CK1H010M-CRC54 产品概述

一、产品简要介绍

CK1H010M-CRC54 为先科(ST)品牌的一款贴片型铝电解电容器,额定容量 1µF,公差 ±20%,额定电压 50V。封装为 SMD,电容体直径 4.0mm,长度 5.4mm(D4×L5.4mm)。工作温度范围为 -40℃ ~ +105℃,在 105℃ 下寿命标称 2000 小时。此器件为极性电容(有极性),适合对体积、耐温与可靠性有一定要求的贴片化电源与滤波场合。

二、主要特性与优势

  • 小型化封装:D4×L5.4mm,适合高密度 PCB 布局及空间受限的设备。
  • 高电压耐受:50V 额定电压可用于中高电压母线旁路与滤波。
  • 宽温工作:-40℃ 至 +105℃,适应工业级环境。
  • 指定寿命:2000 hrs @ 105℃ 的加速寿命指标,便于评估长期可靠性。
  • SMD 贴片形式:兼容自动化贴装与回流焊工艺(具体焊接参数请参见厂方工艺说明)。

三、电气与机械参数(关键项)

  • 电容值:1µF
  • 公差:±20%
  • 额定电压:50V DC
  • 封装/尺寸:SMD,电容体 D4×L5.4mm
  • 工作温度:-40℃ ~ +105℃
  • 额定寿命:2000 小时 @ 105℃
  • 极性:有极性(请按标识正确安装)

注:本概述仅列出关键参数,关于等效串联电阻(ESR)、纹波电流、漏电流、耐振动冲击等详细电参数,请参考厂方完整规格书或向供应商索取测试报告。

四、适用场景

  • 开关电源输出滤波、初级/次级旁路与稳定化。
  • 高电压母线去耦(如有 24V、48V 或更高电压轨的场合)。
  • 工业控制、通信设备、电源模块以及要求较高工作温度的电子系统。
  • 体积受限但需要较高耐压的嵌入式应用。

五、安装与使用注意事项

  • 极性确认:铝电解电容为极性器件,必须严格按正负极安装,反向电压会导致失效甚至爆裂。
  • 回流焊工艺:通常支持回流焊,但回流温度、时间与升温速率应遵循厂方推荐曲线,避免过高峰值温度与过长保温时间。
  • 安全距离与顶端空间:电容顶部设有安全排气结构,板上应保留足够顶端空间以利散热与安全释放。
  • 降额使用:为延长寿命,建议在设计中对电压和温度进行适当降额;长期满载运行会加速老化。
  • 存储与预处理:避免潮湿高温储存;若长时间暴露于高湿环境,按厂家建议进行预烘烤再进行贴片回流。

六、可靠性与维护

2000 hrs@105℃ 的寿命指标为加速老化条件下的参考值。实际寿命受工作电压、温度、纹波电流等多重因素影响。关键设计建议:控制工作温度、减小纹波电流并避免长时间满额定电压运行,可显著提升使用寿命与性能稳定性。

七、采购与支持

  • 型号:CK1H010M-CRC54;品牌:ST(先科)。
  • 常见包装形式多为适合 SMT 的卷带(Reel)或托盘包装,具体包装与供货信息请向供应商或厂方确认。
  • 如需完整规格书、ESR/纹波曲线、回流焊建议曲线或可靠性测试数据,请向厂商索取最新技术资料以便设计验证与认证测试。

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
