VMMD0791H101MV 贴片铝电解电容产品概述

一、核心参数概览

VMMD0791H101MV是永铭(Ymin)推出的工业级贴片铝电解电容,核心参数精准匹配中低压、中等容值的电路设计需求,具体如下:

  • 容值:100μF(标注“101”对应10×10¹=100μF,铝电解电容常用三位数字标注容值);
  • 精度:±20%(兼顾成本与性能,满足多数常规电路的滤波、储能需求);
  • 额定电压:50V(直流额定电压,覆盖12V/24V/48V等主流电源系统的电压区间);
  • 封装尺寸:电容体直径8mm,长度7.9mm(SMD贴片封装,尺寸标注为8×7.9mm,不含引脚);
  • 类型:铝电解电容(具备高容值密度、成本优势,区别于陶瓷电容的高压容值衰减特性)。

二、产品特性解析

这款电容的设计聚焦自动化生产适配性与场景兼容性,核心特性包括:

  1. 贴片封装适配SMT工艺:SMD封装无需插件工序,可直接贴装于PCB表面,兼容回流焊/波峰焊(需控制焊接温度),大幅提升生产效率,降低人工成本;
  2. 中容值密度平衡:100μF容值在8mm直径封装内实现,避免过度占用PCB空间,适配高密度主板设计;
  3. 宽电压场景覆盖:50V额定电压可满足消费电子、工业控制的二次电源滤波需求,无需额外降额设计;
  4. 成本与性能均衡:±20%精度无需高精度规格的额外成本,适合批量应用场景(如电视机、路由器等消费电子)。

三、封装与尺寸说明

SMD封装是这款电容的核心设计,具体尺寸与贴装要求如下:

  • 本体尺寸:电容体直径8mm,长度7.9mm(不含引脚,引脚高度约1mm,实际贴装高度需参考官方 datasheet);
  • 焊盘设计:需预留5mm左右的电极间距(匹配8mm直径的引脚分布),焊盘尺寸建议≥1.2mm×1.2mm(避免虚焊);
  • 工艺兼容性:适配常规SMT贴片机,无需特殊工装,可与电阻、陶瓷电容等元件同线生产,降低产线切换成本。

四、典型应用场景

结合参数特性,这款电容适用于以下主流场景:

  1. 电源滤波电路:线性电源/开关电源的输出滤波(100μF容值可有效滤除100Hz以下低频纹波,50V电压满足多数电源输出上限);
  2. 消费电子主板:电视机、机顶盒、路由器等设备的电源模块(贴片封装适配自动化组装,体积紧凑);
  3. 工业控制电路:PLC、传感器模块的辅助电源滤波(±20%精度满足工业级常规需求,耐温特性适配-40℃~+85℃工作环境);
  4. 小型储能电路:LED驱动电源的瞬态储能(支持负载峰值电流需求,避免电压跌落)。

五、品牌与可靠性说明

永铭(Ymin)作为国内铝电解电容头部厂商,产品可靠性经过行业验证:

  • 寿命指标:常规工作温度(-40℃+85℃)下,寿命可达1500小时(具体以 datasheet 为准),满足消费电子35年使用周期;
  • 温漂特性:容值随温度变化率控制在±15%以内(在-20℃~+85℃区间内),避免极端温度下性能衰减;
  • 耐纹波能力:可承受最大纹波电流约0.5A(120Hz下),满足开关电源的纹波抑制需求(具体参数需参考官方 datasheet)。

六、选型注意事项

  1. 极性识别:铝电解电容为有极性元件,贴装时需注意电容体上的“+”号标识(或色带),反向焊接会导致电容击穿损坏;
  2. 焊接温度:回流焊峰值温度需控制在260℃以内(持续时间≤10秒),避免高温损坏电容电解液;
  3. 降额设计:若工作电压接近50V,建议采用20%降额(实际工作电压≤40V),延长电容寿命;
  4. 对比选型:与同规格直插电容相比,贴片封装体积缩小30%以上;与陶瓷电容相比,高压下容值无明显衰减,更适合中低压大容值场景。

总结

VMMD0791H101MV以紧凑尺寸、均衡的参数特性和高性价比,成为消费电子、工业控制等领域电源电路设计的常用选型。其贴片封装适配自动化生产,50V/100μF的核心参数可有效满足常规滤波、储能需求,是中小批量电路设计的可靠选择。

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.
