EWH1KM221K20OT 是艾华集团(AISHI)推出的一款直插式铝电解电容,额定容量为 220µF,额定电压 100V,容差 ±20%。该器件采用插件(radial lead)封装,电容体直径 D=13mm、长度 L=20mm,脚间距 5mm,设计用于对体积有严格限制且需要较高工作电压的工业与电源类应用。产品标称寿命为 2000 小时(@105℃),适合要求较高温度耐受性的场合。
(注:详细电气参数如漏电流、等效串联电阻(ESR)、额定纹波电流等请参阅厂商数据手册或向供应商索取测量报告。)
EWH1KM221K20OT 采用铝箔/电解质结构,金属外壳并经密封处理以保证长期稳定性。直插引脚方便通过孔式 PCB 安装,5mm 的脚间距适配常规紧凑电路板布局。D13×L20mm 的小体积在保证较高耐压的同时,便于在受限空间内实现高电压滤波或能量缓冲。
本品在高温条件下的寿命试验为 2000 小时 @ 105℃,表明其在高温工况下具有较好的工作稳定性。为延长实际使用寿命,建议在系统设计中考虑降额使用(即不过度靠近额定电压与最高温度),并关注实际纹波电流与环境温度对寿命的影响。常见可靠性考量包括:高温老化、低温启动性能、振动与冲击耐受、以及电解质老化导致的容量衰减与 ESR 上升。
如需样品测试或批量采购,请提供型号 EWH1KM221K20OT、所需数量及使用场景给供应商或艾华集团授权代理商,以便获取完整的规格书、可靠性报告与可追溯的出厂检验数据。对特殊工况(如极高纹波电流、低温启动或苛刻机械振动)有进一步要求时,建议与技术支持沟通,以确认该型号能满足目标应用或推荐替代系列。
总结:EWH1KM221K20OT 以其 100V 高压等级、220µF 的容量组合和小巧的 D13xL20mm 插件封装,适合用于对体积与耐压都有较高要求的工业与电源应用。合理的降额使用与良好的温度管理将有助于发挥其长期可靠性。

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.
