CS1C220M-CRC54 产品概述
一、概述
CS1C220M-CRC54 是 ROQANG（容强）生产的一款贴片型铝电解电容，标称容量 22µF，容差 ±20%，额定电压 16V。电容体外形为 SMD 贴片，尺寸 D4 × L5.4 mm，工作温度范围 -40℃ 至 +105℃，在 105℃ 下额定寿命 1000 小时。该型号在 120Hz 时的纹波电流为 20mA，适用于对中低频滤波与去耦有要求但纹波能量较小的应用场景。
二、主要电气与机械参数
- 容量：22µF ±20%
- 额定电压：16V DC
- 纹波电流：20mA @ 120Hz
- 工作温度：-40℃ ~ +105℃
- 寿命：1000 hrs @ 105℃
- 封装：SMD，电容体直径 4mm，长度 5.4mm（D4×L5.4mm）
- 品牌：ROQANG（容强）
此外，该类铝电解电容为有极性器件，PCB 布局时需明确正负极并保持极性标识清晰。
三、产品特点与应用建议
- 小体积贴片化设计，适合体积受限的消费电子和便携设备。
- 在低频（例如工频整流后的滤波）场合具有良好的电容储能能力；但纹波电流规格偏小，不适合承受大纹波或高频开关电源的主滤波器；若需处理高频纹波，建议与低ESR 陶瓷或钽电容并联配合使用。
- 建议在实际设计中对额定电压进行适度降额（例如不超过 75%~80% 的额定电压）以延长寿命与可靠性；在高温或连续大电流工作时应评估热管理。
四、封装与装配注意事项
- 作为 SMD 器件，支持回流焊装配；具体回流温度曲线及焊接工艺请参照厂方资料执行以避免过热导致性能退化。
- 存放与清洗：建议干燥保存，避免潮湿和腐蚀性气体环境；清洗时避免强溶剂浸泡极板端。
- PCB 布局：留足焊盘尺寸及热扩散空间，确保焊点可靠；注意极性标识并避免接反。
五、可靠性与选型提示
- 标称寿命 1000 小时（105℃）表示在高温高应力下的加速寿命测试结果，在正常工作温度下（例如 ≤85℃）寿命将显著延长。
- 若设计目标为长寿命或高可靠性（例如工业、通信设备），可选用额定寿命更长或纹波能力更高的规格产品，或并联多只电容以分担电流和降低等效 ESR。
- 在选型时综合考虑尺寸、容量、纹波电流与温度特性，CS1C220M-CRC54 适合中低功率、对体积敏感且要求中等寿命的滤波与去耦应用。

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.
