LKMD1151V221MF 直插铝电解电容产品概述

一、产品核心定位

LKMD1151V221MF是永铭(Ymin)品牌推出的径向引线直插铝电解电容,针对中低压、长寿命场景设计,兼顾体积紧凑性与性能可靠性,广泛适配工业控制、消费电子、通信设备等领域的滤波、储能需求,是替代普通短寿命电解电容的高性价比选择。

二、关键参数深度解析

该产品核心参数围绕“容值、电压、寿命、尺寸”四大维度,具体解析如下:

  • 容值与精度:标称容值220μF(行业常规三位数标注“221”,前两位“22”为有效数字,第三位“1”代表10¹倍,即22×10¹=220μF),精度±20%——符合铝电解电容典型精度范围,兼顾成本与实际应用可靠性,无需高精度场景下可有效控制成本;
  • 额定电压:35V直流电压(DC)——覆盖多数低压电源系统(如5V、12V、24V输出电路),是工业控制、消费电子电源滤波的常用电压等级,长期工作时能稳定承受额定电压,避免漏电流过大或击穿风险;
  • 工作寿命:10000hrs@105℃——核心优势之一,相比普通电解电容(通常2000-5000hrs@105℃)寿命提升2-5倍,可满足长期连续工作设备需求;且根据Arrhenius定律,环境温度每降低10℃,寿命约延长2倍(如70℃时寿命可达约80000hrs),实际应用场景下寿命更可观;
  • 尺寸规格:电容体直径(D)8mm,长度(L)11.5mm,脚间距3.5mm——径向引线直插设计,脚间距适配多数PCB板插件焊盘,体积紧凑适合小型化设备布局。

三、封装与安装特性

该产品采用径向引线直插封装,具有以下安装优势:

  1. 安装便捷:直插式设计无需特殊工具,普通波峰焊、手工焊均可完成,适合批量生产与小批量调试;
  2. 兼容性强:脚间距3.5mm、电容体尺寸8×11.5mm,与市场同规格电容引脚布局一致,可直接替换旧款电容,无需修改PCB板;
  3. 空间利用率高:径向引线从电容体两端引出,相比轴向引线更节省电路板空间,适合垂直安装场景(如PCB板垂直方向布局)。

四、性能优势与典型应用

1. 核心性能优势

  • 长寿命可靠性:10000hrs@105℃设计,降低设备维护成本,减少电容失效导致的停机风险,适合24小时连续工作的工业设备;
  • 宽温稳定工作:额定温度105℃,可在高温环境(如工业控制柜、汽车发动机舱周边)下稳定运行,容值衰减率低;
  • 低漏电流:符合铝电解电容漏电流标准(≤3×√C×V/1000,C为容值μF、V为额定电压),长期工作时漏电流稳定,不影响电路性能;
  • 成本效益平衡:在长寿命、宽温特性下保持高性价比,相比进口同规格电容价格更具优势。

2. 典型应用场景

  • 工业控制:PLC、变频器、伺服驱动器、工业电源等(长期连续工作+高温环境需求);
  • 消费电子:电源适配器、机顶盒、路由器、智能家电(如洗衣机、空调)的电源滤波电路(体积紧凑+稳定滤波需求);
  • 通信设备:基站电源、交换机、光传输设备的直流滤波环节(可靠储能+信号稳定需求);
  • 汽车电子:车载电源、仪表盘、车载音响(非车规高温场景适配)。

五、永铭品牌背书

永铭(Ymin)作为国内铝电解电容资深制造商,拥有20余年研发生产经验,产品覆盖高压、长寿命、高频等系列,通过ISO9001与RoHS认证;其电容以“高可靠性、长寿命、性价比高”著称,广泛应用于国内外工业、消费电子、通信领域,是众多OEM/ODM厂商首选品牌之一。

LKMD1151V221MF凭借长寿命、宽温适应性、紧凑体积与高性价比,成为中低压滤波、储能场景的优质选择,可有效满足多样化应用需求。

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
