MCS0420-2R2MN2功率电感产品概述

一、基础参数与规格

MCS0420-2R2MN2是PSA信昌电陶推出的表面贴装(SMD)功率电感,核心参数精准覆盖中低功率电源电路需求,具体如下:

  • 电感值:2.2μH(微亨),符合功率电感常规取值范围;
  • 精度:±20%,满足工业级电路对电感值的基础一致性要求;
  • 额定电流(I₍rated₎):3A(直流)——指电感在额定工作温度下,电感值变化不超过允许范围的最大连续工作电流;
  • 饱和电流(I₍sat₎):5A(直流)——指电感值下降至初始值80%时的最大电流,为电路瞬时峰值电流提供安全余量;
  • 直流电阻(DCR):52mΩ(毫欧)——电感绕组的直流电阻,低阻值可减少功率损耗;
  • 封装尺寸:4.0mm×4.6mm×2.0mm(长宽高),属于小型化SMD封装,适配自动化贴装工艺。

二、核心性能特点

  1. 低损耗高转换效率
    52mΩ的DCR在同封装电感中处于优势水平:当工作电流为3A时,功率损耗仅约0.468W(计算方式:I²R=3²×0.052),可有效降低电源模块热损耗,提升能效,尤其适合电池供电的便携设备。

  2. 充足电流余量
    额定电流3A覆盖多数中低功率场景(如5V/3A充电模块),饱和电流5A可应对负载突变、启动瞬间的峰值电流(如手机快充启动时的瞬时电流),避免电感饱和导致电感值骤降,保障电路稳定性。

  3. 小型化设计
    4.0×4.6×2.0mm的紧凑封装,可节省PCB板空间30%以上(对比传统5×5mm封装),适配消费电子轻薄化趋势(如无线耳机、智能手表的电源模块)。

  4. 宽温可靠性
    产品设计兼顾-40℃~+85℃工作温度范围(具体可参考PSA官方 datasheet),满足不同环境下的稳定工作需求(如户外传感器、车载辅助模块)。

三、封装与适用场景

该电感采用SMD表面贴装封装,焊盘尺寸符合行业标准,支持回流焊、波峰焊等自动化生产工艺,适合批量制造。主要适用场景包括:

  • 消费电子:智能手机、平板电脑的DC-DC转换电路(5V转3.3V/12V)、无线充电器的滤波模块;
  • 小型家电:智能插座、加湿器、扫地机器人的电源管理单元;
  • 工业控制:小型PLC模块、低功率电机驱动电路、传感器节点的电源滤波;
  • 通信设备:路由器、交换机的辅助电源电路、信号滤波电路。

四、品牌与品质保障

PSA信昌电陶是国内专业被动元器件制造商,专注电感研发10余年,品质管控体系完善:

  • 产品符合RoHS、REACH环保指令,无铅无镉;
  • 每批次经过电感值、DCR、电流特性等12项测试,一致性达99%以上;
  • 针对汽车电子、工业级场景提供定制化参数(如耐高温、高可靠性版本)。

五、选型注意事项

  1. 电流匹配:实际连续工作电流需≤3A,峰值电流≤5A,避免过载导致电感饱和或温升过高;
  2. 空间适配:确认PCB焊盘尺寸与4.0×4.6mm匹配,预留1mm以上散热间隙;
  3. 精度需求:±20%精度适合电源滤波、DC-DC转换,若需更高精度(如±10%)需咨询PSA定制;
  4. 温度环境:若应用温度超过85℃,需选择PSA耐高温版本(如-40℃~+125℃)。

该产品凭借“小体积、低损耗、高电流余量”的特点,成为消费电子、小型工业设备电源电路的高性价比选择。

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
