CS2A220M-CRF10 产品概述
一、产品简介
CS2A220M-CRF10 为贴片型铝电解电容，标称容量 22µF，额定电压 100V，容值公差 ±20%。电容体尺寸为 D8 × L10.5mm，封装形式为 SMD（贴片）。工作温度范围 -40℃ ～ +105℃，在 105℃ 条件下的典型寿命为 2000 小时。品牌：ST（先科），适用于需要高耐压、小体积滤波与能量缓冲的电子系统。
二、主要特性
- 高额定电压：100V，适合中高压直流滤波与隔直流耦合场合。
- 紧凑尺寸：8mm 直径、10.5mm 长度，节省 PCB 面积，适合密集布板。
- 温度与寿命：-40℃～+105℃ 工作温度，2000hrs@105℃ 的设计寿命，适用于工业级环境。
- 常用封装：SMD 形式便于自动贴装与回流工艺，提高生产效率。
三、应用场景
- 开关电源与DC-DC 转换器的输入/输出滤波。
- 中小功率逆变器、驱动与伺服电源的缓冲与去耦。
- 工业控制、电源管理与测试设备中需承受较高直流电压的滤波回路。
- 其他对体积和耐压有要求的电子产品中用作耦合或旁路电容。
四、使用与设计建议
- 极性注意：铝电解电容为极性元件，使用时注意正负极安装方向。
- 电压降额：为延长寿命，建议在实际应用中对额定电压进行适当降额设计（建议参照 50%～80% 范围并结合实际工况评估）。
- 温度管理：减少工作温度和纹波电流可显著延长使用寿命，布板时注意热源隔离与散热路径。
- 回流与焊接：采用标准回流焊工艺时，请遵循厂家推荐的温度曲线和预热/冷却要求，避免长时间高温暴露及急冷急热。
五、存储与可靠性
- 存放于干燥、常温环境，避免潮湿与强光直射；长期储存前请按供应商要求进行封装完整性检查。
- 在高温高纹波工况下寿命会缩短，建议在设计阶段予以留裕并做好寿命验证。
六、包装与采购
CS2A220M-CRF10 为 SMD 贴装产品，通常以卷带（Tape & Reel）形式供货（具体包装方式请向供应商确认）。订购时请注明完整型号、批次及需要的包装方式，以便获取准确的出货与品质追踪信息。
如需样品测试、电气特性表（如等效串联电阻 ESR、纹波电流等）或更详细的回流与可靠性数据，请提供采购需求或联系先科（ST）技术支持获取最新数据表。

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.
