LKME2002C820MF 直插铝电解电容产品概述

LKME2002C820MF是永铭(Ymin)推出的一款中高压径向引线直插铝电解电容,针对工业级设备的滤波、储能及电压稳定需求设计,兼具高可靠性与紧凑体积,适用于多种高频纹波场景。

一、产品核心定位与典型应用

该电容聚焦中高压工业场景,以160V额定电压、10000hrs@105℃长寿命为核心优势,适配以下典型应用:

  • 开关电源模块:抑制高频纹波,稳定输出电压;
  • 工业变频器:支撑电机驱动电路的储能与滤波;
  • 光伏逆变器:处理直流侧电压波动,提升转换效率;
  • 工业控制设备:保障PLC、传感器等电路的电源稳定性。

二、关键电气性能参数解析

2.1 容值与精度

标称容值82μF,精度±20%(工业级常规精度),满足多数滤波、储能场景的容值需求,无需高精度校准即可稳定工作,兼顾性能与成本。

2.2 额定电压与安全余量

额定电压160V DC,是中高压电路的核心适配参数,设计时需结合实际工作电压留足降额空间(建议降额30%以上),避免过压击穿风险,确保长期可靠性。

2.3 纹波电流能力

高频纹波电流(100kHz)耐受值为1.02A,这是铝电解电容的关键性能指标——高频纹波会导致电容内部发热,该参数直接决定电容在开关电源等高频场景下的寿命与稳定性。1.02A的耐受值可覆盖多数中小功率开关电源的纹波需求。

2.4 工作寿命与环境耐受

连续工作寿命10000hrs@105℃,远高于普通85℃级电容(通常2000-5000hrs),适配高温环境(如设备内部发热区域),可显著降低工业设备的维护成本。

三、机械结构与封装特性

3.1 封装类型

采用径向引线直插封装,引脚从电容体两端引出,适合传统PCB插件工艺,焊接可靠性高,机械强度满足工业设备的振动要求。

3.2 尺寸规格

  • 电容体直径:10mm(紧凑体积,节省PCB空间,适配高密度布局);
  • 电容体长度:20mm(平衡容值与体积,避免过度小型化导致性能下降);
  • 引脚间距:5mm(符合标准插件焊盘设计,无需特殊定制PCB)。

3.3 引脚设计

引脚为镀锡铜材质,焊接性好,可承受多次焊接操作,且引脚长度适配多数PCB厚度,安装时无需额外剪脚,提升生产效率。

四、可靠性与环境适应性

4.1 高温稳定性

105℃连续工作温度下,电容的容值衰减、漏电流增长均控制在行业标准内,经过老化测试验证,可长期稳定运行于高温工业环境(如变频器内部、光伏逆变器散热区)。

4.2 抗纹波老化

1.02A@100kHz的纹波电流耐受值,结合长寿命设计,可有效抑制电容因纹波发热导致的电解液干涸、容值衰减问题,延长实际使用寿命,降低设备故障风险。

4.3 存储与运输

存储环境建议为常温(25℃±5℃)、干燥(相对湿度≤60%),存储期不超过12个月;运输过程需避免剧烈振动与潮湿,防止引脚氧化或电容体损坏。

五、选型与应用注意事项

  1. 电压降额:实际工作电压不得超过额定电压的70%(即≤112V),避免过压击穿;
  2. 纹波电流限制:实际纹波电流(100kHz下)不得超过1.02A,若纹波频率低于100kHz,耐受值会略有提升,但需参考厂商 datasheet;
  3. 安装布局:电容体需远离发热元件(如功率管),引脚焊接时避免受力变形,焊盘间距需匹配5mm引脚间距;
  4. 极性识别:铝电解电容为有极性电容,需严格按照正负极标识焊接,反接会导致电容损坏甚至爆炸。

总结:LKME2002C820MF是一款性价比突出的工业级中高压直插铝电解电容,以长寿命、高纹波耐受、紧凑体积为核心优势,适配多种工业设备的电源滤波与储能需求,是工业控制、电力电子领域的可靠选型。

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.
