CS1E220M-CRD54 — 贴片铝电解电容产品概述

一、产品简介

CS1E220M-CRD54 为 ST(先科)品牌的贴片型铝电解电容,公称容量为 22 µF,公差 ±20%,额定电压 25 V。外形为 SMD 封装,电容体直径 5 mm,长度 5.4 mm(D5×L5.4mm),适合对体积有较高要求的表面贴装电路板(SMT)应用。该型号设计用于在较高温度和较严苛工作环境下提供稳定的滤波与去耦性能,工作温度范围为 -40 ℃ 至 +105 ℃,并能在 105 ℃ 下持续工作 1000 小时。

二、主要性能与参数

  • 容量:22 µF
  • 容量公差:±20%
  • 额定电压:25 V DC
  • 封装:SMD,电容体尺寸 D5 × L5.4 mm
  • 工作温度:-40 ℃ ~ +105 ℃
  • 额定寿命:1000 小时 @ 105 ℃
  • 类型:铝电解电容(贴片)
  • 品牌:ST(先科)

注:电容的等效串联电阻(ESR)、纹波电流等电气参数请以厂商数据手册为准,选型时建议参照完整规格书。

三、典型应用场景

  • 电源去耦与滤波:用于稳压器输出侧或分配电源的局部去耦,平滑电压波动与降低噪声。
  • DC-DC 转换器输出电容:适用于中小功率转换器的输出滤波。
  • 信号耦合/旁路:在对容量需求在十几微法范围且空间受限的电路中使用。
  • 工业与通讯设备:适应较宽温度范围与较长工作寿命,适用于工业级电子模块与通讯基站等。

四、焊接与使用建议

  • 推荐采用标准无铅回流焊工艺,严格按照厂商回流曲线进行,避免超过制造商规定的峰值温度和时长。
  • 在回流时注意逐步预热,减少热冲击,防止电容体内部电解液受热引起性能退化。
  • PCB 布局:留足焊盘尺寸与焊盘间距,保证良好焊接强度与散热;电容应靠近噪声源或电源引脚布置以发挥最佳滤波效果。
  • 在高温、高纹波或高压应用中,应考虑适当的额定裕量或选择更高寿命/更低 ESR 的型号。

五、可靠性与存储

  • 额定寿命 1000 小时 @ 105 ℃ 表明在高温极限下的长期稳定性;在较低温度下(如 85 ℃)其寿命将显著延长。选型时请根据实际工作温度与可靠性需求进行寿命估算与敞口裕度评估。
  • 存放条件:建议置于干燥、无腐蚀性气体、避免阳光直射的环境,温度与湿度按厂商建议保存,以免影响焊接性与电气特性。
  • 出货状态下请避免长期暴露于潮湿环境,若长期存放建议进行烘烤处理后再回流焊接(按厂方建议温度与时长)。

六、选型与包装建议

  • 对于对纹波电流、低 ESR 有更高要求的场合,可在同一尺寸或允许尺寸增长时优先考虑低 ESR 或固体电解质系列。
  • 采购与设计时,建议索取并阅读 CS1E220M-CRD54 的完整数据手册,确认 ESR、漏电流、典型纹波电流、回流曲线及推荐焊盘尺寸等详细参数。
  • 包装形式通常为卷带(Tape & Reel),适合自动贴片生产线;请在订购时与供应商确认具体包装与供货周期。

如需我帮您比对同类替代器件、提供具体 PCB 焊盘建议或解读数据手册中的电性能曲线,请告诉您的应用场景(电压、工作温度、纹波电流等),我会给出更具体的选型与布局建议。

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.

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
