ROQANG KM1V221M0810 插件铝电解电容产品概述

一、产品基本定位与核心参数

ROQANG(容强)KM1V221M0810是一款低压直插铝电解电容,主打消费电子、小家电及工业控制场景的电源滤波、耦合需求,核心参数平衡了性能与成本:

  • 标称容值:220μF(型号中“221”表示22×10¹μF);
  • 容值精度:±20%(铝电解常规精度,适配多数非高精度电路);
  • 额定电压:35V DC(覆盖12V/24V等常见低压直流系统);
  • 工作温度:-40℃~+105℃(宽温设计,应对高低温环境变化)。

这些参数无需额外冗余设计,能满足90%以上常规电路的滤波要求。

二、封装与尺寸规格

产品采用插件直插封装,电容体尺寸为「直径8mm×长度10mm」(D8×L10),引脚间距约2.5mm(行业标准),适配性强:

  • 尺寸小巧:8mm直径+10mm长度,可轻松塞进小型电源模块、小家电控制板等紧凑空间;
  • 焊接便捷:直插引脚无需特殊设备,手工或自动插件机均可快速装配,降低生产难度;
  • 引脚适配:引脚材质为镀锡铜,焊接牢固,不易氧化。

需注意:引脚长度需根据PCB板厚度裁剪,避免过长短路或过短虚焊。

三、电气性能与可靠性

作为铝电解电容,KM1V221M0810的核心性能稳定可靠:

  • 滤波能力:220μF容值搭配35V电压,能有效滤除开关电源的高频纹波,提升电路供电纯净度;
  • 温度稳定性:-40℃~+105℃范围内,容值变化率控制在±15%以内(铝电解常规标准),低温不“冻僵”、高温不“衰减过快”;
  • 可靠性指标:常温漏电流≤5μA(参考品牌标准),长期使用不易鼓包、漏液;105℃下寿命≥1000小时(温度每降10℃,寿命加倍,实际场景寿命更久);
  • 损耗控制:损耗角正切(tanδ)≤0.12(120Hz/20℃),满足常规滤波场景的效率要求。

四、典型适用场景

参数与封装特性决定了它的适配范围,以下是核心应用:

  1. 小型开关电源:手机充电器、路由器/交换机电源、LED驱动电源(12V/24V输出滤波);
  2. 小家电控制板:电饭煲、微波炉、电热水壶(厨房100℃左右环境适配);
  3. 工业控制模块:PLC辅助电源、传感器电路(宽温应对工业现场高低温);
  4. 消费电子终端:机顶盒、游戏机、智能音箱(紧凑尺寸适配小型化设计)。

避坑提醒:不适合高压(>35V)、高频(>100kHz)或大纹波电流(如大功率逆变器)场景。

五、选型与使用注意事项

为延长寿命、避免失效,需注意3个关键点:

  1. 电压降额:实际工作电压≤28V(额定电压80%),避免过压击穿;
  2. 焊接规范:焊接温度≤260℃、时间≤3秒,防止电解液变质;
  3. 环境适配:避免长期浸泡在液体中,远离强磁场(铝电解对磁场敏感)。

若用于高温场景(如105℃),可适当降低工作电压(如≤24V),进一步提升寿命。

六、品牌与品质保障

ROQANG(容强)是国内铝电解电容领域的成熟品牌,KM1V221M0810的品质管控严格:

  • 生产管控:每批次经过容值、漏电流、温度循环测试,合格率≥99.5%;
  • 环保合规:符合RoHS 2.0标准,无铅引脚适配环保焊接;
  • 供货支持:常规型号备有库存,小批量样品(100只起)可当天发货,大批量订单交期≤7天。

综上,KM1V221M0810是一款“够用、好用、不贵”的低压插件电容,适合多数常规电路的滤波与耦合需求。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
