EWH1HM220D11OT 直插铝电解电容产品概述

EWH1HM220D11OT是艾华集团(AISHI)推出的通用型直插铝电解电容,针对中低压电路的滤波、耦合、旁路等核心需求设计,兼顾性能可靠性与成本优势,适用于多数工业控制、家电及小型电子设备场景。

一、产品基本定位与核心身份

该型号属于艾华通用铝电解电容系列,型号命名逻辑清晰:

  • “EWH”为系列代码(对应中低压通用型);
  • “1H”标识额定电压50V;
  • “M220”表示标称容值22μF(±20%精度);
  • “D11”明确电容体直径5mm、长度11mm;
  • “OT”为封装及衍生参数(直插式)。

作为直插设计,无需特殊焊接工艺,兼容手工/波峰焊接,是替代进口同规格电容的高性价比选择。

二、关键电气参数详解

(1)容值与精度

标称容值22μF,精度±20%,符合工业级通用电容的典型要求,可满足多数滤波、耦合电路的容量偏差需求(无需高精度场景的特殊选型)。

(2)额定电压与安全余量

额定电压50V DC,高于常见12V、24V、48V电路的工作电压,预留1.2-1.5倍安全余量(行业常规设计标准),有效降低过压损坏风险,延长使用寿命。

(3)纹波电流耐受能力

120Hz频率下最大纹波电流65mA,对应50/60Hz市电环境的纹波抑制需求(多数电源电路纹波频率集中在100/120Hz),可稳定吸收开关电源输出端的纹波噪声,保证供电质量。

(4)高温工作寿命

2000小时@105℃,是核心可靠性指标:在105℃高温环境(如密闭电源盒、工业高温区)下,仍能稳定工作2000小时以上,优于普通电容(多为1000小时@105℃)。

三、封装与物理尺寸规范

该型号采用插件式封装,物理尺寸符合国际标准:

  • 电容体直径(D):5mm(小型化设计,节省PCB空间);
  • 电容体长度(L):11mm(不含引脚);
  • 引脚间距(P):2mm(标准插件间距,兼容多数PCB焊盘);
  • 引脚长度:约5mm(便于焊接与固定)。

可直接替换同规格(50V/22μF/±20%/D5xL11)的其他品牌电容,无需调整PCB布局。

四、性能特性与可靠性优势

  1. 高温稳定性:105℃下寿命表现优异,适合工业高温场景(如变频器、电机控制器);
  2. 纹波抑制:65mA@120Hz纹波电流能力,降低电源输出纹波,提升电路信噪比;
  3. 容量稳定:-40℃~+105℃范围内容值变化率符合行业标准,避免温度波动导致电路性能波动;
  4. 耐湿性:防潮封装工艺,适应高湿度环境(如南方地区、户外辅助电路),减少漏液失效风险。

五、典型应用场景

结合参数特性,该型号适用于以下核心场景:

  1. 开关电源滤波:小功率开关电源(5V/12V/24V)输出端滤波,吸收高频纹波;
  2. 工业控制:PLC模块、电机驱动板直流母线滤波,承受温度应力;
  3. 音频耦合:小型音箱、功放信号耦合,保证音频传输稳定;
  4. 家电控制板:洗衣机、空调电源滤波,满足家电长期使用需求;
  5. 车载辅助电路:车载充电器、中控屏辅助电源滤波(需确认温度匹配)。

六、品牌与质量保障

艾华集团是国内铝电解电容龙头,产品通过ISO 9001、ISO/TS 16949认证,符合RoHS、REACH环保标准。EWH1HM220D11OT经多轮可靠性测试(高温寿命、纹波电流、温度循环等),批量一致性稳定,为客户提供可靠供应链支持。

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
