VKMD1001E221MV是永铭(Ymin)针对中高压、长寿命、高频滤波场景推出的片式铝电解电容,主打工业控制、汽车电子及小型化消费电子领域的电源系统优化,兼顾紧凑尺寸与高可靠性,是替代传统插件电解的贴片化优选方案,可直接兼容自动化生产流程,降低设备集成成本。
标称容值220μF,±20%的精度范围,满足多数电路对滤波、储能的基础需求:无需额外并联电容即可覆盖5V-24V电源系统的电压波动抑制,同时预留容值裕量应对长期使用中的轻微衰减。
25V直流额定电压,适配主流低压电源(如12V工业电源、24V车载电源),避免过压击穿风险;若系统实际工作电压低于20V,可进一步提升安全裕量,延长使用寿命。
660mA(@100kHz)的纹波电流额定值,针对开关电源高频噪声(典型频率100kHz左右)具有高效抑制效果:可将电源输出纹波电压控制在50mV以内,提升电路稳定性(如PLC模拟量输入精度、车载音响信号纯度)。
结合铝电解电容的损耗角正切(tanδ)特性,在10kHz-100kHz工作频率范围内保持低损耗(典型值≤0.12),减少自身发热,进一步降低对周边器件的热干扰。
采用SMD表面贴装封装,电容体尺寸为直径8mm×长度10mm,属于小型化片式电解范畴:
10000小时@105℃的工作寿命,是普通片式电解的2-3倍:可满足工业设备7×24小时连续运行(如PLC、变频器)的长期可靠性要求,若工作温度为85℃,寿命可延长至30000小时以上,降低运维成本。
-55℃至+105℃的温度区间,覆盖全球多数应用场景:
采用抗老化电解液及双层密封结构,可有效防止电解液干涸、电容值衰减:长期使用后容值衰减率≤10%(10000小时@105℃),远优于行业标准(≤20%)。
PLC(可编程逻辑控制器)、伺服驱动器、变频器的电源滤波模块:利用宽温、长寿命特性适应工业现场的高低温及连续运行需求,避免因电容失效导致设备停机。
车载中控系统、传感器模块、LED车灯驱动电源:满足汽车-40℃至+85℃的工作温区要求,同时应对发动机舱的高温振动环境,提升车载电子的可靠性。
路由器、机顶盒、智能音箱的电源滤波电路:紧凑尺寸适配小型化设备,高频纹波抑制能力提升信号稳定性(如WiFi信号传输无干扰)。
小型基站、光纤收发器的电源模块:宽温与长寿命特性适应户外通信设备的环境变化,减少户外基站的维护频次。
VKMD1001E221MV通过平衡电气性能、尺寸与可靠性,成为多领域电源系统优化的实用选择,尤其适合对长寿命、宽温及高频滤波有明确需求的场景。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
