • 电压与温度降额:为延长寿命与可靠性,建议在高温长期工作时对额定电压进行降额使用(根据具体使用工况和可靠度要求制定),避免长时间满压满温运行。

五、可靠性与焊接注意

  • 寿命说明:标称寿命为 1000 小时 @ 105 ℃,该寿命指标用于规格化比较和高温短期评估;长期应用或高可靠场合应选用寿命更高的型号或考虑更低的实际运行温度。
  • 回流焊兼容性:SMD 类铝电解电容需按厂家推荐的回流焊温度曲线进行焊接。过高的回流峰值温度或超时可能影响电容内部电解液和密封性能,建议参考容强提供的焊接工艺文件。
  • 存储与处理:避免潮湿环境长期存放,存放前保持原包装密封;贴装前若已超过厂家建议的保质期或暴露于高湿环境,需按照厂家说明进行回流前烘烤处理(若适用)。

六、选型与替代建议

  • 若电路存在较大纹波电流或高频分量,建议并联低 ESR 陶瓷电容以分流高频纹波,或选用标称纹波电流更高的铝电解/铝聚合物电容。
  • 对于对寿命要求更高或长期 105 ℃ 下运行的应用,可考虑寿命等级更高(如 2000h、3000h 或更长寿命)的产品系列。
  • 若对体积和 ESR 有更严格要求,可评估铝聚合物电容或固态电容作为替代,但需综合考虑成本与极性特性。

如需完整电气参数、典型曲线、回流焊工艺与可靠性试验数据,请索取 ROQANG(容强)官方数据手册(Datasheet)和样片以便在实际设计中进行验证与可靠性评估。

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
