KM1H220M0511直插铝电解电容产品概述

一、产品基本定位与核心参数

KM1H220M0511是容强(ROQANG)品牌推出的通用型径向直插铝电解电容,针对中低功率电子电路的滤波、耦合等基础需求设计,核心参数明确且适配多数常规场景:

  • 标称容值:22μF(微法,属于通用中容值范围)
  • 容值精度:±20%(铝电解电容常规精度等级,满足非超高精度电路需求)
  • 额定电压:50V DC(直流电压上限,提供安全裕量)
  • 纹波电流能力:78mA(@120kHz频率下的耐受值,适配开关电源常用频率)
  • 封装形式:径向引线(引脚从电容体两端垂直引出,便于PCB插件安装)

二、关键性能指标详解

铝电解电容的核心性能集中在容值稳定性、纹波耐受、电压承载,本产品针对性设计适配通用场景:

  1. 容值与精度:22μF的标称值覆盖电源滤波、音频耦合等典型需求,±20%精度避免了不必要的成本冗余,适合对精度要求不苛刻的电路。
  2. 纹波电流能力:78mA(120kHz)是关键性能点——铝电解电容的纹波耐受直接影响寿命(纹波过大会加速内部发热老化)。120kHz为开关电源主流工作频率,该指标确保产品在典型电源场景下稳定运行。
  3. 额定电压:50V DC远高于常规低压电路(12V/24V)的电压需求,可满足工业控制、小型电源等中压场景的安全工作要求。

三、封装与尺寸规格

本产品采用紧凑径向封装,适配常规PCB设计:

  • 电容体直径(D):5mm(小型化设计,便于高密度PCB布局)
  • 电容体长度(L):11mm(不含引脚,整体尺寸小巧)
  • 引脚间距:2mm(符合插件电容标准,简化PCB焊盘设计)
  • 引脚形式:直插式(支持手工焊接或自动插件设备安装)

该尺寸在保证性能的前提下,最大程度减少了对PCB空间的占用,适合小型化电子设备(如小型电源、车载电子)的集成需求。

四、工作环境与寿命特性

KM1H220M0511具备宽温范围与可靠寿命,适应多样化场景:

  • 工作温度:-40℃~+105℃(覆盖工业级环境,可在低温户外、高温密闭机箱中稳定工作)
  • 工作寿命:2000小时@105℃(105℃高温下连续工作时长,常温25℃下寿命可延长至数万小时,满足多数电子设备使用寿命要求)

注:实际寿命随工作温度降低、纹波电流减小而显著延长,需避免超过额定电压与纹波电流使用。

五、典型应用场景

结合参数与性能,本产品适用于以下常见电路:

  1. 开关电源滤波:手机充电器、LED驱动电源、小型适配器的输出滤波(适配120kHz开关频率)
  2. 音频电路耦合:小型功放、收音机的信号耦合(中容值匹配音频频率范围)
  3. 工业控制电路:PLC模块、传感器接口的供电滤波(宽温范围适应工业环境)
  4. 消费类电子:小型家电(豆浆机、加湿器)、智能家居设备的电源电路(紧凑尺寸适配小型化设计)

六、品牌与可靠性说明

本产品由容强(ROQANG)品牌生产,该品牌专注铝电解电容研发制造,产品符合常规质量标准:

  • 采用优质铝箔与电解液,确保容值稳定性与寿命可靠性
  • 引脚镀锡工艺,抗氧化性强,焊接牢固且便于操作
  • 电容体阻燃外壳(常规V0级,符合安全规范)

需注意:本产品为通用型电容,不建议用于高频(>1MHz)、高精度(±10%以内)或高纹波电流(>78mA@120kHz)的特殊场景。

综上,KM1H220M0511是一款性价比突出的通用直插铝电解电容,可满足多数中低功率电子设备的基础电容需求。

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
