(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。)

三、结构与机械特性

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。

四、可靠性与寿命

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。

五、典型应用场景

  • 开关电源的输出滤波与能量存储
  • 工业电源与驱动设备的高压直流滤波
  • 测试仪器与测控设备中的去耦与稳定电压源
  • 电源模块、伺服驱动器、逆变器中的高压支路
  • 需要通过孔插件安装且对体积有要求的高压电路

六、选型与使用建议

  • 电压降额:在高温或连续高纹波工况下,建议适度降额使用以延长寿命。
  • 温度管理:尽量减小电容周围热源与通风不良导致的工作温升。
  • 极性注意:为铝电解电容,安装时必须正确区分正负极,严禁反向施加直流电压。
  • 焊接与加工:遵循厂商推荐的波峰/手工焊接工艺与加热条件,避免过热损伤密封结构。
  • 储存:储存环境应干燥、避免高温、避免长时间暴露于潮湿环境,必要时按厂方建议进行预处理。

七、采购与技术支持

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。

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
