VKME1451J221MV 贴片铝电解电容产品概述

一、产品核心身份与定位

VKME1451J221MV是永铭电子(Ymin) 推出的一款工业级贴片铝电解电容,针对电源滤波、储能场景设计,兼具高纹波电流能力、宽温适应性与长寿命特性,是替代传统引线电容、提升电路集成度的优选元件,广泛适配工业控制、通信、消费电子等领域。

二、关键性能参数深度解析

该电容的核心参数直接决定应用边界,具体如下:

  1. 容值与精度:标称220μF,精度±20%——满足大多数滤波电路对容值偏差的常规要求,无需额外高精度补偿,降低设计成本。
  2. 额定电压:63V直流(DC)——可稳定承载中低压电源系统的工作电压,预留一定过压裕量(需避免长期超额定值)。
  3. 纹波电流能力:1.2A(有效值,@100kHz频率)——高频纹波抑制能力突出,适配开关电源等高频噪声环境,减少输出电压波动。
  4. 尺寸与封装:电容体直径10mm、长度14.5mm,SMD贴片封装(10×14.5mm规格)——表面贴装兼容自动化生产,紧凑尺寸提升PCB布局密度,适配小型化设备需求。
  5. 寿命与温度:10000小时(@105℃高温),工作温度-55℃~+105℃——高温工况下寿命稳定,宽温覆盖低温启动与高温持续工作,满足工业级极端环境要求。

三、封装与设计特性

  1. SMD贴片优势:无长引线设计,减少寄生电感/电阻,提升高频性能;兼容回流焊、波峰焊工艺,适配大规模自动化生产,降低人工成本。
  2. 结构可靠性:采用铝电解经典结构(阳极箔+阴极箔+优化电解液+隔膜)——电解液配方减少高温干涸风险,阳极箔高比容设计实现220μF大容量在紧凑尺寸内集成。
  3. 引脚可靠性:贴片引脚采用抗腐蚀材料,焊接牢固性好,避免虚焊导致的电路故障,提升整机稳定性。

四、典型应用场景

结合参数特性,该电容适用于以下核心场景:

  1. 开关电源(SMPS):AC-DC、DC-DC转换器的输出滤波环节——高纹波电流抑制高频噪声,稳定输出电压。
  2. 工业控制设备:PLC、伺服驱动器、变频器的电源模块——宽温适配车间高低温环境,长寿命减少维护频次。
  3. 通信设备:基站、路由器、交换机的电源滤波——稳定容值与纹波抑制保障信号传输质量。
  4. 高端消费电子:变频空调、洗衣机、高端电视的电源部分——高温环境下(如压缩机附近)持续工作,寿命可靠。
  5. 汽车电子(辅助场景):车载电源、仪表盘电路(需补充车规验证)——宽温适配汽车低温启动与高温暴晒环境。

五、可靠性与品质保障

永铭电子对该产品实施严格质量管控:

  1. 可靠性测试:通过105℃高温寿命测试(10000小时)、-55℃~105℃温度循环测试、85℃/85%RH湿度测试等,验证产品稳定性。
  2. 环保合规:符合RoHS2.0、REACH标准,无有害物质,适配全球市场需求。
  3. 品牌背书:永铭作为国内铝电解电容龙头企业,产品广泛应用于工业、通信领域,质量体系通过ISO9001、IATF16949认证。

六、选型与使用注意事项

  1. 电压匹配:电路工作电压需低于63V,避免过压击穿电容。
  2. 温度降额:若环境温度超过105℃,需将电压/纹波电流降额至80%以下使用。
  3. 焊接工艺:遵循回流焊温度曲线(峰值230℃~250℃,时间≤10秒),避免过热损坏电容。

总结

VKME1451J221MV以高纹波电流、宽温长寿命、紧凑贴片封装为核心优势,是中低压电源滤波、储能场景的高性价比选择,适配多领域设备的小型化、高可靠性需求。

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
