KM1A471M0611 产品概述

一、产品简介

KM1A471M0611 为 ROQANG(容强)系列直插式铝电解电容器,标称容量 470µF,容量公差 ±20%,额定电压 10V。该器件为插件封装,针脚间距 2.5mm,设计用于工业级电源滤波与去耦场合,具有良好的纹波承受能力与耐高温特性。

二、主要参数

  • 容值:470µF(±20%)
  • 额定电压:10V
  • 纹波电流:220mA @ 120kHz
  • 针脚间距:2.5mm(直插)
  • 工作温度:-40℃ ~ +105℃
  • 额定寿命:2000 小时 @ 105℃
  • 封装形式:插件(直插)

三、性能特点

  • 高纹波承受:220mA@120kHz 的额定纹波电流,适合中高频开关电源滤波与输出侧去耦。
  • 宽温度工作:-40℃ 至 +105℃,能满足多数工业与民用电子环境的温度要求。
  • 紧凑针距:2.5mm 插件形式,便于传统穿孔板与波峰焊/手工焊接装配。
  • 稳定可靠:2000小时@105℃ 的工作寿命指标,适用于对可靠性有一定要求的电源回路。

四、典型应用

  • 开关电源输出滤波与去耦
  • DC-DC 转换器输入/输出稳定
  • 工业控制及仪表电源滤波
  • 消费类电子电源模块与音频电路电源旁路

五、使用与设计建议

  • 极性注意:铝电解电容为极性器件,接入电路时务必确认正负极方向,避免反接引发失效。
  • 电压与温度降额:为延长寿命,建议根据实际温升与使用环境对额定电压和最高工作温度进行适当降额设计。经验上在接近最高温度或连续高纹波工况下应留有裕量。
  • 纹波与散热:在高纹波工况下注意器件散热与布局,尽量靠近热源或提供散热路径以减小温升。
  • 焊接与安装:插件封装适合波峰与手工焊接,焊接时应控制加热温度与时间以避免电解质和封装材料受损。
  • 储存与预处理:长时间储存后建议按厂家建议进行老化或检测(漏电流/容量/ESR)后使用。

六、选型提示

选择 KM1A471M0611 时,若系统有更高纹波或更长寿命需求,可考虑容量相同但额定电压更高或寿命等级更高的型号;若空间或低阻抗要求严格,可结合低ESR 封装或固态电容作混合设计以优化性能。容强(ROQANG)系列在稳定性与可焊性上有良好表现,适合批量生产与维修替换。

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
