KM1E470M0507 直插铝电解电容产品概述

KM1E470M0507是ROQANG(容强)品牌推出的通用型径向引线直插铝电解电容,专为中小功率电路的滤波、耦合等场景设计,兼具宽温度适应性与成本效益,适配多种工业及消费电子应用需求。

一、产品基本信息

该电容型号明确对应核心参数:KM1E470M0507中,“470”代表标称容值47μF(47×10¹μF),“M”表示容值精度±20%,“0507”对应电容体尺寸(直径5mm×长度7mm);封装类型为径向引线直插,引脚间距2mm,符合常规PCB插件工艺要求。

二、核心电气参数

作为通用电解电容,其电气性能满足主流应用场景:

  • 标称容值与精度:47μF,精度±20%——适配无需高精度容值的滤波、耦合电路,平衡性能与批量成本;
  • 额定电压:25V DC——支持低压直流电路的稳定工作,实际应用需遵循电压降额原则;
  • 纹波电流能力:80mA(@120kHz)——关键性能指标,可有效抑制中小功率电路的纹波干扰;
  • 温度与寿命:工作温度范围-40℃~+105℃,2000小时(@105℃)——宽温设计覆盖极端环境,高温寿命指标反映可靠性水平。

三、物理尺寸与封装设计

  • 尺寸规格:电容体直径5mm(D5)、长度7mm(L7),引脚间距2mm——小体积设计适配紧凑PCB布局(如机顶盒、路由器等小型设备);
  • 引脚设计:采用镀锡铜材质,引脚长度预留充足(常规10~15mm),便于波峰焊、手工焊等工艺,焊接后可剪脚至合适长度;
  • 极性标识:电容体表面通常印有极性符号(如“+”),引脚长脚为正极,需严格按极性焊接。

四、性能特点与应用优势

  1. 宽温度适应性:-40℃至+105℃的工作范围,可覆盖户外设备低温环境(如北方户外监控)、工业高温场景(如电源模块散热区);
  2. 纹波抑制效率:80mA@120kHz的纹波电流能力,满足开关电源输出滤波(如5V/1A电源的纹波控制)、音频电路耦合等需求;
  3. 成本效益平衡:通用型设计无额外高精度要求,适合批量应用(如消费电子、小型工业设备),降低整体BOM成本;
  4. 可靠性稳定:2000hrs@105℃的寿命指标,结合宽温设计,长期工作可靠性优于常规民用级电解电容。

五、典型应用场景

该电容适配以下主流电路:

  • 中小功率开关电源:输出滤波(如LED驱动电源、路由器电源模块);
  • 音频电路:功放前级耦合、信号滤波(如小型音箱、耳机放大器);
  • 工业控制电路:电源滤波、信号耦合(如PLC辅助电路、传感器模块);
  • 消费电子:机顶盒、智能电视、智能家居设备的电源单元;
  • 汽车辅助电路:内饰电子(如车载充电器、中控小屏)的低压滤波(需确认整车环境温度符合要求)。

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≤额定电压的80%(即≤20V DC),避免过压导致漏电流增大、击穿;
  2. 纹波电流限制:实际纹波电流需小于80mA(@120kHz),若电路纹波频率偏离120kHz,需参考厂家提供的纹波电流-频率曲线;
  3. 温度管控:避免长期工作在105℃以上环境,否则寿命呈指数级下降;
  4. 焊接工艺:波峰焊温度≤260℃,焊接时间≤10秒;手工焊温度≤350℃,时间≤3秒,防止高温损伤电容内部电解液;
  5. 极性严格:反接会导致电容发热、漏电流剧增,甚至爆炸,必须按极性标识焊接。

KM1E470M0507凭借小体积、宽温、平衡的性能与成本,成为通用低压电解电容的优选之一,适配多场景的批量应用需求。

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
