CS1H100M-CRD54 产品概述

一、产品概述

CS1H100M-CRD54 为贴片型铝电解电容,公称容量 10µF,容差 ±20%,额定直流电压 50V。电容体外形为圆柱 SMD 封装,直径 5.0mm,长度 5.4mm,品牌为 ST(先科)。该系列器件专为高密度贴片电路设计,适用于对体积、可靠性有一定要求的电源去耦与滤波场合。

二、主要参数

  • 容值:10µF ±20%
  • 额定电压:50V DC
  • 封装尺寸:D5 × L5.4 mm(贴片)
  • 工作温度范围:-40℃ ~ +105℃
  • 额定寿命:1000 小时 @ 105℃
  • 极性:有极(铝电解电容,需注意极性连接)
  • 封装形式:SMD(请在订购时确认包装方式,如卷带卷盘)

注:关于等效串联电阻(ESR)、漏电流、纹波电流等电性能指标,应以厂商正式数据手册为准或通过样品测量确认。

三、主要特性与优点

  • 紧凑封装:5mm×5.4mm 的小体积,便于高密度组装与空间受限的电路板布局。
  • 高耐温:额定工作温度至 105℃,适合工业级或高温环境应用。
  • 标准化寿命:1000 小时 @ 105℃ 的寿命等级,便于可靠性评估与系统设计。
  • 表面贴装:适配自动贴片与回流焊工艺,提高生产效率。
  • 成本效益:铝电解电容在容量/体积比与成本上具有优势,适合中低频滤波与去耦。

四、典型应用场景

  • 开关电源输出滤波与能量储备。
  • DC/DC 转换器的输入/输出去耦与稳定。
  • 模拟电路与功率放大器的耦合与旁路。
  • 工业控制、仪表及通信设备中对较大容值的贴片滤波需求。
    注意:铝电解电容为有极器件,不能用于交流无极应用或反向偏置场合。

五、设计与装配注意事项

  • 极性识别:PCB 设计时明确正负极标识,安装时严格遵循极性。
  • 焊接工艺:尽管为 SMD,仍建议按照厂方回流曲线进行焊接;避免长时间过高温度或多次回流。若需手工焊接,注意热量控制以防电解质损伤。
  • 纹波与散热:合理评估工作纹波电流并留有余量,电容温升会影响寿命与性能。必要时并联多个电容以降低 ESR 或提升纹波处理能力。
  • 封装布局:周围留有适当间隙以利散热,并考虑振动隔离以提高可靠性。

六、可靠性与寿命管理

  • 该型号寿命以 105℃ 工况下 1000 小时为基准;在较低温度下寿命会显著延长。工程上常用经验:温度每降低 10℃,寿命可显著增加(以厂方加速寿命模型或实际测试为准)。
  • 对于长期可靠性设计,建议对额定电压做适度降额使用(例如将工作电压控制在额定值的 70%—80% 范围内,具体降额策略应基于系统要求与厂方建议)。
  • 在关键应用中,应考虑老化测试、寿命释放测试和高/低温循环测试以验证可靠性。

七、采购与测试建议

  • 订购前核对完整型号、包装形式与生产批次,必要时索取并核对原厂数据手册。
  • 对关键电性能(ESR、漏电流、纹波电流)建议进行样品测量验证,以确保满足实际工况需求。
  • 建议在量产前完成回流焊兼容性验证与加速寿命测试,尤其是高温或高纹波场合。

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
