VKME1651J331MV是永铭(Ymin)品牌推出的贴片型铝电解电容,针对中低压滤波、高频纹波抑制场景设计,核心参数清晰明确,覆盖了工业、汽车、通信等领域的典型需求:
330μF±20%的容值精度,满足大多数工业、通信设备的滤波误差要求——无需额外校准即可稳定工作,适配对容量一致性要求不苛刻但需稳定滤波的场景(如电源输出端滤波)。
63V额定直流电压,适用于12V、24V、48V等中低压电源系统,留有1.5倍以上安全余量(避免瞬态过压损坏),可支撑开关电源、DC-DC转换器等电路的正常运行。
100kHz下1.58A的纹波电流能力是核心亮点:开关电源、高频逆变器等电路会产生大量高频纹波,该电容可有效吸收纹波能量,将输出电压波动控制在合理范围,提升负载端(如MCU、传感器)的工作稳定性。
-55℃~+105℃的工作温度范围,覆盖了极端低温(如寒冷地区户外设备) 和高温(如电源模块内部发热) 场景;高低温下容值衰减率控制在行业标准内(-55℃时容值衰减≤10%,105℃时衰减≤20%),避免因温度变化导致滤波性能下降。
10000小时@105℃的额定寿命,意味着在高温环境下连续运行3年以上仍能保持性能(实际寿命随温度降低呈指数级延长:25℃下寿命可达50000小时以上),可降低设备长期维护成本。
该电容采用SMD贴片封装,电容体尺寸为直径10mm×长度16.5mm,引脚间距符合国际标准贴片电容规范,具备以下优势:
VKME1651J331MV的参数特性使其适用于以下高需求场景:
如PLC(可编程逻辑控制器)电源、伺服驱动器电源——需63V以下中低压滤波,高频纹波抑制需求明确,宽温范围匹配工厂车间(0℃~50℃)的环境变化。
车载信息娱乐系统、车身控制器的电源滤波——宽温范围(-40℃~85℃)匹配车载环境,长寿命(10000小时@105℃)满足汽车10年以上使用周期要求,振动测试符合IATF16949标准。
基站电源、光纤收发器的滤波电容——7×24小时不间断运行,长寿命设计可支撑设备5年以上免维护,高频纹波抑制能力提升信号传输稳定性。
高端充电器、智能家电的电源模块——贴片封装适合批量生产,容值与耐压满足快充(65W以上)、大功率电源的滤波需求,宽温范围适配家庭环境(-10℃~40℃)。
永铭(Ymin)是国内铝电解电容领域的主流品牌,产品通过ISO9001、IATF16949等质量体系认证,VKME1651J331MV经过以下严格测试:
综上,VKME1651J331MV是一款性价比高、可靠性强的贴片铝电解电容,兼顾了容量、耐压、高频性能与环境适应性,适合工业、汽车、通信等多领域的中低压滤波场景。
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.
