KCXE2002W270MF 铝电解电容产品概述

一、产品基本属性与核心参数

KCXE2002W270MF是Ymin(永铭)品牌推出的插件式铝电解电容,专为中高压电源场景设计,核心参数明确且适配工业级与消费级应用需求,具体如下:

项目 规格参数 产品类型 插件式铝电解电容 品牌型号 Ymin(永铭)KCXE2002W270MF 标称容值 27μF 容值精度 ±20% 额定电压 450V DC(直流额定电压) 封装尺寸 直径(D)10mm × 长度(L)20mm 引脚间距 5mm(标准插件间距) 环保标准 RoHS 2.0、REACH(无铅无有害物质)

二、关键性能指标详解

除核心参数外,产品的性能指标直接决定其在电路中的可靠性,结合同规格永铭电容的行业常规参数,关键性能如下:

  1. 纹波电流能力:120Hz(低频)下约0.4A,100kHz(高频)下约0.8A;需注意高温环境(如+105℃)需按10%~20%比例降额,避免纹波电流过载导致电容失效。
  2. 损耗角正切(tanδ):≤0.15(20℃、120Hz),低损耗特性可减少电源转换过程中的能量损耗,提升整体效率。
  3. 温度特性:工作温度范围为**-40℃~+105℃**,覆盖工业现场、户外设备等宽温环境需求,低温启动无容值骤降问题。
  4. 寿命特性:额定工况(+105℃、450V DC)下寿命为1000小时;若工作温度降至60℃,寿命可延长至约10000小时,适配长期稳定运行的场景。
  5. 漏电流:≤0.01CV(C=容值,V=额定电压),即20℃下充电3分钟后漏电流≤27μA,漏电流小可降低电源待机损耗。

三、典型应用场景

KCXE2002W270MF的高压、中等容值特性,使其适配以下核心场景:

  1. 开关电源模块:作为AC-DC转换电路的高压滤波电容,抑制整流后的电压纹波;或作为DC-DC升压电路的储能电容,稳定输出电压。
  2. LED驱动电源:适配高压LED串(如30-40颗串联)的驱动电路,过滤高频纹波,避免LED闪烁或光衰。
  3. 工业控制设备:PLC、变频器、伺服驱动器的电源滤波组件,耐温与可靠性满足工业现场的振动、温湿度要求。
  4. 家用电器:空调、洗衣机的变频控制板电源,适配家电内部的高温环境(如压缩机附近)。
  5. 通讯基站电源:辅助电源模块的滤波元件,支持基站设备的24小时连续运行。

四、封装与安装特性

产品的封装设计兼顾空间效率与安装便利性:

  1. 小型化封装:D10mm×L20mm的紧凑尺寸,比同容值高压电容节省约30%的PCB空间,适合高密度电路板布局。
  2. 引脚设计:镀锡铜引脚,焊接性优异(可通过波峰焊、手工焊),且耐腐蚀,避免引脚氧化导致接触不良。
  3. 安装兼容性:5mm引脚间距符合行业标准,PCB设计时无需特殊布线,可与同系列其他容值电容兼容替换。
  4. 极性标识:电容体侧面有清晰的负极标识,避免焊接时极性接反(电解电容极性接反会导致漏电流骤增、甚至爆炸)。

五、品牌与可靠性保障

Ymin(永铭)作为国内铝电解电容领域的主流品牌,KCXE2002W270MF通过多重可靠性验证:

  1. 高温寿命测试:在+105℃、额定电压下持续运行1000小时,容值变化≤±20%,tanδ变化≤50%,符合IEC 60384-1标准。
  2. 振动测试:通过2G/10-2000Hz的振动测试,满足工业设备的运输与运行振动要求。
  3. 环保合规:完全符合RoHS 2.0(无铅、无镉、无汞)与REACH法规,适配出口产品需求。
  4. 一致性控制:生产过程采用全自动卷绕、封装设备,容值、电压等参数一致性达99%以上,降低批量应用的选型风险。

总结

KCXE2002W270MF是一款高性价比的高压插件铝电解电容,兼具宽温特性、低损耗与小型化设计,可稳定适配开关电源、LED驱动、工业控制等多场景需求。其永铭品牌的可靠性保障,使其成为电源设计中替代进口电容的优质选择。

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
