KM1V221M0812直插铝电解电容产品概述

KM1V221M0812是容强电子(ROQANG)推出的一款中低压径向引线直插铝电解电容,针对体积紧凑、纹波抑制稳定的电子设备设计,核心平衡了电气性能、可靠性与成本控制,适用于工业控制、消费电子、车载及通信等多领域。

一、产品核心定位与设计思路

该电容以“小体积适配紧凑空间+中低压场景稳定工作”为核心目标,针对中小功率电源系统的滤波、耦合需求优化参数:既避免过高性能冗余导致成本上升,又通过宽温区、高温寿命验证确保工业级可靠性,是替代传统大体积电容的高性价比选择。

二、关键电气性能参数详解

1. 容值与精度

标称容值220μF(标识“221”对应22×10¹μF),精度±20%,满足一般滤波、耦合电路的容值需求——对于开关电源输出滤波,容值偏差在±20%范围内不会影响输出电压稳定性,无需额外校准,降低系统设计复杂度。

2. 额定电压与裕量设计

额定电压35V,比常见的12V、24V直流电源系统高出11V~23V,预留充足电压裕量:可有效应对电源波动、瞬态过压等情况,避免电容因过压击穿损坏,提升系统抗干扰能力。

3. 纹波电流耐受能力

高频纹波电流参数为270mA@120kHz,120kHz是开关电源(如反激式电源)的典型工作频率,直接决定电容的纹波抑制能力:对于输出电流1A2A的中小功率电源,输出滤波电容的纹波电流需求通常在200mA300mA,270mA的耐受值刚好匹配,可有效降低输出纹波电压,提升电源品质。

4. 寿命与可靠性参数

工作寿命标称2000hrs@105℃,符合铝电解电容行业标准测试条件(高温连续工作验证)。实际应用中,若设备工作温度为85℃(工业设备常见环境),寿命可延长至约8000hrs(铝电解电容寿命随温度每降低10℃翻倍),满足多数工业设备5年以上使用寿命要求。

三、物理结构与封装特性

1. 封装形式与引脚规格

采用径向引线直插封装,引脚间距3.5mm,符合PCB标准插件焊盘设计,焊接工艺兼容性强(手工焊、波峰焊均可),无需特殊治具即可批量生产。

2. 体积规格

电容体直径8mm,长度12mm(不含引脚),属于小体积铝电解电容范畴:相比同容值同电压的10mm直径电容,体积缩小约36%,可适配空间紧凑的设备(如小型车载充电器、路由器电源模块)。

3. 引脚设计

引脚采用镀锡铜材质,抗氧化性强,焊接时不易出现虚焊、假焊;引脚长度经优化,便于PCB插入与固定,降低组装难度。

四、环境适应性与可靠性验证

1. 宽温工作范围

工作温度覆盖**-40℃~+105℃**,满足极端环境需求:

  • 低温场景(北方户外通信设备、车载低温启动):电容性能稳定,无容值骤降或失效风险;
  • 高温场景(工业控制柜、电源内部发热区):可长期工作,无需额外散热设计。

2. 可靠性测试

产品通过以下标准验证:

  • 高温寿命测试:105℃下连续工作2000hrs,容值变化≤±20%,损耗角正切值(tanδ)变化≤50%;
  • 低温特性测试:-40℃放置24hrs后,容值变化≤±30%;
  • 耐电压测试:施加43.75V(1.25倍额定电压)直流电压1min,无击穿、漏电流正常。

五、典型应用领域

KM1V221M0812的参数特性适配多场景:

  1. 中小功率开关电源:输出/输入滤波(配合陶瓷电容实现高低频纹波抑制);
  2. 工业控制设备:PLC模块、传感器节点的电源滤波,宽温区适配工业现场;
  3. 车载电子:车载充电器、仪表盘电源,满足-40℃低温启动与高温工作;
  4. 消费电子:小型充电器、机顶盒、路由器的电源部分,小体积适配紧凑设计;
  5. 通信设备:小型基站、无线AP的辅助电源滤波,提升信号稳定性。

总结

KM1V221M0812直插铝电解电容凭借小体积、宽温区、中低压裕量及匹配的纹波电流能力,成为工业与消费电子领域的高性价比选择,可有效满足中小功率电源系统的滤波需求,同时降低系统设计与成本压力。

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.

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.
