LKMD1601J181MF 直插铝电解电容产品概述

一、产品基本信息

LKMD1601J181MF是永铭(Ymin)品牌推出的径向直插铝电解电容,专为中低压、中容量的滤波、储能及耦合场景设计。作为铝电解电容的典型代表,该产品兼顾容量密度与成本优势,适配多种工业及消费电子领域的电路需求。型号命名中,“181”对应180μF容值,“J”代表±20%精度,明确了核心性能指标,属于通用型中容量电容范畴。

二、核心电气参数详解

该电容的电气参数直接决定应用适配性,关键指标及实际意义如下:

  1. 容值与精度:标称180μF,精度±20%,满足大部分通用电路对容量偏差的要求(如电源滤波无需极端精准匹配),可覆盖常见直流/交流信号的储能需求。
  2. 额定电压:63V直流额定电压,适配12V/24V系统的升压电路、低压电源滤波等场景(需留20%以上电压余量,避免过压损坏)。
  3. 纹波电流与ESR:100kHz频率下,耐受纹波电流1.19mA,等效串联电阻(ESR)190mΩ。纹波电流反映电容耐受交流纹波的能力,ESR则影响损耗与纹波抑制——低ESR可减少电路发热,提升滤波效率,适合对纹波要求较高的电源模块。

三、机械与封装特性

LKMD1601J181MF采用径向引线封装,机械尺寸紧凑,具体参数:

  • 电容体直径8mm,长度16mm(不含引线);
  • 引脚间距3.5mm,引线直径符合标准直插规范,便于PCB焊接。
    紧凑设计使其可在空间受限的电路板中灵活布局,尤其适合小型化电源、便携式设备及高密度工业控制板。

四、典型应用场景

结合性能特点,该电容适用于以下场景:

  1. 低压电源滤波:12V/24V直流电源输出滤波、开关电源次级滤波,抑制纹波噪声,提升电源稳定性;
  2. 音频电路:音频放大器耦合电容或电源滤波,减少噪声干扰,保证信号纯净度;
  3. 工业控制:PLC、传感器模块的电源滤波与储能,适配-40℃~105℃宽温环境;
  4. 汽车电子:车载12V系统辅助电源滤波,耐温性能满足车载高温需求。

五、可靠性与寿命说明

该电容工作寿命为10000小时@105℃,符合工业级电容要求。铝电解电容寿命与温度强相关:实际温度每降低10℃,寿命约延长1倍(如70℃环境下理论寿命超40000小时),大幅降低长期更换成本。此外,其电解液配方与封装设计保证了高温下的容量稳定性,减少容值衰减。

六、选型与使用注意事项

为确保长期可靠工作,需注意:

  1. 电压余量:实际工作电压不超过额定电压的80%(≤50.4V),避免过压鼓包;
  2. 纹波电流匹配:电路纹波电流需小于1.19mA@100kHz(频率变化需参考厂家曲线);
  3. 温度适配:避免长期超105℃工作,高温场景需加散热;
  4. 焊接规范:焊接温度≤260℃,时间≤3秒,避免损坏电容体。

总结

LKMD1601J181MF凭借紧凑尺寸、稳定性能及可靠寿命,成为通用低压铝电解电容的高性价比选择,覆盖消费电子到工业控制的多场景需求,适合对成本敏感且需兼顾性能的电路设计。

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
