CS1E220M-CRD54 产品概述
一、产品简介
CS1E220M-CRD54 为 ROQANG（容强）出品的高可靠性贴片铝电解电容，额定容量 22μF，额定电压 25V，允许容量偏差 ±20%。电容器采用 SMD 封装，电容体直径 5.0mm，长度 5.4mm（D5×L5.4mm），适用于对体积和高度有严格限制的电路板设计。典型应用包括电源滤波、去耦、退耦以及各类储能/旁路电路。
二、主要电气与机械参数
- 容值：22μF ±20%
- 额定电压：25V DC
- 纹波电流：25mA @ 120Hz
- 封装：SMD，尺寸 D5 × L5.4mm
- 工作温度范围：-40℃ ～ +105℃
- 使用寿命：2000小时 @ 105℃
- 极性：有极性（铝电解，安装时注意正负极）
三、产品特性与优势
- 小体积：5×5.4mm 的紧凑封装，适合空间受限的便携及嵌入式应用。
- 高温可靠性：2000 小时@105℃ 的使用寿命，适用于高温工作环境，满足一定的工业级要求。
- 宽温度范围：-40℃ 到 +105℃ 的工作温度，保证在严苛环境下的稳定性能。
- 成本效益：铝电解方案在相同性能下具有较好的性价比，适合中低频滤波与能量存储用途。
四、典型应用场景
- 开关电源与线性电源的输出滤波与稳压器退耦。
- 单板机、嵌入式控制器的去耦与电源旁路。
- 家用电器、照明驱动与消费类电子中对体积敏感的滤波场合。
- 低到中功率模拟电路的旁路与耦合（注意极性与纹波要求）。
五、设计与使用建议
- 额定电压留有裕度：为延长寿命并降低漏电及分解风险，建议实际工作电压不超过额定电压的 70%–80%，尤其在高温工况下。
- 极性注意：为铝电解电容，必须正确识别并遵循正负极安装，反向电压会导致损坏或爆裂。
- 温控管理：若电容工作在高温环境（靠近热源或高功率器件），建议采取散热或减少工作电压以延长寿命。
- 频率与纹波：所给纹波电流为 25mA @120Hz，若电路中存在较高频率纹波或脉冲电流，应评估 ESR 与温升情况，必要时选择更高纹波能力的型号或并联多只电容。
六、封装与可靠性
- 封装形式为 SMD 贴片，适合自动贴装与回流焊流程。具体回流焊温度曲线与包装形式（盘带/卷装）请参见容强官方数据手册。
- 可靠性指标包括 2000hrs@105℃ 的寿命测试，符合一般工业级使用要求。为满足更长寿命或高振动条件，请参考更高规格的电容系列。
七、选型与替代建议
- 若需更低 ESR、更高纹波能力或更长寿命，可考虑固态电解或钽电容以及低 ESR 铝电解型号；若空间允许，选择更大容量或更高额定电压的同系列产品以提升可靠性。
- 对于高频去耦场合，建议与多层陶瓷电容并联使用，以覆盖不同频段的滤波需求。

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.
