LKME2502A221MF 直插铝电解电容产品概述
一、产品核心身份与品牌背景
LKME2502A221MF是永铭电子（Ymin） 推出的一款径向直插铝电解电容，属于工业级高可靠性电容系列。永铭作为国内专注铝电解电容研发生产的厂商，其产品广泛应用于电源、工业控制、通信等领域，以“宽温耐候、长寿命、高稳定性”为核心优势，符合RoHS环保标准及多项行业认证要求。
二、关键参数与规格明细
该电容的电气及物理参数清晰对应型号标识，具体如下：
类别 参数详情 说明 电气参数 容值：220μF（型号“221”对应22×10¹μF）精度：±20%
额定电压：100V
工作寿命：10000hrs@105℃ 容值精度满足多数工业场景需求；105℃高温下的长寿命设计是核心亮点 物理参数 封装：径向引线直插
电容体尺寸：D10mm（直径）×L25mm（长度）
脚间距：5mm
引线材质：镀锡铜 紧凑尺寸适配空间有限的PCB布局；5mm脚间距为标准直插规格，焊接兼容性强
三、性能与可靠性优势
宽温高寿命设计
10000小时的工作寿命（105℃环境下），得益于永铭优化的电解液配方及铝箔腐蚀工艺——减少高温下电解液干涸、氧化膜衰减，适合长期运行于高温工况（如电源内部、工业设备舱）。电气稳定性可靠
±20%的容值精度覆盖工业、消费电子的常规滤波/储能需求；100V额定电压可应对中高压场景（如220VAC电源的直流母线滤波），降额使用（建议≤80V）可进一步延长寿命。紧凑适配性
D10×L25mm的电容体体积小巧，径向引线结构比轴向引线更适合高密度PCB设计，5mm脚间距与多数插件焊盘兼容，无需特殊布局调整。环保与安全性
符合RoHS 2.0标准，无铅无镉；电容体采用阻燃外壳，焊接时不易起火，降低终端产品安全风险。
四、典型应用场景
该电容的参数特性使其适配多类中高压、高温环境的应用：
- 开关电源模块：作为输出滤波电容，稳定直流电压纹波（如LED驱动电源、适配器电源）；
- 工业控制设备：PLC、变频器、伺服驱动器的直流母线滤波/储能，耐温抗老化满足7×24小时运行；
- 家用电器：空调、洗衣机、油烟机的电源板滤波，适配家电内部的高温（如压缩机附近）；
- 通信基站电源：基站整流模块的辅助滤波，应对户外宽温（-40℃~85℃）环境；
- 医疗设备：小型医疗仪器的电源滤波（需确认医疗认证，部分场景可替代）。
五、选型与使用注意事项
- 电压降额：实际工作电压建议不超过额定电压的80%（即≤80V），避免过压导致电容快速衰减；
- 焊接规范：手工焊接温度≤260℃，时间≤10秒；波峰焊温度≤240℃，避免高温损坏电容体；
- 极性识别：铝电解电容有明确正负极（引线长度、外壳标识），需与PCB焊盘极性一致，反接会导致电容爆炸；
- 存储与运输：存储于常温（25℃±5℃）、干燥（湿度≤60%）环境，避免长期暴露在高湿度下导致引线氧化；
- 机械应力：焊接后禁止弯折引线，防止电容体开裂或内部电极损坏。
总结
LKME2502A221MF作为永铭的中高压直插铝电解电容，以“105℃/10000hrs长寿命、紧凑尺寸、稳定电气性能”为核心竞争力，覆盖工业、电源、家电等多领域需求，是替代进口同类产品的高性价比选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
