87EC0497 直插铝电解电容产品概述

一、产品基本定位

87EC0497是KNSCHA(科尼盛)推出的中高压直插铝电解电容,针对工业级电子设备的滤波、储能需求设计,兼顾高耐压、实用纹波能力与紧凑体积,适配多数中功率电路的高压直流场景,无需过度降额即可稳定工作。

二、核心电气参数详解

该电容的关键指标明确且匹配工业应用需求,具体如下:

  • 容量与精度:标称容量39μF,±20%精度范围,满足常规滤波电路对容量偏差的容忍度,避免因容量波动影响电路性能;
  • 额定电压:400V直流额定电压,适配220V交流整流后的高压直流系统(220VAC整流峰值约311V),留有充足安全裕量,降低过压击穿风险;
  • 纹波与ESR:100kHz频率下,纹波电流能力达435mA,等效串联电阻(ESR)为500mΩ——低ESR可减少自身热损耗,同时有效抑制高频纹波干扰,提升电路输出稳定性;
  • 温度与寿命:工作温度范围覆盖-25℃至+105℃,在105℃高温工况下额定寿命为2000小时,符合工业设备对极端温度环境的可靠性要求。

三、机械与封装规格

87EC0497采用插件式封装,机械尺寸紧凑,适配常规PCB布局:

  • 电容体直径(D)10mm,长度(L)18mm,体积小巧,适合密集布线的电路板;
  • 引脚间距5mm,适配手工焊接或自动插件工艺,兼容性强,无需特殊工装即可安装。

四、工作特性与可靠性

该电容设计重点突出高可靠性与场景适配性:

  1. 高压裕量充足:400V额定电压远高于220V交流整流后的峰值电压,避免过压击穿,适合长期连续工作;
  2. 高温稳定性:105℃高温下仍保持2000小时额定寿命,可应对工业设备内部的高温工况(如变频器、电源模块);
  3. 纹波抑制能力:100kHz下的435mA纹波电流与500mΩ ESR,能有效滤除开关电源、变频器等设备中的高频纹波,减少对敏感电路的干扰;
  4. 抗老化性能:采用科尼盛成熟的铝电解电容制造工艺,降低鼓包、漏液等常见失效概率,延长设备整体使用寿命。

五、典型应用场景

87EC0497的参数特性使其适配以下主流场景:

  • 开关电源:220VAC输入的开关电源前级/后级高压滤波,提升输出电压稳定性;
  • 变频器与伺服驱动器:直流母线滤波,抑制母线纹波波动,保障电机控制精度;
  • 工业控制设备:PLC、传感器模块的电源稳压滤波,稳定核心电路供电;
  • 高压照明驱动:部分高压LED驱动电源的储能滤波环节;
  • 家电变频模块:高端洗衣机、空调的变频控制板滤波,适配高压直流环境。

六、品牌与选型价值

KNSCHA(科尼盛)作为国内铝电解电容领域的成熟厂商,87EC0497具备以下选型优势:

  • 参数匹配性:无需额外降额即可适配多数中功率高压电路,简化设计流程;
  • 环保合规:符合RoHS等国际环保标准,满足出口与国内工业设备的环保要求;
  • 成本平衡:性能与价格比优异,适合批量采购的工业客户,降低整体BOM成本;
  • 售后支持:提供常规技术支持与产品质保,保障客户使用过程中的问题解决。

综上,87EC0497是一款性价比突出的中高压直插铝电解电容,可满足多数工业与民用设备的高压滤波、储能需求。

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.

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
