CK1E220M-CRD54 产品概述
一、产品简介
CK1E220M-CRD54 为先科（ST）出品的贴片型铝电解电容，额定容量22µF，容差±20%，额定电压25V。器件为SMD封装，电容体直径5.0mm，长度5.4mm（D×L = 5×5.4mm），适用于对体积和高度有限制的表面贴装应用。
二、主要参数
- 容值：22µF（±20%）
- 额定电压：25V
- 尺寸：Φ5.0mm × 5.4mm（SMD）
- 工作温度：-40℃ ~ +105℃
- 寿命：2000 小时 @ 105℃
- 封装形式：贴片（SMD），品牌：ST（先科）
三、产品特点
- 体积小、容量相对较高，适合空间受限的电路板设计；
- 额定温度可达105℃，在高温环境下仍具有可靠的电性能；
- 适用于贴片回流工艺，便于自动化生产与高密度布局；
- 极性电容，需按电路极性正确安装；有关等效串联电阻（ESR）及纹波电流等更详细电参数，请参见厂商数据手册。
四、典型应用
- 开关电源的输出滤波与旁路；
- 模拟与数字电路的去耦、稳压模块；
- 工业控制、通信设备及便携电子产品的电源滤波与缓冲；
- 对寿命与高温性能有要求的嵌入式应用。
五、封装与安装建议
- 推荐采用标准SMD回流焊工艺，按照厂商回流曲线控制峰值温度与预热时间；
- 安装时注意极性标识，避免反向电压使用；
- 在布局时为散热和纹波电流预留合适空间，必要时并联多个电容以降低等效阻抗。
六、可靠性与使用注意
- 标称寿命2000小时@105℃，长期使用建议适当降额（如降低工作电压或温度）以延长寿命；
- 避免长时间超温、超压或反向电压，储存与使用环境应尽量干燥、避免剧烈振动；
- 详细的电气特性、回流曲线与焊接规范请参照ST（先科）提供的产品数据手册与可靠性报告。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
