LKMB0901E2R2MF 直插铝电解电容产品概述

LKMB0901E2R2MF是永铭(Ymin)品牌推出的径向直插铝电解电容,定位于通用型小型化电解电容,凭借紧凑尺寸、可靠高温寿命,广泛适配消费电子、工业控制等领域的电源滤波、耦合等基础电路需求。

一、产品核心身份与定位

该型号明确对应25V/2.2μF±20% 直插铝电解电容,采用径向引线封装(尺寸5×9mm),是永铭针对小型化电路设计的经济型产品,兼顾性能可靠性与成本控制,适合大多数无需高精度电解电容的通用场景。

二、关键参数详解

1. 电气核心参数

  • 容值与精度:2.2μF(微法),精度±20%——电解电容商业级标准精度,可满足滤波、耦合、旁路等基础电路需求,无需额外高精度设计,降低成本;
  • 额定电压:25V(直流)——电容长期工作的最大直流电压,实际使用需注意:交流纹波电压峰值不超额定电压80%(即20V以内),避免纹波过压加速老化;
  • 工作寿命:7000小时@105℃——核心亮点:电解电容寿命随温度降低呈指数级延长(每降10℃寿命翻倍),常温(25℃)下理论寿命超180万小时,长期可靠性有保障。

2. 尺寸与引脚参数

  • 电容体尺寸:直径5mm,长度9mm——小型化电解电容范畴,同类25V/2.2μF产品中体积紧凑,节省电路板空间;
  • 引脚间距:2mm——符合主流PCB插件焊盘规范,焊接兼容性强,无需特殊定制焊盘。

三、封装与设计特点

1. 径向引线封装

采用径向引线封装(引脚从电容体两端垂直引出),相比轴向封装布局更灵活,适合PCB板密集布局;封装尺寸5×9mm(直径×长度),直接匹配小型化电路空间需求。

2. 引脚可靠性

引脚采用镀锡工艺,焊接附着力强,不易虚焊;引脚长度适配常规插件设备,人工/自动化插件均无压力。

四、典型应用场景

  1. 消费电子:小型家电(电动牙刷、加湿器、智能台灯)电源模块滤波——2.2μF滤除中低频杂波,稳定电机/LED驱动电压;
  2. 工业控制:小型PLC、传感器模块低频去耦——配合陶瓷电容实现宽频滤波,减少信号干扰;
  3. LED驱动电源:低压LED灯带、小功率LED灯具驱动电路滤波——25V满足低压需求,2.2μF适配纹波抑制;
  4. 通信终端:路由器、无线模块电源辅助滤波——小型化体积集成到紧凑通信设备内部。

五、选型与使用注意事项

  1. 极性确认:铝电解电容为有极性电容,安装需严格匹配PCB正负极标识(电容体标注负极条纹),反接会导致失效甚至爆炸;
  2. 电压余量:实际工作电压建议低于20V(额定电压80%),高温环境(近105℃)需进一步降额;
  3. 焊接规范:焊接温度≤260℃,时间≤3秒,避免高温损伤电解液;
  4. 存储条件:未使用电容存于-40℃~+85℃、湿度≤60%环境,避免阳光直射或腐蚀性气体。

六、产品优势总结

  1. 高温可靠性:7000小时@105℃寿命优于同类经济型电容,适合高温/长期运行电路;
  2. 小型化设计:5×9mm紧凑体积,适配电子设备小型化趋势;
  3. 性价比突出:商业级精度满足通用需求,成本低于高精度电容;
  4. 兼容性强:2mm引脚间距符合主流PCB规范,焊接布局无额外成本。

综上,LKMB0901E2R2MF是高性价比、小型化、可靠耐用的通用直插铝电解电容,是电源滤波、耦合电路的首选元件之一。

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
