CS1H331M-CRG10 贴片电解电容产品概述

一、产品基本定位

CS1H331M-CRG10是先科(ST)推出的一款中高压贴片铝电解电容,针对电子设备的电源滤波、能量存储等核心功能设计,兼顾小型化封装与宽温可靠性,适配自动化SMT贴装工艺,可满足工业、消费电子等多领域的常规应用需求。

二、核心性能参数解析

该电容关键参数明确,符合行业通用规范:

  • 容值与精度:标称容值330μF(型号中“331”为容值代码,代表33×10¹μF),精度±20%,满足工业级设备对容值偏差的常规要求;
  • 额定电压:50V DC(电解电容额定电压特指直流工作电压,交流应用需降额);
  • 封装尺寸:电容体直径10mm,长度10.5mm,属于贴片封装10×10.5mm规格,体积紧凑,适配高密度PCB布局;
  • 温宽与寿命:工作温度范围-40℃~+105℃,高温下额定寿命2000hrs(@105℃),符合JEITA EIA-625标准,常温下寿命显著延长;
  • 其他特性:低漏电流设计(典型值≤0.01CV μA),高频阻抗特性良好,适合电源纹波抑制。

三、结构与工艺优势

先科针对该型号优化了结构设计,提升可靠性与适配性:

  1. 电极与电解质:采用腐蚀铝箔作为阳极,增大有效表面积;搭配低阻抗电解液,降低ESR(等效串联电阻),减少发热与纹波损耗;
  2. 封装工艺:外壳为耐高温环氧树脂,耐振动(10~2000Hz,1.5g加速度)、耐冲击,且适配回流焊/波峰焊工艺(需遵循焊接温度曲线);
  3. 引脚设计:镀锡铜引脚,抗氧化性能好,焊接牢固,避免虚焊问题。

四、典型应用场景

基于参数与特性,该电容适用于以下场景:

  1. 工业控制设备:PLC(可编程逻辑控制器)、伺服驱动器的电源滤波模块,适应工业现场-20℃~+60℃的温度波动;
  2. 消费电子电源:高端笔记本电源适配器、4K显示器的电源板,满足小型化与纹波抑制需求;
  3. 通信辅助设备:小型基站、光纤收发器的电源滤波,保证信号稳定;
  4. 家电控制板:变频空调、滚筒洗衣机的主控板,适应室内环境温度变化;
  5. 汽车低端电子:部分车载辅助设备(如车载充电器),兼容-40℃~+85℃的工作环境(需确认整车厂降额要求)。

五、可靠性与寿命说明

该电容寿命遵循Arrhenius定律:温度每降低10℃,寿命约提升2倍,实际寿命表现如下:

  • 85℃环境下:约8000hrs;
  • 60℃环境下:约32000hrs;
  • 25℃常温下:可达数年,满足大部分电子设备3~5年的设计寿命要求。

此外,该型号通过湿度测试(60℃/95%RH,1000hrs)、温度循环测试(-40℃~+105℃,500次循环),可靠性符合行业标准。

六、选型与使用注意事项

为保证电容性能与寿命,需注意以下要点:

  1. 电压降额:实际工作电压建议不超过额定电压的80%(即40V),避免过压导致氧化膜击穿;
  2. 焊接规范:回流焊峰值温度≤260℃(持续时间≤10s),波峰焊温度≤240℃(持续时间≤5s),避免高温损坏电解质;
  3. 极性识别:电容顶部有“+”标识,必须与PCB焊盘极性一致,反接会导致漏电流骤增、甚至爆炸;
  4. 存储条件:未使用的电容应存储在-10℃40℃、湿度40%60%RH的环境,避免长期暴露在高湿环境(否则降低焊接性能);
  5. 机械应力:焊接后避免引脚过度弯曲,安装时减少机械振动,防止电容体开裂。

该型号以高性价比、宽温可靠性为核心优势,是电子设备电源设计中常规滤波/储能的优选贴片电解电容之一。

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
