  • 封装尺寸:电容体直径D=13mm,长度L=20mm(D13×L20mm),径向引线结构;
  • 品牌:艾华集团(AISHI),国内铝电解电容领域主流制造商。

二、关键性能指标详解

1. 电气性能

  • 额定电压400V:明确电容长期稳定工作的最大直流电压,避免过压损坏,简化中高压电路设计(无需串联低电压电容);
  • 容值精度±20%:K级精度覆盖工业级、消费电子等大部分应用,无需额外高精度匹配;
  • 铝电解特性:相比陶瓷电容具备更大容值密度,适合大电流滤波、储能需求。

2. 寿命与环境适应性

  • 工作寿命2000hrs@105℃:核心可靠性指标——在105℃高温下连续工作2000小时,容值变化≤±20%、损耗角正切值≤初始值150%,适配变频器、高温电源模块等高温工况;
  • 温度范围:结合寿命指标,可推断工作温度覆盖-40℃~105℃(具体以官方 datasheet 为准),满足宽温环境需求。

三、封装与物理特性

1. 封装结构

采用径向引线直插封装:电容体两端引出垂直于轴向的引线,便于电路板插件焊接,安装方式灵活(可垂直/水平安装)。

2. 物理尺寸

  • 电容体:D13mm×L20mm,常规中型规格,占用PCB空间适中,适配大多数插件孔位;
  • 引线:直插金属引线,焊接性良好,支持波峰焊、手工焊等常规工艺。

四、适用场景与应用优势

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
