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。
该型号属于艾华通用铝电解电容系列,型号命名逻辑清晰:
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。
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)。
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。
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。
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℃)。
该型号采用插件式封装,物理尺寸符合国际标准:
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。
结合参数特性,该型号适用于以下核心场景:
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
