KM1C471M0812直插铝电解电容产品概述

一、产品基本属性

该产品为ROQANG(容强)品牌旗下的直插式铝电解电容,型号为KM1C471M0812。型号编码中:

  • KM1为系列标识,代表容强常规直插铝电解系列;
  • C对应额定电压16V(铝电解电容电压编码行业惯例);
  • 471表示标称容值470μF(前两位为有效数字,第三位为倍率);
  • 0812明确电容体尺寸为直径8mm×长度12mm。

二、核心电气参数

2.1 容值与精度

标称容值为470μF,精度±20%,满足大多数常规电路对电容容量的需求(如电源滤波、耦合环节无需超高精度匹配)。

2.2 额定电压与极性

  • 额定电压16V DC,可稳定承受16V以下直流工作电压,避免过压击穿风险;
  • 铝电解电容为有极性设计,需严格匹配电路极性(通常长引脚为正极、短引脚为负极)。

2.3 纹波电流能力

最大纹波电流为310mA(@120kHz),可有效抑制高频纹波干扰(如开关电源的高频噪声),提升电源输出稳定性。

2.4 温度与寿命特性

  • 工作温度范围**-40℃~+105℃**,适应高低温环境(如工业户外设备、车载电子低温启动场景);
  • 工作寿命2000小时(@105℃),高温环境下仍能保持较长工作周期,降低设备维护成本(常温下寿命可显著延长)。

三、物理封装规格

3.1 封装类型

采用径向引线(插件式),兼容手工焊接或自动插件工艺,无需特殊贴装设备。

3.2 尺寸参数

  • 电容体:直径8mm×长度12mm(D8×L12mm),紧凑体积适合小型化PCB设计;
  • 引脚间距:3.5mm,与标准插件焊盘间距匹配,无需定制PCB;
  • 引脚材质:铜质引脚,焊接性能良好,抗氧化性满足常规使用需求。

四、性能优势与适用场景

4.1 核心性能优势

  1. 宽温稳定性:在-40℃低温至105℃高温范围内,容值变化率符合行业标准,性能波动小;
  2. 抗纹波能力强:310mA@120kHz的纹波承载能力,优于部分同规格普通铝电解电容;
  3. 长寿命设计:2000hrs@105℃的寿命指标,适合长期运行的工业/消费电子设备;
  4. 安装便捷:直插设计无需复杂贴装,降低生产工艺成本。

4.2 典型应用领域

  • 电源系统:开关电源、线性电源的滤波/储能环节;
  • 消费电子:机顶盒、路由器、LED驱动电源等小型设备;
  • 工业控制:PLC、传感器模块、电机驱动电路的滤波;
  • 音频电路:功放、音箱的耦合/滤波电容;
  • 车载电子:车载充电器、中控系统辅助电源(需确认温度适配场景)。

五、选型与使用注意事项

  1. 电压匹配:电路工作电压需≤16V,避免过压击穿;
  2. 纹波限制:实际电路纹波电流需低于310mA@120kHz,防止电容过热;
  3. 温度管控:长期工作在105℃时,需预留散热空间(如增加PCB散热铜箔);
  4. 焊接规范:焊接温度≤260℃,焊接时间≤3秒,避免损伤电容内部电解液;
  5. 极性确认:安装前需核对引脚极性,反接可能导致电容爆炸或性能失效。

该产品以高性价比、稳定性能适配多场景低压电路需求,是常规电子设备滤波/储能环节的可靠选择。

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
