LKME1251H221MF直插铝电解电容产品概述

LKME1251H221MF是永铭(Ymin)品牌推出的一款高性能径向直插铝电解电容,专为需要高纹波抑制能力、高温可靠性的电子设备设计,核心参数覆盖工业级与商业级主流应用场景,尺寸紧凑适配多种PCB布局。

一、核心规格参数

该电容的核心电气参数明确稳定,可满足多数电源滤波、储能需求:

  • 容值与精度:标称容值220μF,精度±20%(型号中“221”对应22×10¹μF,“MF”标识精度等级);
  • 额定电压:50V直流(DC),可承受短时间过压波动;
  • 纹波电流承载:1.23A(有效值)@100kHz,高频纹波抑制能力突出;
  • 温度范围:工作温度-40℃~+105℃,存储温度-40℃~+85℃(符合工业级环境要求)。

二、封装与尺寸设计

采用径向直插封装,尺寸紧凑便于安装:

  • 电容体尺寸:直径10mm(D10)×长度12.5mm(L12.5),型号中“1251”对应此尺寸编码;
  • 引脚间距:5mm,适配标准PCB插件孔距,无需特殊板设计;
  • 引脚类型:镀锡铜引脚,焊接牢固,抗腐蚀性能良好,适合回流焊或手工焊接。

三、电气性能与纹波抑制特性

作为铝电解电容,纹波电流承载能力是关键性能之一:

  • 高频纹波能力:1.23A@100kHz的纹波电流,可有效抑制开关电源、DC-DC转换器中的高频纹波,减少电磁干扰(EMI);
  • 容值稳定性:在-40℃~+105℃范围内,容值变化控制在合理区间,避免因温度波动影响电路性能;
  • 损耗特性:结合纹波电流参数可推断其等效串联电阻(ESR)较低,适合需要低损耗的应用场景。

四、可靠性与工作寿命

该电容的可靠性设计针对高温环境优化:

  • 工作寿命:10000小时@105℃,即在105℃持续高温下可稳定工作约1年,远超普通商业级电容(通常2000~5000小时@105℃);
  • 寿命延伸性:遵循Arrhenius定律,常温(25℃)下寿命可延长至数万小时,适合长期稳定运行的设备;
  • 抗振动性能:径向直插封装引脚强度较高,可承受一定程度的振动冲击,适配车载、工业控制等振动环境。

五、典型应用场景

基于参数特性,LKME1251H221MF适用于以下场景:

  1. 开关电源与线性电源:作为输出滤波电容,抑制纹波、稳定输出电压;
  2. 工业控制设备:PLC、变频器等设备的电源模块,适配工业级高温环境;
  3. 汽车电子:车载充电器、车载音响电源,满足宽温与振动要求;
  4. 通信设备:基站电源、路由器等设备的滤波电路,降低EMI干扰;
  5. 消费电子:大功率充电器、LED驱动电源,提供储能与滤波支持。

六、品牌与质量保障

永铭(Ymin)是国内专业铝电解电容制造商,产品符合IEC 60384-4、JIS C 5101等国际标准,通过RoHS、REACH等环保认证,质量稳定可靠。该电容生产过程中经过严格老化测试与参数筛选,确保批量一致性。

总结

LKME1251H221MF以高纹波承载、宽温可靠性、紧凑尺寸为核心优势,适配多种电子设备的电源滤波与储能需求,是工业级、商业级应用中替代进口电容的高性价比选择。

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
