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。
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:
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。
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。
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。
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。
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。
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。
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)。
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。
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。
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。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
