EHS2WM820M25OT 产品概述
一、产品简介
EHS2WM820M25OT 为艾华集团（AISHI）推出的一款高压直插式铝电解电容器，额定电压 450V，容值 82µF，公差 ±20%。电容体尺寸为直径 18mm、长度 25mm（D18×L25mm），采用传统插件（直插）封装，适用于要求高耐压、紧凑体积的开关电源、逆变器和工业电源滤波场合。器件为有极性电容，使用时须注意极性连接。
二、主要参数
- 容值：82µF
- 精度：±20%
- 额定电压：450V DC
- 封装/引脚形式：插件（直插、径向引出）
- 电容体尺寸：Φ18mm × L25mm
- 额定寿命：5000 小时 @ 105℃
三、关键特性与优势
- 高耐压设计：450V 额定电压可满足高压直流链路和高压滤波需求。
- 紧凑体积：18×25mm 的小外形，有利于在空间受限的电源板上实现高密度布局。
- 长寿命规格：在 105℃ 下经设计寿命为 5000 小时，适合要求较高可靠性的工业电源应用。
- 插件封装：便于手工焊接、波峰或选择性回流工艺装配，适配传统 PCB 装配流程。
四、应用场景
- 开关电源（高压滤波、直流总线）
- 工业逆变器与变频器
- 电机驱动和伺服电源
- 高频整流后端滤波与能量缓冲
- 电源模块样机开发与维修替换件
五、使用与选型建议
- 极性注意：本类铝电解电容有极性，使用时严禁反向施加直流电压。
- 温度与寿命：标称寿命为 5000hrs@105℃，长期可靠性建议在较低温度下使用或采取温度降额设计以延长寿命。
- 电压退让：为提高长期稳定性与寿命，建议根据具体应用考虑适度电压退让或选择更高额定电压/更大容量的方案。
- 纹波电流与 ESR：实际使用中应关注纹波电流和等效串联电阻（ESR），请以厂家完整数据表为准以匹配散热和纹波能力。
- 安装方向：尽量按照 PCB 设计要求确定安装方向，避免长期在高温及不利散热位置使用。
六、储存与装配注意事项
- 储存环境宜干燥、常温并避光，避免高湿、高温和腐蚀性气体。
- 焊接温度和时间应符合工艺规范，避免过热导致电解液劣化。
- 运输与手工搬运时避免强烈振动、压迫电容体或引脚。
七、可靠性与售前确认
EHS2WM820M25OT 适合多数高压直流滤波与能量储存场合，但在关键或特殊环境（如高频脉冲、大纹波、高海拔或需长寿命 1 万小时以上）应用前，建议与供应商确认详细的电气参数（如 ESR、纹波电流、耐振动等）与认证信息，并进行必要的样品测试验证。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
