LKMC1101H101MF 直插铝电解电容产品概述

LKMC1101H101MF是永铭(Ymin)品牌推出的径向引线直插铝电解电容,针对高频滤波、电源稳压等场景优化设计,兼具小尺寸、低损耗与高可靠性,是消费电子、工业控制等领域的通用型电容解决方案。

一、产品核心身份与定位

该电容属于永铭常规系列电解电容,型号编码明确其关键属性:

  • "LKMC"为系列标识,代表直插铝电解电容;
  • "1101"对应机械尺寸(直径6.3mm×长度11mm);
  • "H"表示额定电压50V(永铭电压编码规则);
  • "101M"表示容值100μF(101×100μF)、精度±20%(M级)。

产品定位为中低压、高频适配、小体积的通用电解电容,覆盖从消费电子到工业级的多场景需求,平衡了性能与成本效益。

二、关键电气性能参数

电气参数是电容选型的核心依据,LKMC1101H101MF的关键指标如下:

  1. 容值与精度:100μF±20%,满足大多数滤波、耦合场景的容值需求,M级精度可覆盖非超精密应用(如电源滤波无需±10%精度);
  2. 额定电压:50V(DC),是电容安全工作的最高电压,实际应用需遵循降额原则(建议不超35V);
  3. 高频纹波能力:687mA@100kHz(纹波电流),支持高频开关电源的输出滤波,有效抑制100kHz左右的高频纹波噪声;
  4. 等效串联电阻(ESR):180mΩ@100kHz,相比普通电解电容(通常200~300mΩ@100kHz)更低,可减少电容自身损耗,提升电源效率,降低发热;
  5. 温度特性:工作温度范围-40℃~+105℃(永铭同系列常规参数),适配宽温环境。

三、机械结构与封装规格

机械参数决定了电容在PCB上的安装适配性,具体如下:

  • 封装类型:径向引线(两引脚平行于电容体轴线),适合手工焊接与波峰焊工艺;
  • 引脚间距:2.5mm,匹配常规PCB焊盘设计,无需特殊开孔;
  • 电容体尺寸:直径6.3mm×长度11mm(含引脚除外),属于小型化设计,可用于紧凑空间的电源模块、小型电子设备(如智能手表充电器);
  • 引脚直径:约0.6mm,焊接牢固性好,不易出现虚焊。

四、可靠性与环境适应性

该电容的可靠性指标满足工业级与消费级的双重需求:

  • 工作寿命:9000hrs@105℃,即在105℃高温环境下可连续工作9000小时(约1年),比普通电解电容(通常3000~5000hrs@105℃)寿命更长,适合高温工作场景(如工业设备内部、电源模块);
  • 耐温稳定性:宽温范围下容值衰减率低,-40℃时容值无明显下降,+105℃时长时间工作ESR上升缓慢;
  • 耐纹波可靠性:高频纹波电流能力稳定,长期工作不易出现漏液、鼓包等失效问题。

五、典型应用场景

基于其电气与机械特性,LKMC1101H101MF的典型应用包括:

  1. 开关电源输出滤波:抑制高频开关纹波,提升输出电压稳定性,适用于手机充电器、机顶盒电源;
  2. 音频电路耦合/滤波:低ESR减少信号损耗,提升音频信噪比,用于小型功放、耳机放大器;
  3. 工业控制电源:高温环境下长寿命,满足PLC、传感器电源的可靠性需求;
  4. 消费电子辅助电路:小尺寸适配智能手表、蓝牙耳机等便携设备的电源模块;
  5. 汽车电子(非高压):宽温范围适配车载辅助电路(如车载充电器、中控电源)。

六、选型与使用注意事项

为确保电容长期稳定工作,需注意以下要点:

  1. 电压降额:实际工作电压建议不超过35V(50V×70%),避免过压导致电容漏液、失效;
  2. 纹波电流匹配:负载纹波电流需低于687mA@100kHz,若负载纹波较大,可并联2~3个电容分担电流;
  3. 尺寸适配:PCB布局需预留电容体周边0.5mm以上间隙,避免与其他元件干涉;
  4. 焊接工艺:焊接温度不超过260℃(持续时间≤10s),避免高温损坏电容;
  5. 环境防护:若工作环境潮湿,建议采用涂覆工艺保护电容引脚,防止氧化。

该电容以高性价比、小体积、高可靠性的特点,成为多领域电子设计的优选电解电容之一,可有效满足高频滤波、电源稳压等基础需求。

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.
