LKME1401K181MF 直插铝电解电容产品概述

LKME1401K181MF是永铭(Ymin)品牌推出的工业级径向直插铝电解电容,针对中高压、高频纹波场景设计,兼具长寿命、紧凑尺寸与可靠性能,广泛适配工业电源、通信设备等领域的滤波/耦合需求。

一、产品核心身份与定位

  • 品牌背书:永铭(Ymin)是国内专注铝电解电容研发的制造商,产品覆盖工业、汽车、通信等领域,以高可靠性著称;
  • 型号解析:型号中“181”对应标称容值180μF(18×10¹),“80V”为额定电压,“10x14mm”是电容体尺寸,明确指向中高压直插电容;
  • 定位:面向工业级中压滤波场景,满足105℃高温环境下的持续工作需求,替代同参数普通电解电容的可靠性短板。

二、关键电气性能参数

1. 容值与精度

标称容值180μF,精度±20%——满足多数滤波电路的误差要求,避免因容值偏差导致的输出电压波动,适配对精度要求不苛刻的工业应用。

2. 额定电压

80V DC——适用于中高压电路(如220V AC整流后次级电路的中压段),建议实际工作电压留20%安全余量(≤64V DC),避免过压损坏。

3. 纹波电流能力

980mA(@100kHz,20℃)——高频(100kHz)下的纹波承受能力突出,远高于同容值普通电容,可有效抑制开关电源等高频纹波,减少并联电容数量,节省PCB空间。

4. 工作寿命

10000小时(@105℃)——采用耐高温电解液与电极材料,高温下电解液干涸速度慢,容值衰减率低,适合工业设备、车载电子等持续高温场景。

三、物理封装与尺寸规格

1. 封装类型

径向引线直插——引脚从电容体两端引出,垂直插入PCB,兼容传统插件工艺,无需特殊焊接设备。

2. 尺寸参数

  • 电容体直径:10mm(Φ10);
  • 电容体长度:14mm(L14);
  • 引脚间距:5mm——适配标准插件焊盘,无需修改PCB布局,安装便捷。

3. 引脚特性

表面镀锡处理,焊接性好,引脚长度符合行业标准(约10-15mm),可直接插入常规焊盘。

四、可靠性与环境适应性

  1. 高温稳定性:105℃下连续工作10000小时,通过严苛的高温老化测试,避免工业环境下的早期失效;
  2. 耐振动性能:直插引脚连接可靠,适配常规工业振动场景(如机床、变频器设备);
  3. 抗纹波衰减:高频纹波下的损耗低,长期使用后纹波电流承受能力无明显下降。

五、典型应用场景

  1. 工业开关电源:次级滤波电路,抑制高频纹波,稳定输出电压;
  2. 通信设备:基站电源、路由器电源的直流滤波,满足长寿命与中高压需求;
  3. 车载电子:车载充电器、车载音响的电源滤波(覆盖-40℃至+105℃车载温度范围);
  4. 工业控制:PLC、变频器的辅助电源滤波,提升设备运行稳定性。

六、选型与使用注意事项

  1. 电压余量:实际工作电压≤额定值的80%(≤64V DC),避免过压击穿;
  2. 纹波匹配:电路纹波电流峰值≤980mA@100kHz(高频场景可适当放宽);
  3. 焊接工艺:焊接温度≤260℃,单次焊接时间≤5秒,避免损坏电容体;
  4. 环境温度:适用范围-40℃至+105℃,超出范围需降额使用;
  5. 尺寸适配:确认PCB焊盘间距为5mm,电容体尺寸(Φ10×L14)与安装空间匹配。

总结

LKME1401K181MF以中高压、高纹波承受、长寿命为核心优势,结合紧凑的径向直插封装,成为工业、通信领域中压滤波场景的高性价比选择。永铭的品牌可靠性进一步保障了产品在严苛环境下的稳定运行,适合对成本与性能平衡要求较高的批量应用。

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
