KNSCHA 33μF/400V 直插铝电解电容(型号87EC0492)产品概述

一、产品基本定位

KNSCHA(科尼盛)87EC0492是一款直插式铝电解电容,专为中高压、紧凑空间场景设计,核心参数覆盖33μF容值、400V额定电压,兼顾宽温适应性与小体积封装,适用于工业电源、家电控制、照明驱动等多领域的滤波、储能环节,是高性价比的中高压铝电解解决方案。

二、核心性能参数解析

该电容的关键参数针对实际应用需求优化,具体如下:

  1. 容值与精度:标称容值33μF,精度±20%,满足工业级设备对容值稳定性的基本要求,无需额外高精度校准即可适配常规滤波场景;
  2. 额定电压与温域:额定电压400V,支持-25℃~+105℃宽温度范围,105℃高温环境下工作寿命达2000hrs,可适应高温、温差波动大的工作环境;
  3. 纹波与ESR表现:100kHz频率下纹波电流370mA,等效串联电阻(ESR)500mΩ——低ESR有助于降低高频损耗、抑制纹波干扰,适合开关电源等高频工作场景;
  4. 封装尺寸:电容体直径8mm、长度20mm,引脚间距3.5mm,小体积设计可有效节省PCB板空间,插件封装便于手工或自动焊接操作。

三、设计与工艺特点

  1. 铝箔与电解质优化:采用高纯度阳极铝箔,通过精密氧化工艺形成稳定氧化膜,保障400V高压下的绝缘可靠性;电解质配方适配高温环境,延缓电容老化速度,提升105℃下的寿命表现;
  2. 封装可靠性:电容外壳采用阻燃材料,符合电子设备安全标准;引脚镀锡处理,抗氧化性能优异,焊接时不易出现虚焊、假焊问题;
  3. 结构紧凑性:通过优化内部卷绕结构,在保持容值与耐压的前提下缩小体积,满足小型化设备的布局需求。

四、典型应用场景

87EC0492的参数特性使其适配多类场景:

  1. 工业电源系统:开关电源、线性电源的高压滤波与储能环节,400V额定电压可覆盖工业设备高压侧需求,宽温性能适应车间温差;
  2. 家电控制板:变频空调、滚筒洗衣机等家电的高压驱动电路,小体积封装适合紧凑的控制板布局,宽温范围满足家电日常工作环境;
  3. LED照明驱动:高压LED驱动电源的滤波模块,低ESR有助于降低驱动损耗,提升照明稳定性;
  4. 仪器仪表模块:测试仪器、医疗设备的高压子系统,稳定的容值与耐压性能保障测量精度。

五、可靠性与环境适应性

  1. 寿命验证:产品经过105℃高温老化测试,2000hrs寿命符合工业级设备的长期运行要求,实际使用中若控制电压降额(建议≤320V),寿命可进一步延长;
  2. 温湿度耐受:-25℃低温下容值变化率低,105℃高温下电解质无明显挥发,可适应户外设备或温差较大的应用场景;
  3. 安全合规:符合RoHS环保标准,无有害物质添加,适配全球市场的环保要求。

六、选型与使用注意事项

  1. 电压降额:实际工作电压建议不超过额定电压的80%(即320V以内),避免高压加速氧化膜老化,延长电容寿命;
  2. 纹波电流限制:工作时纹波电流需控制在370mA@100kHz以内,防止过热导致电解质干涸;
  3. 焊接工艺:手工焊接温度≤260℃,焊接时间≤5秒;自动焊接需符合插件电容焊接规范,避免损伤引脚与电容体;
  4. 环境放置:避免靠近热源(如功率器件),保持通风良好,防止局部高温加速老化。

该产品凭借高耐压、宽温域、小体积的综合优势,可满足多数中高压电子设备的滤波储能需求,是工业与消费电子领域的实用型铝电解电容解决方案。

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
