CS1H331M-CRG10 贴片铝电解电容产品概述

一、产品基本属性定位

CS1H331M-CRG10是容强(ROQANG)品牌推出的一款贴片型铝电解电容,属于中低压、中等容值的常规SMD系列产品。该电容针对小型化PCB设计需求优化,兼顾电气性能与体积紧凑性,适用于消费电子、工业控制、通信设备等多领域的滤波、储能场景,是常规电路中替代插件电容的高性价比选择。

二、核心电气性能参数

该电容的关键指标明确,满足绝大多数常规电路的基本需求:

  • 容值与精度:标称容值330μF(型号编码“331”对应33×10¹μF),精度±20%,符合工业级铝电解电容的常见精度标准,可覆盖一般滤波、储能场景的容值偏差要求;
  • 额定电压:直流额定电压50V,适用于工作电压≤40V(建议留20%裕量)的低压电路,避免过压损坏;
  • 纹波电流能力:285mA(@120Hz),120Hz为整流电路的典型纹波频率,该指标体现电容耐受纹波的能力,可有效抑制电路噪声,减少电源纹波对敏感器件的干扰;
  • 温度特性:工作温度范围-40℃~+105℃,覆盖低温存储(如北方冬季户外设备)与高温工作(如密闭机箱内)的常规环境;
  • 寿命表现:105℃高温下额定寿命2000小时,若工作温度降低,寿命按Arrhenius定律显著延长(如温度每降10℃,寿命约翻倍),实际应用可靠性更有保障。

三、结构与封装特征

  • 封装形式:贴片式(SMD),兼容自动贴片机生产,可实现高效批量组装,适合现代化SMT生产线;
  • 体积尺寸:电容体直径(D)10mm,长度(L)10.5mm,属于小型化封装,可替代同参数插件电容,节省PCB空间(如高密度电源模块、小型消费电子);
  • 结构设计:采用铝电解电容常规结构(铝箔电极、液态电解质、隔膜),贴片焊盘设计稳定,焊接可靠性高,不易出现虚焊、脱焊问题;
  • 引脚间距:常规贴片铝电解电容引脚间距约5mm(需结合具体封装确认),适配多数PCB的焊盘布局。

四、典型应用场景

结合性能与体积特点,该电容主要适用于以下场景:

  1. 小型开关电源滤波:机顶盒、路由器、LED驱动电源的输出滤波,50V额定电压匹配低压电源需求,330μF容值可平滑输出纹波;
  2. 工业控制辅助电路:PLC模块、传感器电源的滤波,宽温范围适配工业现场的高低温环境;
  3. 通信设备电源模块:小型基站、无线AP的电源滤波,小型化封装适合通信设备的高密度PCB布局;
  4. 车载低压辅助电路:车载音响、仪表盘的辅助电源滤波(需注意:若需严格车载认证,需确认是否满足AEC-Q200标准,常规宽温特性可适配一般车载辅助电路);
  5. 消费电子储能:便携式设备的辅助储能(如移动电源的辅助滤波),体积紧凑不占用过多空间。

五、选型与使用注意事项

为确保电容性能稳定、寿命可靠,使用时需注意:

  1. 电压裕量:实际工作电压≤40V(额定电压的80%),避免过压导致漏液、鼓包;
  2. 纹波电流匹配:电路实际纹波电流≤285mA(@120Hz),若纹波过大,电容发热会加速老化;
  3. 温度适配:长期工作温度≥105℃时,需更换125℃等级电容;
  4. 体积与焊盘:PCB需预留D10mm×L10.5mm的安装空间,焊盘尺寸需匹配引脚间距;
  5. 精度需求:±20%精度满足常规滤波,高精度场景(如医疗设备)需选±10%及以上精度电容。

六、品牌与可靠性说明

该电容由容强(ROQANG)品牌生产,作为国内专业铝电解电容厂商,其产品通过了常规可靠性测试(高温寿命、温度循环、耐纹波测试),可满足大多数常规应用的可靠性要求,是中小批量电路设计的高性价比选择。

总结:CS1H331M-CRG10以小型化、宽温特性、稳定纹波能力为核心优势,适配多领域常规电路需求,是替代插件电容的实用选型。

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.
