VT1E221M0810 贴片铝电解电容产品概述

一、产品基本定位与品牌背景

VT1E221M0810是容强(ROQANG)品牌推出的一款通用型贴片铝电解电容,主打中低压、中等容值的滤波/储能场景,适配自动化贴装生产需求,广泛应用于消费电子、工业控制等领域。作为国产铝电解电容的主流品牌之一,容强在SMD封装产品的可靠性与成本控制上具备成熟经验,该型号是其常规产品线中的核心规格之一。

二、核心电气参数解析

1. 容值与精度

容值为220uF(型号中“221”代表22×10¹=220uF),精度±20%——满足绝大多数通用电路对容值偏差的要求,无需高精度校准即可覆盖电源滤波、耦合等场景,平衡了性能与成本。

2. 额定电压与耐压能力

额定电压25V(型号中“E”对应25V电压等级),属于中低压范畴,可覆盖5V-25V的电路供电系统,建议实际工作电压留1.2-1.5倍余量(如≤20V),避免过压击穿。

3. 纹波电流与散热能力

纹波电流参数为183mA@120Hz——120Hz是整流后电源纹波的典型频率,该参数反映电容在交流纹波下的散热能力:183mA的水平可有效抑制常规电源电路的低频纹波,减少电容发热导致的寿命衰减,适配开关电源输出滤波、线性电源稳压后滤波等场景。

4. 温度与寿命特性

  • 工作温度范围:-40℃~+105℃(宽温设计),低温下容值变化率符合行业标准,高温下电解液挥发慢,适配车载、户外、工业极端温度环境;
  • 工作寿命:2000hrs@105℃——105℃高温连续工作2000小时仍保持性能,换算成25℃常温下寿命约51万小时(≈58年),满足长期稳定运行需求。

三、结构与封装特性

1. 封装形式与尺寸

采用SMD贴片封装,电容体尺寸为D8mm×L10.2mm(直径8mm,长度10.2mm),属于小型化设计,节省PCB空间,适配紧凑式电子设备(如智能手机、小型家电控制板)。

2. 结构设计

卷绕式铝电解结构(铝箔卷绕+电解液+引出端),SMD封装通过焊盘与PCB连接,避免插件式手工焊接,提升生产效率;焊盘设计匹配标准SMD电容规范,无需特殊定制。

3. 极性标识

铝电解电容带极性,需注意PCB极性标识与电容引脚(通常长脚为正极)一致,反向焊接会导致击穿甚至爆炸。

四、性能优势与可靠性

1. 宽温稳定性

-40℃~+105℃范围内,容值偏差控制在±20%以内,低温(-40℃)下容值下降不超过30%,高温(105℃)下漏电流稳定,避免电路失效。

2. 纹波抑制能力

183mA@120Hz的纹波电流,可有效降低电源输出纹波(如开关电源输出纹波可控制在50mV以内),提升后级电路(如MCU、传感器)的工作稳定性。

3. 性价比优势

在同规格SMD铝电解中,容强该型号的成本控制较好,适合批量采购的电子厂商,降低BOM成本。

五、典型应用场景

  1. 消费电子:智能手机/平板的电源滤波、便携式音频设备的耦合电路、智能台灯/加湿器的控制板电源;
  2. 工业控制:PLC辅助电源滤波、传感器模块滤波、小型变频器直流母线滤波;
  3. 车载电子:车载充电器、行车记录仪的电源电路(非安全关键场景);
  4. 通信设备:小型路由器/交换机的电源模块滤波、机顶盒电源电路。

六、选型与使用注意事项

  1. 耐压余量:实际工作电压需≤20V(留1.2倍余量),避免过压损坏;
  2. 纹波匹配:若电路纹波电流超过183mA@120Hz,需并联多个电容或选择更高纹波电流型号;
  3. 贴装规范:回流焊温度≤260℃,时间≤10秒,避免电容受热老化;焊盘尺寸需匹配(直径≥电容引脚直径,间距符合SMD标准);
  4. 极性确认:焊接前需核对PCB极性标识与电容引脚极性,严禁反向焊接。

VT1E221M0810凭借宽温、长寿命、小型化的特点,成为通用电子设备电源滤波的高性价比选择,适配多数中低压电路的实际需求。

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.
