VKMD1451H221MV 贴片铝电解电容产品概述

VKMD1451H221MV是永铭(Ymin)推出的一款工业级贴片铝电解电容,专为中高压、高频纹波抑制场景设计,凭借宽温适应性、长寿命和紧凑型封装,成为工控、车载、通信等领域的常用选型。

一、产品基本信息

该型号属于SMD(表面贴装)封装铝电解电容,核心定位工业级,符合电容行业通用可靠性标准。型号命名中:

  • “VKMD”为永铭该系列电容代号;
  • “221”代表标称容值220uF(22×10¹uF);
  • “H”标识高温适配特性;
  • 整体设计兼顾性能与成本,适合批量应用场景。

二、关键电气参数解析

(1)容值与精度

标称容值220uF,精度±20%,满足大多数工业电路对电容容量的偏差要求,无需额外高精度筛选,降低采购与生产环节的成本。

(2)额定电压

直流额定电压50V,可稳定承载50V以下的工作电压,避免过压击穿风险,适配24V、48V等中低压工控电源系统。

(3)纹波电流能力

100kHz频率下可承受1.19A纹波电流——这是衡量电容高频性能的核心指标:纹波电流会导致电容发热,该参数意味着在开关电源等高频场景中,能有效抑制温度上升,减少因热老化导致的性能衰减。

(4)频率特性

明确标注100kHz下的纹波电流,说明产品针对高频场景优化,避免了普通低频电容在高频下性能骤降的问题,适配DC-DC转换器、高频开关电源等应用。

三、物理尺寸与封装特点

  • 封装类型:SMD表面贴装,兼容自动化贴片生产线,无需手工焊接,提升批量生产效率;
  • 具体尺寸:电容体直径8mm(D8)、长度14.5mm(L14.5),属于紧凑型贴片尺寸,在PCB布局中占用空间小,尤其适合车载中控、手持工控终端等小型化设备;
  • 引脚设计:采用标准SMD引脚,焊接可靠性高,抗振动性能优于插件电容,适合车载等振动环境。

四、环境适应性与寿命表现

(1)工作温度范围

-55℃至+105℃,覆盖工业级与部分车载级温度需求:

  • 低温场景:可稳定工作于-55℃(如北方户外工控设备);
  • 高温场景:105℃下连续工作无性能衰减(如高温车间的电源模块)。

(2)工作寿命

10000小时@105℃,这是行业通用的寿命测试标准(105℃下连续工作时长)。换算成常温(25℃)下,寿命可达数万小时,满足7×24小时运行的设备需求(如基站电源、工业PLC),降低设备维护成本。

五、典型应用场景

结合产品参数,VKMD1451H221MV的主要应用场景包括:

  1. 开关电源模块:AC-DC、DC-DC转换器的滤波电容,高频纹波抑制能力匹配100kHz场景;
  2. 工业控制设备:PLC、伺服驱动器、变频器的电源滤波电路,宽温适应性适配工厂车间温度变化;
  3. 车载电子单元:车载充电器、中控系统、仪表盘的辅助电源,紧凑型尺寸适合车内狭小空间;
  4. 通信设备:基站电源、路由器、交换机的滤波电容,长寿命满足7×24小时运行要求;
  5. 小型化设备:手持工控终端、便携式医疗仪器的电源滤波(需确认医疗认证,永铭部分型号有对应资质)。

六、核心优势总结

  1. 宽温稳定:-55105℃工作范围,比普通民用电容(-2585℃)更耐极端温度;
  2. 高频抗纹波:100kHz下1.19A纹波电流,适配开关电源等高频场景,减少发热;
  3. 长寿命设计:10000hrs@105℃,降低设备维护频次;
  4. 紧凑型封装:8×14.5mm SMD尺寸,节省PCB空间,支持小型化设计;
  5. 工业级可靠性:永铭品牌批量测试验证,适合对可靠性要求高的场景。

选型补充建议

若需适配更高电压(如63V)或更大纹波电流(如1.5A@100kHz),可参考永铭同系列其他型号;若对容值精度要求更高(如±10%),需提前确认对应规格的 availability。

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
