  • 额定电压:80V,可稳定承载中高压电路环境,避免过压击穿风险;
  • 高频纹波能力:100kHz测试条件下,最大纹波电流为1.04A,能够有效抑制开关电源、DC/DC转换器等高频电路中的纹波干扰,保障输出电压的稳定性。

二、封装与物理尺寸

VKML1451K221MV采用表面贴装(SMD)封装,物理尺寸清晰:

  • 电容体直径12.5mm,长度14.5mm,封装标注为12.5×14.5mm;
  • 贴片封装适配自动化回流焊工艺,无需手工焊接,提升生产效率,同时节省电路空间,适合高密度PCB设计;
  • 封装尺寸符合行业标准,可与同类规格电容互换,降低设计兼容性成本。

三、性能特点

该电容的核心性能优势聚焦于环境适应性与长期可靠性:

  1. 宽温工作范围:支持-55℃至+105℃的工作温度区间,覆盖低温(如北方户外设备、低温存储场景)和高温(如密闭机箱、高功率设备内部)环境,无需降额使用即可稳定运行;
  2. 长寿命设计:在105℃高温环境下可连续工作10000小时,远高于普通电解电容的寿命标准,适合7×24小时持续运行的工业设备、通信基站等场景,减少维护频次与成本;
  3. 高频纹波承载:针对高频电路优化,100kHz下1.04A的纹波电流能力,可有效降低开关电源输出的电压波动,提升负载设备的工作稳定性;
  4. 品牌品质保障:由永铭(Ymin)品牌生产,该品牌在铝电解电容领域具备成熟的电解液配方与生产工艺,产品一致性好,可靠性经行业多年验证。

四、适用应用场景

基于参数与性能,VKML1451K221MV可广泛应用于以下领域:

  • 开关电源:AC/DC电源适配器、DC/DC转换器的输出滤波环节,抑制高频纹波;
  • 工业控制:PLC、伺服驱动器、变频器等设备的电源滤波,适应工业现场的高低温与振动环境;
  • 通信设备:基站、路由器、交换机等设备的电源模块,长寿命设计满足7×24小时运行需求;
  • 消费电子:LED驱动电源、平板电视、显示器等设备的电源滤波电路;
  • 车载周边:车载充电器、车载显示屏、行车记录仪等设备的电源滤波,适应汽车内部的温度变化与振动环境。

五、可靠性与环境适应性

该电容的可靠性体现在多维度:

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
