VKME1451H331MV是永铭电子(Ymin) 推出的一款中高压贴片铝电解电容,属于通用型滤波/储能器件,主打小型化、宽温适应性、长寿命三大核心优势,适配工业控制、通信设备、消费电子等对可靠性有要求的场景。永铭作为国内电解电容领域的主流品牌,其产品以“性能稳定+成本可控”著称,这款型号是其贴片电解系列中的经典款之一。
标称容值为330μF(型号中“331”为容值编码,代表33×10¹μF),精度±20%——符合铝电解电容的常规精度标准,无需额外高精度匹配,可满足多数电路对滤波、储能的误差需求。
直流额定电压50V,实际工作电压建议控制在额定值的80%以内(即≤40V),避免过压导致电容老化加速或击穿,适配中等功率电路的电压范围。
在额定工作条件下,容值衰减速率、漏电流等参数符合行业标准,长期运行中性能波动小,可降低设备故障风险。
采用SMD(表面贴装)封装,适配自动化SMT生产线,无需手工焊接,生产效率高,适合批量制造。
电容体直径10mm,长度14.5mm(D10×L14.5mm),属于紧凑型贴片电解,可节省PCB布局空间,适配高密度集成设备(如小型通信模块、工业控制器)。
电解电容为有极性器件,安装时需核对电容负极侧的白色条纹标识与PCB极性标记(通常为“+”“-”或丝印),反向安装会导致电容瞬间损坏。
覆盖**-55℃~+105℃**宽温区间,可适配:
10000小时@105℃——属于长寿命级别(普通贴片电解通常为2000~5000小时@105℃),可支持设备7×24小时长期运行(如UPS电源、通信基站)。
经过高低温循环、湿热老化、振动测试等行业标准验证,性能稳定,可降低设备故障率。
VKME1451H331MV凭借紧凑尺寸、宽温长寿命的优势,成为中高压贴片电解市场的高性价比选择,可满足多数电子设备的滤波/储能需求。

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.
