LKMD0901H121MF 直插铝电解电容产品概述
一、产品基本信息
LKMD0901H121MF是永铭（Ymin）品牌推出的径向引线直插铝电解电容，属于通用型电解电容范畴，主要用于电子电路的滤波、储能及纹波抑制。该型号采用标准径向插件封装，适配传统通孔焊接工艺的PCB布局，符合工业级元器件的基本设计规范。
二、核心电气参数
该电容的参数覆盖中等功率设备的常见需求，关键性能如下：
- 容值与精度：标称120μF，精度±20%，满足多数滤波电路的容值偏差要求；
- 额定电压：50V直流，为安全工作电压上限，实际建议降额至40V以内（长期工作），避免过压衰减性能；
- 纹波电流耐受：800mA（有效值）@100kHz，可应对开关电源等高频纹波场景；
- 等效串联电阻（ESR）：180mΩ@100kHz，低ESR有助于减少损耗发热，提升纹波抑制效果。
三、物理封装与尺寸
采用径向引线封装，尺寸紧凑适配小型化设计：
- 电容体：直径8mm×长度9mm（D8×L9mm，不含引脚）；
- 引脚间距：3.5mm（通孔中心距）；
- 引脚长度：常规插件长度（10-12mm，适配标准PCB板厚）。
四、可靠性与工作寿命
该电容可靠性突出，工作寿命10000小时@105℃，即105℃高温下可稳定运行10000小时，属于工业级电解电容的较高寿命等级，适合高温、高负荷场景（如工业控制设备）。
五、典型应用场景
结合参数与可靠性，适用于以下场景：
- 开关电源：滤波抑制高频纹波，提升输出稳定性；
- LED驱动电源：储能与滤波，满足LED驱动需求；
- 工业控制板：适配工业环境的高温、高负荷要求；
- 消费电子：机顶盒、路由器、小型家电（电饭煲、微波炉控制板）等；
- 汽车电子辅助电路：非关键高温区域（仪表盘、中控）的滤波/储能。
六、使用注意事项
为保障性能与寿命，需注意：
- 电压降额：长期工作电压≤40V（额定值的80%）；
- 焊接规范：波峰焊≤260℃（10秒内），手工焊≤350℃（3秒内）；
- 储存环境：-40℃~+85℃、湿度≤60%，避免电解液干涸；
- 机械应力：安装时避免引脚过度弯曲，防止电容体损坏。
该型号以平衡的电气性能、紧凑尺寸及高温可靠性，成为中等功率设备通用滤波/储能的优选元件。

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.
