该产品为永铭电子(Ymin)推出的通用型贴片铝电解电容,核心参数如下:
2000hrs@105℃是该产品的核心寿命指标——在105℃极端高温下,连续施加额定电压工作2000小时后,容值变化率≤±20%、损耗角正切值(tanδ)≤初始值150%,满足工业级设备(如车载电子、高温电源模块)的长期稳定需求。
610mA@100kHz的纹波电流能力,针对开关电源常见的100kHz高频纹波设计,可有效抑制输出端电压波动,提升电源效率与负载稳定性(适用于LED驱动、适配器等开关电路)。
-55℃~+105℃的温宽覆盖了寒冷户外(如北方户外设备)、高温工业现场(如烤箱控制电路)等场景,避免低温容值衰减、高温漏电流增大的问题,保证全温区性能一致。
220μF容值+35V耐压的组合,兼顾了容量(储能/滤波需求)与耐压(安全余量),适合中等功率电路的滤波、耦合与储能(如DC-DC转换器输出滤波、音频电路耦合)。
该产品采用SMD贴片封装,优势在于:
设计PCB时需注意:预留焊盘间距(避免高温下封装应力),并确保散热间隙(满足105℃工作温度的散热需求)。
结合参数特性,该产品主要应用于:
Ymin(永铭电子)是国内专业铝电解电容制造商,拥有10余年研发生产经验,产品覆盖通用型、高频低阻型、长寿命型等系列,广泛应用于工业、消费、车载领域。该产品通过RoHS环保认证,符合无铅焊接要求,且经过温度循环、湿热老化、振动测试,保证批量产品一致性。
若需替代该产品,需匹配核心参数:
常见替代品牌包括Rubycon(红宝石)、Nichicon(尼吉康)的同规格产品,需根据成本与供货周期选择。
V3MCC0771V221MVTM作为通用型贴片铝电解电容,凭借宽温特性、高温寿命与高频纹波能力,适用于多种中低压电路场景,是工业与消费电子领域的可靠选型。

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.
