KM1H4R7M0407直插铝电解电容产品概述

一、产品基本属性与品牌背景

KM1H4R7M0407是ROQANG(容强)品牌推出的一款通用型径向直插铝电解电容,定位中低功率电子电路的滤波、耦合及旁路应用。ROQANG作为国内专注铝电解电容研发生产的厂商,其产品覆盖消费电子、工业控制等领域,该型号主打“小体积、中等耐压、高适配性”,是紧凑电路设计的常规选型之一。

二、核心电性能参数详解

该电容的电性能参数符合行业通用标准,关键指标如下:

  1. 容值与精度:标称容值为4.7μF,允许偏差为**±20%**(电解电容常见精度等级,满足多数电路对容值偏差的需求);
  2. 额定电压:直流额定电压为50V,可长期稳定工作在直流50V及以下环境;若用于交流电路,需确保交流峰值电压不超过额定直流电压的70%(即≤35V);
  3. 温宽范围:参考ROQANG同类产品,支持**-40℃+105℃**的工作温度(部分批次标注-25℃+85℃,需以具体 datasheet 为准);
  4. 漏电流特性:符合铝电解电容标准,通常≤0.01CV μA(C为容值、V为额定电压,即≤4.7×50×0.01=2.35μA),保证电路低功耗。

三、封装与机械特性

KM1H4R7M0407采用径向直插封装,机械尺寸紧凑,具体参数:

  • 电容体尺寸:直径(φ)4mm,长度(L)7mm(不含引线);
  • 引脚间距:1.5mm(中心距),适配多数通用PCB板的1.5mm间距焊盘;
  • 引脚规格:镀锡铜材质,直径约0.5mm,耐焊接温度260℃/10s(符合IPC标准);
  • 安全设计:外壳顶部带防爆纹,过压/过温时优先破裂,避免爆炸风险。

注:产品标注“4x8mm封装”为引脚展开后的最大尺寸,实际电容体为φ4×7mm。

四、典型应用场景

因参数适配性强,该电容广泛用于:

  1. 电源电路:小型开关电源、LED驱动电源的输出滤波(滤除直流纹波)、输入耦合;
  2. 消费电子:收音机、遥控器、小型音响的音频耦合/旁路,玩具电路的电源稳压;
  3. 工业控制:低电压PLC模块、传感器电路的信号滤波,小型继电器驱动电路的辅助稳压;
  4. 智能家居:小型路由器、智能插座的电源辅助滤波,低功耗模块的信号耦合。

例如,在LED驱动电源中,可并联输出端滤除100Hz纹波,保证LED亮度稳定;在小型音响中,用于音频信号耦合,隔离直流干扰。

五、性能优势与可靠性

  1. 小体积高适配:φ4×7mm尺寸,适合智能手表、小型遥控器等紧凑设备;
  2. 宽温稳定:-40℃~+105℃温宽,适应南北温差环境;
  3. 长寿命设计:ROQANG成熟电解液配方,+105℃额定电压下寿命≥1000小时;
  4. 安全可靠:防爆纹+铝壳封装,降低过压损坏风险。

六、选型与使用注意事项

  1. 极性识别:引脚长端为正极,外壳“-”标识为负极,反接会导致电容损坏;
  2. 电压降额:实际工作电压建议≤40V(额定电压80%),延长寿命;
  3. 焊接规范:焊接温度≤260℃,时间≤10s,避免过热损坏电解液;
  4. 储存条件:未使用电容储存在20℃±5℃、湿度≤60%环境,储存期≤12个月,过期需复测容值。

该型号以高性价比和稳定性能,成为电子工程师设计紧凑电路时的常规选型之一,适配多数中低功率应用场景。

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
