LKMC0901H470MF是永铭(Ymin)品牌推出的径向直插铝电解电容,属于小型化、中低压通用型产品。型号中:
该产品核心定位是满足紧凑空间、中等纹波抑制、高温可靠性需求的电路设计,覆盖消费电子、工业辅助电路等场景。
标称容值47μF,精度公差±20%,符合铝电解电容常规精度要求,可满足大多数滤波、耦合、旁路电路的容量匹配需求,无需额外高精度校准。
额定电压50V DC,为电容安全工作电压上限。使用时需确保电路电压不超过该值,避免过压导致电容击穿、漏液或容量快速衰减。
在100kHz高频条件下:
低ESR有助于抑制输出纹波噪声,同时减少电容发热延长寿命,该参数使产品适配开关电源等高频纹波环境。
采用径向引线直插封装(插件式),引脚为镀锡铜质材料,焊接兼容性好,支持手工或自动焊接,适配传统PCB板设计。
小型化设计可有效节省PCB布局空间,适配小家电、通信模块等紧凑设备的内部结构需求。
产品为有极性电解电容(铝电解常规特性),本体标注负极标识(如白色条纹),焊接时需严格按极性安装,反接会导致电容损坏或性能失效。
在105℃高温环境下,工作寿命可达9000小时,属于中长寿命规格。该参数表明电容在高温工况(如设备内部散热不良、夏季高温环境)下仍能稳定工作,可靠性优于普通常温寿命电容。
永铭采用优化的电解液配方(低挥发、高稳定性)和铝箔结构(增大有效面积),可减少长期工作中的容量衰减(≤20%/9000hrs@105℃)和漏液风险;电容本体采用阻燃外壳,符合安全标准,降低设备故障隐患。
结合高温寿命参数,推测产品工作温度范围为**-40℃至+105℃**,可覆盖大多数民用、工业级设备的环境温度要求(如冬季低温、夏季高温环境)。
综上,LKMC0901H470MF是一款小型化、高频适配、高温可靠的通用直插铝电解电容,适合多场景电路设计需求,是平衡性能与成本的优选方案。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
